Cat's Claw

Uncaria tomentosa

Deep in the Amazon, the Asháninka and other indigenous peoples have turned to cat's claw for centuries, simmering its tough inner bark into a dark decoction to ease sore joints, settle the stomach, and help the body recover after illness. Healers valued it as a general tonic for weathering the rainforest's fevers and infections, and it was often shared communally as a strengthening drink. Its reputation traveled with Spanish colonizers and eventually reached Western herbalism in the twentieth century, where it became one of South America's most sought-after botanical exports. The vine's hooked thorns, which let it scale trees toward sunlight, gave it both its common name and a certain folk mystique as a plant that claws its way toward the light.

Safety.

Cat's claw is traditionally avoided during pregnancy and breastfeeding, and by people with autoimmune conditions such as lupus or rheumatoid arthritis, since it may stimulate the immune system. It can also interact with immunosuppressant medication, blood thinners, and blood pressure medications.
