Wolfsbane

Lore & Background

In the pharmacological tradition that underpins the palace's medical practice, Wolfsbane occupies a paradoxical position. In minute, carefully prepared doses—decocted for long periods, combined with warming agents—it has been used to drive out deep cold from the joints and to stimulate a sluggish circulation. In the hands of a careless or malicious preparer, however, the same root delivers aconitine in a concentration that overwhelms the heart's electrical rhythm and seizes the respiratory muscles. This duality makes it a favourite of the palace's hidden politics: a poison that mimics a sudden illness, that leaves no obvious residue in the stomach, and that can be slipped into a shared cup of wine without altering its colour.

Maomao's particular expertise lies in the olfactory and gustatory signatures that betray aconitine. The characteristic tingling on the tongue and lips, the metallic bitterness that lingers like cold iron, the way the victim's pupils dilate before the first arrhythmia—these are the markers she reads the way a scholar reads a text. She has learned, through years of cataloguing the palace's herb stores, that Wolfsbane is often stored alongside other bitter roots, and that a single misplaced root in a communal drying rack can contaminate an entire batch of what was meant to be a harmless digestive tonic.

The political weight of a Wolfsbane poisoning in the palace is enormous. Because the toxin acts so quickly, the victim often dies before a physician can be summoned, and because the residue is water-soluble and volatile, a thorough washing of the vessel can erase all trace. This makes Maomao's ability to reconstruct the timeline from the victim's remaining symptoms—rather than from a post-mortem residue test—critically important. In several of her investigations, it is her insistence on re-examining the victim's lips, the inside of the cup, and the order in which the symptoms appeared that unravels a conspiracy that would otherwise have been written off as a sudden stroke or a fit of the wind.

In Their Own Story

The candle in Lady Rui's private study had burned to a stub when Maomao finally arrived, her sleeves rolled to the elbow, a small vial of activated charcoal clutched in one hand. The woman sat slumped in her chair, lips blue-tinged at the edges, a half-finished cup of plum wine still warm on the table beside her. The steward had called it a seizure. The attendant had called it a stroke.

Maomao did not call it either. She leaned close, pressed two fingers to the woman's wrist, and felt the arrhythmia stutter like a skipping drum. Then she tilted the cup, breathed in. Bitter. Cold. The unmistakable ghost of aconitine clinging to the wine's sweetness.

"She didn't seize," Maomao said, her voice flat and professional, the same voice she used when cataloguing a new shipment of dried roots. "She was poisoned. And whoever poured that wine knew exactly how much to use—enough to stop the heart before the physicians could reach this room." She uncorked the vial. "I need the woman's lips swabbed, the cup sealed, and every other guest in this hall brought to me for tasting. Starting with the one who poured."

Reader's Guide

In-world name: Wolfsbane (Aconitum); in the palace's herbal index it is filed among the bitter cold-purging roots. Botanical origin: the tuberous root and lower stem of the Aconitum plant, a hardy perennial that grows in damp, shaded ground. The active principle, aconitine, is a diterpene alkaloid that binds sodium channels in cardiac and nerve tissue, keeping them perpetually open and triggering uncontrolled depolarisation.

Preparation and concealment: In the palace's context, the root is most often ground to a fine powder and stirred into a liquid—wine, broth, or a multi-herb decoction—where its bitterness is masked by sugar, fruit, or the strong flavours of other spices. Because aconitine is water-soluble, it does not leave a visible residue in the vessel, and a quick rinse with hot water removes most of the detectable trace. A skilled poisoner need only use a fraction of a gram to be lethal.

Symptom timeline: Onset typically begins within 10–30 minutes of ingestion. The first sign is a tingling or numbness of the lips, tongue, and fingertips, followed by a metallic bitterness in the throat. Within 30–60 minutes, the victim experiences dizziness, blurred vision, a pounding or irregular heartbeat, and progressive muscle weakness. Peak toxicity arrives as ventricular arrhythmia, respiratory paralysis, and loss of consciousness. Without intervention, death from cardiac arrest or asphyxia can occur within one to two hours.

Treatment Maomao devises: Her first priority is to stop further absorption—inducing vomiting if the victim is still conscious, or administering a binding agent (activated charcoal, a starch slurry, or a tannin-rich decoction) to sequester residual aconitine in the gut. She then addresses the cardiac instability with a carefully dosed warming and stabilising preparation drawn from the palace's stores, combined with aggressive stimulation of respiration. In severe cases, she relies on the victim's own reflexes, keeping the airway clear and applying external warmth to maintain circulation until the toxin is metabolised. She is candid that the window is narrow: once the heart's rhythm has fully deranged, no herbal preparation can restore it.

Recurring status: Wolfsbane and its aconitine family appear as a recurring class of botanical toxin across multiple palace cases, reflecting the series' broader pattern of drawing on real pharmacological knowledge. It is not confined to a single arc but represents the ever-present threat of the palace's own herb stores being turned into weapons.
