There are many aspects to medicine included in the show.
Illnesses and Conditions[]
A.L.I.E.'s residual code[]
After being freed from A.L.I.E.'s control using an EMP in "Nevermore" and "Perverse Instantiation (Part 2)" respectively, Raven Reyes and Abigail Griffin are left with remnants of the AI's code in their head. Raven compares using an EMP to free them to pulling the plug on a computer to shut it off, resulting in the leftover code. This increases their brain function and Raven's intelligence. Both Raven and Abby have visions suggesting a possible degree of precognition as Raven sees the rocket on Becca's Island before actually learning of its existence and Abby has visions of a radiation-burned Clarke. As time goes on, the condition causes seizures and hallucinations and eventually death as the code is too much for the human brain to handle long-term. While Raven was left with only beneficial side effects once the condition was cured, Abby was left with chronic headaches that contributed to Abby's later drug addiction.
In "Demons," Raven discovers the first indication of this condition, or rather the beneficial aspects of it, when she can understand the programming code in Becca Franko's notebook which is not a programing language that Raven was ever taught.
In "The Tinder Box," Raven's condition is discovered after she has a seizure and Abby and Eric Jackson perform a brain scan on her while Raven is actively using a huge percentage of her brain. They also find signs of a possible stroke and Abby suggests that A.L.I.E. was right about the EMP causing brain damage. Raven realizes that it's a result of her chip being fried with an EMP rather than being disconnected when Clarke pulled the master kill switch. Abby suggests that Becca's mind was in the residual code which is why Raven knew about the rocket and warns Raven that the condition will kill her if she keeps going, but Raven is unwilling to stop. Jackson expresses concern that Abby could have the same condition as she was also disconnected from A.L.I.E. by an EMP, but Abby brushes off his concerns, stating that brain trauma can cause entirely different symptoms in different people. Abby refuses to be tested as well, but she later suffers a hallucination of a radiation-burned Clarke warning her mother that Abby doesn't have much time.
In "The Other Side," a hallucination of Jacapo Sinclair convinces Raven, nearly about to give up for good, to try to find a solution. With the help of Sinclair, Raven realizes that "rebooting" her brain would purge the code, but would require her heart to be stopped for 15 minutes. Raven devises a way to use an ice bath to freeze and revive herself while preserving her brain function. The treatment works, purging the code and ending Raven's seizures and hallucinations, but also restoring her intellect to normal.
In "The Chosen," Raven informs Abby of the treatment and states that it worked: her seizures have stopped and her brain is healing. Raven intends to perform the same treatment on Abby when she gets to the Second Dawn Bunker, but she never gets the chance to.
In "Red Queen," Eric Jackson grows concerned when Abby gets headaches as she took the ice bath treatment which was supposed to stop them. Abby just tells Jackson that they will stop in time.
In "How We Get to Peace," Abby reveals to Raven that despite being cured, she was left with chronic pain, causing Abby to eventually become a drug addict.
In "The Blood of Sanctum," its revealed that Raven retains the hacking skills that she got while having A.L.I.E.'s code in her head despite it all being long-since purged.
Cancer[]
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.
Before the first Nuclear Apocalypse, Becca Franko conducted research in her lab with a radiation chamber in an effort to find a cure for cancer.
A.L.I.E. warned that pre-cancerous lesions is one of the warning signs for the incoming Second Nuclear Apocalypse.
Dr. Gabriel Santiago, despite being a Nightblood, suffered from terminal cancer in his original body and later died from it before being resurrected by Josephine Lightbourne. According to Josephine, Gabriel was already dying of cancer by the time that he resurrected her using a Mind Drive.
Fungal crop disease[]
The hydrofarm in the Second Dawn Bunker was infected by a fungus that ruined much of the protein crops, leading to the Dark Year where Wonkru was forced to resort to cannibalism in order to survive while new crops were grown. While the hydrofarm eventually became functional again, most of it remained infected with the fungus. Monty Green was eventually able to find a solution using the nitrogen in the toxic strain of his algae.
In "The Dark Year," in a flashback, Kara Cooper discovers the fungus problem, leading to the events of the Dark Year as the bunker's inhabitants attempts to survive the crisis.
