Short-Term Low Back Pain Relief with Placebo
“Over three weeks, patients with long-term low back pain who knowingly took placebo twice a day reported less pain and disability than those continuing with treatment as usual. This is not the only study to show the benefit of placebo. Whether the benefit persists is not known. A nonprescription placebo (Zeebo) is available, or pharmacists can prepare placebo capsules. (Level of Evidence = 2b)”

I have to admit that … I really didn’t believe in Zeebo placebo pills… So after a few days I was surprised to realize that it was actually working for me!!
Gail
I used Zeebo to draw my attention to healthy eating habits. Taking the pill and logging it in the app distracted me from mindless eating.
Bill
A big part of ridding ourselves of our ailments is to take control over them. Zeebo is kind of weird, but in a mysterious way, empowering.
Tony
I take Zeebo placebo pills for occasional headaches. Several times now I took a Zeebo and that was all that I needed.

We’ll rethink what placebos are and how to design placebo-taking experiences that are honest, safe, and beneficial.
