The modern medical system treats the symptoms and suppresses the disease but does little to ascertain the real cause. Toxic drugs which may suppress or relieve some ailments usually have harmful side-effects. Drugs usually hinder the self-healing efforts of the body and make recovery more difficult. According to the late Sir William Osler, an eminent physician and surgeon, when drugs are used, the patient has to recover twice - once from the illness, and once from the drug. Drugs cannot cure diseases; disease continues. It is only its pattern that changes. Drugs also produce dietary deficiencies by destroying nutrients, using them up, and preventing their absorption. Moreover, the toxicity they produce occurs at a time when the body is least capable of coping with it. The power to restore health thus lies not in drugs,but in nature.

The approach of modern system is more on combative lines after the disease has set in, whereas nature cure system lays greater emphasis on preventive method and adopts measures to attain and maintain health and prevent disease. The modern medical system treats each disease as a separate entity, requiring specific drug for its cure, whereas the nature cure system treats the organism as a whole and seeks to restore harmony to the whole of the patient's being.