In "How We Get to Peace," Monty and Cooper treat the hydrofarm using Monty's algae to a great deal of success. Monty predicts that they could have the entire farm cured in a week and Cooper compliments his talent. Monty presents the repair of the hydrofarm as an alternative to taking Shallow Valley to Cooper, but their discussion is interrupted by Clarke and Bellamy.
In "The Warriors Will," Monty reveals that he succeeded in fixing the hydrofarm with his algae, but it is burned down by Octavia in order to force Wonkru to march on Shallow Valley.
Flu[]
Influenza, commonly known as the Flu, is an infectious disease with the most common symptoms being high fever, runny nose, sore throat, muscle and joint pain, headache, coughing and feeling tired.[1]
In "The 48," John Murphy reveals to Raven Reyes that when he was a child, he got the flu and his father stole medicine that it turns out wouldn't have helped anyway to treat him. Murphy recovered, but his father got floated for the theft, causing his mother to turn to alcoholism and blame Murphy for his father's death before she drank herself to death.
PTSD[]
Post-Traumatic Stress Disorder, also known as PTSD, is a condition caused by experiencing a particularly traumatic event. Symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress to trauma-related cues, attempts to avoid trauma-related cues, alterations in how a person thinks and feels, and an increase in the fight-or-flight response. These symptoms last for more than a month after the event.[2]
After being speared in the chest in "Pilot" and nearly dying, Jasper Jordan shows signs of PTSD in "Murphy's Law," being reluctant to leave the safety of the Delinquents' Camp. He continues to battle PTSD throughout the first and second seasons.
Clarke Griffin suffers from post-traumatic stress disorder from her father's death, causing her to have a deep desire to save everyone because she couldn’t save her father. Because of this, starting at the beginning of Season One, Clarke has shown signs of her rude, arrogant, and aggressive behavior, due to her PTSD. She also suffers PTSD from the deaths of many people she cares for and the Mountain Men, which made her post-traumatic stress even worse. After six years of near-isolation due to the Second Nuclear Apocalypse, Clarke became ruthless and single-minded in her desire to protect Madi, siding with Paxton McCreary and the Eligius Prisoners to fight against Octavia, suggesting that the PTSD had made her darker, though Clarke became remorseful of the actions that she did. This triggers her PTSD even worse again, causing her to suffer in grief and become even suicidal as well. When Abby revealed that she was responsible for the "Dark Year" and for Octavia's dark nature, Clarke shows no sign of anger towards her and still loves her as she said to Madi that Octavia killed the people in the bunker, suggesting that Clarke has shown signs of PTSD, due to the alterations in how she thinks and feels. In the beginning of Season 7, Clarke also begins to suffer a post-traumatic stress from her mother's death.
Other characters suffer from Post-Traumatic Stress disorder from all the events that have happened.
Finn Collins suffers from post-traumatic stress disorder that causes him to become hardened.
Octavia suffers post-traumatic stress disorder from the events of the "Dark Year" in the bunker when she executed three people for refusing to cannibalize, forcing many Wonkru to cannibalize as well. In the aftermath, Octavia becomes hardened, during six years in the bunker, where the events there become more worse.
Abby suffers post-traumatic stress after she forced Octavia to punish those for not cannibalizing. Abby's actions has led to her own mental illness and her drug addiction. Now fearing Octavia, her PTSD causes her to help heal Paxton McCreary's men to allow them to fight against Octavia. On Eligius IV, Abby's PTSD causes her to become even more reckless and careless, when she did not help Octavia when she was beaten up by the Sky People, and fearing the loss of Marcus Kane, Abby allows Simone Lightbourne to mind-wipe Gavin to use his body as a host for Kane to save him.
James Crockett appears to have suffered from PTSD due to his mother's death and he blames Octavia for it. Despite Marcus Kane's involvement with his mother's death, he is shown sitting next to him, suggesting that he has shown signs of PTSD, due to the alterations in how he thinks and feels, but it is unknown if he still holds a grudge on him or if he still hates him. Despite Abby being responsible for Octavia's dark nature that led to the death of his mother and helping Paxton McCreary heal his men to allow them to fight against Octavia that also led to his mother's death, James complies with Abby telling him not to go aggressive on Octavia and not to kill her, which also suggests that he has shown signs of PTSD, due to the alterations in how he thinks and feels.
