From all my course work in the study of Naturopathy I have come to learn that all degenerative disease arises from poor liver function. If the liver is healthy and functioning properly then, usually, everything else can heal as well.
However, our brain can trigger imbalance, trauma, for example, can throw off our chemical balance and disrupt the flow of vital minerals, which can in turn start the course of illness. So, in some cases it may be the brain that first initiates the course of illness.
Consider also a child born to a mother who has a congested liver. A child born to an unhealthy mother will not be any healthier than the mom. So, in this case there is inherited weakness passed on. In this case, nutrition will be vital and a positive and nurturing environment essential for the child to overcome that weakness. Most likely, this child will develop asthma, childhood illnesses and other health related complications, even if fed and treated properly in today’s world because of our environmental pollutions.
