In terms of curiosity and comparison, which claims have you seen out there that are absurd and don't make any sense?
I particularly like those based on geography and history - I think they're funny in some way. They just go like "With actives extracted from..." and complete with something very very specific like: Himalayan mountains, Antartic Ocean (?), Shangrila, El Dorado, the Moon, Tutankhamun's tomb... and so on.
Some ingredient in special? Please, share your experiences!