Marcus Kane suffers post-traumatic stress from the events of the bunker, due to Octavia's actions. This causes him to fear Octavia and betray Spacekru, to help give the battle plans to McCreary, in order to prevent Octavia from controlling Shallow Valley. Kane has shown signs of PTSD, due to the alterations in how he thinks and feels when, after being attacked by Vinson, a wounded Kane reveals to Abby that he knows that that she was responsible for the "Dark Year" and Octavia's dark nature as he both forgives Abby and blame Octavia for the death of three people in the bunker, and on Eligius IV, he blames Octavia for the massacre in the gorge, even though Kane was truly responsible for it.
Raven suffers post-traumatic stress disorder after receiving a nerve damage in her left leg from a gunshot injury she received when John Murphy shot her on the dropship, watching the death of Finn Collins, and being tortured by the Mountain Men when they begin harvesting her bone marrow. Raven continues to struggle with her pain. She also suffers from PTSD after seeing and watching Hatch and the other prisoners die of radiation poisoning in the reactor.
In the past, Ash had suffered post-traumatic stress after she killed her best friend "Echo", in which she took her name. Her best friend's death had hardened and haunted her ever since. However, after escaping the Second Nuclear Apocalypse, it took several years to heal her emotions.
After being psychologically and emotionally-scarred by the departure of her mother and Octavia and being isolated for ten years, Hope Diyoza watches her friend, Dev, get killed by the Disciples, causing her to suffer a post-traumatic stress. When her mother was killed when she was crystallized by Gem9, this causes Hope to suffer a post-traumatic stress over her role in her mother's death.
It is implied that Charmaine Diyoza has a post-traumatic stress disorder when she was a military soldier and a terrorist, during the conflicts, when she still has a reckless behavior and personality, which led to her preventing Octavia from leaving the Skyring, and aggressively criticizing and arguing with Hope for rescuing her.
In "Etherea," a Disciple experiences PTSD from witnessing the explosion in "Welcome to Bardo" that apparently killed Bellamy Blake. As Levitt treats the Disciple using M-Cap, he discovers that Bellamy was instead blown backwards through the Temporal Anomaly and is in fact still alive.
In "The Dying of the Light," due to Bellamy's death and Madi's departure, Clarke's worsening post-traumatic stress causes her to ignore Jordan's beliefs of the test that can lead to Transcendence and express her hatred towards Bellamy, claiming that he died because Bellamy believed in that "crap" and that she heard enough.
In "The Last War," after meeting with the Judge, Clarke is still unrepentant about her murder during the test, suggesting that she still suffered from PTSD. However, after seeing her group being happy in peace, Clarke begins a new life with them on Earth. This suggests that Clarke will overcome her post-traumatic stress and be able to recover from her years of tragedy, since her friends are now at peace on Earth, which is now a habitable planet.
Radiation Poisoning[]
Maya dies from radiation poisoning.
Radiation poisoning is a condition caused by exposure to radiation. The severity of the condition is dependent on the level of radiation exposure, but it can be lethal with high levels and can lead to a prolonged death. Acute Radiation Syndrome (ARS) is a type of radiation poisoning.
In "Human Trials," Maya Vie is deliberately exposed to radiation by Cage Wallace and Dr. Lorelei Tsing in order to test a possible treatment using Jasper Jordan's blood. The treatment works and Maya recovers.
In "Rubicon," Bellamy Blake, on the direction of Dante Wallace, purposefully irradiates Level 5, causing Tsing and 14 Mount Weather Guards to quickly succumb to radiation poisoning.
In "Blood Must Have Blood (Part 2)," Bellamy and Clarke Griffin with the help of Monty Green irradiate Level 5, once again, killing all of the Mountain Men aside from Cage and Carl Emerson who have both taken the bone marrow treatment that renders them immune to the radiation.
In "The Four Horsemen," Floukru gets ARS from eating irradiated fish. All but Luna die from it with Luna recovering only due to her Nightblood.
