Chamomile Hydroethanolic Extract
Also known as: Chamomile, German Chamomile, Roman Chamomile, Chamomile Extract, Chamomile Hydroethanolic Extract, Matricaria chamomilla
Overview
Chamomile, scientifically known as Matricaria chamomilla, is a daisy-like herb indigenous to Europe and Western Asia, widely recognized for its remarkable medicinal properties. The dried blossoms of chamomile are commonly utilized in a variety of forms, including teas, tinctures, and hydroethanolic extracts. This herb has been treasured mainly for its calming effects and is frequently employed to alleviate anxiety, promote sleep, manage digestive issues, and treat various skin conditions. The presence of diverse bioactive compounds, including flavonoids and terpenes, contributes significantly to its therapeutic potential. While the body of research on chamomile encompasses in vitro and animal studies, alongside numerous human clinical trials, it indicates promising effects for a range of health concerns, underscoring the necessity for further rigorous research to fully validate these findings.
Benefits
Chamomile hydroethanolic extract is associated with several evidence-supported health advantages. Its most prominent benefits include significant anxiolytic and sedative effects, as demonstrated by clinical studies indicating improved sleep quality and diminished anxiety levels in individuals with generalized anxiety disorder. Additional health benefits are attributed to its anti-inflammatory and antioxidant properties, which may benefit cardiovascular and gastrointestinal health. It also exhibits gastroprotective and antispasmodic effects. Moreover, its hormonal modulation properties have been noted in women with polycystic ovarian syndrome (PCOS), where chamomile extract has been linked to decreased symptoms such as hirsutism and menstrual irregularities. Populations particularly vulnerable to these benefits include those suffering from anxiety and sleep disorders, with effect sizes reported to be moderate to large in various studies.
How it works
Chamomile's therapeutic effects are primarily due to its interactions with several biological pathways, notably the modulation of the hypothalamic-pituitary-adrenal (HPA) axis, which aids in reducing stress and anxiety. Its anti-inflammatory and antioxidant effects arise from the inhibition of pro-inflammatory enzymes and the scavenging of free radicals. Key compounds, particularly apigenin and luteolin, are known to interact with GABA receptors, enhancing neurotransmission that fosters relaxation. The hydroethanolic extraction method significantly enhances the bioavailability of these beneficial constituents, establishing chamomile as an effective dietary supplement and herbal remedy.
Side effects
Chamomile is typically safe for most individuals when taken in moderation. However, there are some potential side effects, particularly for those allergic to plants in the Asteraceae family, which can lead to allergic reactions presenting as skin rashes or gastrointestinal upset (occurring in approximately 5% or more of users). Less frequent side effects may include drowsiness or dizziness (affecting around 1-5% of users). Rarely, severe allergic reactions, including anaphylaxis, may occur. Additionally, chamomile may interact with certain medications, particularly blood thinners and drugs metabolized by the cytochrome P450 enzyme system, warranting caution in individuals using anticoagulants or those with significant medical conditions. While generally safe during lactation, chamomile's effects during pregnancy are not well-studied, thereby recommending careful use under medical supervision for expectant mothers.
Dosage
The recommended dosage of chamomile hydroethanolic extract varies depending on the specific condition being addressed. For anxiety, a general dosage range of 200-400 mg per day is advised, with some reports suggesting upper limits of up to 1000 mg for those addressing sleep disorders. In cases of gastrointestinal troubles, 100-300 mg may provide relief. To enhance sleep quality, it is recommended to take chamomile approximately 30 minutes to an hour before bedtime. For managing anxiety, dosages can be distributed throughout the day as needed. Hydroethanolic extracts are favored for their enhanced absorption; however, it is recommended to take them with food to maximize bioavailability. Although there is no defined maximum safe dose, it is advisable to approach doses exceeding 1000 mg per day with caution.
