Homeopathy beats Acupuncture

Well, not quite, but "[w]omen given sterile water injection experience less labour pain compared to women given acupuncture."

Sterile water injection for pain relief? Is it evidence-based? Are there like placebo-controlled trials to prove that it works?

Well, yes. Several, in fact. It's apparently a commonly-practised non-pharmacological (and non-homeopathic) method of pain relief in some places.

But if water is the substance being tested, what does one use for a placebo?

Well, believe it or not, saline*.

* - Yes, I know it makes sense. Don't write in.