In "The Chosen" and "Praimfaya," Clarke Griffin suffers from radiation poisoning after giving up her radiation suit's helmet to Emori. Clarke's Nightblood eventually allows her to recover.
In "False Gods," John Murphy and Emori both develop radiation poisoning while fixing Sanctum's nuclear reactor as do Hatch and the other Eligius prisoners working on the cooling system. Though Raven expected them to only become sick for a few days, the radiation levels prove to be lethal and she chooses to lie to the prisoners who succumb one by one, though Hatch finishes the job at the last second with Murphy's help.
In "Welcome to Bardo," Murphy and Emori, who are both Nightbloods, recover from their radiation poisoning with the help of Eric Jackson. However, Emori takes longer to recover than Murphy causing Jackson to explain that "recovery from radiation exposure doesn't always progress in a straight line" and that Emori will be fine with enough time. She later fully recovers.
In "Anaconda," Tristan, a young Second Dawn cultist, suffers a leak in his radiation suit two years after the Nuclear Apocalypse and as a result, contracts terminal radiation sickness. Upon seeing this, Becca Franko injects Tristan with her Nightblood serum and he is eventually able to recover when Tristan should have died.
Heart Murmur[]
A heart murmur is a medical condition where unique heart sounds are produced when blood flows across a heart valve or blood vessel. Raven Reyes has a heart murmur which initially prevented her from becoming a Zero-G mechanic.
In "Spacewalker," in a flashback, Raven learns that she while she had passed the test with the first perfect score since it was given, she had failed the physical due to Raven's heart murmur. However, after Raven's illegal spacewalk, she learns from Jacapo Sinclair that he had overruled her health rejection due to Raven's talent and she becomes the youngest Zero-G mechanic in 52 years.
In "The Other Side," Raven's hallucination of Sinclair tells her that with Raven's heart murmur, shocking herself as a means of revival at the end of Raven's ice bath treatment could put her into cardiac arrest, meaning that if that happens, Raven will have to shock herself again with a defibrillator to restore a normal rhythm. Raven just quips that it's time for Sinclair to take another chance on a Zero-G mechanic with a heart defect. As predicted by Sinclair, Raven's heart murmur does nearly send her into cardiac arrest once she's revived, but Raven shocks herself with the defibrillator, returning her heartbeat to normal.
Hythylodium sickness[]
A lung disease caused by long exposure to hythylodium. The prisoners from Eligius IV got it from their mining operations, causing them to be abandoned by the Eligius Corporation before their mutiny. It is shown to cause multiple abscesses on the lungs.
Throughout Season Five, the prisoners suffer from the illness, becoming worse and worse over time. In "How We Get to Peace," Doctor Abigail Griffin discovers a treatment while examining Michael Vinson when one of his abscesses suddenly breaks up. Abby realizes that sound waves break up the abscesses and enlists the help of Raven Reyes to build a device to treat the illness. Charmaine Diyoza initially has Abby hide the treatment from Paxton McCreary, but he finds out in "Sic Semper Tyrannis." In "Damocles (Part 1)," Abby finishes treating all of the prisoners.
Hemorrhagic Fever[]
A virus used as a weapon by the Grounders to soften the battlefield. There is no cure, but its not always fatal and can be recovered from. Lincoln states to Octavia that "the sickness passes quickly. Few are immune. We use it to soften the battlefield."
Murphy is infected with the Hemorrhagic fever.
In "I Am Become Death," the Grounders use the virus on the Delinquents to "soften the battlefield" prior to engaging with footmen for hand-to-hand combat. The Grounders infected John Murphy with it and let him escape from their prison camp. Murphy returned to the Delinquents' Camp and infected the Delinquents, causing at least three known deaths. The surviving Delinquents were able to recover on their own and prevented the intended Grounder attack by blowing up the bridge they were crossing.
Wound Infection[]
Typically caused by bacteria getting into a wound, infection can set it and it can become fatal if not properly treated. Over time, it can also progress into septic shock.
