Healing is the process of the restoration of health from an unbalanced, diseased, damaged or unvitalized organism. The result of healing can be to cure to a health challenge, but one can grow without being cured or heal without "a cure".
The profession of nursing has been traditionally concerned with matters of healing, whereas historically the profession of medicine has been concerned with curing.
With physical damage or disease suffered by an organism, healing involves the repair of living tissue(s), organs and the biological system as a whole and resumption of (normal) functioning. Medicine includes the process by which the cell(s) in the body regenerate and repair to reduce the size of a damaged or necrotic area and replace it with new living tissue. The replacement can happen in two ways: by regeneration in which the necrotic cells are replaced by new cells that form "like" tissue as was originally there; or by repair in which injured tissue is replaced with scar tissue. Most organs will heal using a mixture of both mechanisms.
It is also referred to in the context of the grieving process.
In psychiatry and psychology, healing is the process by which neuroses and psychoses are resolved to the degree that the client is able to lead a normal or fulfilling existence without being overwhelmed by psychopathological phenomena. This process may involve psychotherapy, pharmaceutical treatment or alternative approaches such as traditional spiritual healing.
