Watercress
Nasturtium officinale
Nasturtium officinale, commonly known as watercress, originates from traditional medicine practices but has not been widely documented for specific uses. Scientific studies have shown that it possesses high DPPH radical scavenging capacity and selective prebiotic effects, indicating potential antioxidant properties. Additionally, a study found that watercress leaf methanolic extract demonstrated protective effects against colonic inflammation in rats by normalizing antioxidant enzyme activity and reducing inflammatory markers. The consumption of watercress has shown varying effects on lipid profiles and antioxidant markers among different groups, including non-smokers, smokers, and secondhand smoke-exposed individuals. No major safety issues or drug interactions have been recorded, suggesting that it is generally safe for use.
