Elderflower (Sambucus nigra flos) has been used as a flavouring agent in foods and medicinal herb since ancient Greek times. Elderflower teas and cordials are used to treat bronchitis, cough, upper respiratory infections and fever, and elderflower is widely used in combination with other herbal substances. Elderflowers are high in bioflavonoids such as quercetin, rutin, isoquercitrin, and elderflower preparations have anti-viral, anti-inflammatory, diuretic, and detoxification actions and are used as a diaphoretic for treatment of fever and chills, and as an expectorant for treatment of mild inflammation of the upper respiratory tract and symptomatic treatment of the common cold.
