Abstract

Introduction: Rhododendron arboreum Sm., locally known as Pullaas (Burans), is conspicuous for its traditional use  across the globe. The present study offers a comprehensive investigation into R. arboreum Sm., commonly known  as Pullaas, integrating pharmacognostical, phytochemical, and physicochemical approaches to ensure accurate  botanical identification and support its standardization in traditional medicine. 

Materials and Methods: Classical Ayurveda texts, including commentaries and Nighantus, are the primary  data source. The published articles related to phytopharmacognosy and physicochemical parameters available in  PubMed, Google Scholar, etc., have also been referred for this review. Organoleptic and microscopic evaluations  were conducted on the flower, leaf, and bark, revealing key diagnostic markers at Rajiv Gandhi Ayurvedic College  and Hospital, Paprola. Furthermore, the study incorporated physicochemical parameter analysis, qualitative  phytochemical screening, thin layer chromatography profiling, and ultra-performance liquid chromatography to  evaluate the chemical constituents of the plant; at CSIR - IHBT, Palampur. 

Discussion and Conclusion: Organoleptic, macroscopic, and microscopic assessments were conducted on the  flower, leaf, and bark, revealing key diagnostic markers such as paracytic stomata. Phytochemical screening  confirmed the presence of key secondary metabolites. The physicochemical parameters demonstrated acceptable limits for all parameters. The integrative analysis provides a scientific foundation for the pharmacognostical  validation, quality control, and potential therapeutic use of R. arboreum Sm., contributing to the global acceptance of  Ayurvedic plant-based medicine. Thus, the present paper serves as a foundation for selecting R. arboreum Sm. from  the Himalayan region, where its rich traditional use shows promising results for the development of evidence-based  herbal formulations.
