Disease does not exist in isolation – it is harbored by an individual. Is it the germ we should try to take care of, or the person who doesn’t have the vitality to deal with the germ? There is a reason why every person doesn’t get the symptoms of flu while it’s going around, and why different people develop varied levels of intensity.
It makes sense to strengthen the individual than to attack the disease. Attacking and suppressing disease may provide temporary relief. However, the root imbalance in the person is seen to surface again, usually with increased intensity.
