Which herbal medicine would the nurse suggest to promote sleep?

Chamomile is well-known for its calming properties and is often recommended to promote sleep. The herb contains compounds that can bind to certain receptors in the brain, leading to a sedative effect which helps in reducing anxiety and facilitating a restful night's sleep. Traditionally, chamomile tea has been consumed before bedtime to aid sleep quality because of its gentle, soothing characteristics.

Lavender, while also commonly associated with promoting sleep, is more frequently used in aromatherapy rather than as a direct herbal remedy taken internally. Valerian root is another herb known for its sedative effects, but chamomile is often the more accessible and widely used option for those seeking to promote sleep through herbal means. Ginkgo biloba, on the other hand, is primarily used to enhance cognitive function and improve circulation, making it less relevant for sleep promotion.
