Murraya koenigii (Curry Tree): A review of its Phytochemistry, Ethnomedicinal uses, and Pharmacology with Respect to Molecular Mechanisms

Abstract:Medicinal plants have significant therapeutic value and are a gift to humanity in pursuing healthy living. The discovery of numerous rejuvenating compounds that can stop or reduce the pathology of many diseases will be a crucial advancement in the coming years. Synthetic compounds can cause health issues and side effects, necessitating the development of molecules derived from plants and other natural resources as viable substitutes for synthetic compounds. Several plant phytochemicals and extracts have been found to have significant effects on traditional medical therapy. Murraya koenigii (M. Koenigii) is a member of the Rutaceae family, well-known in the Ayurvedic system of medicine as a therapeutically important herb of Indian origin. M. Koenigii has been used in several ancient systems of medicine, including Siddha and Unani, as a multi-potential medicinal plant. Previous research has shown that this plant's bark, roots, and leaves are abundant sources of carbazole alkaloids, which have beneficial pharmacological and biological effects. These include antioxidant, antibacterial, antidiabetic, anti-inflammatory, antihypertensive, antifungal, antiprotozoal, hepatoprotective, antihypercholesterolemic, antiulcer, cytotoxic, antidiarrheal, phagocytic, neuroprotective, and antitumor activities. The key components of the M. koenigii plant and their pharmacological activities against various diseases using preclinical models are discussed in this review. Exhaustive studies on the molecular mechanism of action of M. koenigii are needed to validate the effectiveness of curry tree and their constituents as potent therapeutic agents. However, serious efforts are required to identify, isolate and evaluate the chemical components for nutritional and medicinal potentials.
