Stone Breaker
Phyllanthus Niruri

Medicinal Facts
Phyllanthus niruri, commonly known as Stone Breaker, is renowned for its diverse array of bioactive compounds, including phyllanthin and hypophyllanthin, which are central to its pharmacological effects. This plant sits at the intersection of traditional Ayurvedic and Amazonian medicine, where it is used for liver health and kidney stones, and modern pharmacological research, which explores its antiviral and hepatoprotective properties. Its multifaceted actions are attributed to its ability to modulate oxidative stress, inflammation, and viral replication. The plant's traditional use as a remedy for kidney stones is supported by its diuretic and anti-lithic properties, which have been validated in contemporary studies.
What it helps with
Kidney stones & urolithiasis
Phyllanthus niruri contains compounds like phyllanthin that inhibit calcium oxalate crystal formation and aggregation, a primary component of kidney stones. It increases urinary excretion of magnesium and potassium, which are natural inhibitors of stone formation. Animal studies and traditional use support its role in reducing stone size and facilitating their passage.
Liver protection & detoxification
Phyllanthin and hypophyllanthin in Phyllanthus niruri enhance the activity of hepatic antioxidant enzymes such as glutathione S-transferase and superoxide dismutase. This action protects hepatocytes from oxidative damage and supports liver detoxification processes. Human trials have shown its efficacy in improving liver function markers in hepatitis B patients.
Antiviral activity
The plant's lignans, including niranthin, inhibit viral DNA polymerase and reverse transcriptase, which are critical for viral replication. This mechanism has been demonstrated in vitro against hepatitis B and other viruses, suggesting potential as a supportive antiviral agent.
Anti-inflammatory effects
Phyllanthus niruri modulates inflammatory pathways by inhibiting the NF-kB signaling cascade, reducing the expression of pro-inflammatory cytokines like TNF-a and IL-6. This action is supported by animal studies and traditional use in inflammatory conditions.
Antioxidant support
The plant's polyphenolic compounds, such as quercetin and rutin, scavenge free radicals and enhance endogenous antioxidant defenses via the Nrf2 pathway. This contributes to its protective effects against oxidative stress-related damage, as shown in preclinical studies.
Digestive health
Traditionally used for digestive issues, Phyllanthus niruri's bitter principles stimulate bile flow and improve digestive efficiency. Its role in reducing gastric ulceration is attributed to its ability to enhance mucosal defense mechanisms and reduce gastric acid secretion, as evidenced in animal models.
Blood sugar regulation
Phyllanthus niruri may support glucose metabolism by enhancing insulin sensitivity and modulating glucose transporters. Animal studies suggest its potential in reducing fasting blood glucose levels and improving lipid profiles, though human data are limited.
Key active compounds
Phyllanthin
A lignan with hepatoprotective properties. It enhances hepatic antioxidant enzymes and inhibits viral DNA polymerase, contributing to liver health and antiviral effects.
Hypophyllanthin
Similar to phyllanthin, this lignan supports liver detoxification and exhibits anti-inflammatory properties by modulating NF-kB signaling.
Niranthin
A lignan known for its antiviral activity, particularly against hepatitis B, by inhibiting viral replication enzymes.
Quercetin
A flavonoid that acts as a potent antioxidant, enhancing Nrf2 pathway activation and reducing oxidative stress.
Rutin
A glycoside of quercetin, contributing to the plant's antioxidant capacity and supporting vascular health by strengthening capillaries.
Geraniin
An ellagitannin with strong antioxidant and anti-inflammatory effects, contributing to the plant's overall therapeutic profile.
Ellagic acid
A polyphenol with antioxidant properties that supports cellular protection against oxidative damage and modulates inflammatory pathways.
What the research says
Research on Phyllanthus niruri is robust in the areas of hepatoprotection and antiviral activity. Human trials, particularly in hepatitis B patients, have demonstrated improvements in liver function markers, attributed to phyllanthin and hypophyllanthin. Antiviral studies highlight the lignans' ability to inhibit viral replication, though most evidence remains preclinical. The plant's traditional use for kidney stones is supported by animal studies showing reduced stone formation and enhanced urinary excretion of inhibitors like magnesium. The primary limitation is the variability in bioactive compound concentrations across different preparations, which is addressed by standardizing extracts to specific lignan content.
Typical dosage
For tea or infusion, steep 1-2 teaspoons of dried Phyllanthus Niruri leaves in 8 ounces of boiling water for 10-15 minutes, and consume up to three times daily. For tinctures, a common dosage is 20-30 drops in water or juice, taken up to three times a day. Capsules and powders typically recommend 500 mg to 1,000 mg per day, divided into two doses. Always start with the lower end of the dosage range and adjust as needed, consulting with a healthcare provider for personalized advice.

Interactions & Warnings
Use with caution
Phyllanthus Niruri should be used with caution by individuals with low blood pressure or those on blood pressure medications, as it may enhance hypotensive effects. Pregnant or breastfeeding women should consult a healthcare provider before use. High doses may lead to gastrointestinal discomfort.
Herb Interactions
Both herbs may lower blood pressure, potentially leading to hypotension if used together.
Combined use may enhance antimicrobial effects, but caution is advised due to potential blood pressure interactions.
