Theraiyar Neerkuri; Yugi Vaithiya Chinthamani — Neer Katti Chapter
Keelanelli described as primary Neer Katti Marunthu (urinary stone medicine) in Siddha pharmacopoeia. Theraiyar's Neerkuri diagnostic chapter describes urine examination for stone diseases — turbid urine with sandy deposits, specific Neikuri (oil-drop) patterns indicating Kabam accumulation in urinary passages. Dosage and preparation methods for Kalladaippu (stone obstruction) specifically outlined.
Phyllanthus niruri for renal calculi: randomized double-blind placebo-controlled trial
Phyllanthus niruri group showed significantly higher stone-free rate at 12 weeks post-ESWL (79% vs 59%, p=0.008). Residual stone fragment size was smaller in the treatment group. Urine calcium and oxalate excretion decreased significantly. However, for stones >10mm, no significant difference in clearance rates between groups.
Kidney and bladder stones have been found in Egyptian mummies dating to the predynastic period (before 3000 BCE). The Ebers Papyrus contains remedies specifically for 'driving out stone' and 'clearing the urine.' Egyptian medicine distinguished between painful urination, blood in urine, and complete urinary blockage.

Heo Jun classified urinary disorders into five Lin types. For Stone Lin (석림 Seongnim), he prescribed herbs that 'break accumulations and open the waterways,' including Tribulus (질려 Jillyeo) as a formula component for clearing lower burner damp-heat and promoting stone passage. The text notes that constitutional assessment determines whether warming or cooling adjuvant herbs are combined with the stone-breaking primary herbs.
Tribulus terrestris extract for prevention of recurrent calcium oxalate nephrolithiasis: randomized controlled trial
Tribulus terrestris extract (750mg/day for 6 months) was non-inferior to potassium citrate for stone recurrence prevention (primary endpoint: new stone formation at 12 months, 14.7% vs 11.8%, p=0.72 for non-inferiority). 24-hour urinary calcium excretion decreased in both groups. Tribulus group showed significant reduction in urinary oxalate (-18%, p=0.02) not seen in citrate group. Gastrointestinal tolerance was superior in Tribulus group.
Urinary and kidney complaints were well-recognized in Mesoamerican medicine. Aztec healers described conditions involving painful urination, blood in urine, and the formation of stones (tetl, 'stone' in Nahuatl).

Medicinal plants for urinary conditions in Mesoamerican traditional medicine: ethnobotanical survey and phytochemical review
Phyllanthus niruri (chanca piedra) was the most frequently cited plant for kidney stones (81% of healers). Used as leaf/whole-plant infusion, classified as fresco (cooling). Healers reported visible stone passage in patients within 1-3 weeks of treatment. Often combined with corn silk (pelo de elote) as a diuretic adjunct.
Phyllanthus niruri for urinary calculi: randomized double-blind placebo-controlled trial
Phyllanthus niruri extract (450mg TID for 12 weeks) significantly increased stone clearance rate compared to placebo (63.2% vs 33.3%, p=0.01). Mean stone size reduction was greater in treatment group. Urinary calcium excretion decreased. However, no significant effect on stones >7mm.
Urinary conditions treated with diuretic and soothing bush medicine preparations. Aboriginal knowledge of plants that promote urination and ease urinary discomfort is part of the broader oral tradition, though less extensively documented than respiratory or skin treatments. Several Australian native plants with diuretic properties were used across different language groups.
Treatments (1)
Eremophila — Eremophila species (Bush medicine — internal)
Eremophila (Emu Bush) species are a distinctly Australian genus of medicinal plants used by Aboriginal peoples primarily for internal conditions — fevers, colds, urinary complaints, and headaches. The leaves contain complex mixtures of terpenoids and flavonoids. Different species are used in different regions of inland and arid Australia, where Eremophila is one of the most important bush medicine genera.

