Gastrodia elata extract is a brownish-yellow
fine powdery substance extracted from the dried tubers of the
orchid Gastrodia elata Blume. Gastrodia elata is a parasitic plant,
and its host is Ringworm. 'Spring hemp' is excavated between April
and May in spring;
'winter hemp' is excavated between September and October before the beginning of winter, and the quality is better. After digging up, wash off the soil while it is fresh, soak it in water or alum water, scrape off the outer skin, boil or steam through the heart, slice it, and spread it out to dry.
