Development and evaluation of Talisapatradi and Vyoshadi choorna lozenges: An ayurvedic traditional formulation

In Ayurveda, Talisapatradi choorna (TPC) and Vyoshadi choorna (VSC) are commonly used medicines for cough, cold, asthma, and rhinitis. These symptoms are due to upper respiratory infections of predominantly of viral origin. Currently, there are no effective medicines except indiscriminate uses of antibiotics, local anesthetics, and pain killers. The conventional formulation of TPC and VSC is difficult to administer so an easy manufacturing lozenge formulation was developed. The phytochemical analysis was done by preliminary thin layer chromatography (TLC) derivatization studies. High-performance thin layer chromatography (HPTLC) analysis confirmed the presence of herbal actives in the lozenge formulations. The TLC analysis results showed that TPC and VSC contain phytochemicals of flavonoids, steroids and phytosterols, and alkaloids family. The herbal actives were found to be stable in the final formulation without any interference with the excipients used in the formulation. The lozenges formulated from TPC and VSC are found to be promising alternatives to traditional form for the traditional Ayurvedic preparation. Compatibility study was done using Fourier transform infrared spectroscopy and HPTLC study.
