Even in diseases that we feel we understand, one treatment or medication does not prove beneficial for everyone and currently the only way to find out what works for the individual is by trial and error.
A faster route to personalized medicine lies in understanding and embracing the medical philosophy of the East where the concept is that people are not all alike and that treatment should always take into account the constitutional makeup of the individual. This is the case with Indian Ayurveda, Five Element and some other styles of Chinese Acupuncture (not TCM), and Korean Sasang Constitutional Medicine (SCM).
In these systems, personalized medicine, through constitution and pulse reading, dates back centuries. In addition, SCM is very economical to implement. It is so well developed and economical, in fact, that someone doesn’t need to be seriously ill to employ it. Knowing someone’s constitution can be used to promote health, as well as prevent and cure diseases using herbs and diet.
Recent studies in Korea, looking for genetic markers for certain diseases, have shown that some markers are only seen in one of the four Sasang Constitutions. This indicates that if we know a person’s constitution we will not need to use genetic sequencing to screen them for all disease possibilities.
