    • To prevent the product from being represented as a “traditional medicine”, any indicated traditional use claim must refer to the specific active ingredient(s) and recognized traditional system of medicine from which the claim originates when 1) both traditional and modern claims are present or 2) when claims originate from multiple systems of traditional medicine (e.g. Black cohosh is traditionally used in Herbal Medicine to help ease nervous tension).

    • When ALL of the active ingredients (MIs) in the product are used within the SAME identified system of traditional medicine AND the product makes ONLY traditional claims, listing of MIs in the traditional claim(s) is not required.

Preparation and quality requirements
  • The finished product specifications must be established in accordance with the requirements described in the source authority source’s product quality guidance.

  • The active ingredient must comply with the requirements outlined in the source ingredient database.

  • source authority is aware of peer-reviewed published cases where products labelled as containing Black Cohosh were found by laboratory analysis to contain different species. In order to prevent misidentification, the identification of authentic Black Cohosh must be completed by an unambiguous validated method such as the HPLC-ELSD, HPLC-MS or HPLC-MS/MS to determine the presence of a specific marker compound and/or the absence of others. For example, Actaea racemosa contains the triterpene glycoside cimiracemoside C (also called cimigenol-3-Oarabinoside), while most other Actaea/Cimicifuga species do not; conversely, other Actaea/Cimicifuga species contain the phenolic acid derivatives cimifugin and (or) cimifigin-3-O-glucoside (e.g. A. cimicifuga and A. yunnanensis, but not A. dahurica) while Black Cohosh does not. The commonly used markers, 23-epi-26deoxyactein and actein, are found in more than one species of Actaea and therefore their presence is not sufficient evidence alone of the unambiguous identification of Actaea racemosa [Source note 5]. The source authority recognizes that there are numerous methods which can be used to unambiguously identify Black Cohosh. These methods include, but are not limited to, those cited in the following references: Avula et al. 2007; He et al. 2006; Jiang et al. 2006; Brigham et al. 2004; Zerega et al. 2002; He et al. 2000.

Note: Data relating to the identification of Black Cohosh, using an unambiguous validated method, is not to be submitted with the reference-based product documentation, although it may be requested at the source authority's discretion.
