Chamomile essential oil can come from German chamomile or Roman chamomile. They are different plants with different oils, so “chamomile oil” is not a complete identity.
Botanical identity
German chamomile is Matricaria chamomilla L., also sold under the synonym Matricaria recutita. Roman chamomile is Chamaemelum nobile (L.) All.
Both belong to the daisy family, but they should not be treated as interchangeable ingredients. A useful label gives the full botanical name, plant part and extraction method.
How chamomile essential oil is made
The oils are normally steam-distilled from flower heads or flowering material. German chamomile oil is often deep blue because chamazulene forms during distillation. Roman chamomile oil is usually paler and has a different chemical profile.
Colour can change with composition, processing, age and storage. It is not enough to confirm species, purity or suitability.
Tea, extract and oil are different preparations
Chamomile tea, oral extracts, creams and distilled oil contain different mixtures at different concentrations. A clinical finding for one preparation cannot be transferred automatically to another.
NCCIH’s chamomile review discusses several preparations and notes that research has not established usefulness for every promoted condition. Its safety summary also records allergic reactions and possible medicine interactions.
Aroma and traditional use
German chamomile oil is usually described as strong, herbaceous and sweet. Roman chamomile is often described as fruity, apple-like and herbaceous.
Chamomile has a long history in drinks, cosmetics and herbal preparations. That history can explain why the oil is popular, but it does not establish that inhalation treats anxiety, insomnia or another condition.
Safety
Do not swallow chamomile essential oil or use it near the eyes. Use a product formulated for skin, or follow suitable dilution instructions for the exact species and purpose.
People allergic to ragweed, chrysanthemums, marigolds, daisies or related plants may be more likely to react to chamomile. Stop after a rash, swelling or breathing symptom and seek urgent help for a severe reaction.
Check with a pharmacist or doctor before medicinal use during pregnancy, breastfeeding or alongside medicines. Do not assume guidance for chamomile tea also covers concentrated oil.
