Benign prostate hyperplasia (BPH) is affecting numerous men, symptoms starting usually after the fourth decade. At an early stage of symptoms development related to BPH, pumpkin seed extracts are applied [1], [2]. Hence, the effects of a proprietary oil-free hydroethanolic pumpkin seed extract (EFLA® 940) prepared from seeds of the Styrian oil pumpkin, Cucurbita pepo L. ssp. pepo var. styriaca (Cucurbitaceae) and extraction with 60% ethanol/water (DERnative 15 – 25:1), were investigated in a single-arm, mono-center pilot study, on the symptoms of BPH [3]. In total, 60 men (95% confidence interval (CI): 60.3–64.3 years) took part in the pilot study. The extract was ingested as a tablet prepared with common excipients once a day. Assessment of changes in International Prostate Symptoms Score (IPSS) within the treatment period of 3 months was carried out, frequency of nocturia was recorded by bladder diary, postvoid residual urine volume was determined by ultrasound. As a major outcome of this pilot study, a significant symptom reduction of 30.1% at average was recognized for the total IPSS. According to IPSS questionnaire and bladder diary, nocturia significantly decreased over time (P < .0001) [Fig. 1]. After 12 weeks of treatment, postvoid residual urine volume was significantly reduced. After 8 and 12 weeks of intervention, the symptom alleviation also significantly (P < .001) improved QoL according to IPSS questionnaire.

The outcome of this pilot study indicates that the oil-free hydroethanolic pumpkin seed extract seems to provide significant health benefits in patients suffering from BPH related symptoms.
