The knowledge they invited from experts is true, but the so-called expert consultation telephone should not be called. Chinese medicine says that a phone call can help you see a doctor, which is definitely not reliable. Look at the recruitment marketing and telephone customer service on the website of Yangshengtang Company for many years, and you will know that the purpose is to sell medicine. My family has been fooled, and the phone keeps calling every day, lobbying you to buy again. But this medicine doesn't work at all. In addition, this medicine has been ground into powder by several common drugs. You don't know the color and it's not worth the price. It is useless at all, but it increases the burden on the patient's stomach and delays the illness. We regret it now.
