Chamomile Extract

Also known as: Chamomile, German Chamomile, wild chamomile, chamomile tea, chamomile extract, Matricaria chamomilla L.

Overview

Chamomile is an herb derived from the flowers of Matricaria chamomilla L., commonly known as German Chamomile. It is native to Europe and Western Asia and celebrated for its medicinal properties within traditional and complementary medicine. The herb is available in various forms, including tea, capsules, and topical extracts, primarily used for its anxiolytic, sedative, and anti-inflammatory effects. The active compounds found in chamomile, such as alpha-bisabolol and azulenes, contribute to its antioxidant and anti-inflammatory properties. Current research substantiates chamomile's effectiveness in managing anxiety and sleep disturbances, supporting its favorable safety profile as a widely consumed dietary supplement.

Benefits

Chamomile offers several evidence-based benefits, particularly in managing Generalized Anxiety Disorder (GAD) and enhancing sleep quality. Meta-analyses indicate significant symptom improvements in GAD, with mean differences of -1.43 after two weeks and -1.79 after four weeks of treatment (P = 0.007 and P = 0.0097). Chamomile also promotes better sleep quality, as evidenced by reductions in Pittsburgh Sleep Quality Index scores (WMD: -1.88). Older adults, especially women of Mexican origin, experience a 33% reduction in all-cause mortality associated with chamomile intake (HR 0.67). While there are minimal effects observed on state anxiety and insomnia severity, the evidence suggests meaningful clinical benefits for targeted demographics.

How it works

Chamomile's effects are largely attributed to its active compounds, alpha-bisabolol and azulenes, which engage in various biological pathways. These compounds exhibit antioxidant, antimicrobial, and anti-inflammatory properties that support the herb's anxiolytic and sedative effects. Chamomile exerts its influence on neurotransmitter systems and inflammatory pathways in the central nervous system, enhancing the body's ability to manage stress and promote relaxation. The method of administration can impact the effectiveness and bioavailability of chamomile's components.

Side effects

Chamomile is generally considered safe, with reported adverse effects being mild and infrequent. Common side effects include skin irritation and sensitization at rates of 1-5%, particularly from topical applications. Severe adverse effects occur at a rate of less than 1%, but comprehensive data on rare side effects remains limited. Caution is recommended when combining chamomile with sedatives or anticoagulants due to potential antiplatelet interactions. Individuals with allergies to chamomile or related plants in the Asteraceae family should avoid its use. Pregnant or breastfeeding women are advised to consult healthcare professionals due to insufficient safety data in these populations.

Dosage

The typical recommended minimum effective dose for chamomile (4:1 extract) ranges from 200-400 mg daily. For specific therapeutic outcomes connected to GAD and sleep quality, clinical trials suggest a daily intake of 400-800 mg. Although an upper limit is not firmly established, dosages exceeding 800 mg per day have been less extensively studied. For optimal results in sleep enhancement, chamomile should ideally be consumed 30 minutes to 1 hour before bedtime. Common forms of supplementation include capsules and tea, with extracts providing more consistent dosing. Individual metabolic factors and the form of administration can significantly affect absorption and therapeutic efficacy.
