Roman Chamomile Flower Oil

Also known as: Chamaemelum nobile, Anthemis nobilis, Roman Chamomile, English Chamomile, Garden Chamomile

Overview

Roman Chamomile, scientifically known as *Chamaemelum nobile*, is a perennial herb renowned for its calming and anti-inflammatory properties. The essential oil, extracted via steam distillation from its flowers, contains over 120 volatile constituents, including terpenoids like α-bisabolol and flavonoids such as apigenin. Traditionally, it has been used in aromatherapy, topical applications, and as an oral supplement to alleviate anxiety, sleep disorders, and inflammation. While research is ongoing, current evidence suggests potential benefits in reducing anxiety when used as aromatherapy, particularly in cancer patients. Oral supplementation has shown mixed results, with some studies indicating limited efficacy for generalized anxiety and insomnia. The herb's chemical constituents contribute to its antioxidant and anti-inflammatory effects, making it a versatile natural remedy.

Benefits

The primary researched benefits of Roman Chamomile include potential anxiety reduction and anti-inflammatory effects. A 2019 meta-analysis found no significant effect of oral chamomile on generalized anxiety disorder (GAD) symptoms. However, aromatherapy massage using chamomile essential oil has shown promise in reducing anxiety levels in cancer patients over a 3-week period. Preclinical studies have demonstrated anti-inflammatory and antioxidant effects linked to its flavonoid and terpenoid content. While some suggest mild sedative effects, clinical evidence remains inconclusive. The benefits appear to be population-specific, with cancer patients potentially experiencing reduced anxiety through aromatherapy. Overall, the effect sizes for anxiety reduction are small and not consistently statistically significant, necessitating further research to validate these findings.

How it works

Roman Chamomile's mechanism of action involves several biological pathways. Flavonoids like apigenin may interact with the GABAergic system, potentially binding to benzodiazepine receptors in the brain, which could produce anxiolytic and sedative effects. Additionally, the herb's anti-inflammatory effects are attributed to the inhibition of pro-inflammatory cytokines and the reduction of oxidative stress by phenolic compounds. When applied topically or ingested, the lipophilic essential oil components are absorbed through the skin or gastrointestinal tract, while water-soluble flavonoids are bioavailable when consumed as tea or extracts. These interactions modulate the central nervous and immune systems, contributing to the herb's therapeutic effects.

Side effects

Roman Chamomile is generally considered safe when used appropriately. Common side effects are rare but may include mild allergic reactions or skin irritation with topical use. Uncommon side effects, occurring in 1-5% of users, may involve gastrointestinal upset with oral ingestion. Rare side effects include hypersensitivity reactions in individuals allergic to plants in the Asteraceae family. Drug interactions are possible, with potential additive sedative effects when combined with CNS depressants; caution is advised. Contraindications include known allergies to chamomile or related plants. Limited data exists on the use of chamomile during pregnancy and lactation, so caution is recommended. No serious adverse events have been reported in reviewed randomized controlled trials (RCTs).

Dosage

Optimal dosage ranges for Roman Chamomile vary depending on the preparation. For aromatherapy massage, essential oil doses are typically diluted to safe concentrations. Oral doses of chamomile extract have ranged from 220 mg to 1100 mg daily in studies. The maximum safe dose is not clearly defined but is generally limited by tolerability and the absence of adverse effects in clinical trials. For anxiety or sleep, dosing is often daily or nightly for several weeks. Essential oil is used for aromatherapy or topical applications (diluted), while oral extracts are often standardized for apigenin or total flavonoid content. Lipophilic essential oils are absorbed through the skin and mucosa, while flavonoids are better absorbed orally with food.

FAQs

Is Roman Chamomile Flower Oil effective for anxiety?

Meta-analyses show no significant effect for oral chamomile on generalized anxiety. However, aromatherapy massage with chamomile oil may reduce anxiety in cancer patients. More research is needed.

Is it safe to use topically or aromatically?

Yes, it is generally safe when properly diluted. Watch for allergic reactions. Perform a patch test before widespread use to check for sensitivity.

How long before effects are noticed?

Aromatherapy benefits have been observed after several weeks of consistent use. The effects of oral chamomile are less clear and may vary among individuals.

Can it improve sleep?

Current evidence does not strongly support significant improvement in insomnia symptoms with chamomile. More research is needed to confirm any potential benefits.

Are there any drug interactions?

There is a potential for additive sedation with CNS depressants. Consult a healthcare provider before use, especially if you are taking other medications.
