Numerous preclinical studies have shown that DSG has great potential in the treatment of various cardiovascular diseases in vivo and in vitro, especially in atherosclerosis.
Based on meta-analysis showing mean reductions of 5.39 mmHg systolic and 2.66 mmHg diastolic. Effects are modest and may not be clinically significant for all individuals. GI side effects increase notably above 6g.
Based on single RCT (n=23) showing no significant effect vs placebo. Traditional use claims not validated by clinical evidence. Effectiveness estimates are conservative given lack of positive RCT data. Well-tolerated in study population.
AI-estimated from published studies. Interpret as directional guidance.
