Western medicine and nature

When are we going to realize that the western medical practices are flawed. 
when are we going to realize that the human body works in harmony...and it's all about the balance/harmony/equilibrium between the elements (chemicals, food, weather, etc.). 

Just imagine, when we catch a common cold, the doctor (in our part of the world the physician is refereed to as a doctor) prescribes pills. 
Then we might get a relief from the cold (although there is no cure for the common cold) but our kidneys have to take the wrath of those pills.
similarly when we get cancer the doctor prescribes chemotherapy and operations. 
They cut people open and remove body parts..what about the other complications..the build up of liquids, the imbalance the operations create with the other organs and their functions, side effects and the mental state of that human being after...Do we even care about those? 

In the mist of all this, we have forgotten that we had a medical practice that solely depend on natural products. We have forgotten how to live in harmony with the nature...hmmm
