Spiked thyme

Thymbra spicata

Also calledZahter / karabaş kekik (Turkish) · Za'atar (Lebanon, Levant)

A small aromatic shrub of the Eastern Mediterranean whose carvacrol-rich leaves are one of the plants sold as za'atar in Lebanon and as zahter, a kind of kekik, in Turkey. It is eaten in salads and drunk as tea, and Turkish folk medicine uses the tea for stomach ache, respiratory infections, kidney stones, colic, bronchitis and high cholesterol. Laboratory and mouse studies support antimicrobial and cholesterol-lowering effects; there are no human trials.

What it is used for

  • Used for hypercholesterolaemia in Turkey. In mice on a high-fat diet, extracts lowered total and LDL cholesterol and triglycerides, raised HDL and protected the liver; anti-steatotic activity of the leaves has also been reported in cell studies.1,2,3

  • The essential oil (about 54% carvacrol) inhibited Staphylococcus aureus and Candida parapsilosis and, below inhibitory doses, blocked biofilm formation and quorum sensing in vitro; a separate study reports synergy of extracts with antibiotics against multidrug-resistant S. aureus and Klebsiella.1,4
