The tribes of the Amazon rainforest of Peru consider the cat's claw a sacred plant, and the action attribute on the mind and body.

immune stimulation

For reasons that still elude researchers, the Amazon seems to be a real nursery with species having a stimulating effect on the immune system. In a summary of research on the immunoregulatory properties of some plants in Peru, the author provides a list of at least six, including cat's claw, that could really improve the performance of the human immune system.

Tests in vitro and in vivo studies have revealed that some of the alkaloids nell'artiglio cat ensure to stimulate and regulate the production of lymphocytes in the body. The research also found that a standardized extract of the plant can protect cell DNA from some attacks and even repair some damage, if necessary, an effect that was observed during a study of 12 healthy volunteers. It has thus been observed in in vitro tests, the extract of cat's claw may induce apoptosis of cancer cells.

In 2001, it was administered for two months a standardized extract of cat's claw in volunteers who had just been vaccinated against pneumococcal infection. The researchers found significantly higher immune activity in these subjects than in the subjects of a control group (vaccinated persons not subject to the administration of the cat's claw).

Ingredients: standardized elderberry extract, standardized extract of cat's claw, magnesium stearate, silicon dioxide.

It seems that the substances to which this is attributable hypotensive effect are found only in negligible quantities nell'artiglio cat, which is why traditional herbalists have never mentioned this to make this system.
