The term was coined by a homeopathic doctor with he perceived intent of siloing modern scientific medication and medical study rather than attributing the legitimacy it’s earned due to the accepted rigours of the scientific process.
Not that homeopathic or Ayurvedic is not necessarily effective, but unless it’s submitted to the rigours of scientific study, it’s not science. Therefore if it passes itself off as science, it is a pseudoscience. In that case it doesn’t matter how many names anyone knows.
