Khella Overview

Khella Khella (Ammi visnaga) is a plant native to the Meditearran region and has traditionally been used as an herbal supplement. Khella contains several constituents, including 'khellin', which is found in the seeds of the plant. Khellin dietary supplements have been used to treat a variety of ailments, particularly respiratory problems such as asthma and bronchitis, and cardiovascular issues such as angina pectoris. It is believed to work by relaxing the smooth muscles of the airways, making it easier to breathe. It also is thought to dilate the blood vessels, which can help to lower blood pressure and improve blood flow to the heart. Khella has also been used for dermatological conditions, such as psoriasis and vitiligo.
