Not allergies or...
...ANYTHING ELSE EITHER. Reflexology
is completely bogus.
It has no basis in fact whatsoever. Reflexologists have no training in anything medical or anatomical. A reflexologist is either deluded if he believes that what he does is real, or dishonest if he knows it isn't. Think critically. "Ancient wisdom" is a myth. Seek real knowledge, not worthless quackery. Be a skeptic, not a sucker.
