Spearmint, also known as Mentha viridis, is a plant of the Lamiaceae family. It has tonic, antiseptic, anesthetic, refreshing, decongestant, digestive and carminative properties. The spearmint is therefore useful to treat bronchitis, catarrh, flatulence and digestive problems but also joint pain and joint stiffness. The latter application is demonstrated by a Canadian study published in December 2014 on the scientific Journal of Medicinal Food. Thank to these properties a brew of spearmint is therefore useful to decongest the respiratory tract and to fight intestinal fermentation, but it can be helpful to reduce pain and stiffness in the joints affected by arthritis, too. The herbal tea is prepared in this way: boil a little more than a cup of water, remove it from heat and leave to brew 2 teaspoons of dried spearmint for ten minutes. Filter and drink.
