Loofah is a gourd that can be harvested for its scrubby insides. This sponge can be used as a dish scrubber or a body exfoliator. To keep sanitary, store so that the loofah can dry out between uses and routinely sanitize by boiling in water, microwaving when thoroughly damp for 20 seconds, or bleaching in a 5% solution. Being that this is a plant with minimal processing, natural coloration varies and some seeds may remain. You can plant these seeds to grow your own loofah!
