Da Chaihu Tang

Da Chaihu Tang

Three qian of bupleurum, three qian of pinellia, three qian of white peony, three qian of scutellaria, two qian of citrus peel, half a qian of rhubarb, three qian of ginger, and three dates.

Scutellaria alone clears fire both inside and outside the body, while ginger, dates, and bupleurum help expel evil from the surface, and pinellia, white peony, citrus peel, and rhubarb help expel evil from the interior. It is a formula that addresses both the exterior and interior, with a greater emphasis on interior remedies. Later formulas like Shuangjie San and Tongsheng San both originated from this set. When used to treat blood-related illnesses, we can either add exterior remedies or interior remedies, depending on the situation.

[Note] The formula comes from "Shanghan Lun." It is a dual-action formula that addresses both the exterior and interior. It can be used for blood-related illnesses with heat.
