Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Botanical blends have a long history of use in traditional medicine systems to address respiratory ailments, including dry coughs. Many such blends typically contain herbs like licorice root (Glycyrrhiza glabra), marshmallow root (Althaea officinalis), mullein (Verbascum thapsus), and thyme (Thymus vulgaris). In various cultures, these botanicals are believed to soothe the throat, reduce irritation, and help suppress or alleviate coughing. For example, licorice root has been used in Traditional Chinese Medicine and Ayurveda for its demulcent and anti-inflammatory properties, while marshmallow root has a long-standing use in European herbalism for its mucilage content, believed to coat and protect irritated mucous membranes.

However, while there is a substantial body of traditional use supporting these herbs for dry cough, modern scientific validation remains limited and often inconclusive. Some small studies and laboratory research suggest potential benefits—such as anti-inflammatory or soothing effects—but large-scale clinical trials are generally lacking. Therefore, the use of “Botanical Blend” for dry cough is best supported by tradition, with a modest level of evidence, but not robust scientific proof.
