Chamomile herb

Also known as: Matricaria chamomilla L., Chamomile, German chamomile, Hungarian chamomile, Matricaria chamomilla

Overview

Chamomile is an herb derived from the flowers of the *Matricaria chamomilla* plant, widely recognized for its calming effects and potential health benefits. It is commonly consumed as a tea, taken as a supplement, or applied topically. The herb is primarily used to improve sleep quality, reduce anxiety, and promote relaxation. Chamomile is known for its anti-inflammatory and antioxidant properties, which contribute to its therapeutic effects. Research on chamomile is considered to be at a moderate level, with several systematic reviews and meta-analyses available. While the evidence is generally of moderate quality, some studies show significant benefits, particularly in improving sleep and reducing anxiety symptoms, while others report mixed results. Chamomile's active compounds, such as apigenin and luteolin, are believed to interact with GABA receptors in the brain, contributing to its calming effects.

Benefits

Chamomile has demonstrated several evidence-based benefits. It has been shown to improve sleep quality, particularly by reducing the number of awakenings after sleep onset. Some studies indicate a significant improvement in symptoms of Generalized Anxiety Disorder (GAD) following chamomile treatment. However, results regarding its effect on general anxiety are mixed, with some studies showing no significant impact. Chamomile may also reduce oral mucositis, skin complications, depression, and vomiting in cancer patients. While promising, more research is needed to confirm these benefits, especially in specific populations like peripartum or postpartum women. The effect size for sleep quality improvement is notable, though specific numbers vary across studies. Benefits are typically observed within weeks of consistent use.

How it works

Chamomile's calming effects are primarily attributed to its active compounds, such as apigenin and luteolin, which interact with GABA receptors in the brain. This interaction promotes relaxation and reduces anxiety. Chamomile influences the nervous system by modulating neurotransmitter activity and reducing inflammation. While the exact mechanisms are still being investigated, it is believed that chamomile's compounds bind to GABA receptors, enhancing their inhibitory effects and promoting a sense of calm. The bioavailability of chamomile's active compounds is not fully understood, but they are thought to be absorbed through the gastrointestinal tract after consumption.

Side effects

Chamomile is generally considered safe when used appropriately, but it can cause side effects in some individuals. Common side effects include mild gastrointestinal disturbances. Uncommon side effects, occurring in 1-5% of users, may include allergic reactions, although these are rare. Severe allergic reactions are even rarer, affecting less than 1% of users. Chamomile may interact with blood thinners and diabetes medications, potentially altering their effects. It is contraindicated in pregnancy and breastfeeding due to limited safety data. Caution is advised for individuals with allergies to plants in the Asteraceae family, such as ragweed, chrysanthemums, marigolds, and daisies, as cross-reactivity is possible. It is important to consult with a healthcare provider before using chamomile, especially if you have any underlying health conditions or are taking medications.

Dosage

The minimum effective dose of chamomile is not well-established, and dosages vary widely depending on the form of consumption. It is often consumed as tea, with a typical preparation involving 1-2 teaspoons of dried flowers per cup. Capsules containing dried chamomile flowers are also common, with dosages ranging from 200-400 mg. The maximum safe dose is not clearly defined, so it is important to start with a lower dose and gradually increase as needed. For sleep benefits, chamomile is best taken before bedtime. The bioavailability of chamomile's active compounds may vary based on the preparation method, with tea being the traditional form and capsules offering more convenience. No specific cofactors are required for chamomile to be effective.
