Some green teas and herbal teas have been traditionally used for detoxification of toxins. There is evidence that concentrated green tea extract aids in the production of detoxification enzymes according to the Arizona Cancer Center; however, the green tea was used in a supplemental form, not as a detox tea.

On the Other: FDA Doesn't Evaluate Detox Tea

The United States Food and Drug Administration (FDA) does not regulate supplements and herbs like detox teas. Therefore the safety, purity and strength of detox teas are always in question. Many detox teas have different herbs and ingredients. Reading the labels and researching the effects of the herbs used in detox tea might help in the decision to use a particular kind.

Bottom Line

No authoritative health organization has come forth with a decision on the safety of detox teas. The American Council of Science and Health warns that just because detox teas are natural does not mean they are safe. Detox teas, especially if misused, can have some harmful effects like dehydration, nausea and vomiting. Consult with your doctor about using detox tea to be safe.
