Significance of Free radical scavenging activity
Free radical scavenging activity, as described across various scientific contexts, consistently refers to a substance's ability to neutralize harmful free radicals. These unstable molecules can damage cells and contribute to diseases. This neutralizing action, often exhibited by antioxidants and extracts from plants, protects cells from oxidative damage and promotes health. Various methods, like DPPH assays, are used to measure this crucial activity, which is linked to potential benefits such as wound healing and obesity treatment.

Hindu concept of 'Free radical scavenging activity'
In Hinduism, free radical scavenging activity is the ability of a substance, like certain drugs or plant extracts, to neutralize unstable molecules (free radicals). This action protects cells from damage, as demonstrated by chebulinic acid, and is linked to antioxidant effects.
