What is health?
What is health? How do we define it? Could it be the absence of disease? Under that definition then, if we can not find anything wrong then you are considered "healthy." The drawback to that approach is that it's limited to our search criteria. Or is health like other aspects of the human condition; reading and studying increases I.Q./knowledge, exercise increases muscle and endurance, "healthy eating" increases vital body functions - decreases B.M.I. and cholesterol levels etc.?
If health is not the absence of disease then how do we measure it? What signs do we look for? What do the patterns of symptoms warn us about? It is these questions that the Eastern perspective of health is adept at measuring and answering.
For millennia the Ancients maintained their health by watching the human body respond to stimuli. They documented those observations and passed it down to the next generation for confirmation and refinement. Today we still benefit from this knowledge by identifying a pattern of disharmony. Because we can spot these patterns early on, we can gently steer them and correct them before illness, disease, and organ failure occurs. Proper identification then leads us to the best tools - herbs, foods, and exercises.
After you have identified the pattern of the concern, then you need to tools to fix it. Again, this is where an Eastern approach has much to offer. Millennia of observations provides insight into what to use for the good, better, and best solutions. Nutritional guidance and herbal formulas are two of the most powerful.
