Significance of Free radical scavenger
A free radical scavenger is a substance that neutralizes unstable free radicals, which can damage cells and contribute to diseases. In Ayurveda, these substances, like those in Triphala, reduce oxidative stress by converting reactive oxygen free radicals to non-reactive products. Health Sciences highlights that these scavengers, such as Vitamin C, are essential for preventing cellular damage and oxidative stress, often found in plant extracts and antioxidants. Environmental Sciences references free radical scavengers in relation to drugs and their impact on cellular processes.

Hindu concept of 'Free radical scavenger'
In Hinduism, a "free radical scavenger" is a substance, like those in Triphala, that combats oxidative stress. They neutralize unstable free radicals, converting them into harmless products, thus protecting cells from damage and potential diseases.

The concept of Free radical scavenger in scientific sources
Free radical scavengers are substances that neutralize free radicals, preventing oxidative damage. They include antioxidants like Vitamin C and compounds found in plants, which protect cells and tissues from harm. This process is crucial for reducing oxidative stress and its associated cellular damage.
