Orchidaceae · rhizome
Gastrodia
Gastrodia elata
Rhizome mapped as Tian Ma: extinguishes wind and settles Yang in Liver Yang Rising formulas such as Tian Ma Gou Teng Yin.
Safety first
Conservation/orchid identity. Not a stroke protocol. Thunderclap headache, focal neuro deficit, and hypertensive emergency stay medical. Gastrodin extracts are a modern object.
Tradition vs trials
Traditional record. Bensky: Tian Ma calms the Liver, extinguishes wind, and stops spasm in classical language.
Trial literature. Gastrodin has modern Chinese research; this catalog still tags the pattern mapping traditional.
