We like to call the old loofah loofah. Luffa often grows into a prismatic or long cylindrical shape, which is interwoven with filaments. Luffa is sweet and cold. It has the effects of dredging meridians, cooling blood and detoxifying. People often use it to treat diseases such as stagnation of qi and blood and obstruction of meridians. Especially for lactating women, when the milk is blocked, you can take it with loofah stew, which can promote lactation.
