The NHS is currently funding homeopathic 'medicine' and that's as about as bullshit and this total piece of crap. The idea that to make a sleeping pill you take something that keeps you awake like an extract from caffeine, then water it down to the point that there's actually more fecal matter left in the water than the caffeine extract, an then they sell it as 'natural, herbal medicine'.
The video shows two people who are so totally into this thing and are incredibly bias towards it, so they'll make their experiment look like it really works. The non-band tests remind me of this video:
It's all well and good to say it's only the placebo effect and if it works it works, but what about the 80 year old woman who is suffering so badly from arthritis freezes to death because she had to stop paying her heating bill because she bought a $140 wristband.
Or the kid who's ill from meningitis who's mother is giving him homeopathic medicine for it.
Science doesn't need to come up with anything to show that these don't work. It's the person who's making the claim that these work who has to show that they do indeed work. I bet if there was ever a double blind study done on them, it would fail so badly, but people will still buy them anyway.
