Abstract

Prostate cancer is one of the significant causes of morbidity and mortality worldwide. Benign prostatic hyperplasia is another condition of the prostate which, like prostate cancer, is more common among ageing men and is linked to inflammation. In this study, a systematic review was undertaken to estimate the effect of turmeric or curcumin supplementation on prostate diseases. A comprehensive search was conducted in PubMed, Scopus, ISI Web of Science and Google Scholar up to 15 April 2020 to identify clinical trials assessing the effects of curcumin/turmeric alone or in combination with other herbs on prostate diseases. This led to the identification of 11 records comprising 745 patients who met the eligibility criteria. Eight studies were conducted on patients with prostate cancer, and three were on other diseases of the prostate. Although outcomes across the studies were heterogeneous, in some studies curcumin/turmeric supplementation had some favourable effects. This included beneficial effects on the levels of prostate-specific antigen (PSA) (2/6 studies), quality of life (1/2 studies), as well as on oxidative stress markers, feelings of incomplete bladder emptying, urination frequency, intermittency, urgency, weak stream, straining and nocturia. Curcumin/turmeric supplementation had no significant adverse effects among patients. This study demonstrated that turmeric or curcumin supplementation might have beneficial effects on some parameters related to prostate diseases, but it should be noted that some studies showed no effect. Therefore, further studies using curcumin-related compounds, particularly in highly bioavailable forms, are needed to assess the impact of curcumin on prostate conditions. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.
