In order to help a person on dialysis stimulate their kidney function, we recommend as a first step a course of Reishi mushroom in capsule form. Alongside this, taking an adaptogen such as Rhodiola is advised, as is spirulina, this super food that is very beneficial for the kidneys. In addition, the patient can consume gum arabic, since it was once used to treat kidney failure.
Special attention should also be paid to diet. Fruits and vegetables should be favored, such as watermelon, melon, citron, or kiwi. Meat should generally be avoided; the diet should be based mainly on vegetables, while being careful to regulate mineral levels such as calcium and potassium.
What the science says: kidneys and urinary tract
Here is what published research says about the remedies mentioned above, for information purposes — the studies address material causes, while healing belongs to Allah.
Kidneys and urinary tract
Cranberry reduces the risk of recurrent urinary tract infections in certain people, according to a Cochrane review (Explore, 2024); for kidney stones, abundant hydration and diet (citrate, less salt and animal protein) are the best-supported measures (Minerva Urol Nephrol, 2025) (Arch Ital Urol Androl, 2015). Orthosiphon, cherry stem, and birch have a draining effect. Precaution: a urinary infection with fever or lower back pain is pyelonephritis — antibiotics are essential; in case of kidney failure, do not take diuretic herbs or magnesium/potassium without medical advice.
