What is rosmarinic acid powder?
Rosmarinic acid powder is a natural substance extracted from the rosemary plant. Its main component is rosmarinic acid (a water-soluble phenolic acid compound). It typically appears as a light yellow to brown or white powder with a distinctive herbal odor. It absorbs moisture easily and should be stored away from light. Rosmarinic acid is the most important active ingredient in rosemary and has strong antioxidant, anti-inflammatory, and antibacterial properties.
