Apocynum tea, a rare treasure in the desert, has the functions of lowering blood pressure, calming the liver and calming the nerves, and relieving cough and asthma. Apocynum tea is a natural tea beverage made of wild apocynum venetum leaves, which is scientifically and precisely processed according to the nourishing theory of traditional Chinese medicine. It conforms to the new world consumption concept of keeping healthy, green, low-carbon and healthy. I suggest you find the right place to buy it, so that you can buy something with better quality. I bought it at the flagship store of desert treasure on Taobao. They are brand direct sales, and the price is more affordable.
