The most current available medical and scientific literature indicates that this dietary supplement should be standardized to 3% alkaloids and 15% total phenols per dose.
An extract of Cat's claw from Europe containing only pentacyclic oxindole alkaloids (mainly isomitraphylline isolated from the root) may be more beneficial as an immune enhancing product than the standard mixture of pentacyclic and tetracyclic alkaloids. When the two chemotypes are mixed, immune enhancement may be decreased. This product should be standardized to not less than 1.3% pentacyclic oxindole alkaloids and not more than 0.06% tetracyclic oxindole alkaloids per dose. (2)
Cat’s claw is reported to have the ability to soothe irritated and inflamed tissues and help eliminate harmful bacterial and viral invaders from the gastrointestinal tract. Studies have also looked into the herb’s function in supporting the immune system. (3) Some of the key components of cat’s claw have been studied for their ability to fight infection and boost overall immunity. (4) , (5) , (6) , (7)
As an antioxidant, cat’s claw use in the treatment of cancer has been investigated. (8) Antioxidants reduce the carcinogenic toxin buildup that stimulate abnormal cell development. Research indicates that cat’s claw may be able to target potential cancer cells and inhibit their development through different types of activity. (9) , (10) , (11)
Cat’s claw may also play a role in reducing the risk of cardiovascular diseases by helping to strengthen capillaries and facilitate normal blood flow throughout the body. (12)
The anti-inflammatory effect of cat’s claw was observed in patients with active rheumatoid arthritis. (13)
