Chamomile Herb Extract
Also known as: Chamomile, German chamomile, Chamomilla recutita, Matricaria recutita
Overview
Chamomile is a herb derived from the flowers of *Matricaria recutita*, commonly recognized for its calming effects. Traditionally employed in herbal medicine, it is widely used for managing anxiety, enhancing sleep quality, and addressing digestive issues. The herb contains bioactive compounds such as flavonoids (like apigenin and luteolin) and terpenoids (such as alpha-bisabolol), which contribute to its therapeutic properties. The body of research surrounding chamomile ranges from systematic reviews to meta-analyses, indicating moderate evidence for its efficacy. While many studies report significant benefits, some findings remain inconclusive, highlighting a need for further investigation into its active components and optimal application.
Benefits
Chamomile offers several evidence-based benefits: 1) **Generalized Anxiety Disorder (GAD)**: Research indicates notable improvements in GAD symptoms after 2-4 weeks of treatment, with a significant mean difference in anxiety scores (MD = -1.43, P = 0.007). 2) **Sleep Quality**: Meta-analysis results reflect a marked enhancement in sleep quality (standardized mean difference = -0.73, P < 0.005). 3) **Elderly Population**: Older adults demonstrate a particular response to chamomile, with studies suggesting beneficial effects on sleep quality. While animal studies also report anxiolytic and anti-inflammatory properties, robust human evidence remains limited, indicating moderate effect sizes for both GAD and sleep issues.
How it works
Chamomile's calming effects are believed to result from its flavonoid and terpenoid content, which may interact with GABA receptors, playing a crucial role in the regulation of anxiety and mood. This interaction activates central nervous system pathways that contribute to its sedative properties. Although robust evidence on molecular targets is still developing, the herb is noted for its potential influence on both the central nervous system and digestive system.
Side effects
Chamomile is generally regarded as safe for most individuals, although mild adverse effects can occur. Common side effects (>5% frequency) include gastrointestinal discomfort, while allergic reactions may affect sensitive individuals (1-5%). Although rare (<1%), potential side effects warrant monitoring. There is a notable risk of interactions with anticoagulants due to chamomile's mild antiplatelet properties, necessitating caution in patients on blood thinners. Furthermore, pregnant and breastfeeding women should avoid chamomile due to insufficient safety data. Individuals with allergies to the Asteraceae family should exercise special caution.
Dosage
Recommended dosages for chamomile vary; however, typical preparation forms include tea, capsules, and extracts. While a minimum effective dose has not been firmly established, many individuals find benefit from 1-2 cups of chamomile tea before bedtime for sleep support. Optimal dosages depend on individual needs and reported benefits, usually ranging up to 400-1600 mg/day of extracts. Due to the lack of specified maximal safe doses, traditional usage amounts are generally considered safe. Factors affecting absorption may include preparation methods and individual metabolic responses.
