Harvest the mature gourds, remove the outer skin and seeds, and dry the remaining fibrous interior thoroughly before using it as a natural sponge.
Yes, many loofah varieties are edible when harvested young and tender. Immature green fruits can be cooked in curries, stir-fries, soups, and other vegetable dishes. As the fruits mature, their internal fibers become increasingly tough and develop the familiar sponge-like structure. For eating, harvest the gourds before they become fibrous and hard. Confirm that your particular variety is intended for edible use.
