Having a subtle flavor of mint thanks to the small amount of natural menthol in the leaves, spearmint was originally cultivated in the Mediterranean sea region, having been found even in ancient Egyptian ruins.
An adaptogen, it contains minerals like calcium, manganese, potassium, iron (148% of RDA), and magnesium. The leaves also are rich in vitamins and antioxidents, including a high quantity of vitamin A (135% of RDA), vitamin C, vitamin B-6 (pyridoxine), riboflavin, beta-carotene, and thiamin.
Spearmint leaf tea can used to treat minor headaches, stress, fatigue and certain respiratory problems. Further medical uses are documented at “The Power of Peppermint: 21 Health Benefits Revealed” by Dr. Mercola.
