What are the herbal preparations of this plant?
This plant is Cimicifuga dahuricia, a species primarily used in traditional medicine to produce therapeutic preparations from its rhizomes. The most common medicinal form is a crude rhizome extract, which is often utilized to manage symptoms of menopause such as hot flashes and night sweats. These preparations are frequently formulated into concentrated tinctures or standardized powders to ensure consistent dosage of active compounds. Researchers study these extracts to understand their specific hormonal regulatory effects on the female reproductive system. Ongoing investigations into its chemical constituents aim to refine how these herbal preparations are used in modern clinical settings.
According to a study published by "Molecules (Basel, Switzerland)", the rhizome and fibrous roots of Cimicifuga dahurica were extracted with 70% ethanol to obtain crude rhizome extract (RC) and fibrous roots extract (FRC). UHPLC-Q-TOF-MS identified 39 compounds, mainly saponins and phenolic acids, within these parts of the plant. In L-02 cytotoxicity experiments, the IC50 of the fibrous roots was 1.26 mg/mL, which was slightly lower than the 1.417 mg/mL observed for the rhizomes. During a 90-day sub-chronic toxicity study, the FRC group showed significant increases in white blood cells, ALP, ALT, AST, BILI, and CHOL with a p < 0.05. These findings indicate that the fibrous roots of Cimicifuga dahurica are at risk of hepatotoxicity.
