You sound like you are referring to Vioxx or buying into the conspiracy theorists' ideas that spring from the fringe left of the political spectrum. There are many reasons for high drug prices, we can get into that discussion in anothe post, in another forum, if that is what you want to do. Medical evidence is a complicated and difficult process to evaluate, and recommendations, as you alluded to, do change with time. However, there is no "grand conspiracy" as touted by some of the sinisters who want you to purchase their products. Turning from large, multicenter RCTs to localized animal trials, non prospective, non randomized to herbal products whose efficacy and safety isn't proven is NOT the way to go if you are dissatisfied iwth the current state of affairs. In fact, you are making matters worse.
