Objective: We want to develop a Pre-evaluation method of traditional Chinese medicine(TCM) clinical prescription based on the improved algorithm

which can carry out the intelligent recognition and analysis of TCM clinical prescription. Method: Using mathematical methods

improved the method based on the calculation of Chinese medicine weighted

and the method is verified and analyzed by using two commonly used clinical prescription. Result: The results of classical TCM prescription of Suanzaoren Tang is sedative drugs found to account for 0.46 of the total party weights

so it can be inferred from the results for ‘the party is mainly composed of sedative drugs constitute’;analysis of the traditional Chinese medicine prescription Guilu Erxian Jiao is found that the number of Bhd drug ingredients for 1

accounted for the whole Party weight 0.56

Yin tonic medicine number 2

a total of 0.38 weights

so it can be inferred from the results for ‘the party is mainly composed of Yin tonic

with tonifying-Yang drug assisted’. Conclusion: This method can identify and analyze the accuracy of the clinical medical prescription of TCM.
