German Chamomile
Also known as: Chamomile, German Chamomile, Roman Chamomile, Chamaemelum nobile, *Matricaria chamomilla*
Overview
Chamomile is an herbal supplement derived primarily from the flowers of *Matricaria chamomilla*, commonly used in various forms such as teas, capsules, and essential oils. It is renowned for its calming effects and is often utilized to enhance sleep quality, alleviate anxiety, and address digestive issues. The herb possesses notable anti-inflammatory and antioxidant properties, and its usage is supported by moderate-level research, particularly concerning sleep improvement and effects on generalized anxiety disorder (GAD). While its effects are documented in multiple studies, further high-quality research is required to confirm and expand upon these findings, especially in therapeutic contexts.
Benefits
Chamomile offers several evidence-backed benefits. Studies indicate that it significantly improves sleep quality, with a meta-analysis showing a standardized mean difference of -0.73 supporting its use (P < 0.005). Furthermore, it has demonstrated marked efficacy in managing symptoms of generalized anxiety disorder, with improvements noted after just two to four weeks of use (mean differences = -1.43 and -1.79, P = 0.007; P = 0.0097). Though less evidence supports its role in alleviating gastrointestinal disorders and potential anti-cancer properties (through apigenin), its most notable population-specific benefits have been observed in the elderly, who experience enhanced sleep quality. Overall, the effect sizes for sleep and anxiety interventions indicate moderate clinical significance.
How it works
Chamomile's therapeutic effects are primarily attributed to its flavonoids, particularly apigenin, which interact with GABA receptors in the brain. This interaction promotes sedation and relaxation, ultimately reducing anxiety. Additionally, chamomile may influence other neurotransmitter systems, though the exact pathways are still being studied. Despite limited understanding of the bioavailability of its active compounds, it is acknowledged that these compounds are absorbed through the gastrointestinal tract.
Side effects
Chamomile is generally considered safe when consumed in typical amounts, though some users may experience mild side effects. Common adverse effects, occurring in more than 5% of users, include nausea, dizziness, and diarrhea. Less frequently, about 1-5%, individuals may report skin rashes. Rarely, allergic reactions can occur, especially in individuals with sensitivities to related plants, leading to serious complications such as anaphylaxis. Chamomile may interact with medications such as blood thinners, sedatives, and cyclosporine. It is contraindicated for those allergic to ragweed, chrysanthemums, marigolds, or daisies, and caution is advised for pregnant or breastfeeding women due to limited safety data.
Dosage
While the optimal dosage for chamomile is not firmly established, it is commonly consumed as tea or in capsule form, typically ranging from 200 to 400 mg per day for improving sleep and alleviating anxiety. It is often recommended to take chamomile before bedtime to maximize its sleep benefits. The maximum safe dosage remains ambiguous; however, it is advisable to avoid excessively high doses. The bioavailability of chamomile may also vary depending on the preparation method, highlighting the importance of understanding form-specific recommendations.
