Cole Burris: I'm so hungry, I'd sell my Grandmother for a tic tac.
Bill Johnson: It's mating season.
Cole Burris: What so you're tellin' me there's some snake orgy going on in the jungle?
Bill Johnson: Yeah, something like that.
Cole Burris: I had this friend, who had this friend who shot documentaries, and he and his whole crew went down to the Amazon, and they were all eaten by snakes, and that's a true story.
Gordon Mitchell: Come on Cole, you knew a guy who knew a guy. That's an urban myth.
Answer: I interpreted it as "I can't support this claim the chemical will extend cell life" because she already said it was impossible. However, the way the line sounded when delivered off screen makes it seem like it was dubbed over different dialog. So someone may not have like what was initially said and had this in as a foreshadowing of her objections later in the film, or it was just a throw away line.

Nothing was stopping her from saying that before they left the United States so that is awful writing. She had no valid reason to think or expect that saying "I can't support this" would change the President and other persons minds after they saw a great presentation with images along with science research to substantiate the claim that the blood orchid flower could renew human youth like a fountain of youth. I assume by objections you mean she didn't want to continue to go through with the expedition after Ben was killed by a giant anaconda, also she gave some answer about evidence not being valid.
