Health benefits of Basil herb

  • Basil leaves hold many notable plants derived chemical compounds that are known to have disease preventing and health promoting properties.
  • Basil herb contains many polyphenolic flavonoids like orientin and vicenin. These compounds were tested in-vitro laboratory for their possible anti-oxidant protection against radiation-induced lipid per-oxidation in mouse liver.
  • Basil leaves compose of several health benefiting essential oils such as eugenol, citronellol, linalool, citral, limonene and terpineol. These compounds are known to have anti-inflammatory and anti-bacterial properties.
  • The herbs' parts are very low in calories and contain no cholesterol, but are very rich source of many essential nutrients, minerals, and vitamins that are required for optimum health.
  • Basil herb contains exceptionally high levels of beta-carotenevitamin Acryptoxanthin, lutein and zea-xanthin. These compounds help act as protective scavengers against oxygen-derived free radicals and reactive oxygen species (ROS) that play a role in aging and various disease processes.
  • Zea-xanthin, a yellow flavonoid carotenoid compound, is selectively absorbed into the retinal macula lutea where it found to filter harmful UV rays from reaching the retina. Studies suggest that common herbs, fruits, and vegetables that are rich in zea-xanthin anti-oxidant help to protect from age-related macular disease (AMRD), especially in the elderly.
  • 100 g of fresh herb leaves contain astoundingly 5275 mg or 175% of daily required doses of vitamin A.Vitamin A is known to have antioxidant properties and is essential for vision. It is also required for maintaining healthy mucus membranes and skin. Consumption of natural foods rich in vitamin-A has been found to help the body protect from lung and oral cavity cancers.
  • Vitamin K in basil is essential for many coagulant factors in the blood and plays a vital role in the bone strengthening function by helping mineralization process in the bones.

  • Basil leaves are an excellent source of iron, contains 3.17 mg/100 g of fresh leaves (about 26% of RDA). Iron, being a component of hemoglobin inside the red blood cells, determines the oxygen-carrying capacity of the blood.

Medicinal uses of basil herb

  • Basil leaves contain health benefiting essential oils such as eugenol, citronellol, linalool, citral, limonene, and terpineol. These compounds are known to have anti-inflammatory and anti-bacterial properties.
  • An important essential oil, eugenol has been found to have anti-inflammatory function by acting against the enzyme cycloxygenase (COX), which mediates inflammatory cascade in the body. This enzyme-inhibiting effect of the eugenol in basil makes it an important remedy for symptomatic relief in individuals with inflammatory health problems like rheumatoid arthritis, osteoarthritis, and inflammatory bowel conditions.
