Wild thyme is a commonly used domestic remedy, being employed especially for its antiseptic properties and its beneficial effect on the digestive system. The whole plant is anthelmintic, strongly antiseptic, antispasmodic, carminative, deodorant, diaphoretic, disinfectant, expectorant, sedative and tonic. It is taken internally in the treatment of bronchitis, catarrh, laryngitis, flatulent indigestion, painful menstruation, colic and hangovers. It is said to be effective in treating alcoholism. It should not be prescribed for pregnant women.
Externally, it is applied to minor injuries, mastitis, mouth, throat and gum infections etc. The plant can be used fresh at any time of the year, or it can be harvested as it comes into flower and either be distilled for the oil or dried for later use.
Its seeds are used as a vermifuge. Wild thyme contains all the medicinal properties of the more commonly used garden thyme (Thymus vulgaris), though in a lesser degree. Essential oil distilled from the leaves is used in the treatment of stress-related conditions, though it can cause allergic reactions.
