Luffa gourds, often simply called luffas, are unique vegetables that transform into sponges when dried. They grow on vines and look like large, green cucumbers when fresh. Inside, they have a fibrous network that's perfect for scrubbing. People use luffas for cleaning and exfoliating their skin in baths or showers. They're also biodegradable, making them an eco-friendly choice.
Luffa gourds originate from tropical regions of Asia, particularly India and Southeast Asia. They've been used for thousands of years. Ancient Egyptians utilized luffas, as did various cultures across Asia for both cleaning and in traditional medicine. Luffas made their way to Europe and the Americas through trade routes, becoming popular in household and personal care over time.
