placebo..nocebo..what is the difference ?

This page is a permanent link to the reply below and its nested replies. See all post replies »
A nocebo is a detrimental effect on health produced by psychological or psychosomatic factors such as negative expectations of treatment or prognosis.

A placebo can be
1. a medicine or procedure prescribed for the psychological benefit to the patient rather than for any physiological effect,
2. a substance that has no therapeutic effect, used as a control in testing new drugs,
or
3. a measure designed merely to humour or placate someone.

@hartfire both come from the brain.
@revenant Yes. Our mind-heart-body connection is so closely intertwined that in many ways it's a big mistake to think of them as separate.
On average (meaning lots of variation for specific instances), the placebo effect accounts for about 1/3 of successful healing. It's one reason why doctors appear so confident when diagnosing and prescribing.
For a drug or treatment to be truly effective, its success needs to be greater than 33% - although some therapies get passed with as low as 10% objective success.

@hartfire I would love to start a business selling chocolate and for each chocolate bar I will tell the ladies that they will lose at least 10 pounds . Will this work ?
@revenant It might be successful for a while, but eventually you'd be taken to court for fraud and you'd lose the case.

There is absolute evidence that we need zero added sugar in our diets in order to stay healthy.
Chocolate has a perfect mix of 50% sugar with 50% saturated fat, which induces cravings for more, which leads to overweight and all the health problems that go with it.

Despite the fact that placebo and nocebo effects are real, neither will stop a poison or addictive substances from doing their damage.

A 33% chance of doing something good due to a belief, cannot outweigh a 100% certainty of that same something doing harm due to its physical effects on our systems.

If in doubt, check the experiments on obesity in rats. There's also plenty of research on human diet - see Dr Michael Mosley's books. He collates all the latest proofs.
