How we grade severity & evidence

Severity levels

  • Contraindicated: These should generally not be used together.
  • Major: Potentially serious — often needs a change or close monitoring.
  • Moderate: Can be significant — usually manageable with monitoring.
  • Minor: Usually limited clinical impact.

Evidence grades

  • Established: Well documented — supported by controlled studies or strong clinical data.
  • Probable: Good supporting evidence, though not definitively proven.
  • Suspected: Some evidence suggests this interaction, but it is not well established.
  • Possible: Limited or conflicting evidence; the interaction may occur.
  • Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.

Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.

Of 23 documented Ginseng interactions, 16 are rated moderate — including this one.

What happens

Increased risk of diuretic resistance

Interaction Deep Dive

A case report suggests that the germanium content of a ginseng-germanium combination product led to hypertension and decreased furosemide effectiveness1. Theoretically, other loop diuretics may be similarly affected. It is thought that the germanium component was responsible for the adverse effect although it cannot be ruled out that ginseng may have been involved. Germanium has been noted to be nephrotoxic with increased concentrations of lipofuscin granules in the cells of the thick ascending limb of the loop of Henle 23.

Why it happens (mechanism)

Germanium may damage cells of the thick ascending limb of the loop of Henle, diminishing the cells' responsiveness to loop diuretics

Literature reports

1 report — tap to read

a) A 63 year-old man with membranous glomerulonephritis treated with furosemide and cyclosporine was hospitalized with unremitting hypertension and edema. Ten days prior to hospitalization the patient had commenced taking 10 to 12 tablets daily of Uncle Hsu's Korean ginseng, which contained germanium as well as ginseng. On admission, blood pressure was 186/100 mmHg and serum creatinine was 115 micromoles/liter (1.3 milligram/deciliter). The patient responded to 240 milligrams (mg) of furosemide administered intravenously (IV) every eight hours (during which time he was not taking the ginseng product). He was discharged home on furosemide orally 80 mg twice daily but elected to resume intake of the germanium-supplemented ginseng product. Within 14 days, the patient experienced worsening edema and hypertension necessitating an increase in his furosemide dose to 240 mg twice daily. On readmission to the hospital, the ginseng product was discontinued and the patient was given furosemide 240 mg IV every eight hours. Within 48 hours of discontinuation of the nutritional supplement, diuresis ensued and blood pressure control was established at 128/78 mmHg. The investigators observed a strong temporal relationship between discontinuation of the nutritional supplement and diuresis 1.
