As with so many other health conditions, ginseng can help to strengthen the body and also flood the system with antioxidants, which are the beneficial compounds that seek out and neutralize free radicals, the dangerous byproducts of cellular respiration that can cause cellular mutation and other chronic conditions. Ginseng is also good for improving mood and lowering stress hormone levels in your body, which can exacerbate cancerous growth or put unnecessary strain on your body as it tries to fight off the disease.
