However, more research is needed before it can be recommended. In this article, we will explore the origin, preparation, and key components of spearmint extract, along with scientific research supporting its potential health benefits and whether is it safe to take in.

Origin and preparation of spearmint extract

Spearmint extract is derived from the leaves of the Mentha spicata plant through methods such as steam distillation or cold pressing, producing a concentrated essence that can be used in different forms, including oils, tinctures, and powders.

Components of spearmint extract

The primary component responsible for spearmint extract‘s various benefits is its high concentration of beneficial compounds. These include:

Monoterpenes: Known as the extract’s key aromatic compounds, monoterpenes (e.g., carvone and limonene) contribute to spearmint’s distinct flavor and fragrance.

Flavonoids: These antioxidants (e.g., rosmarinic acid and hesperidin) offer protection against oxidative stress and inflammation, playing a crucial role in supporting overall health.

Phenolic acids: Contributing to the extract’s ability to combat harmful microbes, phenolic acids (e.g., caffeic acid and coumaric acid) are critical in promoting healthy immunity.

Spearmint has a high level of antioxidants, which protect the body from free radicals. Antioxidants can scavenge reactive oxygen species (ROS) through a variety of mechanisms, including hydrogen atom transfer (HAT), single electron transfer (SET) and metal chelation. Antioxidants can also reduce oxidative stress, which is associated with many chronic health conditions. This includes inflammation, aging, diabetes and heart disease. Another health benefit of spearmint extract is its ability to lower blood sugar in people with diabetes. This is because it is rich in anti-inflammatory compounds that can help reduce oxidative stress in the body, which is known to contribute to chronic diseases and illnesses.

Spearmint herb is a medicinal plant used in a variety of ailments. Spearmint extract is anti-androgenic which means that it reduces the amount of testosterone hormone in your body. This is important because it can help to keep your hormone levels in balance. The anti-androgenic properties may help women overcome hormonal issues like polycystic ovary syndrome (PCOS) and hirsutism (unwanted facial hair growth).
