The mangroves are coastal shrubs and trees that thrive in the saline intertidal zones of subtropical and tropical regions, playing a crucial role in protecting shorelines and supporting diverse ecosystems. Rhizophora mucronata, known as the hook mangrove, is a prominent species within the Rhizophoraceae family of true mangrove species. They are typically found in mudflats and estuaries, with resilient growth toward coastal regions. The stilt roots of Rhizophora mucronata enable it to thrive in saline seawater, providing coastal stability by preventing erosion and supporting a diverse range of birds, fish, and other organisms. Traditionally, the plant parts of Rhizophora mucronata, such as bark, root, leaves, and fruits, have been used in various cultures for their therapeutic benefits, including anti-inflammatory, anti-diabetic, and antimicrobial activities. The medicinal properties are contributed by the diverse phytocompounds like alkaloids, terpenoids, tannins, and flavonoids in the plant. The antidiarrheal, anti-diabetic, anticancer, antioxidant, anti-inflammatory, antimicrobial, and anti-cholinesterase effects are exhibited by R. mucronata in pharmacological studies. Rhizophora mucronata is gaining recognition for its fruit flour, which can help lower blood sugar levels due to its dietary water-soluble fiber. Additionally, recent US patents highlight new drug formulations derived from extracts of mangrove trees, including R. mucronata, that target viruses, fungi, bacteria, and tumors. Beyond its medicinal value, R. mucronata is also crucial for its ecological contributions, aiding in carbon sequestration and water filtration, thereby underscoring its importance in both natural and human systems.
