Eating garlic every day can reduce the chances of catching a cold or shorten the duration of an illness by 70%.

In addition, eating garlic can also lower blood pressure and reduce arteriosclerosis.


Frequent colds and immune deficiencies are most likely the result of chronic inflammation. We can reduce inflammation and scavenge free radicals by consuming ginger, which has powerful antioxidant compounds like gingerol to reduce the chance of cell damage in the body.
