A loofah is a natural sponge made from the fibrous interior of the loofah gourd, a plant belonging to the cucumber family. When the gourd is fully ripened and dried, its skin is removed, revealing a network of fibers that can be used for bathing and exfoliating the skin. Loofahs are popular in many cultures for their ability to help remove dead skin cells and improve circulation. In addition to personal care, loofahs can also be used in gardening as a natural mulch or as a biodegradable alternative to synthetic sponges. They are often found in health and beauty stores, and many people appreciate their eco-friendly qualities compared to synthetic sponges.
