Toxicology
Toxicology studies harmful substances, their mechanisms of action, dangerous doses and antidotes. In The Apothecary Diaries it is everywhere: lead-based face powder, mercury, aconite, pufferfish, mushrooms. Maomao excels at it to the point of testing poisons on herself.
Entries in this discipline
Aconite
In The Apothecary Diaries, aconite poisons even through honey. We explain aconitine, its action on nerves, and why it shows no mercy.
Amaryllis
Only after long soaking, and never risk-free: lycorine causes vomiting and cramps. Why soaking is not enough, and the warning in The Apothecary Diaries.
Datura
In The Apothecary Diaries, datura is used to induce sleep and feign death. We explain its alkaloids, its toxicity, and its role in the history of anesthesia.
Elixirs of Immortality
Cinnabar, mercury, arsenic: Chinese waidan alchemy sought eternal life in poisons. The alchemists' logic, what mercury does to the brain, and who died of it.
Fake Death by Tetrodotoxin
Partly: pufferfish poison can paralyze a person until they look dead, brain still awake. Datura agitates instead of sedating. Mechanisms, real cases, limits.
Four O'Clock Flower
Partly: four o'clock flower seeds hold a protein that ends pregnancy in mice, never tested in women. Mechanism, toxicity and the limits of court lore.
Fugu and Tetrodotoxin
In The Apothecary Diaries, Maomao loves fugu and its poison. We explain tetrodotoxin, how it paralyzes, and why there's no antidote.
Frog Skin
Frog skin is both a respiratory organ and a chemical arsenal. Protective mucus, bufotoxins, batrachotoxin, and chan su in traditional medicine.
Fungal Bioluminescence
In The Apothecary Diaries, a glowing mushroom is mistaken for a chanterelle. We explain fungal bioluminescence and this dangerous mix-up.
Induced Vomiting
Making someone vomit to clear a poison: an old intuition that modern medicine has largely abandoned. Risks, contraindications, the history of ipecac.
Lead White Makeup
Ceruse is lead carbonate: worn daily, it caused slow lead poisoning. The symptoms, why it killed nursing infants, and the palace curse in The Apothecary Diaries.
Mercury
In The Apothecary Diaries, quicksilver goes into a court poison. We explain mercury, its toxicity, and the immortality elixirs that killed emperors.
Nicotine and Tobacco
In The Apothecary Diaries, macerated tobacco serves as a poison. We explain nicotine, its acute toxicity, and why diluting a poison can make it worse.
Orpiment and Arsenic
In The Apothecary Diaries, a yellow pigment poisons slowly. We explain orpiment, arsenic, and the chronic poisoning of court painters.
Rhododendron and Mad Honey
In The Apothecary Diaries, a tainted honey and a burned plant cause poisoning. We explain rhododendron's grayanotoxins and the famous mad honey.
Sensory Detection of Poison
Rarely: arsenic and tetrodotoxin have no smell or color. What imperial food tasters could catch, why silver failed, and what The Apothecary Diaries gets right.
Saxitoxin and Toxic Shellfish
Microalgae make saxitoxin and mussels store it: it blocks nerve signals, with no antidote. Red tides, the fugu comparison, and the case in The Apothecary Diaries.
