The essential oil extracted from the leaves of the spearmint plant is milder than peppermint, but still contains refreshing and aromatic qualities. Spearmint essential oil only contains 0.5% menthol compared to 40% composition in peppermint. Its uses date back thousands of years and have been documented in Ayurvedic medicine, Chinese medicine, and Greek medicine.
Spearmint essential oil is highly beneficial to one’s physical and mental health. The oil has been known to help relieve various respiratory ailments, including common colds. It is know to aid headaches or migraines, stress and, because of its mood-boosting properties, even depression. The cooling and relaxing effect of the menthol in spearmint can also help relieve spasmodic coughs, body aches, pain from muscle pulls and muscle cramps.
