Cat′s Claw

How to Use It

In a study of patients with osteoarthritis, 100 mg per day of a freeze-dried preparation was used. Cat’s claw tea is prepared from 1/4 teaspoon (1 gram) of root bark by adding 1 cup (250 ml) of water and boiling for ten to fifteen minutes. Cool, strain and drink one cup three times per day. Alternatively, 1/4–1/2 teaspoon (1–2 ml) of tincture can be taken up to two times per day, or 20–60 mg of a dry standardized extract can be taken once per day.12
