Majority of men are affected by symptomatic benign prostatic hyperplasia (BPH) from a certain age. Botanical extracts are frequently used in the early management of the symptoms. In a single-arm, mono-center pilot study, the effects of a proprietary oil-free hydroethanolic pumpkin seed extract on the symptoms of BPH were investigated. A total of 60 men (62.3 years [95% confidence interval (CI): 60.3–64.3 years]) with a total International Prostate Symptom Score (IPSS) of 14.8 (95% CI: 13.5–16.1) participated between January 2017 and October 2017 in the study by ingesting the oil-free hydroethanolic pumpkin seed extract once daily before going to bed during 3 months. Change in IPSS within treatment period was assessed. Frequency of nocturia was recorded by bladder diary, and postvoid residual urine volume was determined through ultrasound. Between baseline and after 12 weeks of supplementation, a significant symptom reduction of an average 30.1% (95% CI: 23.1–37.1) was seen for the total IPSS. Symptom alleviation had a high impact on quality of life (P < .0001) and was significant after 8 and 12 weeks of intervention (P < .001). Nocturia significantly decreased over time (P < .0001), as confirmed by IPSS questionnaire and bladder diary. Postvoid residual urine volume was significantly reduced at the end of intervention (baseline: 83.67 mL [95% CI: 58.02–109.3]; after 12 weeks: 63.11 mL [95% CI: 45.37–80.85]; P = .0394). These results indicate that the oil-free hydroethanolic pumpkin seed extract seems to be a very well tolerable, appropriate plant extract to support health benefits in a collective suffering from BPH related symptoms without the need of medical treatment.

Purslane extract (PE) is derived from Portulaca oleracea L., a medicinal plant used in traditional medicine for its antidiabetic properties. This randomized, placebo-controlled clinical trial was designed to evaluate the efficacy and safety of PE in improving glucose control, blood pressure, and lipid profile in adults with type 2 diabetes mellitus (T2DM) treated with a single oral hypoglycemic agent at baseline. Subjects were randomized to treatment with three capsules of PE/day or a matched placebo. Change from baseline to the week 12 end-of-follow-up visit measures of glucose homeostasis, hemodynamics, and lipid profile was compared by treatment assignment. In addition, these measures were evaluated in a subgroup of ‘‘responders,’’ defined as patients whose week 12 HbA1c was lower than baseline values, regardless of treatment assignment. This group was further assessed in subgroups of baseline oral hypoglycemic treatment. A total of 63 participants were treated with either PE (n = 31, 11 females, mean age 52.4 ± 7.9 years) or matched placebo (n = 32, 11 females, mean age 58.3 ± 10.8 years). In the total cohort, systolic blood pressure declined significantly more in the PE group than the placebo group: -7.5 ± 5.0 versus -0.01 ± 0.3 mmHg, P < .0001. In the responders’ subgroup, HbA1c declined significantly more in the PE group than the placebo group: -0.8% ± 0.4% versus -0.6% ± 0.5%, P = .03. Few adverse events were reported. These were mild and did not differ by treatment assignment. PE appears to be a safe, adjunct treatment for T2DM, significantly reducing systolic blood pressure in the total cohort and HbA1c in the subgroup of responders.

Echinacea purpurea has been widely used for the prevention and treatment of upper respiratory tract infections and the common cold. The restraint stress has been reported to suppress a broad spectrum of immune functions. The aim of this study was to investigate the protective effects of the pressed juice of E. purpurea (L.) Moench (EFLA®894; Echinacea) against restraint stress-induced immunosuppression in BALB/c mice. Echinacea significantly normalized the restraint stress-induced reduction in splenocyte proliferation and splenic natural killer (NK) cell activity (P < .05). Echinacea treatment significantly increased the percentages of CD4+ and CD8+ T lymphocytes in the blood (P < .05). In addition, Echinacea restored serum cytokine levels, including interleukin-6 (IL-6), interleukin-10 (IL-10), and interleukin-17 (IL-17), as well as the mRNA expressions of these cytokines in spleen (P < .05). Our findings suggest that Echinacea might have beneficial effects on restraint stress-induced immunosuppression by increasing splenocyte proliferation and NK cell activity, while modulating T lymphocyte subsets and cytokine levels in the blood.
