Phlebotonics for venous insufficiency
The Cochrane database of systematic reviews (2020) · Meta analysis · n=7690
Pooled data suggest that phlebotonics probably increase adverse events slightly, compared to placebo (RR 1.14, 95% CI 1.02 to 1.27; 37 studies; 5789 participants; moderate-certainty evidence).
Pine bark (Pinus spp.) extract for treating chronic disorders
The Cochrane database of systematic reviews (2020) · Meta analysis · n=1641
In a mixed group of participants with type 1 and type 2 DM we do not know whether pine bark extract decreases HbA1c (MD -0.20 %, 95% CI -1.83 to 1.43; one study; 67 participants; very low-certainty evidence).
Effect of pycnogenol supplementation on blood pressure: A systematic review and meta-analysis of clinical trials
Phytotherapy research : PTR (2020) · Meta analysis · n=922
Pooled analysis suggested that pycnogenol supplementation can reduced systolic blood pressure (SBP) of (-3.22 mmHg; 95% CI [-5.52, -0.92]) and diastolic blood pressure (DBP; -1.91 mmHg; 95% CI [-3.64, -0.18]).
Based on COSMOS trials (n=5765) showing equivalent of 2.0 years cognitive decline prevention. Effects most pronounced in those with cardiovascular disease. Study duration was 3 years. Effectiveness reflects conservative interpretation of memory and global cognition improvements.
Based on meta-analyses showing modest reductions in systolic (-3.22 mmHg) and diastolic (-1.91 mmHg) blood pressure. Evidence quality varies across studies and effect sizes are relatively small.
AI-estimated from published studies. Interpret as directional guidance.
Multivitamin has a higher evidence score (6/10 vs 6/10) and wins in 1 of 3 categories.
For reduce inflammation, Pycnogenol has a higher relevance score (80 vs 50).
