Tannic acid, a natural polyphenolic compound, exhibits diverse biological activities. Its core benefits include:

1. Antibacterial and Antiviral Effects: It inhibits various bacteria, fungi, and viruses (e.g., influenza and herpes viruses) by disrupting pathogen cell membranes or suppressing enzymatic activity.
2. Anti-Inflammatory and Antioxidant Properties: It reduces the release of inflammatory factors, alleviating redness, swelling, and pain while scavenging free radicals to mitigate oxidative stress and protect cellular health.
3. Astringent and Hemostatic Actions: It promotes protein coagulation, constricts blood vessels, and accelerates wound healing, often used for superficial injuries.

4. Tumor Suppression: Studies indicate it can induce cancer cell apoptosis and block tumor angiogenesis, showing potential as an adjunct antitumor agent.

Additionally, it helps improve gut microbiota balance and inhibits fat absorption.

Tannic acid is widely utilized across multiple industries:

1. Pharmaceuticals: Used as a hemostatic agent, antimicrobial ingredient (e.g., in ointments and mouthwashes), and antiviral drug component, also treating diarrhea and oral ulcers.

2. Food Industry: Serves as a natural preservative (inhibiting microbes), clarifying agent (e.g., in beer and juice processing), and flavor enhancer in alcoholic beverages.

3. Cosmetics: Incorporated into skincare products (pore-tightening, oil-control, anti-acne) and sunscreens (antioxidant and UV protection).

4. Textiles and Dyes: Functions as a mordant to fix dyes and improve color fastness, and is used in leather tanning (softening and durability).

5. Environmental and Agricultural Uses: Treats industrial wastewater (precipitating heavy metals) and serves as a pesticide additive (suppressing pests and pathogens). Its natural properties align with green sustainable development trends
