Rosmarinic acid sources, health benefits and uses

Tuesday, September 19, 2017 by

Rosmarinic acid is a polyphenolic compound that was first discovered in 1958 by Italian chemists M. L. Scarpatti and and G. Oriente, who isolated and characterized it from rosemary. In addition to rosemary, rosmarinic acid naturally occurs in other herbs that are known for their culinary and medicinal use like basil and lemon balm. Rosmarinic acid itself has been noted to have antioxidant, anti-inflammatory, and anti-allergenic properties, and is believed to be one of the compounds that contribute to the medicinal potency of rosemary (the other compound being carnosic acid).

Other plants known to have rosmarinic acid include marjoram, sage, and thyme. High-purity rosmarinic acid extract and supplements can be purchased as well. Rosmarinic acid supplements are best taken during mealtimes, though as with most supplements, a number of side effects may occur. Those who experience dizziness, abdominal pains or skin irritation should stop taking these supplements immediately.

Medicinal uses for rosmarinic acid

Rosmarinic acid has been noted to act like a powerful anti-inflammatory agent; it reduces inflammation by altering messaging molecule concentrations, thus decreasing the body’s responses. Moreover, the gastrointestinal tract is capable of absorbing rosmarinic acid with ease, allowing this compound to work its beneficial effects rather quickly.

Because of its potent anti-inflammatory qualities, rosmarinic acid can curb the severity and frequency of seasonal allergies like rhinoconjunctivitis. One study found that patients who were supplemented with rosmarinic acid for a period of 21 days showed significantly reduced symptoms of rhinocojunctivitis when compared to patients who were given a placebo.

In addition, the anti-inflammatory effects of rosmarinic acid are such that this compound is being looked into as a potential remedy for chronic and acute inflammation and pain resulting from injury.

Rosmarinic acid has been observed suppressing the production of cells that bring about atopic dermatitis, a common skin disease that produces weeping and oozing plaques of itchy skin.

Rosmarinic acid has shown positive results when used to treat the following health ailments:

  • Bronchial asthma
  • Cataracts
  • Peptic ulcers
  • Rheumatoid arthritis