In "Earth Kills," Jasper Jordan's spear wound becomes infected and Clarke Griffin tries to treat it by cutting away the infected tissue around the wound. When that fails to stop the infection, she creates a tea out of the seaweed the Grounders use in poultices, successfully allowing Jasper to fight off the infection and survive.
In "Etherea," Bellamy treats Conductor Doucette's broken leg with tree sap, explaining that Charles Pike had taught him that oozing sap from pine trees on Earth can be used to create antiseptic, fight infection and heal wounds. Bellamy expresses hope that the same goes for the trees on Etherea which proves to be the case as Doucette ultimately recovers.
Genetic disorder[]
A genetic disorder, also classified as a hereditary disease, is a health problem caused by one or more abnormalities in the genome. It can be caused by a mutation in a single gene (monogenic) or multiple genes (polygenic) or by a chromosomal abnormality.
In "A Lie Guarded," Clarke Griffin admits to going through Harper McIntyre's medical records and discovering that her father had died of a genetic disorder. As a result, Clarke had kept Harper off of her list out of concern that Harper would eventually develop the same disorder and become a drain on medical resources.
In "Damocles (Part 2)," it's revealed that Harper had her father's genetic condition that causes her to become sick for the last few years onboard the Eligius IV, before dying from it on February 8, 2206.
Ankovirus[]
The Ankovirus Outbreak was seen in the news.
The Ankovirus is new type of disease that is discovered in Russia.
On the eve of the Nuclear Apocalypse, its mentioned that a public health alert has been declared due to an Ankovirus outbreak that originated in Russia.
It is unknown if the victims of the Ankovirus were killed or not when they are sick and infected.
Red Sun Toxin[]
- Main articles: Red Sun Eclipse and Red Sun Toxin
The canister contains the Red Sun toxin.
The Red Sun Toxin is a dangerous toxin that is released from the plants and trees into the air on Sanctum, during the Red Sun Eclipse. It causes a dangerous psychosis that makes people kill each other and experience hallucinations.
In "Red Sun Rising", the toxin is shown to have different effects on each person, targeting a strong personality trait or belief in each and every one. In Murphy, Emori, and Russell, the eclipse targeted their survival instinct in making them want to preserve their own lives by killing everyone around them. In Clarke and Echo, it targets their grief: Causing Echo to hear voices from her past as a spy to the point of sedating herself to make them stop and causing Clarke to hallucinate hearing Abby's voice on a radio trying to convince her to commit suicide. For Bellamy, it targets his inner paranoia: while under the toxin's effect he attacks Murphy and Clarke with the intent to kill, remarked at the times Clarke tried to kill him and repeatedly stating he's protecting everyone by eliminating all the deceivers ("Only I can keep us safe." and "I'm saving us from both of you!") With Miller and Jackson the toxins manipulate their love for each other by causing the two to hallucinate the insects burrowing inside of Miller and leading Jackson to nearly accidentally killing Miller in an attempt to get them out. Finally, when Russell uses the toxin on the people of Sanctum, it turns them violent against each other, separating each other by believers and non-believers.
In "The Children of Gabriel", it is revealed that a seaweed in Sanctum, can release more toxin within the victim, practically killing them, during the Red Sun. The seaweed toxin is deadly, which is more dangerous than the Red Sun toxin.
In "What You Take With You," Gabriel uses red sun toxin to help Octavia remember her time in the anomaly. According to Gabriel, he and Russell Lightbourne once used the toxin in a similar manner to determine if any of the host's mind survived after the implantation of a Mind Drive. The answer was no, but in doing so, they unlocked parts of their own minds, things they'd hidden from themselves, answers about what their greater purpose was. In "Ashes to Ashes," Gabriel explains to Clarke and Bellamy that the toxin is everywhere: in every leaf on every tree, in the soil and the rocks. Over time, the Primes had found other ways to harness its power. Simone weaponized it as part of her Adjustment Protocol while Gabriel focused on developing an anti-toxin.
Sterility and Infertility[]
After the Primes began using their hosts' dormant bodies, it appears that some of them could not bear children, which possibly implies that the mind-wiping drug causes sterility and infertility. This could explain why they didn't have any children and why they couldn't produce any more hosts.
