The “Butter Tree” ( <scp> <i>Diploknema butyracea</i> </scp> ) for Sustainable Food Systems and Functional Applications

<i>Diploknema butyracea</i>, also known as the Himalayan butter tree, is mainly valued for its butter-producing seeds and ecological significance. In addition to being significant for its traditional usage, it has lately gained popularity in the food, cosmetics, and pharmaceutical industries for its pharmacological and therapeutic significance. All components of the tree contain beneficial phytochemicals, including phenolics, flavonoids, ascorbic acid, and essential fatty acids, and possess bioactive properties, including anti-inflammatory, antifungal, antioxidant, and antibacterial properties. Chiuri seeds contain over 60% fat and are used to produce chiuri butter with skin-healing properties and industrial applications. Despite being culturally integrated with its economic and medicinal importance, <i>D. butyracea</i> faces challenges from deforestation and overexploitation. This plant is underexplored and not widely promoted in accordance with its worth. This review describes the physicochemical and phytochemical composition of different components of <i>D. butyracea</i>. Detailed study of literature for this review was performed using databases like PubMed, Web of Science (WOS), and Scopus. Moreover, the botanical description, ecology and distribution, processing methods, and medicinal and industrial applications are also discussed, providing insight into its potential for sustainable development in the region. This review aims to emphasize the multifaceted importance of <i>D. butyracea</i> from all the available information and encourage further exploration into its commercial importance in sustainable food systems and ecological potential.
