Chamomile

Chamomile (Matricaria chamomilla) is one of the best-known traditional herbs for relaxation, sleep and digestive comfort. Its flowers contain flavonoids and aromatic compounds, including apigenin, that contribute to its calming and antispasmodic properties.

It has been used for centuries in teas, extracts and herbal formulas, particularly during periods of stress, nervous tension or difficulty winding down.

Relaxation and Sleep Support

Apigenin interacts with receptors involved in calming nervous system activity, which helps explain chamomile’s traditional use before bed.

Chamomile can be useful when stress or an active mind makes relaxation difficult, and is commonly combined with herbs such as valerian, passionflower or skullcap in sleep-support formulas.

Its gentle action also makes chamomile suitable for daytime relaxation when strong sedation is not wanted.

Digestive Comfort

Chamomile has a long history of use for digestive complaints, particularly when discomfort is associated with tension or intestinal spasms.

Its antispasmodic properties can help relax smooth muscle in the digestive tract, while its naturally occurring flavonoids and essential oils provide additional soothing activity.

This connection between digestion and relaxation is one reason chamomile appears in both calming and digestive herbal preparations.

Antioxidant and Inflammatory Support

Chamomile contains several plant compounds with antioxidant and anti-inflammatory activity, including apigenin, quercetin and other flavonoids.

These compounds help support normal cellular protection and contribute to chamomile’s broader traditional use for soothing irritated tissues.

People taking anticoagulant or sedative medication should check with a healthcare professional before using concentrated chamomile supplements, particularly at higher doses.

Chamomile for Pets

Chamomile is also included in some supplements for dogs and cats to support calm behaviour, relaxation and digestive comfort.

It may be particularly useful during travel, changes in routine, noise events or periods of nervousness, and is often combined with ingredients such as L-theanine, passionflower or magnesium. Concentrated herbal products should always be given at amounts appropriate for the animal rather than using human doses.