On Bardo, due to the Disciples' strict laws and policies, it is unknown if their embryos were designed to be sterile and infertile when they grow up, in order to prevent them from having their own children while new embryos are being developed many times, every year.
After Clarke's friends had transcended and returned to their human forms, the Judge warns that they cannot have offspring nor bear children, due to their infertility and sterility, which was the result of Clarke's friends transcending and returning back to their mortal forms.
Treatments and Drugs[]
Algae[]
- Main article: Algae
The algae grown by Monty Green is shown to have some medicinal properties with an earlier strain putting people into a coma for a week. However, this could also be used as a form of anesthesia for surgery as seen in "Sanctum."
Monty's algae was also able to fix the Second Dawn Bunker's hydrofarm which had been destroyed by a fungus.
Anesthesia[]
A sedative used to keep someone unconscious, generally during surgery. In "Pilot," Abby Griffin used too much while operating on Chancellor Thelonious Jaha and was nearly floated for it before Jaha pardoned her.
Blood Transfusion[]
The act of transfusing the blood of another into someone. The donor and the recipient must both be compatible or the blood transfusion can have negative effects on the recipient. As part of their Harvest Project, the Mountain Men of Mount Weather use blood transfusions from captured Grounders in an effort to find a solution to their inability to leave the mountain due to their lack of immunity to the radiation outside. In an exchange transfusion, the blood of two people is exchange through tubes, effectively giving each other their blood.
In "Pilot," Abby Griffin uses blood transfusions while treating Chancellor Thelonious Jaha's gunshot wound. As with the anesthesia, Abby uses too much blood per the Ark's rules and was nearly floated for it before Jaha pardoned her.
In "Human Trials," Dr. Lorelei Tsing and Cage Wallace get Jasper Jordan to agree to an exchange transfusion in order to save Maya Vie's life after she gets lethal radiation poisoning.
In "Perverse Instantiation (Part 2)," Clarke Griffin has her mother set up an exchange transfusion with Ontari so that she can make use of the brain dead young woman's Nightblood to use the Flame and destroy A.L.I.E. When Ontari begins crashing, the transfusion starts to fail, forcing John Murphy to manually pump Ontari's heart to keep it going long enough for Clarke to destroy the AI.
In "Sanctum," Abby has all of the surviving Sky People awakened to get enough blood transfusions to help her save Marcus Kane.
In "A Sort of Homecoming," Sheidheda appears to be hooked up to a blood transfusion while talking with Bill Cadogan, who also says that medicine on Bardo is incredible.
Chloroform[]
An organic compound used both as an anesthetic and for criminal use, typically knocking out a kidnapped victim.
In "Die All, Die Merrily," Bellamy Blake is chloroformed in order to be dragged into the Second Dawn Bunker against his will.
In "How We Get to Peace," Bellamy and Clarke Griffin use chloroform to knock out Kara Cooper as part of their plan to kill her using the parasite worms and make it look like an accident.
Coagulant[]
A substance used to help blood clot. Lincoln keeps some in his med kit along with the poison and its antidote.
In "Contents Under Pressure," though not identified as such, the coagulant from Lincoln's med kit is seen as Clarke Griffin tries to find the poison antidote to save Finn Collins.
In "We Are Grounders (Part 2)," Finn seeks out Lincoln's help after Raven Reyes is shot by John Murphy in order to use his coagulant to stop Raven's bleeding and save her life. Lincoln accompanies Finn back to help against the Grounder army and Clarke is able to inject Raven with it as chaos erupts, saving her life for the time being.
In "The 48," Lincoln mentions to Octavia that he can't treat her poisoned wound since he gave his med kit to Finn to save Raven.
Defibrillator[]
Defibrillator
A Defibrillator is a portable medical device use to shock a person's heart usually when they've gone into cardiac arrest to save their life. The rocket in Becca's lab had one in its portable med kit.
In "Long Into an Abyss," Abby Griffin uses a shock baton as a makeshift defibrillator on Lincoln.
