Thyme is a plant found year-round that is native to the Mediterranean. It's grown in many European countries, Morocco, and the United States. The flowers, leaves, and oil of thyme are used in herbal medicine. Aside from its uses in medicine, thyme is also used in cooking, perfumes, soaps, cosmetics, and toothpastes.

Thyme is often used on the skin as a compress. The compress is prepared by pouring 1 cup of boiling water on 11 g of the dried leaves and flowers of thyme, letting it sit for 10 minutes, and using a cloth to apply it to the skin. The compress can be applied as needed. The same solution can be used buccally as a gargle.

Thyme is also taken orallyorallyto be taken by mouth (swallowed) (by mouth). The dried leaves and flowers of thyme are used to make teas, extractextractto get, separate, or isolate a desired active ingredients, and tincturetincturea desired active ingredient that is extracted from alcoholic solutions. The usual dose to prepare these is 1 g to 8.4 g used daily.

Thyme is used topicallytopicallyto be applied on the skin in herbal medicine as an antisepticantiseptican agent that prevents or reduces infection from wounds and antimicrobial for minor cuts and scrapes (i.e., an agent that stops bacteria from growing and causing infection). It is also used in some mouthwashes for its antiseptic effect.

Topical thyme has also been used for alopecia areata (bald patches), laryngitislaryngitisinflammation of the throat with symptoms of hoarseness, loss of voice, coughing, or difficulty swallowing, bad breath, tonsillitis, and mouth inflammation.

Thyme taken by mouth is traditionally used in herbal medicine as:

• an expectorantexpectorantan agent that thins mucus (phlegm) so that it can be absorbed or coughed up (a medication that helps clear mucusmucusa moist and sticky substance produced by the mucous membranes from the airways) to help relieve bronchitis and inflammation of the upper respiratory tract
• to help relieve coughs
• to help relieve gastrointestinal gas

Other conditions that oral thyme has been used for include whooping cough, sore throat, colic, diarrhea, skin disorders, as an appetite stimulant, and dyspraxia (a neurological disorder that affects movement).

Thyme oil, used together with the oils of lavender, rosemary, and cedar wood, has been shown to improve hair growth for people with alopecia areata (bald patches). However, more evidence is needed to suggest thyme as a treatment option for alopecia areata.

Thyme, in combination with cowslip, may help bronchitis symptoms (e.g., cough, chest congestion and fever), but more evidence is needed.

Taking thyme together with evening primrose oil, fish oils, and vitamin E has been shown to benefit children with dyspraxia.

There is not enough evidence to support the use of thyme for any other condition.
