Do you know the efficacy of purple ginseng?

Purple ginseng is interpreted as Meng Mu, Tongchang, Maxing, Zhong Rong and Wuniaohua. The smell (root) is bitter, cold and nontoxic. Indications 1, diarrhea. Use half a catty of purple, add five liters of water and fry it into two liters. Add licorice, fry until half a liter, and take it three times. This prescription is called "Zishen Decoction". 2, vomiting blood. Parching Ginseng Radix, Ginseng Radix and Colla Corii Asini, and pulverizing into powder. Every time you pay a sum of money, you will get a piece of ebony soup. You Fang: It's basically the same as above, except for ginseng.

Mixing Ginseng Radix, Saviae Miltiorrhizae Radix, Ginseng Radix, Radix Sophorae Flavescentis and Radix Adenophorae to obtain final powder, adding Semen Juglandis, mashing, and making into quintuple-sized balls.

In recent years, Salvia miltiorrhiza has been used to treat cancer (esophageal cancer, gastric cancer, rectal cancer, liver cancer, etc.). ), often combined with Scutellaria barbata and Hedyotis diffusa.
