Description
Luffa, also known as sponge gourd or loofah, is a plant species belonging to the Cucurbitaceae family. It is a vine that produces long, cylindrical fruit, which can be harvested and used in a variety of ways. The fruit can be eaten when young, but it is more commonly used when matured and dried out. When dried, the fibrous interior of the fruit can be used as a natural sponge for cleaning and exfoliating the skin. Luffa is native to Asia, but it is now widely cultivated in tropical and subtropical regions around the world.
