Before she passed my Nan had chronic arthritis. She had many joint replacements (both hips, a knee, shoulder, pins in her wrists etc) and without medication life was a misery.

One thing she said gave her genuine relief was acupuncture, and she wasn't into pseudoscience at all. Maybe is was a placebo effect and it was expensive but it was worthwhile for her.

Not sure either of these counts fully as what OP is looking for, but -

The idea of the technological singularity feels right to me. There's a whole section on the wikipedia page about scientific objections to it, and I get that, but if we don't kill ourselves before then, it seems like an event that almost has to occur at some point, to me. And maybe it zigs instead of zags and we get star trek. Or maybe it zags and we get terminator. But probably neither of those I'm guessing, and these days it's hard to imagine that it would put humanity on a worse trajectory than we seem to be on today.

Similarly, but less seriously (for me) I like to consider the whole "maybe we're in a simulation" theory.

When someone says it's quiet at work, suddenly all these emergencies come in...

Feng Shui, though I mostly credit it to the Dear Modern channel breaking the concept of qi and energy down into stuff like human traffic flow, activities, scenery, and noise, and using that to optimize spaces for comfort. It's mostly psychology, and some of the superstitious stuff I'm not really into.

Partly hollow earth. There are oceans in the crust, I think that is an accepted theory now. Life could have evolved to survive down there. It might not be anything special but a micro-organism is life too.

Osteopathy.

I thought it was scientifically proven, it seems that's not the case 😬

Acupuncture, to a certain extent. There's obviously something to it (a friend of mine went there because of various issues, and it helped), but the actual science isn't nailed down yet.

Mind-body. That you can think yourself sick, or well. Not like magic, but a lot of the time. Like how people won't get sick until vacation a lot of the time, they say "don't have time to get sick" so then on the day off, the mind tells the body "ok now you have time!". All of my kids were born on a day off or weekend, same thing in a way. And once I read a book where the protagonist' hands were burned, very vividly described, and got blisters on my fingertips.

I just really believe a lot of physical illness, and health, comes from thinking.

Goodness, that's a lot to read.

I don't know if I believe any of them with actual faith instead of just chalking coincidental things up to some beliefs like that. The Lunar phase one comes to mind as something I'll often reference, but I don't actually believe in lunacy.

However, there's one about grounding methods in the health section. I definitely don't believe there's anything about elecron alignment or whatever bull that all is. But being on the ground helps me a lot with anxiety and relaxation in general. To the point where I prefer sitting in front of my couch vs on it, lol. So maybe I believe in that one, but not in any pseudoscience way??

I like all the ones you listed and I love “woowoomancer” as a description. Other than those, I have a good feel for future sight.

ITT: very little pseudoscience. It's pseudoscience only when you try to pass something non-scientific as science (understood in the modernist sense). There are plenty of systems of knowledge that are outside of science and don't really care about passing as science when making statements about the world: metaphysics, theology, cybernetics, open systems theory, and so forth. Those are not pseudosciences.

I believe that literally every esotheric and nonesotheric bullshit is more trustworthy than everything a politician says at any given moment.
