Belladonna
A berry that opens the eyes of the living and the hands of the dead.
In the pharmacopoeia of the Imperial Palace's apothecary, Belladonna (颠茄, diānqié) occupies one of the most treacherous shelves: a plant whose leaves, berries, and roots carry tropane alkaloids capable of halting a heartbeat or, in minute and carefully measured doses, easing the spasm of a constricted pupil. For Maomao, whose entire life has been a conversation with poisons and remedies, Belladonna is neither villain nor savior but a tool that demands the same reverence as a blade—useless in the wrong hand, lethal in the careless one, and quietly indispensable in the surgeon's kit.
As a substance it sits at the intersection of the story's central tension: the line between medicine and murder is drawn not by the ingredient but by the intention, the dose, and the knowledge of the hand that grinds it. In the gilded corridors of the palace, where courtiers smile over tea and servants kneel in the dust, a single crushed berry slipped into a cup of wine can mimic the symptoms of a hundred other ailments, making it a favorite of those who wish to poison without leaving a trace that a less learned examiner would catch.

Lore & Background
Belladonna is a perennial herb of the nightshade family, native to dry, well-drained soils and shaded hedgerows. Every part of the plant—leaves, stems, roots, and especially the small black-purple berries—accumulates tropane alkaloids, with the highest concentrations in the root and the unripe fruit. In the pharmacological tradition that Maomao inherits, the plant is prepared as a tincture, a dried leaf poultice, or a finely powdered extract, and its anticholinergic action (blocking acetylcholine at muscarinic receptors) makes it useful for dilating pupils in ophthalmic work, reducing bronchial spasm, and easing the painful cramping of the gut.
The same action, at ten or twenty times the therapeutic dose, produces the classic anticholinergic toxidrome: dry as a bone, blind as a bat, red as a beet, mad as a hatter, hot as a hare—then, if the dose is high enough, cardiac arrhythmia, respiratory failure, and death. What makes Belladonna particularly insidious in a court setting is its pharmacological mimicry. At sub-lethal doses its symptoms—tachycardia, dry mouth, dilated pupils, confusion, hallucination—can be mistaken for heatstroke, a mild stroke, or even a psychogenic episode.
A court physician who does not think to test for anticholinergic agents may miss it entirely. Maomao's training, which includes the practical discipline of recognizing alkaloid profiles by taste, smell, and the pattern of the patient's symptoms, is what allows her to distinguish a Belladonna poisoning from the dozens of other substances that produce overlapping signs. Its presence in the apothecary is a constant reminder that the same shelf that cures also kills, and that the person who knows which is which holds more power than any eunuch or concubine in the inner court.
Reader's Guide
In-world name: 颠茄 (diānqié), also referenced in broader pharmacopoeia texts as a nightshade-family toxic. Botanical origin: Atropa belladonna, a perennial of the Solanaceae family; in the story's setting it is cultivated or foraged from dry, shaded ground and processed in the palace apothecary's drying racks. Preparation and concealment: the active tropane alkaloids are extracted as a tincture (alcohol-based), a dried-leaf decoction, or a fine powder; the small dark berries can be concealed in food or drink because their flavor is mild and their symptoms at low dose are easily misattributed.
Symptom timeline: onset within 30 minutes to 2 hours of oral ingestion—dry mouth, blurred vision, dilated pupils, tachycardia, flushing; peak at 2–6 hours with confusion, hallucinations, hyperthermia, urinary retention; at lethal doses (roughly 10× therapeutic), ventricular arrhythmia, respiratory paralysis, and death within 6–12 hours if untreated. Antidote/treatment: Maomao's approach centers on physostigmine (an acetylcholinesterase inhibitor) to reverse the anticholinergic block, combined with aggressive supportive care—cooling, IV fluids, cardiac monitoring.
In the story's medical tradition she may also employ supportive herbal adjuncts to protect the liver and reduce secondary inflammation. Recurring vs. one-off: Belladonna functions as part of the broader toxicological toolkit Maomao draws on across multiple investigations rather than being tied to a single named arc; it is a recurring reference point in her pharmacological reasoning.
