The placebo is actually there in double-blinded tests to remove any bias and other factors related to the experiment. And no matter how good/legitimate the experiment, any measurement pretty much always causes changes.

The actual effect of the placebo is usually at most a small portion of all the factors that are measured by it. Of course this depends heavily on the experiment in question and some drugs (like psychological ones) have a higher placebo effect than others.

A lot of people seem to have the idea that the placebo effect is very big for medication outside of experiments - but most of the time it's very small to non-existing.

Considering the placebo effect (unless you think bioresonance therapy is true) cured me of several allergies, I'm pretty happy with how strong it is:)

Or your allergies just went away as you got older, and you attribute that to the placebo effect.

There are complex interactions between the nervous and immune systems.

I don't think that anything has been demonstrated regarding allergies, but I wouldn't rule out a therapeutic effect in this case. The absence of evidence is not an evidence of absence.

I must say I honestly don't know if they were allergies in the medical way. For quite some time I couldn't drink large (>1L/week) of milk while milk products were fine. I always called that an allergy and only learned much later that it's not;)

I think the therapy took around 1 month, would have been a pretty sick coincidence:)

I went from not being able to eat anything with wheat or soy lecithin to having no problem with it:)
