The burdock plant has been used in Chinese medicine for thousands of years and is a staple in Western herbal medicine practices as well. Its roots, flowers, and other plant parts are believed to have a variety of benefits.

Burdock root contains vitamins, minerals, and antioxidants that are shown to improve health. Traditional medicinal uses include:

• Prevention and treatment of cancer: Burdock root contains the antioxidants quercetin and luteolin, which have properties that may prevent cancer cells from growing and mutating. A 2011 study found free radicals in burdock root may stop certain cancers from spreading in a laboratory,2 however, Memorial Sloan Kettering Cancer Center warns there is insufficient evidence to support burdock's use in treating or preventing cancer.
• Soothing a cough and cold: Burdock root tea has traditionally been used as a decongestant and expectorant for colds and cough. While the science is limited on this, burdock does contain vitamin C, which is shown to boost the immune system; some research has also shown that it has antibacterial properties.
• Improving liver health: Burdock root has been used to detoxify the liver and body for centuries. A 2002 study of rats found the herb can help reverse liver damage caused by excessive alcohol consumption,5 though a direct correlation to results in humans cannot necessarily be made.

• Reducing wrinkles: Burdock root contains antioxidants quercetin, luteolin, and phenolic acids, which fight free radicals and combat the signs of aging. One study found that cream containing burdock root extract helped reduce the appearance of skin wrinkles.7
• Improving hair: Phytosterols in burdock root are believed to boost scalp and hair health, relieve dandruff, and improve hair follicles to prevent hair loss and improve thickness.
• Eliminating excess water weight: Burdock root is used in traditional Chinese medicine as a diuretic to promote urination and sweating. There is limited scientific evidence to support this claim, however.
