Scientists have long valued the rich composition of medicinal substances contained in plant fibers, and determined their immunostimulating effect. To date, the entire composition of the Cat’s Claw plant has not been studied, and all its medicinal properties have not been established.

Now the basic research of the Cat’s Claw properties is carried out in the following directions:

  • Effects on cancer cells;

The unique medicinal properties of the drug are provided by the group of oxyindole alkaloids (isopteropodins) contained in its composition. They activate T-lymphocytes, which destroy the cells of tumors in the tissues of the body. Substances in the Cat’s claw activate the processes of phagocytosis in tissues, normalize the balance of immunoglobulins in the blood, improve the rheological characteristics of the blood, significantly reducing the risk of developing thrombosis.
