A loofah is the rough, scratchy sponge people use in the bath or shower to scrub skin. It is not a sea sponge. It is the dried, fibrous inside of a tropical gourd (the same plant family as the 絲瓜 you eat). When the fruit is dried, the soft flesh falls away and a net of tough fibres is left; that net is the loofah. Some loofahs in shops are now plastic copies of that shape; the old kind is still the plant. You can also use loofah as a verb: to scrub with one. It is an ordinary bathroom word, not medical and not slang.
絲瓜布、絲瓜絡（就是乾絲瓜瓤拿來搓身體的那種；不是海綿）
組成Borrowed from Arabic lūfa (لُوفَة). English just kept the name of the plant.
