- Dandelion greens are edible and are a rich source of vitamin A. Dandelion has been used in traditional medical systems, including Native American, traditional Chinese, and traditional Arabic medicine.

What Do We Know About Safety?
- The use of dandelion as a food is generally considered safe. However, some people are allergic to dandelion; allergic reactions are especially likely in people who are allergic to related plants such as ragweed, chrysanthemums, marigolds, and daisies. The safety of using dandelion supplements for health-related purposes is uncertain.
Keep in Mind
- Tell all your health care providers about any complementary or integrative health approaches you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care.
