Natural Loofah Another one is Luffa aegyptiaca commonly known as sponge gourd. Angled loofah has some vines from top to bottom and the sponge gourd is rounded. That is why the sponge gourd is used for exfoliation. Natural loofah is collected when it is fully mature and ripe. A loofah fruit mesh gets stiff when ripe. Then the loofah mesh is extracted from the dry loofah, seeds are removed from inside, washed and dried properly, and finally cut into different pieces to use.
