A little knowledge about Gastrodia elata: Gastrodia elata was first recorded in Shennong Materia Medica Classic, named "Red Arrow". Why was it later called Gastrodia elata? First, gastrodia elata has no roots and leaves and no chlorophyll, so it can't carry out photosynthesis. Sow according to ordinary crops, and there will be no harvest in the second year. The ancients thought: Gastrodia elata grows magically. If it is given by heaven and equipped by heaven, that is its shape. In ancient times, hemp was used as its shoe, hence the name Tianma. Secondly, the seeds of gastrodia elata are very small, which is difficult to distinguish with the naked eye, so the ancients said that "mortals can't grow" and found gastrodia elata, which is considered a godsend. So it is called "Gastrodia elata".
In the 1960s, gastrodia elata was planted in a Miao family in Zhenxiong County, Yunnan Province, and it grew well. Finally, the reason is that there are many stumps and high humidity. After exploration, it was found that Gastrodia elata could decompose and absorb bacteria from beginning to end, and was later identified as Armillaria mellea. Gastrodia elata is inseparable from Armillaria mellea, but Armillaria mellea can still rot on litter or parasitize on other plants without Gastrodia elata. This established that Tianma lived by "what to eat"
The mystery of the dragon, by 1970, artificial asexual propagation was successfully cultivated. Gastrodia elata seeds can't germinate because there is no external nutrition supply. They can only germinate after being infected by Pleurotus ostreatus and other biological bacteria and establishing a nutritional relationship to form protocorms. Therefore, only a few of the commercial gastrodia elata are wild, and most of them are artificially cultivated. The appearance of the two is different. Wild gastrodia elata varies in size and slightly shorter in shape, while the planted gastrodia elata is even in size, slightly larger, oblate and strip-like. The efficacy of the two should be the same.
At present, there are still fake gastrodia elata in the farmer's market, and its varieties are mainly purple jasmine and potatoes. Pay attention to identification when buying. But as long as we know the genuine gastrodia elata, it is easy to identify the fake gastrodia elata.
