Introduction: Pinus wallichiana A.B. Jacks. or the blue pine is one of the important conifer that grows all along the Himalayan range from Afghanistan in the west to Myanmar and China in the east covering the Himalayan regions of Pakistan, Nepal and India. It is found in the upper region of the mountains and often remains associated with other gymnosperms. The plant is of immense ethnobotanical relevance and finds extensive use among the people inhabiting the mountainous region. They are primarily valued for its timber and used for construction and infrastructural purposes. Medicinally the plant is very much important. Throughout the Himalayan region the plant is used for the cure of a number of diseases including treatment of fever, cough and cold, bone fracture, healing of injury and wounds, rheumatic pain, arthritis, inflammations etc. The plant is rich in terpenoids and flavonoids all of which possess strong antioxidant properties. Methods: Extensive literature survey was made in the internet with pubmed, google scholar forming the search platform to illustrate the traditional usage of the plant among inhabitants of various regions of Himalayas. Informations of traditional usage, chemical constituents and selected pharmacological activities of the plant were pooled from available research papers to frame the review. Results and Outcome: In this review, an attempt has been made to compile the ethnobotanical usage of Pinus wallichiana, its phytochemistry and pharmacological activity highlighting its potentiality as a cheap and affordable source of drugs for the benefit of population of Indian subcontinent and adjoining areas.

Objective: Rhododendron arboreum Sm. commonly known as Burans is an important plant of the Himalayan region. It is the national flower of Nepal and state tree of Uttarakhand. The present study pertains to the pharmacognostical evaluation of R. arboreum from Uttarakhand. Methods: Macroscopy, microscopy by free hand section cutting and with the help of scanning electron microscopy (SEM) were done along with the physicochemical analysis. Preliminary phytochemical studies and fluorescence analysis was also carried out. Results: Results revealed that the leaves contain paracytic or amphiparacytic stomata in cluster form. The epidermal cells were long and spongy. The cells also contain some grooves and papillae throughout the surface. Preliminary phytochemical analysis showed the presence of different secondary metabolites like alkaloids carbohydrates, phenols, proteins, saponins, and tannins. Conclusion: R. arboreum from Uttarakhand region was investigated for its morphological and cytological characteristics with the help of scanning electron microscopy for the first time. The results provide details on the presence of several specific characters which are important for the identification of the genuine crude drug.
