When looking at health and the individual as a whole rather than part by describes?

The term you are looking for is holistic when looking at health and the individual as a whole rather than part by part or as a series of separate systems.

A holistic approach to health considers the whole person, including their physical, mental, emotional, and spiritual well-being. It recognizes that all of these aspects of a person's life are interconnected and that they all contribute to their overall health.

Holistic medicine is based on the belief that the body has the ability to heal itself, and that the best way to promote healing is to support the body's natural processes. Holistic practitioners use a variety of methods to do this, including nutrition, herbal medicine, massage therapy, and acupuncture.
