Chamomile, like goldenseal, is an old remedy for just about anything. From stomach ulcers to insomnia, chamomile has been used as a powder, pill or liquid supplement to treat and ease common minor ailments. A member of the daisy family, chamomile is famously paired with teas, honeys, herbs and lemon and is known for its calming and relaxing effects on the body. The plant contains a flavonoid (antioxidant) that gives it relaxing properties but is included in the ragweed family of plants, so allergic reactions are a general concern when using supplements of foods containing chamomile.
