Research Article on Formulation and Evaluation of Herbal Bronchodilator Syrup for Asthma

Asthma is a chronic airway inflammatory disorder marked by wheezing, breathlessness, chest tightness, and coughing. While conventional treatments are effective, they often cause side effects with long-term use, highlighting the need for safer, natural alternatives. This study aims to formulate and evaluate a polyherbal bronchodilator syrup using Osmium sanctum (Tulsi), Adhatoda vasica (Vasaka), Glycyrrhiza glabra (Licorice), Zingiber officinale (Ginger), honey, and lemon juice—ingredients known for their synergistic bronchodilatory, anti-inflammatory, and soothing effects. The syrup was prepared with aqueous herbal extracts, blended with honey and lemon for taste and stability. It underwent physicochemical tests (pH, viscosity, specific gravity, microbial load), organoleptic evaluation (taste, color, odor, consistency), stability, and preliminary in vitro studies. Results showed the syrup met pharmaceutical standards and demonstrated potential as a natural bronchodilator for mild to moderate asthma, with good patient acceptability and minimal side effects. Further in vivo and clinical studies are recommended to validate its efficacy.
