Where can I buy Qingfei Jiedu Soup? Seeking popular science

I come from Guangxi and have heard of this medicine. Qingfei Paidu Decoction comes from the combination of classic prescriptions of traditional Chinese medicine, including Maxing Shigan Decoction, Shegan Mahuang Decoction, Xiaochaihu Decoction and Wuling Powder, which is mild in nature and taste. At present, it is listed as the first choice in clinical treatment of traditional Chinese medicine, suitable for mild, moderate and severe patients, and can be used reasonably according to the patient's situation in the treatment of critically ill patients. Qingfei Paidu Decoction has played an important role in the anti-epidemic battlefield, and the clinical proof shows that the total effective rate is over 90%.
