Luffa is a genus of tropical and subtropical vines in the cucumber (Cucurbitaceae) family.
In everyday non-technical usage, the luffa, also spelled loofah, usually means the fruit of the two species L. aegyptiaca and L. acutangula. The fruit of these species is cultivated and eaten as a vegetable. The fruit must be harvested at a young stage of development to be edible. The vegetable is popular in China and Vietnam. When the fruit is fully ripened, it is very fibrous. The fully developed fruit is the source of the loofah scrubbing sponge which is used in bathrooms and kitchens. Luffa are not frost-hardy, and require 150 to 200 warm days to mature.
The name luffa was taken by European botanists in the 17th century from the Egyptian Arabic name لوف lūf.
The fruit section of L. aegyptiaca may be allowed to mature and used as a bath or kitchen sponge after being processed to remove everything but the network of xylem fibers. If the loofah is allowed to fully ripen and then dry out on the vine, the flesh disappears leaving only the fibrous skeleton and seeds, which can be easily shaken out. Marketed as luffa or loofah, the sponge is used as a body scrub.
In Paraguay, panels are made out of luffa combined with other vegetable matter and recycled plastic. These can be used to create furniture and construct houses.
Luffa are best eaten when small (less than 12 cm in length) and still green.
In Vietnam, the gourd is called "mướp hương" and is a common ingredient in soups and stir-fried dishes.
In Tamil Nadu, the gourd is called Peerkangai and used as a vegetable to make Peerkangai kootu, poriyal, thogayal. Even the skin is used to make chutney.
In Karnataka's Malenadu (Western Ghats) it is known as tuppadahirekayi, which literally translates as "buttersquash". It grows naturally in this region and is consumed when it is still tender and green. It used as a vegetable in curries, but also as a snack, bhajji, dipped in chickpea batter and deep fried. Once the fruit dries out, it is used as a natural scrubber and washing sponge.
