Help is on the way. In a research report published online in The FASEB Journal, a team of researchers has discovered a new way to make it a lot easier to go to the bathroom, especially when all other methods fail. Specifically, they have found a group of nerve ending receptors which, when stimulated, causes the bowels to pass waste, and the specific receptor needed to activate bowel clearance. Furthermore, they tested chemicals that work with those receptors, providing a blueprint for the development of new laxatives. http://www.physorg.com/news158420857.html Medicine & Health Wed, 08 Apr 2009 14:48:11 EST news158420857 Taking herbal food supplements is certainly not free of risk.
