The appropriate dose for each person should be prescribed by a medical professional.

Cat's claw contains two types of alkaloids, on which its medicinal action depends:

  • Preparations to increase the immune system contain pentacyclic alkaloids (pteropodine, mitraphylline, uncarine and speciophylline). These components increase phagocytosis (The immune system attacks bacteria and external agents) and help fight bacterial and viral infections. The plant has anti-tumor action in vitro.

  • Cat's claw may contain other types of alkaloids, in smaller amounts, the so-called tetracyclic alkaloids (rhinophylline). These block the medicinal effects of the above and have anticoagulant and hypotensive effect.

Potential toxicity of cat's claw

Cat's claw has, above all, important contraindications that must be taken into account before deciding to perform the treatment.

The plant should not be given to people who have been transplanted from an organ, or people with autoimmune diseases.

Cat's claw during pregnancy and lactation

The safety of the plant has not been tested in pregnant women or during lactation. The components of the plant suggest that it is not adequate and that it should not be taken.

The alkaloids can cross the placenta and mammary barrier to the fetus or baby. The phytoestrogens it contains may have abortifacient effects, so cat's claw is contraindicated during pregnancy and lactation.
