What is Khella?

Khella is a plant. The dried, ripe fruit is used to make medicine. People commonly prepare an "extract" by removing khellin, one of the active chemicals in khella, and dissolving it in a liquid that is then used as medicine. Khella is less commonly prepared as a tea.

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.

Insufficient Evidence to Rate Effectiveness for...

  • Psoriasis: Early research suggests that taking khellin, a chemical in khella, by mouth in combination with sunlight exposure helps clear skin sores in people with psoriasis.
  • A skin discoloration disorder called vitiligo. Research on the effects of khella for treating vitiligo shows conflicting results. Some research shows that taking khellin, a chemical in khella, by mouth or applying it to the skin improves skin discoloration when used along with ultraviolet light therapy. However, other research shows that applying khellin to the skin along with sunlight exposure doesn't improve skin discoloration. Also, some research shows that khellin therapy requires longer treatment durations and higher light doses to improve skin discoloration similarly to the effects of psoralen plus ultraviolet light therapy (PUVA).
  • Stomach cramps.
  • Kidney stones.
  • Menstrual cramps.
  • Premenstrual syndrome (PMS).
  • Asthma.
  • Bronchitis.
  • Cough.
  • Whooping cough.
  • High blood pressure.
  • Irregular heartbeat (arrhythmias).
  • Congestive heart failure (CHF).
  • Chest pain (angina).
  • "Hardening of the arteries" (atherosclerosis).
  • High cholesterol.
  • Other conditions.
More evidence is needed to rate the effectiveness of khella for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
