Burdock is a stimulating (as well as a nutritive) tonic and is often recommended as a cleansing herb. It is considered a blood purifier and is used for acne, eczema, psoriasis, and other skin problems and for liver stagnation and difficulty with fat digestion. It is indicated for rheumatism, arthritis, gout, cystitis, and anorexia nervosa. Recent research has shown it to be antimutagenic, perhaps acting as a cancer protector. Antimicrobial and antitumor properties have also been reported. You can also use burdock as a nutritive food. Add 1 teaspoon of the sliced root (found in many markets) to soups and stews.
