Rhizophora mangle, also known as the red mangrove, is a woody, salt water-tolerant plant that grows in tropical and subtropical coastal areas throughout the world. Extracts from the bark of the red mangrove have been used in folk remedies for centuries, treating conditions such as sore throat, fungal infections, fever, tuberculosis, and many more. The bark contains several active constituents, including polyphenols, carbohydrates, fatty acids, and sterols.
