Who is suitable for taking Gastrodia elata?

As a traditional Chinese medicinal material, Gastrodia elata is mainly suitable for people with headaches, dizziness, numbness of limbs, and neurasthenia. Modern research shows that its active ingredient gastrodin has a regulatory effect on the central nervous system, but it needs to be used according to physical syndrome differentiation. The following is an explanation from the three dimensions of applicable groups, contraindications and product selection.

Clinical studies have shown (Chinese Journal of Traditional Chinese Medicine, 2020) that Gastrodia elata has a significant effect on patients with hypertension due to excessive liver yang. Symptoms such as flushed face and ears, and irritability are common in this group of people. The ancient Yi medical book "Qi Gu Shu" from Yunnan records that Gastrodia elata combined with Uncaria can enhance the effect of calming the liver and calming wind. However, people with yin deficiency constitution (shown as hot flashes and night sweats) should not use Gastrodia elata alone.

Common products currently on the market include Kunming Pharmaceutical Factory's "Gastrodin Tablets" and Tong Ren Tang's "Gastrodia Uncaria Granules", etc. Each gastrodin tablet contains 25 mg of gastrodin, and it should be noted that the daily dose does not exceed 100 mg. The Chinese Pharmacopoeia stipulates that high-quality gastrodia elata should be translucent and have a "parrot's beak" cross-section. You need to identify the authenticity when purchasing.

In summary, Gastrodia elata is suitable for people with specific physical constitutions to use under the guidance of a physician. It is recommended that first-time users start with a small dose and observe whether adverse reactions such as dry mouth and heart palpitations occur. Modern pharmacology has confirmed its high safety (Journal of Ethnopharmacology, 2021), but it should not be taken together with central nervous system depressants. When purchasing, be sure to look for products with approved brand names and avoid purchasing products with “three noes”.
