==Special Precautions of Flavanoids :==
* The only flavonoid shown to have negative side-effects in humans is catechin; large doses may cause fever, anemia and hives, but these symptoms are ameliorated once catechin supplementation is discontinued. Flavonoids often work in conjunction with vitamin C; large amounts can help improve the absorption of vitamin C in the body.Flavonoids may interact with some drugs used to treat shingles and chickenpox, such as acyclovir. Patients taking these drugs should consult with a licensed health care provider before taking flavonoid supplements. As always, patients should speak with a licensed health care practitioner before taking flavonoids or any other dietary supplements or herbal remedies.
