In tincture form, 3 ml, 3x/day
Children, pregnant or nursing women, and those with liver or kidney disease should avoid corn silk.
Horsetail (Equisetum ravense)
Reportedly first used for kidney troubles by the ancient Romans, horsetail is believed to have diuretic effects and soothe bladder and kidney irritation.
Up to 6 grams/day
Make sure you know which kind of horsetail to use; the species Equisetum palustre contains toxic alkaloids and should be avoided.
Juniper (Juniperus communis)
Juniper’s oils may increase urinary volume, which can help detoxify the urinary tract and break down stones.
1–2 grams, 3x/day
Excessive use may cause kidney irritation; monitor dosage closely.
Uva-ursi (Arctostaphylos uva-ursi)
Uva-ursi contains antibacterial agents that act as a urinary tract antiseptic, helping to remove stone-forming substances.
700–1,000 mg, 3x/day
Due to high tannin content, uva-ursi may lead to cramping, nausea, and vomiting; do not take for longer than seven to ten days.
Vitamin B6
Vitamin B6 is known to help lower urinary oxalate, a main ingredient in some kidney stones.
10–25 mg/day; 100 mg/day or more might be recommended under certain conditions.
Taken at levels higher than 200 mg/day, vitamin B6 may cause neurological side effects such as numbness in the extremities and difficulty walking.
