The context of the following conversation is Jan took her pills to the doctor so he could see which pills she was currently taking.:
Jan says So I got that bottle of pills out of the medicine cabinet and I went up to the doctor's office and I showed him!  'I have the cure', I said!.
The friend responds What do you mean by that? They don't have a cure yet..
Jan responds They do have a cure!  Our president says he has a hunch that hydroxychloroquine cures COVID-19 and if he says it, it has to be true!.
The friend responds Jan, I don't think that's accurate.  What did the doctor say when you showed him the pills and told him you had the cure?.
Jan responds He said that this is not a certified medicine!.
The friend responds Well, actually, doctors have literally decades of education and training and usually have the best interests of their patients at heart, Jan! .
