American ginseng

Panax quinquefolius

Chinese medicine regards it as more 'cooling' than Asian ginseng and uses it for fatigue and thirst. Some studies find a slight effect on post-meal blood sugar and colds; evidence is limited.

Safety notes

May interact with warfarin and diabetes medicines. The wild plant has become rare from overharvesting and is listed in CITES Appendix II.

Cautions by tradition (3)
  • Chinese materia medica: Caution with a cold, damp stomach.
  • Haudenosaunee (Iroquois) medicine: Choose cultivated; interacts with blood thinners and diabetes medication.
  • Cherokee (Tsalagi) medicine: Not in pregnancy or with high blood pressure; wild ginseng is endangered, buy cultivated.

Preparation

The dried root as tea, slices or extract. No dosage is given here.

Use in traditions

Indigenous peoples used the root medicinally. In the 18th century a Jesuit found the plant in Canada, starting a large export trade to China that continues today. Ody describes how Chinese physicians adopted it into their own system.

Attributed effects

Xi yang shen strengthens the qi, nourishes yin and body fluids and calms: in chronic cough, wasting diseases, mild afternoon fever and night sweats from yin deficiency, and fatigue in exhausting conditions.

Preparation and amount

Traditional dosage: 3–9 g a day, usually in a decoction. Unlike Chinese ginseng, which stimulates qi and yang, American ginseng nourishes blood and yin and slows the pace; this makes it more suitable for daily use. Rare from overharvesting: choose organic, forest-grown roots.

Caution: Caution with a cold, damp stomach.
