Moreover, ginger acts as a cardiotonic that increases the efficiency of the heart contraction and improves blood flow throughout the body (16).
Studies showed that garlic has an anti-tumor effect primarily attributed to its bioactive compounds (18, 19). Heating destroys the active compound in garlic which is responsible for its anti-cancer effects (20).
In “Iowa Women’s Health Study,” garlic was the only food out of 127 food items that showed a significant association with decreased colon cancer risk (21).

Gingerol showed to inhibit skin tumor promotion (23). Meanwhile, a study mentioned the importance of considering the application of garlic in the chemoprevention of skin cancer (24).
Antioxidants are scavengers of free radicals found in the body that protect the body from cell damage. Both ginger and garlic have antioxidant effects. However, ginger was found to have the highest antioxidant potency, followed by dry garlic and fresh garlic (25). The antioxidant capacity was comparable to that of vitamin C (25).
