There are many Shenshitong granules produced by different manufacturers. Which is better?

I don't think so. This Sanjiu brand was hung by a manufacturer in Hunan. As for whether their production technology and raw materials are really like 39, it is not necessarily so.

I looked at it and it was revised by Jilin. If I buy it, I might choose this manufacturer.

Other manufacturers are: Guangdong Zai Tian Pharmaceutical, Jiulianshan Pharmaceutical, Hebei Wansui Pharmaceutical, Guangdong Shenwei Pharmaceutical, Liaoning Jindan Pharmaceutical, Heilongjiang Huaxing Pharmaceutical, Chengde Tianyuan Pharmaceutical, Hunan Sanjin Pharmaceutical, Lanzhou Heshengtang, Guangzhou Ye Huan Pharmaceutical, Shenyang Yitian Pharmaceutical, Harbin Tang Shiyi, Zhangshu Pharmaceutical, Nanjing Housheng Pharmaceutical, Luo Shangshan Pharmaceutical, Jilin Ji Chun Pharmaceutical, Anshan Pharmaceutical Company and Jiangxi Zhongxing.

Buy it yourself.
