Ginger, if one encounters a statement that says something like, ‘uridine was used to suppress x-toxicity that leads to y-disease … ,’ is it correct to select a relationship that says uridine can treat y-disease, regardless of whether or not uridine is a drug? (That’s what I did, but it was a minority response as most respondents said uridine was not a drug concept.) It seems like something that shows treatment efficacy should be considered a drug concept, whether or not it’s normally considered a drug, but I might be wrong.