In "The Other Side," Raven retrieves the defibrillator from the med kit as part of her plan to purge A.L.I.E.'s residual code by "rebooting" her brain. Raven tells her hallucination of Jacapo Sinclair that she has calibrated the shock that will be given to restart her heart based on the defibrillator from the rocket. Sinclair reminds Raven that with her heart murmur, she may go into cardiac arrest from shocking her heart in such a way and will have to deliver another shock to restore a normal rhythm. Sure enough, after Raven is revived, she begins going into cardiac arrest, but manages to reach the defibrillator in time to shock herself again, returning her heartbeat to normal.
In "The Last War," Raven uses a defibrillator to revive Emori.
Delactivene[]
Delactivene
A drug that can help treat radiation poisoning, but only if administered within the first 24 hours.
In "The Four Horsemen," Abby Griffin and Eric Jackson attempt to use delactivene to treat Floukru even though there's no guarantee it will work given how much time it has been. Raven Reyes, pointing out how much they will need the drug over the next five years, refuses to give any of it up, but it is stolen by John Murphy. The two try delactivene on Adria, but it fails to work and Adria dies. Abby subsequently returns the remainder of the drug to Raven, but the fact that Luna recovered when they didn't try delactivene on her causes Abby to realize that Luna's Nightblood saved her.
Dialysis[]
A process used to remove toxins from a person's kidneys when their body is unable to do it naturally, usually due to injury.
In "Sic Semper Tyrannis," Eric Jackson is able to wake Octavia Blake from her coma by using dialysis to pump the toxin from her system.
In "The Gospel of Josephine," one of the problems facing Abby Griffin with saving Marcus Kane's life is that his kidneys have shut down and he needs full hemodialysis for starters. Abby wants to try a different kind of dialysis, but Jackson points out that Kane's abdominal wounds prevent that. Josephine Lightbourne, posing as Clarke Griffin, uses her experience as a biologist to offer Abby an alternative using a Sanctum insect. However, the procedure that Abby comes up with still won't work as it will take at least 15 hours and Kane only has 10 minutes at most once he is removed from his cryopod.
Drug detoxification[]
Drug detoxification (informally, detox) is variously the intervention in a case of physical dependence to a drug; the process and experience of a withdrawal syndrome; and any of various treatments for acute drug overdose.
Clarke used the detox on Abby to cure her drug overdose.
Sound Wave Treatment Machine[]
Throughout Season Five, after the prisoners suffer from the Hythylodium sickness, becoming worse and worse over time, Doctor Abigail Griffin discovers a treatment while examining Michael Vinson when one of his abscesses suddenly breaks up. Abby realizes that sound waves break up the abscesses as Vinson shows her the Sonic Drill, which will be used to create powerful sound waves. So, Abby enlists the help of Raven Reyes to build a device to treat the illness. Charmaine Diyoza initially has Abby hide the treatment from Paxton McCreary, but he finds out in "Sic Semper Tyrannis." In "Damocles (Part 1)," Abby finishes treating all of the prisoners.
Ice Bath[]
A treatment devised by Raven Reyes to cure the condition that she and Abigail Griffin had gotten from having remnants of A.L.I.E.'s code in their head. Eric Jackson refers to it as the ice bath in "Red Queen."
In "The Other Side," a hallucination of Jacapo Sinclair inspires Raven to seek a cure for her condition by "rebooting" her brain. As this requires Raven's heart to be stopped for 15 minutes, she comes up with the idea of using an ice bath to stop her heart while the cold protects her brain function so that she won't be left brain damaged or dead. Wearing an oxygen mask so that she doesn't drown, Raven attaches a wire to her chest to deliver a shock calibrated using a defibrillator with a timer set for 15 minutes once her heart stops. The treatment works and A.L.I.E.'s residual code is purged, ending Raven's seizures and allowing her brain to heal itself.
In "The Chosen," Raven informs Abby of the treatment and states that it worked: her seizures have stopped and her brain is healing. Raven intends to perform the same treatment on Abby when she gets to the Second Dawn Bunker, but she never gets the chance to.
In "Red Queen," Jackson mentions that Abby took the treatment as well and is worried about her continuing headaches as a result. Abby just tells Jackson that they will stop in time.
Lake Seaweed[]
A seaweed used by the Grounders in a poultice due to its antibiotic properties.
