What is Cat’s Claw?
Cat’s Claw (Uncaria tomentosa) is a woody vine native to the Amazon rainforest, named for the claw-like thorns that grow along its stem.

Key Nutrients & Compounds
Cat’s Claw contains oxindole alkaloids, which are believed to be responsible for its immune-modulating effects. It also contains quinovic acid glycosides with anti-inflammatory properties, as well as polyphenols, proanthocyanidins, and sterols that provide antioxidant support and cellular protection.
Health Benefits
Cat’s Claw helps modulate immune function, making it useful for people with autoimmune conditions or chronic infections. It reduces inflammation, particularly in the joints, and may alleviate symptoms of arthritis. The herb also offers antioxidant benefits that protect cells from damage and may support digestive health by combating harmful pathogens.
Recommended Dosage
Standard doses range from 250 mg to 1,000 mg per day, depending on the concentration and extract type. For teas and decoctions, 1–2 grams of dried bark steeped in hot water is common. Long-term use should be cycled or guided by a healthcare provider.
