Scutellaria (Huang qin)

Modern sources record use restrictions for Scutellaria baicalensis root (huang qin). The WHO monograph on Radix Scutellariae states that, owing to possible teratogenic and mutagenic effects and a lack of safety data, its use is contraindicated during pregnancy and nursing and in children under 12 years of age; the monograph also notes that, although liver damage from the root has been suggested, no direct correlation to any published cases of liver damage has been established. This is reference information drawn from modern sources, not a diagnostic or treatment recommendation.
