Use mental healing, screw the placebo, you don't even need placebo pills. Vitamins are the only pills you really need.
If i have a stomach ache, i just understand and review that im fully in control of my body. Every single part.
So then i choose to be feeling good, and my subconscious will take over.
Really, learn about the subconscious mind, if you know how to harness it, it basically puts the Law of Attraction on steroids.
