Golden Seal (Hydrastis canadensis) is an endangered herb and as a result is very expensive and often substituted by other herbs.
The substituted herbs usually contain the substance berberine which provides the yellow colour, but they do not contain hydrastine which is unique to Golden
Seal. Only HPLC enables this differentiation to be made. MediHerb® tests each batch of Golden Seal raw material and finished product to ensure the claimed levels of hydrastine and berberine are present. Using HPLC, MediHerb® is able to clearly differentiate true Golden Seal from other berberine containing herbs. The table demonstrates the difference between the various berberine containing species. The top trace is an example of substitution where a professional product being sold in Australia as Indian Golden Seal matched the trace of Coptis chinensis.

• to support healthy mucous tissue of the respiratory tract and reduce excess mucous
