Rosemary (Rosmarinus officinalis)
This herb, especially the flower tops, contains antibacterial and antioxidant rosmarinic acid, plus several essential oils such as cineol, camphene, borneol, bornyl acetate, and α-pinene that are known to have anti-inflammatory, anti-fungal, and antiseptic properties.
Rosemary contains vitamin A for free radical-zapping antioxidant properties, vision protection, healthy skin and mucus membranes, and increased protection from lung and mouth cancers.
Mostly renowned for fighting infection, the vitamin C content synthesizes collagen, the protein required for optimal blood vessels, organs, skin, and bones.
Manganese, another of the more prominent minerals in rosemary, play a critical antioxidant role in the body - specifically aided by its cofactor superoxide dismutase - that is associated with lowering the risk of cancer.
Rosemary also contains iron and potassium, and there's also fiber, copper, calcium, and magnesium, an abundance of B vitamins, such as pantothenic acid, pyridoxine, riboflavin, and folates.
Ingesting large quantities of rosemary could result in stomach, intestinal irritation, and kidney damage. Rosemary's constituents, monoterpene ketones, are convulsants, and have caused seizures in large doses. Rosemary also is an abortive.
