High-altitude environments harbour a diverse array of plants equipped with remarkable adaptations to extreme conditions, including low oxygen levels and intense ultraviolet radiation. In India, only 20% of high-altitude medicinal plants contribute to the drug trade, revealing an untapped reservoir of diversity. Thriving in harsh climates, these plants deploy unique defence mechanisms against abiotic stresses crucial for survival. Environmental factors significantly impact secondary metabolite production, crucial for maintaining physiological functions and acting as antioxidants. Spanning countries, the high-altitude region integrates Ayurveda, Traditional Chinese Medicine, and Unani medicine into robust traditional medicine systems. High-altitude flora exhibits rich biochemical diversity and addresses major ailments contributing to drug development and ethnobotanical uses. Studies reveal compounds with therapeutic applications like Rhodiola rosea’s stress-relieving adaptogens and Artemisia annua, the source of the antimalarial drug artemisinin. These kinds of high-altitude-derived drugs show promise for infectious diseases, cardiovascular conditions, respiratory disorders, neurodegenerative diseases, inflammatory conditions, and immunomodulatory effects, providing inspiration for ongoing drug discovery. Despite their ethnobotanical importance, many high-altitude plant species face extinctions due to prolonged exploitation. Government agencies, non-governmental organizations (NGOs), and local farmers forefront conservation initiatives, employing a combination of ex situ and in situ methods. The exploration of high-altitude plants not only opens doors to innovative solutions but also expands our understanding of the intricate relationships between nature and human well-being, particularly in the realm of drug discovery.
