On the Medicinal Use of Tannic Acid in China
Tannic acid is astringent and astringent in nature. In China, there is a wide range of medicinal uses.

I have heard that doctors use tannic acid as medicine to restrain and stop bleeding. Cover tannic acid can constrict local blood vessels, condense blood, and achieve the effect of hemostasis. In case of bleeding from gold sores, or bleeding from various traumatic injuries, apply medicine containing tannic acid, and the blood can stop gradually.

And the power of tannic acid in preventing diarrhea is also considerable. When gastrointestinal diarrhea occurs, tannic acid can act on the intestinal mucosa to coagulate its proteins, form a protective film, relieve intestinal irritation, and calm diarrhea.

Furthermore, tannic acid is toxic to sores, and it also has the ability to assist in healing. Its astringent properties can help sores converge, prevent exudation, and promote healing.

However, the way to use medicine depends on the trade-off. Although tannic acid has various effects, it should not be abused. Excessive dosage may cause adverse reactions and damage righteousness. Doctors should carefully review the condition and consider the dosage to achieve the best curative effect.

Therefore, tannic acid has a long history of medicinal use in China, with both advantages and disadvantages. If it is used well, it is a good medicine, and if it is misused, it is a harmful substance, which cannot be ignored.
