Phytochemistry, synthesis, analytical methods, pharmacological activity, and pharmacokinetics of loganin: A comprehensive review
Phytotherapy research : PTR (2022) · Systematic review
Loganin, an IG, is one of the main active ingredient of Cornus officinalis Sieb. et Zucc., which approved as a medicinal and edible plant in China.
The points come from one 8-week dose-comparison RCT of an aqueous root and leaf extract at 125, 250 or 500 mg a day against placebo in adults with self-reported high stress (PMID 38732539, 131 enrolled, 98 analysed). All three doses reduced perceived stress and were reported as safe, and the authors describe the effect as dose-dependent. The abstract gives no per-dose effect sizes, so the curve shows only that ordering, not how large each step is. It also does not show whether doses above 500 mg add more. Trials of other extracts (root-only extract at 600 mg a day, PMID 23439798, and a 240 mg extract, PMID 31517876) are not on this axis because milligrams of different extracts are not equivalent.
