The Health Benefits of Spearmint
Respiratory Health: Staying in the same region of the body, spearmint tea has a significant impact on the health of your respiratory system due to its naturally soothing and anti-inflammatory qualities. It can help to relieve sore throats and tightness in the chest, alleviating congestion and irritation. Spearmint’s powerful aroma can also help to clear up sinuses and even increase mental clarity, according to certain experts.
Digestion: Spearmint has a number of roles to play in the digestive system, particularly as a gentle tonic to ease upset stomachs. It is popular during pregnancy to prevent morning sickness, nausea, and vomiting, but can also be used by others suffering from such gastrointestinal issues as excess flatulence, cramping, or bloating. IBS (Irritable Bowel Syndrome) seems to be increasing in recent years, and spearmint tea or chewing directly on spearmint leaves is often recommended to treat or manage that condition more effectively.
Hormonal Balance: For those suffering from polycystic ovary syndrome or some other form of hormonal imbalance, spearmint has been shown to help manage or treat the condition. The powerful organic compounds in spearmint can inhibit and stimulate the endocrine system in different ways, helping to optimize your hormonal balance and preventing the complicated metabolic side effects, including hirsutism, by reducing excessive testosterone levels in females.
Circulation: The iron content in a single serving of spearmint is more than 100% of the daily recommended amount, which can stimulate the production of red blood cells and hemoglobin. This not only prevents anemia but also increases circulation to the body’s extremities, boosting energy levels and wound healing.
Heart Health: The high potassium levels found in spearmint are crucial to maintaining healthy blood pressure; potassium is a vasodilator, meaning that it relieves the stress on blood vessels and arteries, therefore helping to prevent atherosclerosis, strokes, and heart attacks.
Stress Relief: Menthol, one of the most powerful active ingredients in spearmint, has a soothing, almost sedative effect on the body, which has been known to produce a calm, relaxed state. If you suffer from chronic stress or anxiety, a cup of spearmint tea can help to ease your mind and eliminate the negative effects of chronic stress hormones on your body’s systems.
Chronic Disease: Some of the other chemical compounds found in spearmint include limonene, cineole, pinene, vitamin A, vitamin C, riboflavin, and thiamin. The combination of antioxidant compounds with metabolism-balancing substances makes spearmint a powerful tool to prevent chronic diseases, including cancer, many of which are caused by free radicals attacking healthy cells. Antioxidants neutralize these free radicals and eliminate them from the body.
A Final Word of Warning: Some individuals are highly sensitive to mint and may experience allergic reactions when touching or consuming the herb. While these reactions are usually mild (skin rash, throat irritation, headache, or dizziness) it is still best to avoid this herb if you do suffer from the allergy and find other natural remedies for your various health concerns.
