What Is Riñosan? The Peruvian Kidney Blend Explained
The Peruvian kidney blend explained
If you spend any time around Peruvian wellness traditions, "Riñosan" comes up a lot. It's not a single herb — it's a blend, named for the Spanish words riñón (kidney) and san (healthy). The combination has been used for generations in the Andes for kidney and urinary support. Here's what's in it, what it does, and how to take it.
What's in the blend
Traditional Riñosan combines four of Peru's most respected kidney-support herbs:
- Chanca Piedra (Stone Breaker) — for kidney stone support and overall kidney function
- Cat's Claw (Uña de Gato) — for inflammation and immune support
- Horsetail (Cola de Caballo) — silica-rich, traditionally for urinary flow
- Huamanpinta — a less-known Andean herb used for kidney inflammation
The idea isn't that any one herb does everything. It's that they cover different angles of kidney wellness, and together they give a more complete daily support routine than any single herb alone.
What it's traditionally used for
- Daily kidney function support
- Urinary tract wellness
- Helping pass small kidney stones
- Reducing kidney-area inflammation
- General hydration and fluid balance
Peruvians often drink it as a daily afternoon or evening tea, especially during periods when they want extra kidney support — long days of physical work, heavy meals, or after holiday eating.
*These statements have not been evaluated by the FDA. Riñosan is not intended to diagnose, treat, cure, or prevent any disease.
Why a blend instead of single herbs?
You could absolutely take Chanca Piedra alone, then Cat's Claw alone, then horsetail alone. People do. The reason blends like Riñosan exist is convenience and balance. One cup, four herbs, complete support. You don't need to brew three teas a day or take six different capsules.
It's also gentler than mega-doses of single herbs. Each component is at a moderate level, which means you can take it daily for longer without your body adjusting.
Tea or capsules?
Riñosan Tea
The traditional format. Riñosan Blend Tea comes as 25 tea bags. One cup daily, ideally after meals or in the afternoon. Mild, slightly earthy flavor.

Pairings
Riñosan is a complete kidney support blend on its own, but some customers stack it with:
- Standalone Chanca Piedra capsules — for extra kidney stone support
- Horsetail tea — for additional urinary support
- Dandelion Root tea — for kidney/liver dual support
Side effects and cautions
Generally well tolerated. Talk to your doctor before starting if you:
- Take diabetes, blood pressure, or blood thinning medications
- Have an existing kidney condition
- Are pregnant or breastfeeding
- Are scheduled for surgery
FAQ
How long until I notice anything?
2–4 weeks of consistent daily use. Like most Peruvian herbal traditions, gradual support not instant fix.
Can I take it long-term?
Yes. Many traditional users drink it daily for years. For continuous use, occasional 1-week breaks every couple of months are reasonable.
What does Huamanpinta do?
It's a lesser-known Andean herb (Chuquiraga spinosa) traditionally used for kidney inflammation. Less studied than the other ingredients but a long history of folk use in the Andes for urinary comfort.
