Tannic acid is a type of astringent tannin derived from plants, with antibacterial, antifungal, and antioxidant properties. It is used for industrial purposes and can be added to creams and ointments to help heal wounds and combat muscle and joint problems.

Tannic acid is naturally present in some types of wood and is commonly used to tan animal skin to produce leather.
A tannin is an astringent chemical substance derived from plants. Tannic acid is a type of tannin that has a fairly weak acidity. In some trees, this chemical can act as protection against pests and fires, and humans are thought to benefit from the substance’s antibacterial, antifungal, and antioxidant properties. It is also used for industrial purposes, such as leather manufacturing and wood staining.
This substance is usually found in the form of a yellow, white or tan powder that tends to dissolve easily in water. It generally does not have a smell, but the taste is one that can make a person curl.
Since it will cause constipation in humans, tannic acid can be used to treat diarrhea. It can also be used to reduce the swelling of hemorrhoids and control internal bleeding. Externally, tannin can be added to creams and ointments to help combat muscle and joint problems and to help heal wounds. It can also be used for antifungal treatment of the feet, toenails or fingers.
People are warned not to consume large amounts of tannic acid and it shouldn’t be consumed on a regular basis. While it can be beneficial in many ways, tannin can also have negative effects.
One drawback is that it is believed to interfere with iron absorption. Iron is an essential mineral for maintaining proper human health, especially with building strong red blood cells. Tannic acid can also have a negative effect on the digestive process. The use of this substance has been associated with severe liver and kidney damage.
These negative symptoms are associated with the use of the substance in its pure form or in ways not recommended by medical experts. People are not considered to be at risk of adverse effects with normal use and consumption. For example, tannins can be absorbed into wine from the oak barrels it’s stored in and aren’t thought to cause many serious side effects for most people.
Tannic acid is naturally present in some types of wood such as oak and redwood. It is sometimes used to pretreat other types of wood that need to be stained. This substance is also commonly used to tan the skin of animals to produce leather, and tanning is often claimed to have been the first use man made of it.
