Panax Ginseng (Korean / Asian)

AdaptogenEnergyCognitionLibido

The 'true' ginseng. Warming, stimulating, classical TCM use for vitality. Modest cognitive and erectile function benefits in trials.

EvidenceModerate

Moderate for cognition (especially in older adults), erectile function (Korean trials), cancer-related fatigue, and modest exercise improvement. Effects: 4–12 weeks.

Panax ginseng is the warming, stimulating Korean / Chinese variety (versus the cooling American ginseng). Its bioactive ginsenosides modulate the HPA axis, support nitric oxide production, and have mild stimulant effects via dopaminergic pathways. Multi-thousand-year history in TCM as a vitality tonic. Modern RCTs support modest improvements in cognition (working memory, reaction time), erectile function in mild ED, fatigue in cancer patients, and exercise tolerance. Not for chronic anxiety or insomnia phenotypes — can over-stimulate.

Form: Standardised extract to 4–7% ginsenosides. Red Korean ginseng (steamed, more warming) versus white ginseng (sun-dried, milder). Look for Cheong Kwan Jang or other reputable Korean brands.
Dose: 200–600 mg/day standardised extract.
Timing: AM. Not PM — stimulating.
Schedule: Cycle: 6–8 weeks on, 2 weeks off.
Side effects: Insomnia, irritability, anxiety, headache, palpitations, GI upset. Hypoglycemia in diabetics. Estrogenic effects in some.
Interactions: Warfarin — reduces efficacy (case reports). MAOIs — additive stimulant effects. Diabetes medications — additive glucose lowering. Caffeine, stimulants — additive overstimulation. Hormone-sensitive medications — estrogenic interaction.
Contraindications: Uncontrolled hypertension. Insomnia. Anxiety disorders (often makes worse). Hormone-sensitive cancers. Pregnancy / breastfeeding. Bipolar disorder.
Lab markers: BP, fasting glucose if diabetic. Cognitive batteries for objective tracking.
Food sources: Ginseng root in soups and teas (TCM traditional). Standardised extracts deliver more reliable dosing.
