Dandelion (Taraxacum officinale) is a botanical rich in beta-carotene and potassium. In herbal medicine, dandelion is typically used for its appetite-stimulating, digestion-aiding, and laxative effects.

Why Do People Use Dandelion Root?

Herbalists often use dandelion in treatment of the following conditions:

  • Type 2 diabetes
  • Eczema
  • gastrointestinal disorders
  • Rheumatoid arthritis
  • Liver disease
  • Heartburn
  • Health Benefits of Dandelion

    Although there is little scientific support for the medicinal use of dandelion, a number of studies suggest that the herb may help lessen inflammation and kill bacteria.

    Here's a look at several findings on dandelion's other health effects:

    1) Antioxidants

    In a 2003 study, scientists found that dandelion flower extract may fight free radicals (chemical by-products known to damage DNA).

    2) Diabetes

    Tests on diabetic mice show that dandelion extract may help regulate blood sugar and keep cholesterol in check. Of course, animal studies don't confirm similar efficacy in humans.

    See Natural Remedies for Diabetes.

    3) Cancer

    Preliminary research suggests that dandelion may show promise as an anti-cancer agent. In a 2008 study on breast and prostate cancer cells, researchers found that dandelion leaf extract slowed the growth of breast cancer cells and stopped the spread of prostate cancer cells. However, neither dandelion flower extract nor dandelion root extract had any effect on either type of cancer cell.

    Safety Concerns and Precautions

    While dandelion is generally considered safe, some people experience side effects such as heartburn, diarrhea, and upset stomach.

    Anyone with an allergy to dandelion, ragweed, chrysanthemums, marigold, chamomile, yarrow, daisies, or iodine should avoid use of this herb. Individuals with an inflamed or infected gallbladder, or blocked bile ducts, should also avoid medicinal use of dandelion.

    How to Use Dandelion

    Capsules, tinctures, and teas containing dandelion leaves, roots, flowers, or the entire plant can be found in many health food stores. Dandelion leaves can also be consumed as food, in salads or as a cooked green.
