Additionally， tannic acid is used in the pharmaceutical industry for its medicinal properties. It has been used traditionally to treat diarrhea， sore throats， and skin conditions. Tannic acid is also used in wound healing products， due to its ability to promote blood clotting and reduce inflammation.

Furthermore， tannic acid has applications in the textile industry， where it is used as a mordant in fabric dyeing to improve color fastness. It is also used in the production of ink and as a corrosion inhibitor in metalworking.

Overall， tannic acid is a versatile compound with a wide range of applications in various industries. Its astringent properties， as well as its ability to interact with proteins， make it a valuable ingredient in products ranging from leather goods to skincare products.
