The Belladonna (天仙子) Poisoning

Lore & Background

天仙子, known in the Western pharmacopoeia as henbane (Hyoscyamus niger), is a plant long used in traditional medicine for its analgesic and antispasmodic properties. In the small, carefully measured doses of a licensed herbalist it eases pain and calms tremors; in the wrong hands—or the wrong dose—it becomes a paralytic, hallucinogenic, potentially fatal agent. Its tropane alkaloids (hyoscyamine, scopolamine, and atropine) block muscarinic acetylcholine receptors, producing the classic anticholinergic toxidrome: parched mouth, flushed and dilated pupils, racing heart, confusion, and vivid hallucinations that can progress to convulsions and respiratory failure.

In the world of the harem, where every bowl of broth and every herbal paste passes through the hands of attendants, physicians, and rivals, a single substitution of a therapeutic herb with its toxic cousin can look exactly like a relapse of a chronic ailment. This is precisely the trap set in the 天仙子 case: the victim's symptoms mirror a known condition, and the attending physicians are led to believe the illness is natural. Only Maomao, who has spent her youth making poisons before she was captured and repurposed as a healer, recognizes the tell-tale combination of dry membranes, mydriasis, and the particular quality of the delirium that no natural disease produces.

The political fallout is as important as the medical one. The harem operates on a fragile hierarchy of favor, and a poisoning—especially one that nearly kills a woman of standing—threatens to unravel alliances. Maomao's identification of the culprit forces the emperor's household to confront how easily trust is weaponized among those who serve at his table, and it cements her reputation as someone who sees what others are trained not to see.

Presenting symptom: A harem resident, previously stable, suddenly deteriorates with confusion, a parched and burning throat, flushed dry skin, and a racing pulse. The attending physicians note the resemblance to a known respiratory ailment and prepare to treat it as a relapse. Maomao's diagnostic reasoning: She is summoned and immediately notes what the others missed—the pupils are widely dilated and unresponsive to light, the mouth and mucous membranes are bone-dry, and the patient's delirium has a particular quality: the woman is not merely confused but seeing and hearing things that are not there, with a glassy, detached stare.

No natural cough or lung disease produces mydriasis plus xerostomia plus visual hallucinations in that combination. Maomao cross-references the symptom cluster against the tropane-alkaloid toxidrome and identifies 天仙子 as the likely agent. True cause: A deliberate poisoning. Someone with access to the victim's medicinal preparations substituted or spiked a standard herbal decoction with a concentrated preparation of henbane, calibrated to look like a worsening of the existing condition.

The motive is rooted in harem politics: eliminating or incapacitating a rival to shift the emperor's favor. Resolution and political fallout: Maomao administers an anticholinergic-antagonist regimen and supportive care, stabilizing the victim within hours. She then traces the source of the 天仙子 preparation through the harem's apothecary stores and identifies the hand that dispensed it. The perpetrator is exposed, and the case forces a review of who has access to the inner medicine stores.

The harem's power dynamics shift: the victim's faction gains leverage, the perpetrator's allies are quietly reassigned, and Maomao's standing as an indispensable diagnostician is further secured—though she remains, as always, a woman who would rather be left alone with her herbs and her silence.
