Phyllanthus niruri

A small annual herb that grows as a weed across the tropics; sources put its height anywhere between 15 and 70 cm depending on conditions. Rows of tiny 3.5 mm green capsules hang along the underside of each branchlet, resembling miniature amla, which is where the Ayurvedic name bhumi amalaki — the amla of the ground — comes from. AFTER uses a whole-plant extract.

The characteristic compounds are the lignans phyllanthin and hypophyllanthin, alongside flavonoids and tannins. In cell and animal work the extract interferes with calcium oxalate crystals — binding to their surfaces and slowing aggregation and growth — which is the mechanism behind the stone-breaker name, while separate animal work reports lower blood glucose and lower blood pressure. The missing piece is the bridge to people: very little of that has been demonstrated at ordinary oral doses in humans, the lignans show poor oral bioavailability in animal pharmacokinetics, and nothing in the proposed mechanism has any bearing on alcohol, sleep or the end of a long night.

Used for centuries in Ayurvedic and Amazonian practice as a bitter tonic. In AFTER it completes a traditional seven-botanical set; at 15 mg it is not doing anything a trial has measured.

Anyone who wants the traditional formula built the traditional way. Not for anyone taking lithium. Care if you take blood pressure medication, insulin, a sulfonylurea, or a medicine cleared by CYP3A4. Not in pregnancy or breastfeeding. Not for anyone hoping it will deal with a kidney stone — that is a medical matter and belongs with a doctor.

One strip on the tongue at the end of the night. It dissolves in under a minute, which is the entire argument for a strip over a capsule at that hour. Food is irrelevant at this amount. If you take lithium, skip it; if you take a CYP3A4-cleared medicine, the theoretical interaction is worth mentioning to your pharmacist, even though 15 mg makes it unlikely to matter.

Nothing you will notice. No sensation, no onset, nothing to measure the next morning. At two hundred times this dose over twelve months, the largest trial of the herb missed its primary endpoint, so zero is the honest expectation from 15 mg on a Saturday night.

Micali et al. (Journal of Urology, 2006;176(3):1020–1022) followed 150 patients after shock-wave lithotripsy; 78 took a P. niruri extract at 2 g a day for at least three months and 72 did not. At 180 days the stone-free rate was 93.5% versus 83.3% overall (p = 0.48), and 93.7% versus 70.8% in the 56 lower-calyceal cases (p = 0.01). There was no placebo and no blinding. Dhawan and Olweny (Canadian Journal of Urology, 2020;27(2):10162–10166) could pool only two clinical studies; those showed modest reductions in stone size (SMD −0.39, 95% CI −0.68 to −0.09, p = 0.01) and number (SMD −0.38, 95% CI −0.68 to −0.09, p = 0.01), and the authors concluded that limited clinical evidence supports modest efficacy pending further study. Nishiura et al. (Urological Research, 2004;32(5):362–366) randomised 69 calcium stone formers to 450 mg three times daily or placebo for three months and found no overall difference in urinary parameters; only a hypercalciuric subset showed reduced urinary calcium. Pucci et al. (International Braz J Urol, 2018;44(4):758–764) gave 56 stone formers 9 g a day as an infusion for 12 weeks with no control group; abdominal pain was reported by 37 of them (66%). Abu Hassan et al. (Heliyon, 2023;9(6):e16652) randomised 112 patients to 3,000 mg a day against 114 on placebo for 12 months in non-alcoholic fatty liver disease: there was no difference in the primary CAP measure (p = 0.869) or in liver enzymes, although the secondary fibrosis score improved (p = 0.001). Cochrane's review of Phyllanthus species against antiviral drugs in chronic hepatitis B (CD009004, 2013) covered five randomised trials and 290 patients, all judged at high risk of bias, and concluded there is insufficient evidence to support or refute their use. Not supported: any claim that this plant treats or prevents kidney stones, liver disease or hangovers — and none of the doses above bears any relation to 15 mg.
