Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Gastrodia elata, known as "Tian Ma" in traditional Chinese medicine (TCM), is primarily used for conditions related to wind, such as dizziness, headaches, and convulsions, rather than directly for dysmenorrhea (painful menstruation). However, in some traditional herbal formulas addressing gynecological issues, Gastrodia is occasionally included for its reputed ability to "calm the liver" and relieve pain. The rationale is based on TCM theory: dysmenorrhea may be associated with liver qi stagnation or internal wind, and Gastrodia is believed to pacify internal wind and promote smooth flow of qi. There is limited direct historical documentation of Gastrodia as a standalone remedy for menstrual pain, but it can be found in some compound prescriptions such as those targeting headaches or spasmodic pain, which are sometimes extended to dysmenorrhea.

As for scientific evidence, research on Gastrodia's effects mostly focuses on its neuroprotective, anticonvulsant, and anti-inflammatory properties. A few animal studies suggest that Gastrodia extracts have analgesic and anti-inflammatory actions, which could theoretically benefit dysmenorrhea; however, no robust clinical trials specifically validate its use for menstrual pain in humans. Therefore, the traditional use is present but not widespread, and the scientific support is weak at present, meriting a low evidence rating.
