Complementary or alternative medicine can be classified into five major categories of practice:
The category names only partially describe their components. Some approaches are understandable within the concepts of modern science, whereas other approaches are not. Many types overlap with others.

Whole Medical Systems
Whole medical systems are complete systems that include a defined philosophy and explanation of disease, diagnosis, and therapy. They include the following:
Mind-Body Medicine
Mind-body techniques are based on the theory that mental and emotional factors can influence physical health. Behavioral, psychologic, social, and spiritual methods are used to preserve health and prevent or cure disease.

For example, the following techniques are used in the treatment of chronic pain, coronary artery disease, headaches, insomnia, and menopausal symptoms, and as aids during childbirth:
These techniques are also used to help people cope with disease-related and treatment-related symptoms of cancer and to prepare them for surgery.

These therapies are thought to stimulate the body’s energy and to enable toxins to leave the body. However, very little high quality research has measured how effective they are.
Energy Therapies
Energy therapies focus on the energy fields thought to exist in and around the body (biofields). These therapies also encompass the use of external energy sources (electromagnetic fields) to influence health and healing. Energy therapies are based on a core belief in the existence of a universal life force or subtle energy that resides in and around the body (vitalism). Limited scientific evidence supports the existence of such a universal life force, which is inherently hard to measure.
Energy therapies include the following:
