I pulled it off the FDA website.

"It is a violation of the Federal Food, Drug and Cosmetic Act to market and sell products that claim to prevent, diagnose, treat, mitigate or cure diseases without first demonstrating to the FDA that they are safe and effective for their labeled uses. "

I asked my late-night pharmacist if they carried FDA-approved limes. She said no but the grocery store has limes.

I didn't report her.

[EDIT]

rj, you are correct about the vitamin C as a treatment and what I posted was essentially backwards. A doctor who recommended citrus for scurvy would not get in trouble. It would only be a violation if the growers or sellers of citrus made the claim that it cures scurvy. It can be used to cure scurvy but as noted above, sellers can't claim it cures scurvy unless they submit to FDA testing and approval.
