Characterization of Corydalis (Papaveraceae s. l.) and Dioscorea (Dioscoreaceae) Species: 1. Root Anatomical Characters

Resin embedding methodology was evaluated for authentic herbal medicinal identification using tubers or rhizomes of Corydalis and Dioscorea in the current study. Dealing with hard herbal drug materials for anatomical works can be challenging, but using the resin embedding approach makes easier to dissect the herbal drugs. Corydalis and Dioscorea tubers are secondary organs considering the fact that they have main roots as well as the tubers or rhizomes. The tuber anatomical characters are not complicated; however, the characteristic anatomical features can be useful as identification tools for those well-known Oriental herbal medicines.
