Although consistent benefits have been reported there are contradictory results from different studies, possibly due to the wide variety and quality of ginseng used in the tests.   The institute is creating a longitudinal study on the effects of ginseng in clinical practice by using high quality pharmaceutical grade of Ginseng extract.  Our hypothesis is that by providing a high grade and high quality pure ginseng supplement to doctors for use in their clinical practice we would find a consistent range of therapeutic benefits for a broad range of health conditions as is found in the studies and reports of doctors through out the world.  We have established a number of study sites with health care practitioners and we are looking to consistently expand the number of study sites.
