Why not? If it blocks the stress hormone from entering one's system, then why wouldn't it reduce the effects that stress has on the body. And if it is available by "script," then what is its function? For what purposes would it be prescribed?

You also mention that it is important for endocrine function. Does that mean that coritsol is required to say, stress our endocrine system into working (for lack of a better way to state)?

If stress causes the overproduction of cortisol, which in turn causes other physical problems, then why would the blocking of (some of) it not help?
