Nausea and vomiting are common symptoms in acute disease of all forms. If food is taken it is commonly vomited. Where vomiting does not take place, the food is likely to be thrown out by means of a diarrhea. What can be more ill-advised than to persuade a patient to take food, knowing that it will be vomited immediately? By rejecting food, does the body not indicate in the strongest possible manner, that food is not needed and cannot be used? Yet food is literally forced upon the sick patient, "by order of the physician," in spite of the fact that his whole system rebels against it, and in spite of the nausea and vomiting that follow taking it. Physicians resort to sedatives, anti-emetics and tonics in their efforts to force the rebellious digestive system into submission.
