Snails are mollusks of the family Snails, with over 25000 known species worldwide. Snails are named because they have two horn like antennae on their heads when crawling. Snails have a wide variety of species and are distributed around the world. Snails like to live in dark, damp, loose, and humus rich environments. They work during the day and stay up at night, and are most afraid of direct sunlight, making them sensitive to environmental reactions. Snails mainly feed on plant-based foods, especially vegetables, fruit tree buds, and crop roots and leaves. Snails are a well-known traditional Chinese medicine with a sweet, salty, and cold taste. They have the effects of clearing heat, diuresis, detoxification, reducing swelling, relieving heat, removing phlegm, and promoting lactation.
