Tannin

Tannins are a group of natural phenolic compounds found in various plants. They have antibacterial, anti-inflammatory and antifungal properties, making them useful for making medicines.

Tannins are obtained from various plants, such as oak bark, licorice root, serpentine rhizome and others. They can be isolated from plants by extraction with water or other solvents.

The main properties of tannins include their ability to bind proteins, resulting in inhibition of bacterial and fungal growth. In addition, tannins have anti-inflammatory properties due to their effect on white blood cells and immune system cells.

Some tannins are also used as dyes and pigments. For example, tannin extract from oak bark is used to dye leather and textiles.

Despite their health benefits, tannins can cause allergic reactions in some people. Therefore, before using tannin-based drugs, it is necessary to conduct a sensitivity test.

Tannins are a group of water-soluble phenolcarbolic tannins of yellow or brown color, which are the oxidation products of tannins contained in plants such as oak bark, alte roots, laurel and others. They have antimicrobial, anti-inflammatory and disinfectant effects and can be used as additives to cosmetics and medications.

Tannins are an example of natural biopolymers consisting of several phenol molecules linked to each other through methylene bridges. They are formed as a result of the biological oxidative breakdown of tannins and act on the microbial cell by binding free radicals and quenching the enzyme activity of sulfhydryl groups in the protein. These properties allow tannins to be used as an effective antimicrobial, anti-inflammatory, antiseptic and astringent agent.

Properties of tannins First of all, tannins also have a specific highly solid odor and are brightly colored. Tannins (such as astringent extracts from plant husks) can bind to proteins, form films on the tissues and membranes of bacterial cells, and increase the rigidity of structures, limiting their growth. As a result, protective functions are limited, and there is no positive effect on the human body. Because of these properties, their use for many types of infection is limited. Some antibiotics, such as metronidazole and thiamphenicol, are powerful antibacterial drugs designed to fight many infections. However, they can cause inhibition of intestinal bacteria, thereby reducing the effectiveness of treatment. On the other hand, many gram-negative