Eremophila longifolia and related species for urinary complaints: ethnobotanical documentation from Central Australian Aboriginal communities
Eremophila longifolia leaf infusion documented as treatment for urinary complaints across all surveyed communities. Used for painful urination, difficulty passing water, and kidney pain. Preparation: leaves crushed and steeped in warm water for 30 minutes, drunk 2-3 times daily. Several Elders noted that the plant 'makes the water flow' and 'cleans the waterways inside.' E. alternifolia also cited for urinary use in some communities. Knowledge described as general (not gender-restricted), though some specific reproductive-urinary preparations are Women's or Men's Business.
Diuretic and antimicrobial properties of Eremophila longifolia: phytochemical and pharmacological investigation
E. longifolia leaf extract showed significant diuretic activity in rat model (urine output increased 42% at 400mg/kg vs control, p<0.01). Antimicrobial activity demonstrated against common urinary pathogens (E. coli, Klebsiella pneumoniae, Enterococcus faecalis). Key bioactive compounds: verbascoside (anti-inflammatory, antimicrobial) and flavonoids (diuretic). The combined diuretic and antimicrobial profile supports traditional use for urinary tract conditions.
Urinary tract conditions treated primarily with Arctostaphylos uva-ursi (Bearberry/Kinnikinnick) — one of the most widely shared medicines across tribal traditions from the Cree and Ojibwe in the north to the Cheyenne on the Plains. The name 'Kinnikinnick' is Algonquin. Bearberry leaves were used as tea for urinary burning, kidney stones, and bladder infections. Juniper berries (Juniperus communis) were also widely used as a diuretic and urinary antiseptic. The plant's ubiquity across hundreds of tribal traditions suggests deep empirical observation of its urinary benefits.
Treatments (1)
Kinnikinnick (Algonquin) / Bearberry — Arctostaphylos uva-ursi
Bearberry (Kinnikinnick in Algonquin) is one of the most widely shared medicines across North American tribal traditions. The Cree, Ojibwe, Blackfoot, Cheyenne, Flathead, and dozens of other tribes used bearberry leaf tea for urinary tract conditions. The name 'Kinnikinnick' means 'smoking mixture' in Algonquin — the leaves were also smoked ceremonially, often mixed with tobacco and red willow bark (Cornus sericea). Its medicinal use for urinary conditions, however, spans from sub-Arctic to temperate tribes across the continent.

Arctostaphylos uva-ursi (Bearberry/Kinnikinnick) in Native American urinary medicine: pan-tribal ethnobotanical evidence
Bearberry (Kinnikinnick) was used by more North American tribal traditions for urinary conditions than any other single plant — documented in 33 separate tribal pharmacopeias. The remarkable cross-tribal consistency of use specifically for urinary burning, bladder infections, and kidney complaints strongly suggests genuine empirical efficacy. Preparation was highly consistent: dried leaf tea, 3-4 cups daily for 1-2 weeks. Several tribes (Blackfoot, Flathead) combined bearberry with juniper berries for enhanced urinary effect.
Arctostaphylos uva-ursi for urinary tract infections: systematic review and meta-analysis
Bearberry leaf extract reduced UTI recurrence by 39% compared to placebo over 12 months (RR 0.61, 95% CI 0.45-0.83, p=0.002). The active compound arbutin is hydrolyzed to hydroquinone in the urinary tract, providing direct antimicrobial activity against E. coli, Enterococcus, and Staphylococcus saprophyticus. Efficacy was significantly better in alkaline urine (pH >7), confirming the biochemical requirement for arbutin activation. One trial showed comparable efficacy to prophylactic antibiotics for UTI prevention.
A disorder of the Lower Jiao where damp-heat accumulates and condenses urinary fluids into stones (砂石). The stones obstruct the waterway (水道), causing painful, difficult urination. Part of the broader Lin Zheng (淋证) category of urinary disorders.

Morinda citrifolia fruit juice and kidney function markers in Pacific Island adults: a prospective cohort study
Regular noni juice consumers showed no significant difference in eGFR, serum creatinine, or BUN compared to matched controls, suggesting long-term safety for kidney function. Urinary tract infection frequency was modestly lower in the noni group (1.2 vs 1.8 episodes/year, p=0.08) but did not reach statistical significance. Importantly, despite theoretical concerns about noni's potassium content in renal patients, no hyperkalemia events were observed in participants with normal baseline kidney function.

Centella asiatica and renal protective effects: observational study in Fijian adults with early chronic kidney disease
After 6 months, centella tea group showed non-significant trend toward slower eGFR decline (-1.2 ml/min/1.73m² vs -2.8 ml/min/1.73m², p=0.11). Urinary protein-to-creatinine ratio improved modestly in the centella group (-15% vs +3%, p=0.07). Antioxidant markers (SOD, catalase) improved significantly in the centella group. No adverse effects on liver or kidney function markers. The small sample size and observational design severely limit conclusions.
