Rosmarinic Acid Complex

Oregano (Origanum vulgare) and other medicinal mint species have antioxidant properties which are now known to be due in large part to rosmarinic acid (RA) — a compound with proven medicinal value and well-characterized physiological functions. As an antioxidant, rosmarinic acid prevents cell damage caused by free radical reactions — reactions that are thought to be involved in inflammation, degenerative arthritis and the aging process in general. RA’s antioxidant activity is high — superior to that of vitamin E and BHT, for example.

Rosmarinic acid is categorized as a ‘plant phenolic’ and is found in a great variety of plants besides oregano and rosemary. Plants such as sanicle, gypsywort, water horehound, lemon balm, the mints, marjoram, and sage contain rosmarinic acid in large amounts — more than 3%, based on dry weight. It is thought that these plants use RA as a defense compound against pathogens and herbivores.

Because it has antimicrobial and antioxidant qualities, and because it can be produced in large quantities by extraction from easily cultivated plants, rosmarinic acid has been commercially applied to food preservation — for example, to kill pathogens in sliced meat products. These same properties, plus those of being anti-inflammatory and antiviral, make RA also of interest as a nutritional supplement. It is well absorbed from the gastrointestinal tract and from the skin.

Rosmarinic acid shows promise as a preventative for atherosclerosis (the deposition of cholesterol-rich plaques in the artery walls) because RA and other polyphenols prevent the oxidation of LDL (low density lipoprotein), and oxidized LDL is a primary instigator of plaque formation. Furthermore, this inhibition of LDL oxidation is synergistically enhanced by combining RA with certain other nutritional supplements, such as lycopene.

Existing uses of RA, and usages proposed on the basis of solid medical research, include:

  • treating bronchial asthma — as in Korea, where a high-RA herb called ‘perilla’ is used for such allergic diseases
  • preventing food poisoning — as in Japan, where perilla is used to garnish raw seafood
  • HIV therapy — RA inhibits the HIV-1 integrase enzyme
  • treatment of diseases caused or propagated by complement activation, such as rheumatoid arthritis
  • treating toxic shock syndromes
  • capillary stabilization — RA inhibits microvascular injuries
  • suppression of certain kidney diseases;
  • inhibition of gingivitis
  • treatment of peptic ulcer, arthritis, and inflammatory diseases in general
  • suppression of liver toxicity, ischaemic heart disease, cataract, cancer and poor sperm motility
  • promotion of collagen and elastin synthesis in the skin

LifeLink’s Rosmarinic Acid formulation includes Grape Seed Extract — a source of antioxidants called OPCs, which have somewhat different properties than rosmarinic acid itself. The combination should enhance the product’s anti-cancer and cardiovascular-protective actions. (See the product information for LifeLink’s Grape Seed Extract for more information.)
