You may assume herbs are safe to use because they are found in nature. Unfortunately, this is not true. All herbs have the capacity to cause side effects and interact with your medications, and burdock is no exception. Burdock root has been used for centuries to treat a wide range of ailments, according to the University of Maryland Medical Center. However, it is important to consult your doctor before taking burdock.
Background
You can find burdock growing in the United States, though it is native to Northern Asian and Europe. It is a member of the daisy family and has distinctive purple flowers and heart-shaped leaves. Burdock's main constituents are fatty oils, carbohydrates and sterols -- or plant steroids and tannins -- a bitter plant substance. Clinical data on the active substance responsible for burdock root's effects is lacking. However, it may have antioxidant, ant-inflammatory and antibacterial properties, according to the UMMC.
Uses
You can get burdock as a singular extract or combined with other herbs. You can also drink burdock as a tea. Historically burdock has been used as a blood purifier and a diuretic. Burdock is used topically for eczema, acne and psoriasis. Burdock is used in traditional Chinese medicine to treat colds and sore throats. In Europe and parts of Japan, burdock is cultivated as a vegetable, according to the UMMC.
Safety
It is best to consult a health provider with botanical medicine knowledge. According to the UMMC, burdock is considered safe at recommended doses, so take burdock as directed. It is important to purchase burdock from a trusted, reputable source because some preparations may be contaminated. You may experience an allergic reaction if you are sensitive to ragweed or daisies. Because burdock can have a diuretic effect, you should not take it if you are dehydrated. You should not take burdock if you are pregnant or nursing.
Side Effects
Clinical studies evaluating the safety of burdock are lacking. It is important to use caution if you choose to take burdock. The only side effects known are related to allergy, but that does not mean that there are not any. The toxicity level is unknown, so it may not be safe to take high doses. According to the University of Pennsylvania Medical Center, burdock has the capacity to interact with diabetes medications. Consult your doctor if you are currently taking medication.
