Canafistula is a term that refers to a type of tree commonly found in the Americas, particularly in the Caribbean region. Also known as Cassia fistula, canafistula is renowned for its yellow flowers and medicinal properties. However, there are several synonyms for the word canafistula, including Indian Laburnum, Golden Shower, and Purging Cassia. These names derive from the tree's bright yellow flowers, the cathartic effects of its bark and leaves, and its resemblance to the laburnum plant. Canafistula has been used in traditional medicine for centuries and is believed to have potent laxative, antipyretic, and antimicrobial properties. Its popularity continues in modern medicine, where it is used to treat constipation, fever, and other ailments.
