Formulation and Evaluation of A Polyherbal Cough Syrup with Potential Anti-Obesity Effects

The rising prevalence of obesity and respiratory disorders such as chronic cough necessitates the development of multifunctional, natural therapeutics with minimal side effects. Herbal medicines, known for their safety and holistic action, offer a promising alternative to synthetic drugs. This study aimed to formulate and evaluate a polyherbal cough syrup comprising Trigonella foenum-graecum (fenugreek), Cinnamomum zeylanicum (cinnamon), Ocimum sanctum (tulsi), and Mentha piperita (peppermint), with honey serving as a natural sweetener and base. The formulation was designed to provide symptomatic relief from cough and exert secondary anti-obesity effects. The herbal syrup exhibited a reddish-brown color, aromatic odor, and sweet taste. The pH was found to be 6.15, indicating compatibility with oral administration. The specific gravity was 0.0012 g/mL, and viscosity was within the acceptable range for syrups. No signs of instability or phase separation were observed. The presence of bioactive compounds such as cinnamaldehyde and saponins supports the syrup’s potential anti-obesity and antioxidant effects.
