Ammi visnaga (L.) Lam. - syn. Daucus visnaga L.; Visnaga daucoides Gaertn. - Apiaceae
khella, toothpickweed, Zahnstocher-Ammei, Zahnstocherkraut, Bischofskraut

Taprooted erect annual herb, 0.50-1.20 m high, native to the Mediterranean, Southwest Asia, North Africa, naturalized in North America, cultivated elsewhere; lower leaves long-petioled, pinnate; higher leaves bi- or tripinnate, aristate; flowers white or yellow-white on long-stalked umbels; seeds small, oblong-ovoid.

„Used in oriental countries for the production of toothpicks, with their spicy taste is welcome.“ http://de.wikipedia.org/wiki/Bischofskraut

Preparations of the seeds have been used to treat diseases of the heart like angina pectoris, coronary insufficiency, tachycardia, extrasystoles; and of the respiratory tract, such as asthma and whooping cough. Side effects include dizziness, reversible cholestatic jaundice, pseudoallergic reaction, and elevated levels of liver enzymes (transaminases and gamma-glutamyltransferase). Ammi visnaga is one of the species having been evaluated negatively due to missing data on efficacy.

„The essential oil of Ammi visnaga L., collected at Didouche Mourad-Constantine (North Eastern Algerian), is mainly characterized by the presence of isobutyl isobutyrate, linalool, 2,2-dimethylbutanoic acid [= 4-methyl valeric acid], thymol, bornyl acetate and croweacin [= safrole] as the major components. The antibacterial activity of this essential oil against several microorganisms was investigated. The best antibacterial activity was obtained against Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae strains.“

The fruits of A.visnaga are rich sources of the furanochromones khellin and visnagin, which are smooth muscel relaxants and vasodilators.
