Spearmint is a Carminative stimulant, with an affinity for the digestive, liver, lungs, nervous and endocrine systems. 
Spearmint is great at clearing excess heat, and it is more gentle than peppermint in that regard. Being a stimulating herb, this means it encourages qi stimulation. 
It is mostly cooling, slightly warming and can help with excess without slowing down the digestive process. 
It can bring crisp clarity and the ability to make heart led decisions from a calm, collected place.