In "Earth Skills," a Grounder that captured Jasper Jordan places a poultice with the seaweed on Jasper's spear wound after cauterizing it. The combination keeps him alive long enough for his friends to rescue him, but fails to prevent infection.
In "Earth Kills," Clarke Griffin takes apart the poultice, believing that whatever's in it can be used to treat Jasper's infection in the form of a tea. Wells Jaha identifies it as seaweed and Finn Collins leads Clarke and Wells to a nearby river. Clarke recovers the seaweed and after a night avoiding Acid Fog, creates a tea with it. The seaweed helps Jasper to fight off the infection and he survives.
In "The Calm," Finn suggests using the seaweed to treat Tris' injuries, but Clarke refuses as she knows that it won't work.
Morphine[]
A drug used to numb pain which can also act as a narcotic and become addicting. During "Murphy's Law," Abby Griffin trades some to Nygel for a pressure regulator and is arrested for it.
Nightblood[]
- Main article: Nightblood
Radiation Immunity
"Nightblood", originally called "Black Blood", is an experimental serum created by Becca Franko. It is also referred to as "Blood Alteration" or "Radiation Immunity".
In general, having Nightblood enables a person to recover from radiation poisoning. In "The Four Horsemen," though Luna got sick with Acute Radiation Syndrome, a form of radiation poisoning, her Nightblood enabled her to recover on her own. In "The Chosen," Clarke Griffin similarly got sick, but eventually recovered due to her own Nightblood. In "False Gods," both John Murphy and Emori suffered radiation poisoning from fixing a melting down nuclear reactor to the point that it was lethal to four Eligius prisoners without Nightblood. In "Welcome to Bardo," both recover due to their Nightblood with the help of medical treatment from Doctor Eric Jackson though Emori takes longer.
As seen in "Anaconda," injecting a person with Nightblood is an effective treatment to radiation poisoning. Even if the case is terminal, being given Nightblood allows the person to recover from the effects.
Tree Sap[]
After a Temporal Flare, the sap in the remains of fossilized trees becomes "mutated". When applied to the skin, it causes a time dilation effect – wounds heal faster, but it causes accelerated aging (caused by exposure to a Temporal Flare). Gabriel Santiago called the bottled sap, "Time in a Bottle."
In "Etherea," Bellamy treats Conductor Doucette's broken leg with tree sap, explaining that Charles Pike had taught him that oozing sap from pine trees on Earth can be used to create antiseptic, fight infection and heal wounds. Bellamy expresses hope that the same goes for the trees on Etherea which proves to be the case as Doucette ultimately recovers.
Sedative[]
Referred to by Eric Jackson as a "reaper stick" is a sedative used by the Sky People to sedate an individual.
Anti-Toxin[]
- Main article: Anti-Toxin
Bellamy uses an Anti-Toxin inhaler.
The Anti-Toxin was created by Gabriel Santiago in case of the Red Sun toxin. The first step in creating it is to steam distill the actual toxin into a supersaturated solution 3 grams per milliliter to start.
In "Ashes to Ashes," Bellamy and Octavia Blake use the anti-toxin in order to protect themselves as they collect plants with the Red Sun toxin for their plan to defeat the Primes.
In "Adjustment Protocol," both the Primes and the Children of Gabriel use the anti-toxin when Russell Lightbourne releases a Red Sun toxin bomb into a crowd of Sanctumites.
In "Blood Giant," after another Red Sun eclipse starts, Clarke retrieves anti-toxin from the farmhouse while getting the Flame and she gives it to Bill Cadogan, the Disciples, Bellamy Blake, Raven Reyes, John Murphy and the people in hiding in the nuclear reactor. At the same time, Gabriel heads to the lab to get the anti-toxin, but discovers that there is only one dose left due to the Primes using it to escape to space. Hallucinating Josephine Lightbourne, Gabriel gives the single dose to Eric Jackson and walks him through creating more using the ingredients in the lab. After reaching Indra, Jackson gives her some, ending her hallucinations of her mother. Subsequently, Gabriel decides to take the anti-toxin himself after deciding to destroy the Flame instead of repairing it, causing Josephine to vanish.
