Da Dou Huang Juan大豆黄卷
Sojae Semen Germinatum · Germinated Soybean · Dried Soybean Sprout
Overview
· Disperse Wind-Heat — to Dan Dou Chi 淡豆豉. Da Dou Huang Juan is the black soybean sprouted until the shoot is about a centimetre long, then dried. Sweet and neutral, it is the mildest herb in the chapter: it lifts a summerheat-damp or early damp-warm pattern outward while quietly draining damp, which suits the picture of low fever that will not break, scant sweating, a stuffy chest and a greasy tongue coat. It is a food-grade herb and is chosen for its gentleness — it is never the herb that will force a strong exterior pattern open on its own.

Cautions
No recorded toxicity — this is a food-grade herb. Two practical points: it is made from soybean, so it is avoided in anyone with a soy allergy; and it is mild, so it should not be relied on alone to break a strong exterior pattern or a high fever. Those with cold and weakness of the Spleen and Stomach may find it slightly cooling in larger amounts.
Contraindicated in pregnancy: Generally compatible with pregnancy — a mild, food-grade herb with no traditional restriction. Practitioner judgment still applies, and soy allergy is the relevant exclusion.
