Caper

Capparis spinosa, commonly known as the pricklybark or caper bush, is a traditional plant found in various regions including parts of the Middle East and Mediterranean. Traditionally, its use has not been extensively documented; however, it has been noted for its presence in certain ecological studies. Scientific evidence suggests that Capparis spinosa fruit extracts exhibit varying degrees of cytocompatibility, antioxidant, antimicrobial, and anti-senescent activity, though these findings can depend on the specific extraction method used. The plant diversity within Rawdhat Khuraym includes Capparis spinosa, with different communities dominating in various parts during dry and wet seasons. Additionally, studies indicate that extracellular vesicles from this plant may partially attenuate epithelial-to-mesenchymal transition features in Huh7 cells by modulating lipid and metabolic changes. γ-Sitosterol extracted from Capparis spinosa has shown antibacterial, antibiofilm, and antivirulence activity against MRSA, with significant inhibition of biofilm formation and virulence factor expression. No major safety issues or recorded drug interactions have been noted for this plant.
