Isatis root

Ingredient Profile

Modern Research Perspective

Isatis Root contains indole alkaloids, lignans, flavonoids, and polysaccharides. Cell and animal studies have explored antiviral, antimicrobial, inflammatory, and immune pathways, but preclinical findings do not establish broad clinical efficacy.

Human evidence is variable and preparation-dependent. Liver or kidney effects, allergy, interactions, dose, pregnancy, and long-term safety require careful assessment.

Traditional Function

In traditional Chinese medicine, Isatis Root is bitter and cold. It is used to clear heat and toxicity, cool the blood, and relieve sore throat or heat-related symptoms. Its use is interpreted according to heat and toxin patterns.
