Christopher lists these diuretic herbs as helpful:
parsley and parsley root, juniper berry, gravel root (good for kidney stones, uva ursi, wild carrot (queen anne's lace), garden carrots (add this to your juices and some of the diuretic foods listed in number 28) ), cleavers, buchu, and burdock seeds (burdock is also a highly recommended blood cleanser)
some of these are part of dr schulze's kidney bladder tea and tincture.
Christopher says "diuretic herbs are used to
remove waste and poisonous materials from the blood/remove waste fluids form the tissues and cavities of the body, and maintain the action of the kidneys and stimulate normal excretory functions. This is especially valued when the kidneys are impaired (due to acute fevers, congestine, Bright's disease, etc) diuretic herbs lesson irritability of the genito-urinary tract, where the urine is excessively concentrated or acid; they dilute the urine, relieve the distress or uric acid concentrations by a solvent or flushing action, and eliminate uretic solids., Diuretic herbs alter the morbid conditions of the reanl excretions/they are antiseptic. Some diuretics increase the flow of urine by stimulating the cells in the kidneys to excrete more urine while others improve the blood circulation in the kidneys so that the fresh blood brings more fluids and wastes to be eliminated which forms the urine
Renal secretion is increased by raising the local pressure by dilating the afferent vessels or increasing the renal-blood supply and circulation through raising the general arterial pressure by increasing the action of the heart. This is performed by such herbs as black cohosh, candian hemp, lily of the valley, skill broom tops.
Other herbs work by stimulating the secreting cells or nerves of the kidney tissue.
These include such herbs as buchu, uva ursi, juniper berries (note if buying fresh herbs, juniper berries and cedar berries look alike except juniper berries have several or 3 or 4 seeds and cedar berries has only one seeds. A bulk herb company once sold me juniper berries when I ordered cedar berries..cedarberries help diabetics and are a big part of christopher's blood Sugar formula btw), corn silk, guaiac, fennel, cubeb, copaiba, pareita, atico, sandlewood. pippsissewa, etc.
When diuretics act upon renal solids (dissolving biliary concretions, calculi, stones or gravel) in the excretory passages, they are called lithotripic. They are antlithics when they prevent the fomentation of urinary and biliary concretions in the urinary passages.
the herbalist must know which diuretics influence the excretion of solid materials (sediment, gravel, etc) as these should be administered in combination with demulcent herbs such is marshmallow. couchgrass, slippery elm, etc which will sooth any irritation and forestall any stress that may arise during the elimination process. (in light of this, you might want to take some marshmallow root or demulcent herb with Dr shculze's formulas).
Christopher further recommends taking the diuretics during the day, on an empty stomach, avoiding physical exertion for the fastest diuretic action (but Schulze does recommend these 5 times a day so plan accordingly and do not forget the [physical exercise required in the incurables program). e says do not drive the kidneys in your haste to heal them as often renal troubles originate elsewhere" (source of this info is school of natural healing by Dr john Christopher page 266 and 267)
the herbs above are discussed at greater length in his book
also diuretic (herbs that increase the secretion and flow of urine, he lists but does not discuss about 300 other herbs..some of the ones that stood out to me or foods he mentioned are these:
