Japanese knotweed

Japanese knotweed is an East Asian plant that has been used for centuries by the Chinese and Japanese. It is the plant richest in resveratrol , a polyphenol (also found in red wine) which has aroused great interest since its discovery in 1939.

The rhizome (listed in the Chinese Pharmacopoeia) is the part of the plant which contains the most resveratrol. We find 20 to 50 times more than in other parts. Other compounds of pharmacological interest are present in Japanese knotweed. They can be grouped into five classes: anthraquinones, stilbenes (including resveratrol), flavonoids, lignans and phenolic compounds.

Scientific studies have suggested that resveratrol may have health-promoting properties, such as its potential antioxidant and anti-inflammatory effects. These properties have generated considerable interest in resveratrol as a bioactive compound.

Antioxidant activity helps protect the body's cells from excessive production of free radicals. This action can be seen on the skin. Indeed, ultraviolet rays cause premature aging of the skin which results in an alteration of the connective tissues of the dermis, rich in collagen, causing the appearance of wrinkles.

The anti-inflammatory activity of resveratrol is linked to its ability to inhibit the synthesis and release of pro-inflammatory mediators.

Antioxidant and anti-inflammatory, resveratrol has no shortage of benefits for cardiovascular protection .

We use Japanese knotweed in B-Cell for its richness in resveratrol which helps fight oxidative stress and inflammation.
