The seed, and especially the essential oil in the seed, is strongly antiseptic, antispasmodic, aromatic, bitter, diaphoretic, digestive, diuretic, expectorant and tonic[1]. It is used internally in the treatment of colds, coughs, influenza, asthma, diarrhoea, cholera, colic, indigestion, wind, oedema, arthritis and rheumatism[1][2]. The seed is harvested when fully ripe and either distilled for the essential oil or dried for later use[1]. The seed contains about 4 - 6% essential oil, of which 45 - 55% is the strongly antiseptic essential oil 'thymol'[2]. The essential oil is also added to cough medicines[1]. The root is carminative and diuretic[2].

Propagation

Seed - we have no information for this species, but suggest that you try sowing the seed in situ in April. If this is not successful, then an earlier sowing in the greenhouse in March, planting out after the last expected frosts might be better[K]. It is quite possible that this species will not like to be transplanted, so either sow 4 - 5 seeds per pot, or sow in a tray and transplant to individual pots as soon as the seedlings are big enough to handle[K].
Cultivation

Requires a moist soil in a sunny position[1]. This species is not frost tolerant[1], but it might be possible to grow it outdoors in Britain as a spring sown annual[K]. The plant is extensively cultivated as a spice in S. W. Asia.
