Science

This extract exerts its primary effects through a high concentration of polyphenols and flavonoids, acting as a powerful antioxidant and anti-inflammatory agent. It helps neutralize free radicals via naturally occurring non-enzymatic antioxidants and may enhance endogenous antioxidant enzyme activity. Research on related Sideritis species suggests potential anti-aging benefits, including inhibiting bacterial collagenase activity, reducing advanced glycation end product (AGE) formation, and mitigating ultraviolet B (UVB)-induced matrix metalloproteinase-1 (MMP-1) expression. Additionally, certain Sideritis species exhibit antimicrobial properties.

The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated SIDERITIS SYRIACA EXTRACT. However, the European Medicines Agency (EMA) recognizes Sideritis syriaca L. (as 'Sideritis herba') for traditional oral use, with no reported side effects for conditions like coughs or mild gastrointestinal discomfort. Safety data from a related species, Sideritis scardica, indicated no acute or repeated-dose oral toxicity in rats (up to 1000 mg/kg bw of a 20% v/v ethanol extract) and was non-mutagenic, generally supporting a favorable safety profile for the genus.
