Formulation and Evaluation of Herbal Spray Using Tephrosia purpurea

Abstract

Tephrosia purpurea (Linn.) Pers., commonly known as Sharpunkha, is a traditional medicinal plant with diverse pharmacological properties including antimicrobial, anti-inflammatory, and antioxidant activities. This research article presents the formulation and evaluation of herbal spray using Tephrosia purpurea extract. The herbal spray formulation was developed using standardized leaf extracts, appropriate carriers, and surfactants to enhance bioavailability and efficacy. Various physicochemical parameters were evaluated including pH, viscosity, particle size, spray pattern, and content uniformity. The antimicrobial activity was assessed against selected bacterial and fungal species, demonstrating significant activity (MIC range: 10-50 μg/mL). Stability studies conducted at accelerated conditions (40°C ± 2°C, 75% RH ± 5%) for three months showed acceptable stability with minimal changes in active constituents. The herbal spray exhibited promising potential for topical applications in respiratory infections and skin conditions, with improved patient compliance and targeted drug delivery.
