Having healthy individuals and a society made up of healthy people is one of the most fundamental requirements for nations to survive. Treatments other than contemporary medicine in the health system should be thoroughly understood to promote healthy individuals and a healthy community. In functional medicine, nutrition is a healing-oriented health approach that also uses other medical therapy forms. Functional medicine, complementary medicine, traditional medicine, and conventional medicine all have subfields. There are various treatment approaches for these sub-areas. Patients have turned to therapeutic modalities that are not part of orthodox medicine because of a desire for a better life and an easy and affordable technique. As a result, these techniques keep getting better and better. These therapeutic approaches have advantages, but they also have drawbacks and repercussions. Many social, political, and economic processes shape societies. We occasionally favor modern medicine and occasionally alternative remedies depending on the social context we live in. These procedures, known as traditional medicine and alternative/complementary medicine, have recently sparked new debates despite maintaining their significance since antiquity. It has been made possible by factors like the lengthening of life expectancy, rise in chronic and incurable diseases, emphasis on natural remedies, decline in confidence in modern medicine and medical professionals, decline in confidence in the pharmaceutical industry, and inadequacy of modern medicine to treat some diseases.
