What is a Loofah?

Loofah is a climbing vine related to gourds and cucumbers, and sometimes called the “dishrag vine,” a reference to the sponge-like qualities of the dried fruit. Six species are in the Luffa genus, and they are widely cultivated for food and sponge uses. The loofah is the only plant source of sponge, and it has been used in bathhouses and kitchens for centuries. Traditionally cultivated in India and the Middle East, where the name originates, it is also grown in other warm, dry regions.

In appearance, a loofah looks like a cucumber. The trailing vines of the plant will take over any available surface, yielding drooping green fruit in the summer. These vines are often used to cover decaying fences or as privacy foliage, because they are dense and fast growing. Loofah prefers warm, dry climates, and is very sensitive to frost, generally not thriving outside of USDA Zone 10 unless gardeners sprout it indoors and keep a close eye on their young plants. They need to be watered regularly, but should not be allowed to become waterlogged.

Loofah is harvested for food in many parts of Asia. All species are edible, but they must be consumed before they mature, or they will be too woody and fibrous to eat. The fruit is cooked before eating, and is sometimes seen on menus as “Chinese okra.” When allowed to mature and dry on the vine, loofah can be harvested as a sponge. The woody exterior skin is peeled away, and the seeds shaken out for reseeding. The loofah sponge can be sold whole, or chopped into smaller and more manageable portions. It can also be compressed for shipping. The net of straw colored fibers will puff up again if the loofah is moistened.

Like other sponges, loofah will collect bacteria if it is kept moist and warm, an environment common to bathrooms. For this reason, many people incorporating a loofah into their beauty regimen prefer to use it as a dry exfoliating brush before bathing, or to grind it and use it in exfoliating scrubs. As a dry brush, it will gently remove the surface layer of dead skin, leaving the skin smooth and conditioned. Loofah can be used as a body sponge in the shower, but it should be allowed to dry out between uses. In the kitchen, it makes a great abrasive sponge for removing stubborn food particles from dishes and counter tops. Loofah is also gentle enough to use on delicate things like coated cookware, which cannot withstand normal abrasives.

I use a natural loofah to scrub my body once a week before showering. I don't like getting it wet, and it works great when dry.

In the summertime, the bottoms and sides of my feet get so rough. I scrub them with the loofah to remove the tough dead skin. After I shower, I put on lotion to keep my feet smooth.


@anon49896 – The washer is too rough on loofahs. I wash mine in the dishwasher instead.

It uses really hot water, so I know that the bacteria are being killed. Also, it steam dries everything, so the loofah gets dried as well as washed.

After a few runs through the dishwasher, I do need to replace my loofah. I only wash it once a month, so I can make a loofah last about three months. Loofahs are pretty cheap, so I don't mind buying a new one that often.


I always assumed that loofah products came from the sea. I thought they were a type of sea sponge. It's interesting to learn that they grow on a vine!


I didn't know you could make a facial scrub from loofah! That's a very good idea.

I think it would be cheaper to buy a big loofah and slowly grind as much up as I need at a time to use on my face than to buy a bottle of exfoliating facial scrub. I'm going to try this.


what are the long vine-like tendrils going straight down from the plant? what do they do?


can a loofah be washed in the washer and dried? Or would I be better off just to discard it and get a new one?


With care, my friend, with care.


We've got a bushel of the "gourd--looking things."

How do we harvest, dry, and use the "things?"
