Hi dmsqlc1121,
Lets compare the conclusion with your alternative.

But I still think that it would have been clearer to select (A) over other answer choices if the "should always be allowed" was replaced with something like "should always select herbal remedies over conventional medicines."
Yours is much stronger. But do we need to make the conclusion stronger in order for answer choice (A) to undermine the argument? I don't think so. If answer choice (A) would undermine the weaker conclusion, then it naturally would weaken your stronger conclusion as well.
Can we think of a reason why advocates of herbal remedies should not be allowed to prescribe herbal remedies knowing that herbal remedies have little firm evidence of their effectiveness? Sure, suppose you have two medical options: the first is effective, the second is not effective. If choosing the second option would deter you from also choosing the first, then the second option should not be prescribed.
Answer choice (A) gives a clear reason why one wouldn't want to permit advocates of herbal remedies from prescribing such herbs, since they reduce the likelihood that one would consume an effective remedy.
Hope that helps!
