Placebo's a real effect, if it works for you, great! Traditional medicine can and will quote you odds based on science for their treatments. That's because doctors are scientists and have been studying their stuff a long time. Odds are what science predicts with.
The alternative (and you could put diet/allergy treatments in there. The science is still developing) guys tend not to quote odds, it's not how they work. If your problem still wants a solution, give them a try by all means, but consider it something like going to the Casino. If it doesn't work, you don't want to be adding an unbearable cost to your woes. At least you can get the positive benefits of believing you're doing something rather than sitting and suffering.
But don't keep your MD in the dark. Some alternative cures, especially interacting with prescribed drugs, may be dangerous. She should be in the know.
