Pharmacognostic, Phytochemical and Pharmacological Profile of Karañja [Pongamia pinnata (L.) Pierre] Leaf.

ABSTRACT: Background: Pongamia pinnata (L.) Pierre, commonly known as Karañja, is a well-documented medicinal plant in traditional systems such as Ayurveda, Siddha, and folk medicine. While the seeds and oil have been extensively explored, increasing scientific attention is being directed toward the leaves due to their rich phytochemical profile and broad pharmacological potential. This review compiles and critically analyzes available literature on the botany, phytochemistry, traditional uses, and experimentally validated biological activities of P. pinnata leaves. Materials and methods: Journals, articles and various internet publications were referred to compile the relevant information of Pongamia pinnata (L.) Pierre. Result and discussion: Most literature reports indicate that Pongamia pinnata (L.) Pierre exhibits a wide range of pharmacological activities, including anti-inflammatory, antimicrobial, antioxidant, anticancer, hepatoprotective, and wound-healing effects. However, well-designed clinical studies are still required to substantiate its therapeutic potential and its role in improving patient quality of life. This review systematically compiles and critically evaluates existing information on the botany, phytochemistry, traditional applications, and experimentally validated biological activities of P. pinnata leaves. The findings highlight the need for continued research to elucidate precise molecular mechanisms, and suggest that comprehensive future studies may facilitate the development of safe and effective therapeutic applications in modern medicine.
