Dr David Olarsch has spent 20 years helping patients who were told there was no hope.

Many of our patients have tried conventional medicine unsuccessfully. By using the Naturopathic Principles, the Institute of Naturopathic Health has been able to turn around terminal cancer diagnoses, identify mysterious illnesses, and reduce chronic symptoms of pain and inflammation.

“The doctor of the future will give no medicine, but will interest his patient in the care of the human frame, in diet and in the cause and prevention of disease.”

Called Iris Diagnosis in Europe, it is a valuable technique to facilitate a more complete under­standing of the patient’s health care needs. Iridology provides an early warning of weak­nesses in the body and is a non-invasive procedure. It is a powerful tool for health rejuvenation and preventive health care.

1 – What Is Naturopathic Medicine?

Naturopathic medicine integrates alternative medical practices—such as botanical medicine, homeopathy, acupuncture, and oriental medicine—with modern scientific diagnostic methods and standards of care.

2 – Are Naturopaths Certified Doctors?

Naturopathic doctors (N.D.s) are trained in conventional medical disciplines as well as in alternative approaches. They integrate this knowledge according to principles that recognize the body’s inherent ability to heal itself, the importance of prevention, and the possibility of therapeutic use of nutrition to promote health and fight disease.

3 – Where Did Naturopathy Come From?

Naturopathy was founded in the beginning of the 20th century by a group of therapists who were followers of Sebastian Kneipp, a 19th-century proponent of the healing powers of nature. At the height of its popularity, there were more than 20 naturopathic medical schools in the United States and naturopathic physicians were licensed in most states. The practice of naturopathic medicine declined as the use of pharmaceutical drugs increased. However, in the past several decades there has been a resurgence of interest in naturopathy. Now there are over half a dozen naturopathic medical schools in North America and many States are licensing naturopathic doctors again.
