Elymus repens

Limited

In an uncontrolled post-marketing study of 313 patients with irritable bladder, urethritis, cystitis or prostatitis, 32–53% were free of symptoms after 12 days of a fluid extract. The EMA judged this unsuitable for assessing efficacy because there was no control group.

Garden angelica

Angelica archangelica

Limited

Trials of the Icelandic leaf extract SagaPro: in 69 men with nocturia (Sigurdsson 2013) it did not reduce night-time voids overall versus placebo over 8 weeks, with benefit only in a subgroup; in a 6-week triple-blind pilot in 143 adults with overactive bladder (López-Seoane 2025, industry co-funded) it reduced daytime voids and the IPSS storage score versus placebo, with a non-significant trend for nocturia and no change in urgency.

Alpinia oxyphylla

Limited

Its main traditional indication is frequent urination, night-time urination and enuresis. Seed extracts reduced urine volume in mice, and the compound liangzhiin relaxed carbachol-contracted rat bladder strips; there are no clinical trials of the herb alone.

Wu yao

Lindera aggregata

Limited

Wu yao was often used for frequent urination in ancient times, but this use has not been systematically studied. It is the main herb of Suoquan Wan. In a randomised trial in children with bedwetting, desmopressin plus Suoquan gave more complete responses than behavioural treatment (37.5% vs 6.3%) and fewer relapses than desmopressin alone. Extracts improved bladder emptying in diabetic mice. The herb has not been tested alone in people.
