No, I know, that's what I'm curious about, haha. I think the expedition is a red herring here.

For all my searching, I can only turn up sources that say limes are less effective than lemons, and lemons are less effective than oranges, and all citrus is less effective than fresh mammal meat, particularly liver. I can find sources that say the vitamin c breaks down when heated, so the navy's switch from fresh limes to canned lime juice made things worse around the age of the steam ship.

I cannot find sources that say limes don't work to prevent scurvy, and was wondering if you did.
