Antioxidants are elements that can protect your cells against free radicals. Which may play a role in heart disease and cancer. When your body breaks down food or if you are exposed to radiation, free radicals are molecules produced. Which are not good for your health. Some antioxidant drugs have particular administration as neuroprotectants, serving to protect nerve cells against damage, degeneration, or impairment of function. Cannabidiol(CBD) is a powerful antioxidant which can prevent or treat diseases related to oxidative stress, such as neuronal hypoxia by administering a therapeutically effective amount of CBD to a subject that has a disease caused by oxidative stress.
