Integrating textual criticism literatures with field survey, the name, classification and botanical originals of breeds of Tibetan medicine "Dida" were discussed in this paper. The results showed that it's very intricate and confusion in the names, breeds and botanical originals of "Dida", and those were the key restricting factors resulting in shortfall and difficult formulation in quality standard of "Dida". The similar situations are existing universally in ethnodrugs, and reflecting the necessity and urgency to collate ethnodrug breeds. On the other hand, Because of the morphologic description on the botanical origins of drug was often simple in the ancient literatures, and in most cases, the botanical origins of the drug were difficult to identify accurately on the basis of the literatures. So, in the collating the breeds, it's necessary to follow the principle of "according to the ancient literatures but no rigidly", and to pay attention to the historical vicissitude of the drug breeds and origins, and the survey of present resources and clinical using, draw actively on outcome of chemical and biological active researches. That inherited the characteristics and advantages of ethnodrugs, and promoted them them modernization.

OBJECTIVE：To invest igate the medication regulation of Tibetan medicine prescription of Punica granatum seeds， and to analyze the pharmaceutical property of it in the treatment of “Sanweihuo”（Me drod gusm) dysfunction induced-related diseases. METHODS ：Using Clinical Notes of Tibetan Medicine ，Medicine Standard of the Ministry of Public Health ：Tibetan Medicine as standard ，Tibetan medicine prescriptions of P. granatum seeds recorded in Sibu Yidian ，Yuewang Yaozhen and other medical records were collected ，and TCMISS V 2.5 software was used to analyze main indication and medicine frequency statistically. The core medicine combinations of the prescriptions were analyzed with Apriori algorithm （support degree ≥50％， confidence degree ≥90％)，and medication regulations were analyzed. Tibetan medicine “Ro Nus Zhu rJes ”vector model was used to analyze the properties of Tibetan medicine prescription of P. granatum seeds in the treatment of high frequency diseases ，and K-means cluster analysis was carried out for seventeen effectiveness. RESULTS ：A total of 300 Tibetan medicine prescriptions of P. granatum seeds were collected ，involving 104 kinds of main indications ，among which frequency of 18 kinds of indications was more than or equal to 10 times，including“non-indigestion syndrome ”（Ma Zhu ba) （76 times)，“wood cloth disease ”（Smug po) （46 times)，“edema”（Chu nad) （34 times)，etc. Totally 322 kinds of Tibetan medicines were involved. Among them ，21 flavors were more than or equal to 50 in frequency ，including Piper longum （192 times)，Amomum kravanh （164 times) and Carthamus tinctorius（134 times)，etc. Fifty-six core combinations were obtained ，mainly including P. granatum seeds-P. longum （192 times)， P. granatum seeds-A. kravanh （164 times) and P. granatum seeds-C. tinctorius （134 times). The prescriptions （13 pieces) with six flavors as pungent ，sweet and sour ，and with prominent medicinal properties such as roughness ，heat and dry effects could be used to treat “non-indigestion syndrome ”，and then included into type Ⅰ. The prescriptions （13 pieces) with six flavors as bitter ，sweet and pungent ，and with prominent medicinal properties such as cooling ，dull and heavy effects could be used to treat “wood cloth disease”，and then included into type Ⅱ. The prescriptions （11 pieces) with six flavors as sweet ，sour and pungent ，and with prominent medicinal properties such as dull ，heavy and moistening effects could be used to treat “edema”，and then included into type Ⅲ. CONCLUSIONS ：Tibetan medicine P. granatum seeds is often used in combination with the isothermal medicines such as P. longum ，A. kravanh . P. granatum seeds are also commonly found in cool prescriptions ，revealing that Tibetan medicine pays attention to “Sanweihuo”while treating diseases ，which embodies the academic thought of Tibetan medicine that “there is cooling in temperature ，and there is temperature in cooling ”.
