There are some challenging theoretical critiques of Western medicine, such as Jon Jureidini and Leeman B. McHenry, The Illusion of Evidence-Base Medicine (2020) and Medical Nihilism (2018), by Jacob Stegenga. However, here is a great summary of all that is wrong with modern medicine by Roosh v, who has had a life a bit like St Augustine, moving from promiscuity, to finding Christ. And that is his main point, that medicine once was based around Christ, with many hospitals being set up by churches, but now have moved to secular humanism and Marxist materialism. No good has come from this, and indeed much evil.
