This prospective, noninterventional, multicenter 12-wk study in women with overactive bladder investigated the effectiveness of Granu Fink femina, a herbal combination of seed oil from Uromedic pumpkin (cultivar of Cucurbita pepo), Rhus aromatica (fragrant sumach) bark extract, and Humulus lupulus (hop) cone extract in a clinical setting. Patients documented overactive bladder symptoms and quality of life using questionnaires as well as diaries recording day- and nighttime micturition frequencies, urine leakages during physical activity or at sneezing or coughing, and use of incontinence pads. The full analysis set included 117 women (age: 21 – 78 y). Urination frequency decreased significantly with improvement during daytime in 49, 71, and 77 (out of 99) patients and at night in 45, 63, and 70 (out of 100) patients after 1, 6, and 12 wk, respectively. The mean frequency of leakages and used pads decreased significantly from 0.9 leakages and 2.0 pads at baseline to 0.4 leakages and 1.4 pads after 12 wk. In all measured aspects of overactive bladder-related quality of life, (coping, concern, sleep, social), statistically significant improvement was reached after 1 wk, with further improvement at 6 and 12 wk. Ninety-nine percent of the physicians and 95.4% of the patients rated tolerability as “very good” or “good”. Treatment with Granu Fink femina progressively improved overactive bladder symptoms and related quality of life with significant improvements already after 1 wk. Based on these effects and the observed excellent tolerability profile, Granu Fink femina may be considered a valuable therapeutic option for overactive bladder.


Figure 2. Concentration-dependent competition of DHT with [ 3 H]-DHT for binding to rat recombinant AR. An IC 50 value of 8.5 nM was determined for the binding of DHT. Data represents the bound radioactivity (cpm). 
Figure 3. Competitive binding of the test compounds at the AR. The test compounds pumpkin seed soft extract (, blue) and pumpkin seed oil (, red) and Δ7-sterols (, green) competed with [ 3 H]-DHT for binding to the rat AR within two independent measurements (a and b). Data in each graph represent the mean specific binding ± standard error of the mean (SEM) of duplicate measurements. Calculated IC 50-values from each experiment are indicated in Table 3. See Supplementary Tables S2-S4 for numeric data.

... In all four studies the manufacturer of the extract was involved. One observational study was investigating the effectiveness of a standardized herbal extract containing a combination of Cucurbita pepo L (Marrow), Rhus aromatica bark (Fragrant sumac), and hops, in women with overactive bladder (Gauruder-Burmester et al., 2019). Of the 113 patients included, nearly the half (61 patients) used concomitant medications (e.g., antihypertensive, levothyroxine, lipid/cholesterol lowering agents, low dose ASS, NSAIDS) within the frame of a routine clinical setting. ...

... %is enzyme catalyzes the conversion of testosterone to dihydrotestosterone, a potent androgen involved in the progression of prostate enlargement. ∆7-sterols, prominent in PSO, have been shown to inhibit both isoforms of 5α-reductase, particularly 5α-R2, which is highly expressed in the prostate gland (12,28). In vitro studies demonstrated that PSO and extracts could significantly reduce DHT levels, e$ectively reducing prostatic cell proliferation (28,29). ...
