Slightly Cold Sweet StomachKidney

“An orchid that grows on rock and sells like jewelry — emperors hoarded it, counterfeiters imitate it, and all it ever claimed to do was put moisture back where illness spent it.” — Lao Xinglin

What the tradition says

Shi hu — "bushel of stone" — is the stem of an orchid that clings to cliffs, and the tradition ranked it among its treasures: the premier restorer of stomach fluids and yin, for the parched mouth and thirst after fever, the dry heaves of a depleted stomach, and the dim eyes and weak back of long decline^[1]. The old materia medica listed it in the top grade — the herbs for cultivating life, not just curing disease — which partly explains the imperial prices it still commands.

What the research says

A large laboratory literature and a thin clinical one: reviews catalog its polysaccharides and alkaloids with antioxidant and blood-sugar-related activity in lab and animal work^[2] — consistent with the moistening, fluid-restoring folk role, and unproven in people. The price of the fancy grades is set by scarcity and ceremony, not by trial data; this cabinet says so out loud.

Where to be careful

A gentle drawer: avoid mainly in early, hot infections (the tradition worries it "locks the thief indoors") and in cold-damp constitutions that need drying, not moistening^[1]. The practical hazard is commercial: shi hu is among the most faked items in the trade — dyed lookalike stems abound. Buy from serious pharmacies or not at all.

In the pharmacy

Golden-green jointed stems, often wound while fresh into little springs ("iron-skin maofeng" spirals command the top prices), or sold as feng dou coils for chewing and steeping. In the kitchen it simmers with mai men dong into the classic fluids-restoring drink, or joins Xing Po's lean-pork soups for the recently recovered. The hair-and-skin room mentions its court history — the empresses drank their orchids; the trials remain unrun.
