Gastrodia elata

Gastrodia elata is a saprophytic perennial herb in the Orchidaceae family. It is found in Nepal, Bhutan, India, Japan, North Korea, Siberia, Taiwan, and China. The herb is used in traditional Chinese medicine and Sichuan cuisine. It is one of the three orchids listed in the earliest known Chinese Materia Medica (Shennon bencaojing) (c. 100 AD). Medicinally, it is used for 'calming the liver' and for treating headaches, dizziness, tetanus, and epilepsy. According to 'Nutrition Review,' 'Gastrodia root has been shown to exert novel pain relief and inflammatory-mediating activities, as well as in vivo and in vitro inhibitory activity on nitric oxide (NO) production.'
