2. Some medical units used synthetic gastrodin to treat neurasthenia and neurasthenia syndrome, and the effective rates were 89.44% and 86.87% respectively. It can also inhibit the central excitement caused by caffeine and enhance the sleep time effect of pentobarbital sodium.
3. Gastrodin contained in Gastrodia elata can inhibit the central nervous system in the body and play a calming role.
Gastrodia elata also has the function of lowering blood pressure. Gastrodia elata can dilate blood vessels, increase the permeability of blood vessels, reduce the viscosity of blood, and increase the blood flow of peripheral arteries and coronary arteries.

Extended data:
1. Gastrodia elata is suitable for growing in an environment that is cool in summer and not too cold in winter. The central and southwestern regions of China are mostly distributed in the alpine mountainous areas with an altitude of 1300 ~ 1900 meters. Due to the high latitude and low temperature in Northeast China, Gastrodia elata is mostly distributed in low mountainous areas or hilly areas with an altitude of 200 ~ 700 meters. When the ground temperature was above 10 ~ 12℃, gastrodia elata began to sprout and grow. When it reaches 15℃, the growth of gastrodia elata will gradually flourish.
2. Gastrodia elata usually grows vigorously from late May to early September, when the ground temperature is 20 ~ 25 degrees Celsius. However, when the soil temperature exceeds 30 degrees Celsius, the growth of Armillaria mellea and Gastrodia elata is inhibited. When the temperature is lower than 15℃, the growth slows down rapidly, and with the temperature falling again, the growth gradually stagnates and enters the hibernation period. The annual rainfall in the producing area is above 1000 mm.
3, the average relative temperature is about 80%, rainy and humid climate conditions. It is most suitable for the growth of gastrodia elata.
