Khellin has been used as an herbal folk medicine, with use in the Mediterranean dating back to Ancient Egypt, to treat a variety of maladies including: renal colic, kidney stones, coronary disease, bronchial asthma, vitiligo, and psoriasis. It is a major constituent of the plant Ammi visnaga, also known as Bishop's Weed. Once purified, khellin exists as colorless, odorless, bitter-tasting needle-shaped crystals and is classified as a gamma-pyrone, a furanochromone derivative. In the early 20th century, researchers searched for khellin analogs with lower toxicity and better efficacy. A number of drugs were discovered through this research, such as amiodarone and cromolyn sodium, which are used in current medical practice.
