Saffron

Saffron crocus is a flowering plant that is usually used as a spice. However, it is also used in herbal supplements. Some of the compounds in saffron may have anticancer activity; others may stimulate the secretion of stomach acids and can stimulate the contraction of smooth muscles (such as the uterus). Compounds in saffron may also have some effect on lowering cholesterol and triglyceride levels.
