n the pharmaceutical industry, it is used as raw material for preparing gallic acid, pyrogallol and sulfonamides. Tannin is a hemostatic drug. It has been used in the treatment of laryngopharyngitis, tonsillitis, hemorrhoids and skin herpes. Internal use can stop diarrhea, intestinal preparation and so on. Tannin can form precipitation with metals, alkaloids and glycosides, which can detoxify these substances.

Gallic acid and pyrogallic acid can be prepared in chemical production. Tannin is used as a dilution in the treatment of boa constrictor mud. The tannin alkali liquor made of tannin powder and caustic soda in proportion can reduce the shear force and stickiness of thickened mud and improve the mud flow. On the contrary, if tannin powder is directly added into the mud, the mud pH will decrease due to its weak acidity, and it will be exchanged with clay particles. Reduce the surface hydration of clay particles, so that the formation of the network structure of clay particles, improve the shear force and viscosity of mud.
