Thyme is an herb in the mint family. It’s closely related to oregano. Like oregano, it is indigenous to the Mediterranean. It was used by the ancient Egyptians in their embalming rituals; and by the ancient Greeks as incense and in their baths. The Romans probably spread thyme throughout the rest of Europe. They used it to purify their living quarters and to flavor certain cheeses and liqueurs.

During the middle ages, thyme was placed under the pillow to ward off nightmares. As an incense, it was used at funerals and placed on coffins. The herb also has a history of being associated with courage.

Thyme is low in most nutrients but it does contain small amounts of potassium, vitamin A, vitamin C,  and magnesium.

Thyme is used in both fresh and dry forms. As a dried herb it holds its flavor better than most other herbs.

There are many varieties of thyme but common thyme (Thymus vulgaris) is typically used in cooking. Essential oil from common thyme (oil of thyme) has a number of compounds with antimicrobial properties. The essential oil contains 20-54 percent thymol as well as p-cymene, myrcene, borneol, and linalool. Thymol is an antiseptic. It is an active ingredient in some commercially-made mouthwashes such as Listerine. Before modern antibiotics were in use, oil of thyme was applied to bandages to help with healing.

Thyme has been linked to a wide range of possible health benefits. As an antibacterial, it may help fight acne, for example. One kind of thyme extract may help reduce the heart rate (in rats). Thyme essential oil, in some forms, is sometimes used as a natural cough remedy.

It’s also likely that if you take thyme essential oil or thyme supplements on a regular basis that you could kill off the good bacteria in your gut as well as any harmful bacteria.

Thyme may also be effective against fungus such as yeast. One recent study found that very small doses of thyme essential oil acted as a fungicide against Candida albicans, a common cause of yeast infections, even when the fungus was resistant to the prescription drug fluconazole.
