Crude drug 'SanJagYag' has been used mainly as a pleurisy, abdominal pain, female disease and gastropathy. To clarify the botanical origin of SanJagYag from Korea, the anatomical characteristics of Paeonia japonica, Paeonia lactiflora and Paeonia obovata of Paeoniaceae were studied. As a result, it was clarified that SanJagYag was the root of Paeonia obovata.
