Constitutional Herbalism, as developed by herbalist Michael Moore, is holistic in nature. Instead of addressing symptoms the approach looks through each organ system of the body to see which are over functioning and which are working in deficiency. Then a custom formula is put together to help strengthen those weaknesses and thereby support the overall health of an individual. Because this is intended to work on deep, underlying patterns of physiological function, the custom formula is something that should be taken for an extended period of time-- a few months—in order to see changes.
