She Mei (蛇莓; Shé Méi; Latin: Duchesneae Indicae Herba; English: indian strawberry herb) in the current pharmacopoeia is the dried or fresh whole plant of Duchesnea indica of the Rosaceae family — a slender creeping herb with yellow flowers and small red berry-like fruits, harvestable all year, with the summer flowering-fruiting period holding the more concentrated effects, usually washed, cut, and dried for raw use. It is cold, sweet, and bitter, enters the Lung, Liver, and Large Intestine channels, and its core actions are to clear and resolve heat toxin, and to astringe the skin and stop itching. It usually goes into light cooling teas, or is decocted for external washing. The usual amount is 10–15 g by mouth in a decoction; dried slices soak ten minutes first, then simmer ten to fifteen minutes, with no pre-decocting or late addition needed. External use is a suitable amount — 30–60 g decocted, cooled to warm, and washed over the itchy or mildly burnt spot.
It is not Di Jin Cao. Di Jin Cao (Spotted Euphorbia Herb) is bitter-acrid and heavier cold, leaning to cooling blood and stopping bleeding for bloody stool and blood in the urine; this indian strawberry is a milder cold that leans to astringing the skin and stopping itching. Spleen-stomach deficiency-cold, with cold limbs and loose stool, is a poor match. Broken, discharging sores should not be washed with it on your own. Swelling after snake encounters needs emergency care first. Anyone allergic to Rosaceae plants should skip it. Do not brew it daily for more than a few days.
It is used most often for three patterns:
-
Heat-toxin sores — small red, swollen, painful skin sores, mild sore throat, dry mouth, yellow urine
- Damp-heat skin itching — eczema rashes, stubborn itch, mild local swelling after insect irritation
-
Minor burns and scalds — mild local redness without broken skin
Cold, sweet, and bitter, it is not a daily “cooling grass tea” to keep brewing. Cold herbs with no heat toxin present chill a weak stomach and bring loose stool.
When heat toxin gathers on the body surface, or damp-heat steams the skin, red sores, itching rashes, and mild throat swelling are common. She Mei is cold, sweet, and bitter. It clears and resolves heat toxin, astringes, and stops itching, which is why it appears in She Mei Jian (Indian Strawberry Decoction)–type formulas. It clears the surface more than it enters deep. A deficiency-cold spleen and stomach, with loose stool and no heat toxin, get worse if more is added.
She Mei is not a catch-all cooling herb for every skin mark. In deficiency-cold, with no heat toxin, or on broken, discharging skin, using it alone is a poor match. Fresh or dried, and whether it belongs in a formula, should be decided by a licensed Chinese medicine practitioner after pattern diagnosis.
