Also known as: Chamomile, German chamomile, Matricaria chamomilla, Organic chamomile blend

Overview

Chamomile, primarily *Matricaria chamomilla*, is a flowering plant whose dried flowers are used in herbal preparations. Organic chamomile blends typically combine chamomile with other organic herbs, but chamomile itself is the main active ingredient. It is primarily used for anxiety reduction, improving sleep quality, and treating mild insomnia, as well as for gastrointestinal discomfort and mild inflammation. The mild sedative and anxiolytic effects are attributed mainly to flavonoids like apigenin, which bind to GABA receptors in the brain. Research maturity is moderate, with multiple randomized controlled trials (RCTs) and systematic reviews/meta-analyses, though many have small sample sizes or methodological limitations. Evidence is mixed but generally supports efficacy for generalized anxiety disorder (GAD) and sleep quality improvement. Effects on state anxiety and insomnia are less clear. Chamomile is available in various forms, including teas, capsules, and extracts.

Benefits

Chamomile has shown significant benefits in improving generalized anxiety disorder (GAD) symptoms after 2 and 4 weeks of treatment, with mean differences on the HAM-A scale of -1.43 (95% CI [-2.47, -0.39], p=0.007) and -1.79 (95% CI [-3.14, -0.43], p=0.0097), respectively. It also significantly improves sleep quality with a standardized mean difference (SMD) of -0.73 (95% CI [-1.23, -0.23], p<0.005). Elderly populations, postpartum women, and nursing home residents have reported improved sleep quality with chamomile supplementation. While mild anxiolytic effects on state anxiety were not statistically significant in meta-analysis (SMD = -0.15, 95% CI [-0.46, 0.16], p=0.42), the moderate effect size for sleep quality improvement (SMD ~ -0.7) suggests a clinically meaningful benefit. Improvements in anxiety and sleep are typically reported after 2 to 4 weeks of continuous supplementation.

How it works

Chamomile's flavonoid apigenin binds to benzodiazepine receptors on GABA-A receptors in the brain, enhancing inhibitory neurotransmission and producing anxiolytic and sedative effects. This interaction modulates the central nervous system via GABAergic pathways. Additionally, chamomile's anti-inflammatory and antioxidant effects may contribute to its overall calming effects. The oral bioavailability of active flavonoids is moderate, and extraction methods and formulation can affect absorption. The primary molecular target is the GABA-A receptor benzodiazepine binding site.

Side effects

Chamomile is generally safe, with mild adverse events reported. Common side effects include mild gastrointestinal discomfort and, rarely, allergic reactions. Uncommon side effects include mild skin irritation or rash. Rare side effects include severe allergic reactions in individuals allergic to ragweed or related plants. Chamomile may interact with anticoagulants (e.g., warfarin) due to mild blood-thinning effects and may have additive sedative effects with CNS depressants. Contraindications include allergy to Asteraceae/Compositae family plants. Caution is advised during pregnancy due to limited safety data. Elderly populations have tolerated chamomile well in clinical trials, but there is limited data in children and pregnant women.

Dosage

The minimum effective dose of chamomile extract is around 200 mg twice daily for sleep and anxiety benefits. Optimal dosage ranges are 200-400 mg twice daily for 2-4 weeks. There is no established maximum safe dose, but doses up to 800 mg/day have been used safely in trials. Evening dosing may optimize sleep benefits. Extract capsules standardized to apigenin or total flavonoid content are preferred for consistent dosing, as chamomile tea may have variable dosing. Fatty meals may enhance flavonoid absorption. No specific cofactors are required.
