Ginseng … Safety & Interactions

Ren Shen · Radix Ginseng

Contraindications

  • Acute excess heat or agitation without deficiency
  • Uncontrolled stimulant-type insomnia or marked upward-yang excess
  • Concurrent warfarin therapy without close monitoring

Cautions

  • MSK and broader clinical literature note interaction concerns with warfarin, glucose-lowering drugs, and stimulant-type responses such as insomnia or palpitations.
  • Different ginseng species and processed forms are not interchangeable, so Ren Shen should not be assumed equivalent to American ginseng, red ginseng, or leaf products.
  • High-dose or inappropriate use may cause agitation, insomnia, headache, or blood-pressure changes.
