From a quick web search, it looks like aqua flora is indeed a homeopathic treatment for candida infections. In homeopathy, the active substance is so diluted that it is practically non-existent. The miniscule amount is supposed to trigger your body into fighting the condition.
Homeopathy is very controversial, as shown by a recent thread on this site. It's hard to imagine how it could possibly work, but there are some who swear by it. (Queen Elizabeth is one of them.) Me, I'm an agnostic: I don't use the stuff, but if someone wants to, they should go for it.
Live your life and love your life. It's the only one you get.
