To evaluate whether an aqueous seed extract of Terminalia chebula Retzius inhibited development of atopy in vivo, we used a 2,4-dinitrofluorobenzene (DNFB)-induced animal model of atopic symptoms to investigate the effects of the extract. We measured CD4+ cell numbers by hematoxylin and eosin (H&E) staining, and determined the expression levels of matrix metalloproteinase (MMP)-9, interleukin (IL)-31, and T-bet genes, in this animal model.

Daphne genkwa (Thymelaeaceae) has been used as a folk medicine in China. We investigated the effects of D. genkwa and Jyu-So-To on various pharmacologic models in mice including the azoxymethane (AOM)-induced colonic aberrant crypt focus formation assay, ornithine decarboxylase (ODC) activity assay, and two types of mouse ear swelling model. Administration of 236.3 ppm of Jyu-So-To in drinking water significantly suppressed AOM-induced colonic aberrant crypt focus formation (p < 0.05), with an inhibitory ratio of 46.7%. The effects of several extracts with organic solvents of D.
