Burdock has an ancient and respected reputation as a nutritive liver tonic that helps to clean and build the blood, while its diuretic action of burdock helps in the elimination of waste materials. Taken internally, this root promotes sweating and urination. The roots, leaves, and seeds of burdock can all be used, but in commercial preparations, you'll most commonly find the root. Rich in minerals, this plant is used as a food by many cultures. Burdock helps to cleanse the body from the inside out and is most useful in those conditions that can be traced back to liver disorders or a general overload of toxins in the system. Burdock root oil extract (Bur oil) has traditionally been popular in Europe as a scalp treatment applied to improve hair strength, shine, and body, and to combat hair loss. It has been used to ease dandruff and scalp itching. Modern studies indicate that burdock root oil extract is rich in phytosterols and essential fatty acid required for healthy scalp and natural hair growth.
