What is it? / Overview
Panax ginseng is a studied adaptogenic herb, with evidence for modest, product-specific improvements in mental performance and physical fatigue outcomes, along with a distinct research base for erectile dysfunction and libido.
How is it used? / Administration
Form: Standardized root extract (Panax ginseng, Korean red ginseng preparation)
Typical dose studied: 200–400 mg/day
Timing: Morning, with food; avoid late-day dosing due to potential stimulating effect
Different from Siberian ginseng (Eleutherococcus, a different plant entirely) and American ginseng — 'ginseng' covers several distinct herbs with different research bases; look for Panax ginseng specifically. Hypertension/anxiety suppression here is a deliberate conservative-safety-policy choice consistent with how this app treats other stimulant-adjacent effects.
How well does it work? / Evidence
~ Moderate evidence
Who should avoid it?
Avoid with: Primary hypertension / High blood pressure; Atrial fibrillation / Atrial flutter; Generalized anxiety disorder
Interacts with: Blood thinners (Warfarin); Diabetes medications; MAOIs (Monoamine oxidase inhibitors); Stimulants
Already taking it? Evidence for optimal use patterns (continuous vs. cyclic dosing) is more tradition-based than rigorously studied.
