Korean red ginseng (Panax ginseng)
What it is
Steam-treated Panax ginseng root, which converts ginsenosides (Rb1, Rg1) into rarer compounds (Rg3, Rh2) with distinct pharmacology from white ginseng. Meta-analyses support modest improvements in erectile function, fatigue, immune function, and glycaemic control. Evidence for cognition is mixed but positive in older adults. More stimulating than American ginseng — prefer American if anxiety-prone. Drug interactions are meaningful: avoid with warfarin, MAOIs, and certain diabetes medications.
Dose
200–400 mg standardised extract (4–7% ginsenosides) daily
Time of day & tips
Take in the morning (can be stimulating); cycle 8-12 weeks on / 2-4 weeks off; avoid with hypertension, autoimmune conditions, and stimulants
