Think of an herbal monograph as a "botanical biography". Monographs include standard sections, such as Names (i.e. botanical nomenclature), Mechanism of Action, Therapeutics, Historical Uses, etc. and can be very helpful for preliminary fact-finding before running searches in the research databases, such as PubMed,and Embase. For example, knowing an herb's common and scientific names, and any chemical constituents that are unique to that species or genus will be useful in developing effective search queries.
AHP Monographs are available in the BU Library in print format only and are shelved in the Reference Section, call number RS141 .A65. AHP mission: "...to promote the responsible use of herbal medicines and ensure they are used with the highest possible degree of efficacy and safety." From their website.
