The genus Leucas: A review on phytochemistry and pharmacological activities.

Genus Leucas (family Lamiaceae) has been used as the traditional medicine for the treatment of a variety of disorders like skin diseases, diabetes, rheumatic pain, wounds, snake bites, etc. Several species of genus Leucas have been explored for their pharmacological activities and found to possess diverse properties like antimicrobial, antioxidant, anti-inflammatory, cytotoxic and anticancer, antinociceptive, antidiabetic, antitussive, wound healing, phytotoxic, etc. Phytochemical investigations of the different plant parts of Genus Leucas have revealed the presence of phytochemicals including terpenoids, flavonoids, lignans, phenolic glycosides, sterols, and essential oils. Terpenoids have been obtained as the major components of the isolated compounds and could be used as the marker compounds for the genus Leucas. The traditional uses of Leucas spp. have been established scientifically and were shown due to the presence of different phytochemicals. Although the pharmacological activities of Leucas plants have been well-documented, further studies are needed to fully understand their mechanisms of action and clinical applications. In conclusion, the phytochemistry and pharmacological activity of genus Leucas make it a promising source of natural products for drug discovery and development. The present review aims to provide a comprehensive note on the phytochemistry and pharmacological properties of the genus Leucas.
