Luffa vine. I believe many people have eaten loofah, but they don’t eat loofah vines. In fact, loofah vine can also be eaten and used as medicine. When Luffa vine is used as medicine, it can reduce phlegm and relieve cough, activate blood circulation, relieve back pain, and treat tooth decay. It can also treat irregular menstruation in women. Pull out the roots of the loofah vine, dry it in the sun and grind it into powder. Drink it with rice wine twice a day, three grams at a time, to treat kidney deficiency. It can also be eaten directly when stir-fried or cooked in hot pot. It is delicious.
