The unripened flower buds of a Mediterranean shrub, capers provide a pungent, briny intensity and firm texture that serves as a concentrated source of protective plant secondary metabolites.
Capers are a traditional component of Mediterranean seasoning patterns, which are well-established for supporting cardiovascular health and reducing the risk of chronic diseases .81112
These flower buds are notable for their concentration of secondary metabolites, including terpenoids (aromatic compounds) and polyphenols such as quercetin and kaempferol, which contribute to the plant's defense system and unique flavor profile .812
Early research suggests that the specific compounds in capers and similar Mediterranean herbs may support vascular health and modulate neuroinflammation (inflammation in the brain), though current evidence is primarily limited to preclinical and mechanistic studies .8
