COMPREHENSIVE REVIEW STUDY ON APRAJITA CLITORIA TERNATEA L.

Clitoria ternatea, commonly known as Aprajita or Butterfly Pea, is a perennial medicinal herb belonging to the Fabaceae family and is widely distributed throughout tropical and subtropical regions. The plant has been extensively utilized in traditional systems of medicine such as Ayurveda, Siddha, and Unani for the management of various diseases and health disorders. Owing to its remarkable therapeutic value and diverse pharmacological properties, Aprajita has gained increasing scientific attention in recent years. Different parts of the plant including flowers, roots, leaves, stems, and seeds are reported to possess medicinal importance and are traditionally used in the treatment of neurological disorders, skin infections, inflammation, respiratory diseases, urinary disorders, fever, and digestive problems. The present review provides a comprehensive overview of the botanical profile, phytochemical constituents, traditional uses, pharmacological activities, and therapeutic potential of Clitoria ternatea. Phytochemical investigations have revealed the presence of several biologically active compounds such as flavonoids, anthocyanins, alkaloids, tannins, glycosides, saponins, triterpenoids, phenolic compounds, and steroids. Among these constituents, anthocyanins known as ternatins are primarily responsible for the characteristic blue coloration of the flowers and contribute significantly to the antioxidant potential of the plant. Experimental and pharmacological studies have demonstrated that Aprajita exhibits a wide range of biological activities including antioxidant, antimicrobial, anti-inflammatory, antidiabetic, hepatoprotective, neuroprotective, analgesic, antipyretic, anticancer, immunomodulatory, and wound-healing properties. The antioxidant activity of the plant helps in neutralizing free radicals and reducing oxidative stress associated with chronic diseases and aging. Antimicrobial studies have reported inhibitory effects against several pathogenic bacteria and fungi, supporting its traditional use in skin infections and wound management. Anti-inflammatory and analgesic activities of the plant contribute to its usefulness in relieving pain, swelling, and inflammatory conditions. Aprajita is also widely recognized as a brain tonic in traditional medicine due to its memory-enhancing and neuroprotective effects. Several studies suggest that the plant may improve learning ability, cognitive performance, and mental health by protecting neuronal cells from oxidative damage. In addition, antidiabetic investigations indicate that plant extracts may assist in lowering blood glucose levels and improving glucose metabolism. Hepatoprotective studies further demonstrate its ability to protect liver tissues against toxin-induced damage. Apart from medicinal applications, the natural blue pigment obtained from the flowers has gained importance in food, cosmetic, and nutraceutical industries as a natural coloring agent. Herbal teas and functional beverages prepared from the flowers are increasingly popular because of their health-promoting properties and antioxidant content. Although numerous preclinical studies support the therapeutic potential of Clitoria ternatea, further clinical investigations, toxicity evaluations, and standardization studies are necessary to confirm its safety, efficacy, and therapeutic applications in modern healthcare systems. Overall, the plant represents a promising source of bioactive compounds with significant pharmaceutical and industrial potential, highlighting its importance in herbal medicine and future drug development research.
