Significance of Free radical scavenger
A free radical scavenger refers to compounds that help neutralize harmful free radicals in the body, thereby reducing oxidative stress and preventing cellular damage. These substances, including polyphenols and flavonoids found in various herbs, play a significant role in offering antioxidant effects. They donate electrons to free radicals, effectively neutralizing their harmful impacts. Examples of these scavengers include rutin, quercetin, and gallic acid, which mitigate oxidative damage in biological systems, contributing to better overall cellular health.
