1、 Leaf difference

Huoxiang is also known as "big leaf MINT". It can be clearly seen from this alias that the leaves of Huoxiang are larger than those of mint

In addition to the size of the leaf base, you can also see the part connected with the leaf base. The leaf base of Huoxiang is "heart-shaped", and the gap of the heart is relatively shallow. The leaf base of peppermint is wedge-shaped, or nearly circular, that is, there is no "heart" shaped small gap. In addition, the leaves of patchouli look wrinkled, while the leaves of mint are smoother

2、 Flower difference

Although both patchouli and peppermint are cymose with many flowers, there are still obvious differences. The growing part of the flower of patchouli is at the "top" of the main stem or lateral branches, which is called "terminal" in Botany, and the flowers of patchouli are dense in cylindrical spikes. Peppermint flowers grow in the place where the leaves connect with the main stem, that is, "axillary". In short, the flowers of Huoxiang grow on the "top of the head", while the thin lotus grows under the "armpit"
