No, you are just not familiar with the data. There is no such thing as 'modulating biochemistry', the placebo effect is not different from no treatment at all except for the few cases I talked about. This has been throughly tested, and the conclusions are overwhelming: there is no such thing as spiritual healing or quantum healing or other such bullshit. Its all fraud and picking the few people who have happened to recover.
Even in the playlist you gave, it's mostly people who have had improvements in things like pain, irritation, scratching, stuttering. The rest is happenstance: cancers sometimes go into remission, treatments with low chance of success sometimes work and so on.
Again every time this has been studied well it has proven to be ineffective. Sometimes subjective effects are even explicitly contradicted: placebo inhalers make people with asthma feel better, but they do not in fact improve their blood oxygen levels one iota.
You have a playlist of 580 testimonials of these frauds 'helping' people. Look for such things, and see how many millions of testimonials you'll find of people who have not survived after trying to rely on 'faith healing' and 'bioenergetics' and 'eastern medicine' and so on.
Edit to add: your example of brain pattern changes in people suffering from depression on placebo treatments is again perfectly in line with known medical practices. Depression and many other psychological illnesses are well known and reported to be improved by non-pharmacological treatments such as psyhco-therapy. The gold standard in treatment of depression is a combination of psychotherapy and anti-depressants, which has been proven to be more efficient than either on its own. However, this doesn't in any way prove that psychotherapy can help with tuberculosis, as you seem to believe.
