Pharmacognostical and Pharmaceutical Evaluation of Nishaditaila - An Ayurvedic Oil Based Medicine

Background: Nishadi Taila is a Sneha Kalpana, indicated in the management of Mukharoga. Objective: Present study is aimed to look out on herbal drugs used in the preparation of Nishadi Taila and standardization of pharmacognostical, physicochemical parameters and HPTLC evaluation. Methods: Identification and authentication was done by pharmacognostical study i. e. organoleptic characters and powder microscopy. Physicochemical evaluation and HPTLC study was carried out of final product. Results: Pharmacognostical study shows starch grains, bordered pitted vessel oil globules, group of fibers oleoresins etc. are the diagnostic characters. Conclusion: Identification, Authentication of Herbal drug used in the preparation. Physicochemical evaluation has been carried out of prepared drug which is further useful for standardization of Nishadi Taila and other researches. The presence of oil globules, endosperm fragments, pollen grain cork cells were the characteristic features observed in the microscopy of drug combination. Refractive index of Nishadi Taila found 1.4820, specific gravity 0.9148, iodine value 92.68, saponification value183.41 and acid value is 6.05.
