Rhizoma gastrodiae is a Chinese herb.



Gastrodia elata, also known as Tian Ma in Pinyin, can be traditionally used as a Chinese herb for the treatment of headaches, dizziness, numbness, convulsions in children, epilepsy, tetanus, hemiplegia, neurasthenia, angioneurotic headache, cerebral arteriosclerosis, senile dementia, sudden deafness, central retinitis, cervical spondylosis, Meniere’s syndrome, and so on. The main medicinal part is its root.


The medicinal uses of gastrodia elata are characterized by calming liver wind agitation by suppressing hyperactive liver and calming hyperactivity of liver-yang by tranquilizing liver and yang. However, other herbs like Cat’s Claw (Gou Teng) and Antelope Horns (Ling Yang Jiao) are also capable of what it does. So, what are the distinct health benefits of gastrodia? Actually, Cat’s Claw is of cool, light, and penetrating nature, which makes more sense in treating mild convulsions and fever in children since it is good at clearing heat for calming endogenous wind; Antelope Horns have a more powerful heat-clearing properties since it is of cold nature. In addition to be used in treating extreme heat causing wind, it cures also coma due to high fever, spots caused by heat toxicity, etc. since it is able to clear away the heart-fire and detoxify; gastrodia is of sweet, neutral, and moist nature. It has less ability on clearing heat than Cat’s Claw and Antelope Horns. Its strength is the versatility of any types of up-stirring of the liver and epileptic seizures, regardless of the patterns are of cold, heat, deficiency or excess nature. What’s more, it can relieve mind to bring headache relief.

Now it is time to talk about luminous fungi called Armillaria mellea Fr., which is the nutrient source of gastrodia seeds and tubers. Studies have shown that the solid culture of Armillaria has similar pharmacological effects and clinical efficacy of gastrodia. For the reason, now the medicinal preparations of Armillaria mellea Fr. are mostly replaced Tianma to treat dizziness, headache, insomnia, hemiplegia, numbness, and so on.
