Ammi visnaga Khellin, amiodarone, nifedipine. Ammi visnaga belongs to the Umbellifereae and grows in the Nile delta. Khella, made from the fruits has been used for centuries to treat renal colic, common in Egypt because of damage to the urinary tract caused by schistosomiasis. Anrep a pharmacologist at Cairo University had an assistant with both renal colic and angina pectoris. When he took Khellin purified from Khella, both improved. Subsequently Anrep showed that the improvement in Angina was due to dilatation of the blood vessels supplying the heart. Search for the active principal in Khellin lead to the discovery of Amiodarone which is now used primarily for the disorders of heart rhythm (arrhythmias). Nifedipine, used for the treatment of high blood pressure and angina, was developed from other precursors found in khellin.
