## Mechanism of Action

Capparis spinosa's flavonoids, including rutin and quercetin-3-glucoside, scavenge DPPH [free radical](/ingredients/condition/antioxidant)s with an IC₅₀ of 36.6 mg/mL and upregulate antioxidant enzymes catalase and superoxide dismutase. The plant's anti-inflammatory action involves increasing IL-4 expression while decreasing IL-17 in human peripheral blood mononuclear cells, and inhibiting LPS-induced [pro-inflammatory cytokine](/ingredients/condition/inflammation)s IL-1β, IL-12p40, IL-6, and TNF-γ. Additionally, bioactive compounds upregulate immune cell surface markers CD40, CD80, and CD86, modulating immune cell activation.

## Clinical Summary

Current evidence for Capparis spinosa comes exclusively from in vitro and animal studies, with no published human clinical trials available. Laboratory studies demonstrate that rutin-rich leaf extracts protect Caco-2 and HepG2 cells from [oxidative stress](/ingredients/condition/antioxidant) without toxicity, with experiments repeated three times using five samples per group. Animal studies in Wistar rats show [hepatoprotective](/ingredients/condition/detox) effects against paracetamol and carbon tetrachloride-induced liver damage, significantly reducing liver enzyme markers. [Antimicrobial](/ingredients/condition/immune-support) studies report 70-79% biofilm inhibition against Serratia marcescens and Pseudomonas aeruginosa at concentrations of 0.5-2 mg/mL, though human efficacy remains unestablished.
