it is really not that complicated and i think you misunderstand the point. proper hydration is foundational. it is not a cure, it is essential to all life and its processes. for many, this is what is missing and the problem clears when hydration is addressed. the original studies were just with water, and not that good of water either. there has been a progression to salt and then to the Sea Salt , which of course bears its own benefits. it should be ancient seabed salt mined under the ground to avoid all modern pollutants. one of the most immediate and pronounced effects i ever got from a supplement was with the ionic minerals called concentrace. i now only use real salt(brand name) and have no need of the concentrace, but i do know the effects.
dr B was able to address a variety of maladies with rehydration, all of them histimic in nature. this became so blatantly obvious for him that he determined this was the mechanism for the body to let us know of dehydration and drought. pains(including headaches and joint pains), rashes, itching, coughing, mucus in the nose and throat - all of this is a signal to hydrate. i have "cured" my children with salt and water from headaches and coughs and rashes. it just works. thats why a big glass of water works to stop hiccups. calcium isnt moving out of the esophegeal synchronizing pathways quick enough. lack of water equals lack of circulation. it is that simple.
