It doesn't matter because it is all rubbish! Seriously, Reflexology is a pseudoscience based on two false assumptions. First, the homuncular theory that parts of the body represent a 'map' of the body whole. They don't, Full stop. (Why don't you get a headache when you stub your toe?)
Second, that there are 'energy lines' - undetectable by any science - that the practitioner can control. There aren't. Full stop.
Reflexology is essentially magic masquerading as medicine. It has not basis in reality, no mechanism by which it can work, no clinical evidence that it does work.
