Our liver is a hard working organ in our bodies.  One of it's jobs is to filter out impurites and toxins from our blood and bodies, so that then the other elimination organs can get rid of it.  But in today's world with the number of impurities and toxins that we get exposed to on a daily basis, the liver just can't cope with it.  Toxins & impurities end up collecting in the liver causing impaired functioning of the liver, senstivities,  illness & disease.  People that have "environmental illnesses" or sensitivities to smells, perfume, detegents, or allergies, often times their liver is over loaded & clogged with impurities & toxins, therefore causing the reaction they get when exposed to more.  Cleansing the liver is so important for us to have a healthy functioning liver.  The 7 day liver cleanse is an excellent way to detox, cleanse & rejuvenate the liver back to health.  These are great detox cleanses to target specific areas for a deeper cleanse.
