Which herbal supplement is known for promoting relaxation and improving sleep onset?

Chamomile is widely recognized for its calming effects, which can promote relaxation and improve sleep onset. It contains apigenin, an antioxidant that binds to specific receptors in the brain, leading to a sedative effect that may help reduce anxiety and facilitate sleep. This makes chamomile a popular choice as a natural remedy for insomnia and stress relief, often consumed in tea form before bedtime for its soothing properties.

In contrast, ginseng is typically associated with boosting energy and reducing fatigue, making it less suitable for promoting relaxation or sleep. St. John's Wort is primarily known for its use in treating mild to moderate depression and may interact with various medications, which can complicate its use regarding sleep. Ginkgo Biloba is often used to enhance cognitive function and improve circulation but is not directly linked to enhancing sleep or relaxation. Thus, chamomile stands out as the most appropriate choice for those seeking an herbal supplement for relaxation and improving sleep onset.
