While spearmint has frequently been used in much the same way as peppermint, it has far less menthol, the primary active chemical constituent found in peppermint.3 It is useful in relieving intestinal gas.2 A recent study suggests that spearmint oil may be effective in inhibiting the growth of bacteria such as E. coli, Salmonella, and Staphylococcus.4
