It is reported that Garcinia cambogia, a component mentioned in weight loss coffee, is a rarely used medicine. In recent years, almost all Chinese medicine literatures have little research on this plant, and there is basically no research in China. Most of its efficacy has not been recognized by the authoritative departments of the state, and it is doubtful whether the chemical components in it can make everyone lose weight after taking it. Moreover, sibutramine may be added to weight loss coffee. Sibutramine is a central nervous system inhibitor, which can suppress appetite, but it has some side effects.
