In short: Japanese mint (Mentha arvensis) usually yields oil with more menthol, has larger leaves and sturdier stems, and is grown mainly for distillation. Common mints such as spearmint and hung lui have a milder aroma and are used as fresh herbs. When choosing a variety for oil, compare documented planting material, leaf yield and oil analysis rather than names alone.
