If you are a cancer patient in Israel, your doctor is telling you to drink fresh lemon grass tea on the days that you go in for radiation or chemotherapy treatments. Ben Gurion University of the Negev researchers made a discovery last year that the lemon aroma in herbs like lemon grass kills cancer cells in vitro, while leaving healthy cells unharmed. In a fascinating article published in the Health section of Israel21c, it states that the study found the citral in lemon grass causes cancer cells to commit suicide in a process called apoptosis, a mechanism called programmed cell death. A drink with as little as one gram of lemon grass contains enough citral to signal the cancer cells to commit suicide.

Lemon grass is a perennial, aromatic tall grass with a light lemon scent used for culinary and medicinal purposes. For centuries, herbalists have used the herb as an effective digestive tonic and nervous system relaxant. Lemon grass oil is used to help clear blemishes and maintain balanced skin tone. Lemon grass is also used as an insect and mosquito repellent. Now, according to Israeli scientists, they can add cancer prevention to the list of attributes associated with lemon grass.
