What is chamomile, and what is it used for?

Chamomile is a medicinal herb that has been consumed as tea by humans since ancient times. Chamomile preparations have been commonly used for many ailments including gastrointestinal disorders, inflammation, hay fever, menstrual disorders, mouth ulcers, wounds and muscle spasms. Chamomile preparations are usually made from two common varieties, German Chamomile (Matricaria chamomilla) and Roman Chamomile (Chamaemelum nobile).

Chamomile tea is made from dried chamomile flower powder and the medicinal ingredients are extracted from the dried flowers for various preparations such as tincture, lotions and poultices. The whole plant is used to make herbal beers and chamomile essential oils are used for aromatherapy and for external use in skin care and cosmetic preparations. Inhalation of vaporized chamomile oil is believed to relieve anxiety and depression.

Chamomile plant contains volatile oils and chemical compounds such as flavonoids and terpenoids, which contribute to its medicinal properties. These phytochemicals have anti-inflammatory, antispasmodic, anti-allergic, antimicrobial, anticancer and antioxidant properties. In particular, one of the flavonoids, apigenin has anti-inflammatory effects comparable to non-steroidal anti-inflammatory drugs (NSAIDs).

Further research with randomized controlled clinical trials is required to establish chamomile’s safety and efficacy. Limited studies of chamomile show promising effects in many of the following conditions:
