Antiseptic;  Antispasmodic;  Aromatic;  Bitter;  Diaphoretic;  Digestive;  Diuretic;  Expectorant;  

The seed, and especially the essential oil in the seed, is strongly antiseptic, antispasmodic, aromatic, bitter, diaphoretic, digestive, diuretic, expectorant and tonic[238]. It is used internally in the treatment of colds, coughs, influenza, asthma, diarrhoea, cholera, colic, indigestion, wind, oedema, arthritis and rheumatism[238, 240]. The seed is harvested when fully ripe and either distilled for the essential oil or dried for later use[238]. The seed contains about 4 - 6% essential oil, of which 45 - 55% is the strongly antiseptic essential oil 'thymol'[240]. The essential oil is also added to cough medicines[238]. The root is carminative and diuretic[240].


Other Uses

The seeds are rich in essential oil, 30 - 35% of which is thymol[240], which is more commonly found in Thymus species[238]. The essential oil is added to epoxy derivatives[238]. It is used in perfumes[266].
Cultivation details
Requires a moist soil in a sunny position[238]. This species is not frost tolerant[238], 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.
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].

We sowed a ton of seeds (obtained from an indian grocery store) on a small 4" by 4" flat, and we got relatively good germination. We are about to transplant them (very late in the season) and will see what they end up doing, but so far they look healthy.

Ajowan, although rarely encountered in the wild, is listed in the local Flora as a supposedly-native species.   Mar 2 2012 12:00AM
I had been looking for this material for years, and I just bought some today after striking a random conversation with my neighborhood's grocer about what could be used to soothe an angry stomach! Nobody ever understood what I was talking about when I asked for "Ajwan", and even less when I was using the "official" Hebrew name, Kamnunith Koptith. It turns out that Trachyspermum ammi's commercial name in Israel is "Nakhwa", or something like that. Let's hope that stuff germinates profusely, I need to take a few good close-up photos of this plant for my botanical portraits collection!
