To establish a method for the identification and characterization of Herba Hyssopi and its adulterants, Nepeta bracteata and Hyssopus officinalis.
Applying stereo microscopy, optical microscopy, and their digital image techniques, the author conducted a comparative study on Herba Hyssopi its adulterants in terms of macroscopic and microscopic characteristics of the whole plant, small samples, and local features (stems, leaves, and flowers), well as the cross sections of stems and leaves and the microscopic characteristics of powders.
There were significant differences in stem, leaf, flower and odor among Hyssopus cuspidatus, Hyssopus officinalis and Nepeta bracteata. The microscopical characteristics of stem cross section were slightly different, but there were obvious differences in leaf cross section and medicinal powder of the three species.
In this study, the pharmacognostic identification characteristics of Herba Hyssopi and its adulterants, Nepeta bracteata and Hyssopus officinalis, were summarized, which can provide the identification basis for the supervision, standard revision and clinical use of Herba Hyssopi.
