Echinophora sibthorpiana, commonly known as Tarhana herb or Turkish pickling herb (Turkish çörtük), is a biennial or perennial herb native to southeastern Europe, Crimea, western and Central Asia, and northeastern Afghanistan. It is sometimes used as a flavoring in tarhana and in pickles. It may also improve the fermentation of tarhana. The primary constituents of its essential oil are δ-3-carene, methyleugenol, and α-phellandrene. Some authors indicate that Hippomarathrum cristatum is the "tarhana herb"....read more on Wikipedia.
