For the record, there was zero 'ritual' involved and no bollocks mumbo-jumbo going down when I had my two NHS acupuncture sessions. I expected zero benefit and it was sold to me as quite likely to fail but 'worth a go seeing as it's free.'
I understand what you are saying, but I disagree.
The room you were in, the person doing it, the equipment, the process, you submitting yourself to the practitioner, the piercing of your body by someone else: all these are elements of a ritual. It is not just mumbo-jumbo that constitutes ritual. All medical encounters have an aspect of ritual involved- to some extent or other.
