Yuebawei refers to 8 kinds of genuine medicinal materials in south China area,namely Citri Grandis Exocarpium, Citrus reticulata, Amomum villosum, Pogostemon cablin, Morinda officinalis, Aquilaria sinensis, Citrus medica and Polygonum multiflorum. The results of this review show that, the pharmacological effects of Yuebawei are very extensive. It has significant effects in relieving cough and phlegm, anti-bacterial and anti-inflammatory, enhancing immunity, anti-oxidation, antidepressant, immune regulation and regulating gastrointestinal function. Its development and application prospects are broad, but most of the existing pharmacological studies stay on pharmacodynamic studies. In the aspect of the safety research of Yuebawei, there are few studies on the safety of other medicinal materials, except for the liver toxicity of P. multiflorum; at the same time, there are few comparative studies on the therapeutic advantages of Yuebawei and other local medicinal materials in clinical application. It is necessary to strengthen the research on the material basis of pharmacological action mechanism, and safety and efficacy observation of clinical medication for Yuebawei, so as to provide scientific basis for the development of new drugs and clinical promotion and application of Yuebawei.

Except for blank group,other groups were given 2,4-dinitrochlorobenzene to induce chronic dermatitis-eczema model. Since the third day of the experiment,two sides of right ears of the mice were given relevant medicine twice at 7:00 and 15:00,15 μL each time,for consecutive 12 d. In the tenth,thirteenth,sixteenth day of the experiment,the difference of thickness of right ears of the mice was calculated(the difference value before experiment),the times of scratching in ear of mice were recorded within 30 min. In sixteenth day of the experiment,ear swelling degree of mice was determined,and thymus index and spleen index in mice were calculated. Optical microscope was used to observe the pathological changes of ear tissues of mice. RESULTS:Compared with blank group,the difference of thickness of right ears,ear swelling degree,spleen index and scratching times were increased significantly in model group(P<0.05 or P<0.01). The epidermis of the ear tissue was thickened,the cell proliferation was obvious,and cavernous edema was found in the epidermis. Compared with model group,other indexes in were decreased significantly,except that the difference value of thickness of right ears in sixteenth day of the experiment,scratching times in ninth and fifteenth day of the experiment were decreased slightly in low-concentration group of water extract from Eriocarpous Glochidion and the thymus index and spleen index in medium-concentration, low-concentration groups of water extract from Eriocarpous Glochidion (P<0.05 or P<0.01). The pathological changes of ear tissue were improved in administration groups to certain extent. CONCLUSIONS:External administration of water extract of Eriocarpous Glochidion has good improvement effect against chronic dermatitis-eczema in mice, which is worthy of further development and investigation.
