Abstract:

〔Abstract〕Objective: To perform pharmacognostic studies on Phlomis forrestii Diels. Methods: We identified the sources and
determined the shape properties with the help of microscopic and physiochemical ways. Results: Cangshancaosu is the dry complete
grass or the whole plant of Phlomis forrestii Diels. Its crude drug identification was described in details. Conclusion: The experimental
results can provide the theoretical basis for further development, utilization, and identification of Phlomis forrestii Diels.
