1. Overview
Xī Yáng Shēn (西洋参), “Western ocean ginseng”, is the dried root of Panax quinquefolius, native to North America. It belongs to the category of Qi-tonifying herbs in the Chinese Materia Medica but is unique in being cool and Yin-nourishing rather than warm, which makes it ideal in Chinese herbal medicine for patients with Qi and Yin deficiency together with heat signs.
I prescribe Xī Yáng Shēn as part of bespoke herbal formulas from pharmaceutical-grade granules sourced from Sun Ten in Taiwan.

4. Modern research
American ginseng contains ginsenosides (Rb1, Re, Rd in particular), polysaccharides and polyacetylenes. Studies report adaptogenic, immunomodulatory, neuroprotective, hypoglycaemic and modest blood pressure-lowering effects. Several Western RCTs support Xī Yáng Shēn for upper respiratory infection prevention and for cancer-related fatigue (Mayo Clinic studies).
5. Cautions and contraindications
Avoid in patients with marked cold-deficient Spleen Yang patterns and watery diarrhoea. Traditionally considered antagonistic to Lí Lú. Caution with warfarin and oral hypoglycaemics — American ginseng can mildly lower blood glucose and may interact.
Important: Chinese herbs should always be prescribed by a fully qualified herbalist who is a member of the Register of Chinese Herbal Medicine (RCHM).
6. Treatment at my clinic
I prescribe Xī Yáng Shēn as part of tailored herbal formulas for chronic fatigue with heat features, perimenopausal exhaustion with night sweats, recovery from viral illness in patients who run warm and warm-natured constitutions requiring gentle Qi support. Every prescription is individually formulated following a full TCM assessment.
I see patients in person at my clinic in Wokingham, Berkshire. Online Chinese herbal medicine consultations are available.
