Rating (out of 5): 2

Herbal blends or combinations have been traditionally used in various systems of medicine, such as Ayurveda, Traditional Chinese Medicine (TCM), and Western herbalism, to manage dry cough. These blends often include expectorant, demulcent, or soothing herbs like licorice root, marshmallow root, thyme, and slippery elm. The rationale is that combining herbs with different mechanisms (soothing, anti-inflammatory, antimicrobial) offers broader symptom relief. Historical texts and ethnobotanical records document the use of such mixtures to soothe irritated mucous membranes and suppress dry, non-productive coughs. However, while individual herbs within these blends may have some scientific evidence for anti-tussive or demulcent effects, clinical studies specifically evaluating herbal combinations for dry cough are limited and often lack methodological rigor. Most available evidence supporting their use is anecdotal or based on traditional practice, rather than high-quality clinical trials. Therefore, while traditional use is well established, the scientific evidence base remains modest, and efficacy may vary depending on the specific herbs and formulations used.
