Related Applications
Liver Protection
The liver is the primary organ responsible for expelling and breaking down toxins entering the body. In particular, it produces bile, a detoxifying agent metabolically indispensable in breaking down fats from food. Many chemicals from nature could protect liver to help the process of detoxication.Antineoplastic
Each year, more and more people are getting cancer, especially lung and liver cancer. However, there are not enough good anti-cancer drugs. Fortunately, many herbal extracts have good antineoplastic activity. A plant-based diet can help shield you from cancer because plants are rich in anti-inflammatory and antioxidant substances that help us withstand exposure to ultraviolet radiation, air pollution and other noxious substances.Antioxidant Supplements
Antioxidants are one kind of molecules, helping to neutralize harmful free radicals which can accelerate cellular oxidation. They provide an important and solid defense against the diseases caused by oxidative stress, such as cancer, heart disease, decline in brain function, immune system and aging. Because antioxidants are capable of stabilizing or deactivating the free radicals from oxidation reactions before they attack cells.
