Spearmint or spear mint (Mentha spicata) is a species of mint native to much of Europe and southwest Asia, though its exact natural range is uncertain due to extensive early cultivation.Spearmint is an herb. The leaves and oil are used to make medicine. Spearmint is used for digestive disorders including gas, indigestion, nausea, diarrhea, upper gastrointestinal tract spasms, irritable bowel syndrome (IBS), bile duct and gallbladder swelling (inflammation), and gallstones. It is also used for sore throat, colds, headaches, toothaches, cramps, cancer and inflammation of respiratory tract. Some people use it as a stimulant, germ-killer, local pain-killer, and anti-spasm medication. Spearmint is applied directly to the skin for swelling inside the mouth, arthritis, local muscle and nerve pain, and skin conditions including pruritus and urticaria.
