Agree with the studies, but the singular of data is not "cure" or "safe". A substance that is shown to be beneficial in general may not be beneficial for you, and may even be harmful for you.
I have a family member who cannot take various common medicines, not because of the active ingredient (which they need) but because of the inactive ones which are generally considered safe.
Conversely, it is possible for a substance which is not shown to have a general effect in a study to have an effect specifically for a person or small group of people. Discounting this and hiding behind "evidence based medicine" is not helpful.
