Nutraceutical perspectives and value addition of phalsa (Grewia asiatica L.): A review

Phalsa (Grewia asiatica L.) is a food plant originating from Southeast Asia, and is cultivated primarily for its fruit. Phalsa fruit is consumed raw or used as a drink or food additive. Additionally, in vitro and in vivo studies have found that extracts from various parts of phalsa plants (especially the fruit) possess strong antioxidant, radioprotective, antimicrobial, antidiabetic, anti-inflammatory, anticancer, and cardio-protective properties. However, despite the identification of numerous nutritional and health benefits of phalsa, research into nutraceutical applications of the plant are somewhat limited. Therefore, the objective of this review was to explore the pharmacological, nutritional, phytochemical, and other potential uses of the phalsa plant. Recommendations for food scientists, nutritionists, and members of other allied disciplines are provided to help direct future research into the production, value addition, preservation, and phytochemical characterization of phalsa. Moreover, its potential health benefits are highlighted, along with the underlying mechanisms of action. PRACTICAL APPLICATIONS: The aim of the present review is to explore functional aspects of phalsa (Grewia asiatica L.) bioactive compounds, their role in improving health, as well as their possible application as a functional food ingredient.
