This herb has been touted as a cure-all & rightfully so. Cats claw is naturally high in iodine which can do two important things for you: 1) it feeds your thyroid, which requires iodine to function; & 2) that same iodine helps fight infection. People with Crohn’s disease, celiac, diverticuloses or any colon problem that can cause an intestinal infection can benefit from regular use of cats claw to help control infection. In traditional Peruvian culture, this herb was used for arthritis, asthma, ulcers, infections and wound healing. Additional scientific studies show it effective in autoimmune disorders such as rheumatoid arthritis and Lupus. It is the inner bark of this prickly vine that is used. The vine is loaded with stickers that look exactly like a cat’s claw, curved and sharp.
