Black Cohosh

Herb

Actaea racemosa preparations marketed mainly for menopausal symptoms. Product-specific trials and combination products cannot establish the effect of black cohosh alone, while adverse-event reviews highlight uncertain causality and the importance of product identity.

Pharmacokinetic model

A route-level PK model for black cohosh is being prepared from published data. Dosing references, studies, and documented interactions are below; the app catalog is updated as models are validated.

  1. Assessing the combined effects of Black Cohosh, Soy Isoflavones, and SDG Lignans on menopausal symptoms: a randomized, double-blind, placebo-controlled clinical trial Pokushalov E, Ponomarenko A, Garcia C, Kasimova L, Pak I, Shrainer E, Romanova A, Kudlay D, Johnson M, Miller R · European Journal of Nutrition, 2025 DOI

    Randomized trial tested a combination of black cohosh, soy isoflavones, and lignans rather than black cohosh alone. Any reported symptom benefit therefore cannot isolate a black-cohosh effect or generalize across…

  2. Review of black cohosh-induced toxicity and adverse clinical effects Le Y, Li X, Guo X, Seo JE, Manjanatha MG, Mei N · Journal of Environmental Science and Health, Part C, 2025 DOI

    Review evaluated preclinical toxicity and adverse clinical reports, including liver-related concerns. Case reports and product heterogeneity limit causal inference, but the evidence supports caution and careful…
