Chrysanthemum tea is best not to drink, because menstrual blood will take away some iron, so women should supplement iron-rich foods at this time, such as spinach, apples, grapes and so on. However, because tea contains as much as 30% to 50% tannic acid, it will hinder the absorption and utilization of iron by intestinal mucosa, and it is easy to precipitate with iron in chyme or iron stone in blood-enriching drugs in the intestine.

Chrysanthemum tea is a kind of herbal tea made of chrysanthemum. Chrysanthemum tea is made by picking flowers, drying in the shade, sunning and baking.
