However, these plants and trees either exist as weeds or are unfamiliar to most people. Even if they are familiar with it, they don't know that their drug prices are as common as morning glory in rural areas. Its seeds are traditional Chinese medicine black, ugly, white and ugly. Morning glory is very common in rural roadside or farmland. As a weed, it will entangle and interfere with crops, and people in the field will be eliminated like weeds.
Just like dandelion leaves change a lot, many people can easily admit their mistakes, let alone pick them to make herbs. Bufo grass is also unknown to many people. Quality problems Although there are many traditional Chinese medicines in rural areas, most of them are wild like this. Growth and soil conditions are different, so their quality is also very different. The most common Lycium barbarum berry in rural areas is China Lycium barbarum variety. Compared with Ningxia Lycium barbarum, which is commonly used in traditional Chinese medicine, they are small in size and relatively low in sugar content.
Moreover, its growth conditions are not as good as real medicinal materials, and its natural quality is even worse. Like wild rehmannia, it is much better on the roadside and beside ditches. Year after year, it blooms and falls from the fruit, and underground tubers are used as medicine. However, the roots of most wild Rehmannia glutinosa are not very large, and their quality cannot be guaranteed. Picking problems Many weeds are herbs, but due to distribution problems, picking is also very laborious. Just like the common cruciferous weeds that make vegetables. Its seed is a famous Chinese medicine, Tinglizi, which is too laborious to pick. First, you must mow the grass to disperse the seeds and dry them before you buy them.
All over the world, they don't buy many things, and the purchase price is not high, one to two yuan per catty, which takes a lot of people and labor, and it is best to go out to work to earn more money. The yield problem is that all the herbs in the countryside are scattered. They are not as concentrated as cultivated or authentic herbs. The growth conditions are also great, and the yield is naturally not too high. Although there are many wild Rehmannia glutinosa along the road, it may not be found in actual excavation. The vegetable Beiting Lizi, a lonely tricycle, also dried 20 or 30 Jin of seeds, and the yield was too small. It can be seen that the wild medicinal materials in rural areas are either unfamiliar to people, or they don't know the price of drugs, or they are familiar with them, with low output, poor quality and high labor intensity. Naturally, many people are familiar with it and will not choose it.
