Tannins - Action and Properties
Tannins, also known as tannins, are natural chemical compounds found mainly in plants. They are distinguished by their characteristic astringent taste and are widely used in the food, pharmaceutical and cosmetic industries. Thanks to their astringent and antioxidant properties, tannins play an important role in protecting plants from pathogens, but also offer numerous health benefits for humans. In this article, we will discuss what tannins are, their properties and how they can support health.
What Are Tannins?
Tannins are a group of polyphenolic plant compounds that have the ability to bind to proteins and other macromolecules, forming water-insoluble complexes. They are found in the bark of trees, leaves, fruits and seeds of many plants. Plants produce tannins as a defense mechanism against herbivores and microorganisms. For humans, tannins are primarily known for their astringent taste, which we can experience in tea, red wine or pomegranate fruit, for example.
Tannins - Chemical Composition
Tannins are divided into two main groups:
- Condensed tannins (flavanoids): Derived from the polymerization of flavonoids such as catechins. They are more stable and more difficult for microorganisms to break down.
- Hydrolyzable tannins: They are easily broken down by water and can release gallic acid or ellagic acid, which are responsible for their antioxidant properties.
Tannins - Action
Anti-inflammatory and Antiseptic Properties
One of the most important properties of tannins is their ability to reduce inflammation and protect against infection. Thanks to their astringent effect, tannins can help heal wounds by inhibiting bacterial growth and speeding up the healing process. This is why tannins are often used in cosmetics to make tonics, which are designed to cleanse the skin and reduce inflammation.
Support for the Gastrointestinal System
Tannins also have beneficial effects on the digestive system. In traditional medicine, they are used to treat diarrhea and other stomach problems, thanks to their astringent effect and ability to reduce the permeability of intestinal mucous membranes. Tannins can also neutralize toxins produced by pathogens, which contributes to faster recovery.
Antioxidant Activity
Tannins, especially hydrolyzable ones, are powerful antioxidants, meaning they neutralize free radicals and protect cells from oxidative stress. Oxidative stress is one of the main factors accelerating the aging process and contributing to the development of chronic diseases, such as heart disease and tumors. Because tannins counteract cell damage, they can promote overall health and longevity.
Use of Tannins in Medicine and Cosmetics
Tannins have found wide application in a variety of fields, from the food industry to pharmaceuticals and cosmetics. Their astringent and antibacterial properties make them valuable in the production of diarrhea medicines and in cosmetics for problematic skin, such as acne. In addition, tannins are used in the production of wines, where they affect their taste and preservative properties.
In the context of natural supplements, ENCANN products may contain tannins in herbal extracts. An example is ENCANN Ashwagandha Liquid Extract, which supports health nervous system and endocrine function. Ashwaganda also contains tannins, which further enhance its antioxidant and anti-inflammatory effects(
