The charming Chamaemelum nobile flowers, with white petals and deep yellow centers, create a stunning, blue essential oil that is warm, slightly fruity, and sweet. Roman chamomile essential oil is highly valued for its potential to ease muscle spasms, like those that often come with a monthly cycle. This oil is also helpful when looking to reduce minor pain and inflammation or when seeking assistance in quieting an upset stomach. Emotionally and energetically, Roman chamomile essential oil is profoundly calming and a lovely choice when looking for sleep support or wanting to quiet an anxious mind that is perhaps overthinking and worrying excessively.
The double variety (cultivar) is the main source of the commercial drug today, and has been certainly known since the 18th century; it is sterile, and is propagated vegetatively by suckering.
Our certified organic Roman chamomile essential oil is steam distilled from delicate Roman chamomile flowers grown in the rolling, green English countryside. We love putting this oil into a blend for ushering deep sleep as it is pleasantly sedative, and, so welcome during times of situational anxiety or depression.

Contraindications None known
Has GRAS status. In a 2003 report, JECFA stated that the committee had “no safety concern” about isobutyl angelate, based on current intake as a food flavoring.
Adverse skin reactions In a 48 hour occlusive patch test on 50 Italian volunteers, undiluted chamomile oil produced no adverse reactions. When similarly tested at 5%, it produced one reaction in 290 eczema patients. Undiluted Roman chamomile oil was moderately irritating to rabbits, but was not irritating to mice; tested at 4% on 25 volunteers it was neither irritating nor sensitizing. It is non-phototoxic.
Urinary effect Administration of 350 mg/kg of Roman chamomile oil to rats by sc or ip injection resulted in decreases in water elimination from 93.04% to 46.85% and 28.10% of the water administered. The major constituents of this oil were butyl angelate and isoamyl angelate. Nothing meaningful can be extrapolated from the massive dose used he .
Acute toxicity Roman chamomile oil acute oral LD50 in rats >5 g/kg; acute dermal LD50 in rabbits >5 g/kg.
Antioxidant/pro-oxidant activity Roman chamomile oil showed moderate antioxidant activity as a DPPH radical scavenger and low activity in the aldehyde/carboxylic acid assay.
Carcinogenic/anticarcinogenic potential Roman chamomile oil was not mutagenic in either a Bacillus subtilis rec-assay or an Ames test. Chamomile oil significantly induced glutathione-S-transferase activity in mouse tissues. Roman chamomile oil contains no known carcinogens.
There is wide variation in the reported constituents of Roman chamomile oil, although the majority of the oil always consists of angelate and butyrate esters. On the basis of current knowledge, unlikely to present any hazard in aromatherapy.
