Capparis spinosa

Capparis spinosa is a plant species utilized within various traditional medicine systems. It has been historically applied as a stimulant, diuretic, expectorant, and astringent, with uses ranging from treating gout and rheumatism to addressing hepatitis and spleen issues. Scientific evidence suggests that fruit extracts may possess antioxidant, antimicrobial, and anti-senescent properties, though these effects vary based on the extraction method. Some studies indicate that its extracellular vesicles may modulate metabolic changes in certain cells, and its gamma-sitosterol component has shown antibacterial and antibiofilm activity against MRSA. No major safety issues or notable drug interactions have been recorded.
