Burdock root is the common burr; that’s right, that sticky thing that clings to your dog (and you) when you take a walk in the wild. This herb is an excellent blood cleanser and one I like for acne, psoriasis and other itchy skin conditions. It is also an excellent antihistamine so if you think you’ve had an allergic reaction (hives or itching), take burdock root. Burdock root is also used in cooking, particularly in Japanese dishes. Burdock root extract is easy to take and easy to keep with you for emergencies.
