A clean snail is better than a goose. The medicinal value of snail meat should not be underestimated. Traditional Chinese medicine believes that snail meat is sweet in taste and cold in nature, which can clear away heat and promote diuresis, improve eyesight and treat jaundice, edema, stranguria, thirst, dysentery, hemorrhoids and toxic swelling. "Herbal Yan Hui" said: "Snails are drugs for relieving alcoholic fever, eliminating jaundice, clearing fire eyes and benefiting the large intestine".
