The present invention relates generally to herbal materials and methods for making such materials in medicinally useful and pharmaceutically acceptable forms. Particularly, the present invention relates generally to Hydrastis canadensis (goldenseal) materials and methods for making such materials in medicinally useful and pharmaceutically acceptable forms. More particularly, the present invention relates a process which allows the standardization of the product to specified levels of bioactivity in both hydro-alcoholic tinctures and solid extracts in the processing of goldenseal materials to produce extracts which qualify as pharmaceutical grade compositions which are suitable for use in clinical or veterinary settings to treat and/or ameliorate diseases, disorders or conditions.
