Chamomile
Genus Matricaria / Anthemis

Four different oils are sold as chamomile, and only two of them are chamomile. Roman chamomile is pale and smells of apples, while German chamomile comes out of the still deep blue. Distillation turns a colourless compound in the flower into chamazulene, which gives both the colour and the effect on inflamed skin.[1] The other two are Moroccan plants from a different genus, and are in fact the same plant under two names. In cell and mouse tests, German chamomile oil calmed psoriasis-like skin inflammation.[2]

- $$$$Chamaemelum nobile flowers are hand-harvested and yield very little oil - roughly 0.2-0.3% by weight; the labour-intensive harvest in France, England, and Hungary makes it one of the pricier herb oils
Roman chamomile smells like a bruised apple, sweet and fruity with no medicinal edge at all. Around three quarters of the oil is a single family of esters, which is unusually pure for an essential oil. That is what makes it so gentle, and why it is the chamomile reached for at bedtime. In tests on isolated gut muscle, the oil relaxed contractions by up to seven tenths.[3] Reviews also credit it with easing pain and swelling and helping sleep.[4]

- Price
- $$$$Ormenis multicaulis (not a true chamomile) is harvested wild or cultivated in Morocco at larger scale than Roman or German chamomile; the higher yield and lower harvest cost make it the most affordable chamomile-type oil
Moroccan chamomile is not a chamomile at all, and it is the same plant as wild chamomile, sold under a second name. It smells warm, herbal and rustic, with a camphor edge and none of the apple sweetness of the real thing. The oil is built on unusual alcohols, santolina and yomogi, that hardly appear anywhere else. In lab tests it worked better against Staphylococcus aureus and E. coli blended with other oils than it did alone.[5] Later work confirmed it pulls its weight in such blends.[6]

- Price
- $$$$Matricaria chamomilla is widely cultivated in Eastern Europe but the small flower heads still yield under 0.5% oil; high demand for the distinctive blue oil sustains a premium price despite broad cultivation
German chamomile is the blue one, and the blue is made in the still. The fresh flower contains none of it: heat turns a colourless compound called matricine into chamazulene, which is both the pigment and the active ingredient.[1] That makes this the chamomile for angry skin rather than for sleep. In cell and mouse tests, the oil itself calmed psoriasis-like skin inflammation and brought down the immune signals driving it.[2]
Wild Chamomile

- Ormenis Flower, Mixed Chamomile, Ormenis multicaulis

- $$$$Wild-harvested in small batches from uncultivated land; variable seasonal yield and the cost of manual collection mean pricing is higher than conventionally farmed chamomile despite modest raw material demand
Wild chamomile is not a chamomile but a Moroccan daisy. It is sold under two names, Ormenis mixta and Ormenis multicaulis, which botanists now treat as the same plant. Its oil is built on germacrene and 1,8-cineole, giving a green, faintly eucalyptus-like edge the true chamomiles lack. In lab tests the oil was strong at mopping up the unstable molecules that damage cells, better than the geranium oil tested alongside.[5] Against bacteria it was weaker, though the two oils together beat either alone.[5]
