Protocatechuic acid (PCA) is a type of phenolic acid, a powerful plant compound found in many common foods and traditional medicines. Its pharmacological actions have been shown to include strong antioxidant and anti-inflammatory activity in numerous studies.

Gallic acid is one of the most abundant phenolic acids in the plant kingdom, found either freely or as part of complex tannins. This ubiquity means that many common and lesser-known plants contain gallic acid, making it a regular part of a balanced diet for many people.
