The Placebo Cure is for anyone who seeks well-being and is open to exploring the power of their mind and body to relief symptoms, self-heal, enhance performance, and grow as a human being. We cover the core experience of Western health care: taking pills. The purest version of this experience is to use pills designed to convey meaning, set expectations, and trigger healing in the absence of active ingredients – in other words, pure placebo. We’ll rethink what placebos are and how to design placebo-taking experiences that are honest, safe, and beneficial. The basic principles of this book are honesty and transparency. Enjoy this journey into the re-design of pill-taking experiences, fascinating studies, and mind-boggling hacks for complex systems. My wish is that this book helps you, that it advances placebo practice, and that it stimulates more research in this important field. Create, help others, feel better, get better, be honest, – Uwe Heiss

Zeebo® placebo pills and placebo tablets have been designed with much care. Zeebo placebos are produced at FDA registered manufacturing sites in the USA following Good Manufacturing Practice. Zeebo is halal and kosher certified.

What are Zeebo Retail Customers saying


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!!



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.


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.


I take Zeebo placebo pills for occasional headaches. Several times now I took a Zeebo and that was all that I needed.

FAQ – Honest, Pure, Branded Placebo Pills

Why Honest?

Open or honest placebos are a new concept. A person who takes an honest placebo pill knows it only contains inert ingredients. There is no deceit involved. There are several studies published on taking honest placebo in a safe setting.

Why Pure?

Historically, sugar has often been used as a filler for placebos (sugar-pills). However, sugar is somewhat of an active ingredient, so it can cause problems for people with, for example, diabetes. Fillers in pure placebo capsules are inert—they pass through the body without much interaction.

Why Branded?

Today, brands play a tremendous role in the marketing of products and services. Brands convey meaning that reaches the subconscious. Branded Zeebo placebo pills harvest the power of modern marketing to promote well-being.  Our branded Zeebo Relief pills come in the Zeebo brand color in light blue and white, with the Zeebo logo printed on the white section of the capsule. Zeebo branded capsules are unique. Zeebo is The Healing Brand.
