Guggul (gum guggul) is a resin produced by the mukul mirth tree. Guggulipid is extracted from guggul and contains chemicals called "plant sterols" (guggulsterones E and Z), which are believed to be active in the human body. Multiple studies published before 2003 suggested that guggul and guggulipid may lower cholesterol levels in people with high cholesterol. However, most of these trials were not well designed. More recent, well-designed research reports no improvements in cholesterol levels. In fact, small increases in "bad cholesterol" (low-density lipoprotein) are suggested. It is not clear why the results of different studies do not agree with each other. One possible explanation is that the earlier positive studies were done in India, and the later negative research is from the United States. There may be differences in these regions, such as dietary habits, that would cause different results. At this time, because of these differences in results, it remains unclear if guggul is helpful in people with high cholesterol levels or heart disease.
