I've not tried this myself - I'm going on what others have reported. It's a bit pricey, but it goes a long way. Something to try if nothing else works.
As for kidneys, try adzuki sludge. Even if your kidneys are fine, it's very nourishing:
Adzuki sludge for Potassium source highest in the world
This increases power and strength of Kidneys therefore it is also a good (1) diuretic and since kidneys regulate all salt and potassium in the body then this will make for great way to get rid of problems of (2)water weight gain or water retention or problems with (3) kidney failure or (4) salt retention or (5) potassium retention when kidneys not functioning up to par.
The technique used calls for boiling 1 cup of Adzuki beans in 1 quart (4 cups) of distilled water – you’re after removal of all nutrients of beans into the water! You can find Adzuki beans in a health food store, usually in bulk or order them online. When the water boils down then add another quart. When this boils down - discard the beans and keep the sludgy water, it’s good for maybe 4 + days, and drink (2-4 tbls) of the sludge 2x a day. Some people freeze the sludge in ice cube trays and used it as needed. In 2 months the kidneys should be considerably stronger. If too sludgy to drink once refrigerated, then just eat it, do not add salt in this case…just eat it plain… Pretty simple stuff…If kidney’s come to total working level in 2 weeks or so, then ‘up’ the dosage …
This is a great protocol to use to get someone off of dialysis machine from kidney failure within a couple months usually, if they respond well to it.
Remember: kidneys regulate salt and potassium in the body both… by making sure not too much of either in the body so you don’t die, however, potassium is the main food source also of kidneys… so how do you get kidneys to be better without it…so here’s a little note for those with kidney failure… so Drs. see the kidney’s as weak and in failure and take a person off of potassium so that the patient does not get potassium poisoning since kidneys not regulating potassium correctly (build up could kill you)… this is often a fallacy to take a person off of all potassium, (when all they needed was right KIND of potassium – the kind that feeds kidneys) so be careful, have Dr. monitor you to make sure this minor amount of adzuki sludge you are taking in does not cause problems, and that kidneys are handling the extra potassium kidney food without any build up of potassium in the body that kidneys can’t handle… thus with kidneys handling properly the potassium from adzuki sludge and being properly fed so that they are rejuvenating, usually in 2 weeks God willing, that then they are no longer failing or weak or at 50% or worse function, but instead making it back up to 100% functioning.
Why does this work??? If there is too much salt in the system and kidneys can’t process it all b/c kidneys are weak or whatever, then it does not matter if there is plenty of potassium as it is not the amount of salt that is to be regulated and it is not the amount of potassium that is to be regulated by kidneys – but rather the ratio of one to the other that is regulated! Get it? Therefore, when you have too much salt no problem, add potassium to balance it out… problem with most super high sources of potassium is that they have equally high amounts of sodium… whereas Adzuki beans are highest source of Potassium in comparison to amount of sodium in them which is nearly none (almost no sodium)….this is why this works….now you’re getting pure potassium and very little sodium… thus kidney’s are fed what they are looking for most… also for those with potassium deficiency… this is intense… but never underestimate the power of bananas with oranges for potassium… though you’ll have LITTLE luck with bananas alone, when you EAT (not juice) an orange, with the banana, now body feels immediate potassium relief! (or just by eating the orange alone.)
(For those with an interest, 3 other major and massive kidney specific foods are apples, asparagus and coconut oil – uh, though technically the coconut oil is for the adrenal glands that are ONE TOP OF the kidneys… kidneys do in fact LOVE it when you eat some coconut oil then go out walking…, NOT jogging, but walking is what kidneys are in love with, most esp. after having had coconut oil.)
So to reiterate this all, adzuki sludge 2x/day is great for you, but adzuki sludge 2x/day with eating one orange in the PM is better for you!
