Fennel seeds

Fennel is a perennial, pleasant-smelling herb with yellow flowers. It is native to the Mediterranean, but is now found throughout the world. Dried fennel seeds are often used in cooking as an anise-like spice. … In foods and beverages, fennel oil and fennel seed are used as flavouring agents.

Fennel is used by mouth for excessive crying in infants , indigestion, menstrual cramps, and symptoms of menopause, but there is no good scientific evidence to support these uses.
