Hi, I have looked at the sites you pointed to and I reckon that it in most likelihood it is a scam.
If you are concerned about your health and getting your body hydrated properly then I have set out below a method of hydration that I have used for some months now and I can tell you that it works wonderfully and is based on standard chemistry, how much more basic can it get than salt and water?
I am diabetic and was always thirsty, I drank plenty of water but didn't know of the need to add salt to it for it to be effective for hydration (also it makes it more palatable)
Here is what you do:
When you get up in the morning, take a 2 litre jug and fill it with tap or filtered tap water if ithe tap water tastes disgusting, then get a measuring spoon and place half a teaspoon of (100% natural, no anti-caking agents etc) Sea Salt into it and stir it well, take two 8oz (2 x 250ml) glasses of this right away, drink it down fast not sip it over time, and then about half an hour later have a proper breakfast, follow this about two and a half hours later with another glass of this special water, then get yourself out of the house and if you can, walk about 1-2 miles in the open air.
If you take this Water Cure (8 eight Oz of water/salt) each day and get the air/exercise, in about 1 week you will notice a great change in yourself and after about 4 weeks your energy and vitality will have improved dramatically and any depressive tendencies will disappear.
there is only 1 caveat, you MUST cut out ALL coffee and alcohol also soda's especially caffeineated ones.
(Caffeine and alcohol are diuretics, causing dehydration)
You will be delighted with the change in your wellbeing.
Another thing I have found that was a contributing cause of my diabetes was Monosodium Glutamate = MSG = E621 it can cause rheumatic-like symptoms in some people (amongst other things).
It and Aspartame (found in Sodas and artificial sugar [sweeteners]) are deadly slow poisons that should NOT be allowed anywhere near food never mind put in as an additive.
Do some research on the neuro toxic aspects of these additives, you will be shocked at what you find.
Dr. Batmanghelidj's books are available in most public libraries or can be purchased in good bookshops, they explain the reason why and how salt & water works the way it does and he explains in detail how dehydration is the underlying cause of a lot of our 'diseases'
Good Luck.
