Résumé
Kasa is well-defined clinical condition in Brihadtrayi, clearly correlate with cough and its pathophysiology exactly correlates with the mechanism of cough reflex in contemporary medical science. Everywhere, Paediatric Outdoor Patients Department (OPD) has more than half of the total patients having respiratory tract complaints. So, to treat the disease Kasa, Vyaghri Haritaki Avaleha (VHA) was taken from Bhaishajya Ratnavali. The present work was carried out to standardize the raw drugs & finished product-VHA with comparing API standards and previous research work done in same institute to conform its identity, quality and purity of the final product. The pharmacognostical work reveals that presence of Epidermis, Cork, Pericycle, Phloem etc. from Kantakari; Lignified fibre, Stone cells etc. of Haritaki; Aluerone grains, Prismatic crystals etc. of Shunthi observed microscopically. Organoleptic features of VHA made out of the crude drugs were within the standard range. The pH value of VHA was 4.5, Water soluble extract was 71.9 %w/w, Loss on drying was 30.41 %w/w, Reducing sugar was 27.92 %w/w and High Performance Thin Layer Chromatography (HPTLC) at 254nm and 366nm resulted into 2 & 5 spots respectively
