Chanca Piedra (Diệp hạ châu) whole-herb tea bags: This existing listing describes a 50 g (1.76 oz) retail pack of bagged herbal material sold under the name Phyllanthus niruri. The name “stone breaker” is a traditional nickname, not proof that this product treats or dissolves kidney stones. The actual batch's botanical identity, 50 g net weight, bag count, label instructions, and food-use quality have not been independently authenticated from a current physical-lot document.
Which Phyllanthus plant is listed?
The supplier describes Phyllanthus niruri whole herb rather than a concentrated extract, capsule or isolated compound. “Whole herb” identifies the marketed plant material, not an entire fresh plant enclosed inside each tea bag. The proportions of leaves, stems and other parts are not certified for this batch.
Royal Botanic Gardens, Kew recognizes Phyllanthus niruri as an accepted species. Kew also separately recognizes Phyllanthus amarus. Common names for related stone-breaker herbs can overlap, so a common name alone cannot certify the ingredient species. Ask for a current scientific-name label and supplier lot verification if the precise species matters.
How are the listed tea bags prepared?
Earlier seller information described 1–2 tea bags in 300 ml freshly boiled water, steeped for 10–15 minutes. These are catalog-based preparation details, not independent confirmation of the current package instructions, a medically tested serving, or a safe therapeutic dose. Verify and follow the directions on the actual package before using this product.
- Check the physical pack for botanical ingredients, food-use suitability and updated brewing directions.
- Measure the water specified on the package using a heat-safe container; mug size alone is not a reliable volume guide.
- Prepare using the verified package's bag count, water temperature and time; remove bags as directed, then allow the infusion to cool.
Buyer questions
Will this tea dissolve kidney stones?
No kidney-stone treatment, prevention or cure is promised. A systematic review of Phyllanthus niruri found only two eligible clinical studies and concluded that clinical evidence was limited. Research on a particular study preparation is not evidence this retail tea is equivalent or effective. Suspected kidney stones, urinary obstruction, fever or severe urinary pain require appropriate medical evaluation.
Is it a standardized extract?
No. The listed item is tea bags made for infusion; no extract ratio, standardized phytochemical concentration or batch-tested active ingredient content is documented. Do not convert milligram doses from capsules, tinctures or research extracts into numbers of tea bags.
Does the current pack taste bitter or contain caffeine?
The historical seller description calls the tea naturally bitter and without added flavors or caffeine, but no independent tasting, caffeine or additive report establishes those characteristics for the current lot. The illustrated drink color does not prove the taste or strength of the supplied material.
How many cups does a 50 g pack make?
The catalog lists 50 g total net tea weight, not 50 g in each bag. The number of bags and fill weight per bag have not been independently confirmed, so a reliable cups-per-pack estimate is not available.
Does “Diệp hạ châu” prove the species is P. niruri?
No. Common names are not an adequate substitute for scientific identification and supplier documentation. This listing uses the seller's botanical name, and physical-lot confirmation remains outstanding.
Safety and storage
The seller advises avoiding use during pregnancy, breastfeeding or while trying to conceive. Seek professional guidance before use if you take medications, especially those affecting blood glucose, blood pressure or clotting; have kidney or liver conditions; or plan surgery. Do not stop or alter prescribed medicines to use herbal tea. A botanical name is not a guarantee of clinical safety. See NCCIH guidance on herbal products and medicine interactions.
Store closed, cool and dry, away from heat, direct sunlight and moisture. Follow the actual package's best-before information. No independent shelf-life claim is made for the current batch.
