Khella is used for respiratory conditions including asthma, bronchitis, cough, and whooping cough.
It is also used for diseases of the heart and blood vessels (cardiovascular disorders) including high blood pressure, irregular heartbeat (arrhythmias), congestive heart failure (CHF), chest pain (angina), "hardening of the arteries" (atherosclerosis), and high cholesterol.
Other uses include treatment of diabetes, colic and abdominal cramps, liver and gallbladder disorders, kidney stones, and fluid retention.
Women sometimes use khella for menstrual pain and premenstrual syndrome (PMS).
Some people apply khellin taken from khella directly to the skin and then expose the area to light to treat skin problems such as vitiligo, psoriasis, and patchy hair loss (alopecia areata).
It is also put on the skin to treat wounds, skin redness and swelling (inflammation), and poisonous bites.
Be careful not to confuse khella with its less commonly used relative, bishop's weed. The two species contain some of the same chemicals and work similarly in the body, but khella is more commonly used for heart and lung conditions, and bishop's weed is more commonly used for skin conditions.
