Syrian rue is a plant that grows in parts of the United States, Asia, Africa, and Europe. The seeds of the plant can cause hallucinations and have stimulant effects when taken by mouth.
People take Syrian rue by mouth to terminate pregnancy and for the absence of a monthly menstrual period, cancer, depression, diabetes, painful menstruation, hypothermia, insomnia, pain, parasites, Parkinson's disease, and a joint disorder called rheumatoid arthritis.
In manufacturing, the Syrian rue seeds are used to produce a red dye to color rugs.
