Drugs do not cure disease; apparent recovery is due to nature's vital force, while drugs often shift disease form and location.

Original passage

People need to be taught that drugs do not cure disease. It is true that they sometimes afford present relief, and the patient appears to recover as the result of their use; this is because nature has sufficient vital force to expel the poison and to correct the conditions that caused the disease. Health is recovered in spite of the drug. But in most cases the drug only changes the form and location of the disease. Often the effect of the poison seems to be overcome for a time, but the results remain in the system and work great harm at some later period.
