Salicin, the main component of willow bark, from which aspirin can be made, behaves more like substances that do not inhibit prostaglandins than like substances that do, and so is highly unlikely to possess this quality. As of this writing, aspirin remains the substance of choice for enhancing the action of ephedrine through an inhibition of prostaglandin biosynthesis. Q. Will I reach a weight plateau with thermogenics? A. There appears to be an upper limit to the capacity of a given amount of BAT to oxidize fatty acids. Once this limit has been reached, a person may experience a temporary decrease in further fat loss. This plateau may be achieved very quickly, or it may take weeks or months to reach it. At any rate, continued fat loss from this point will depend on the growth of new BAT. Brown adipose tissue mass will increa
