It was found in clinical observation of 84 cases of functional secondary amenia that the patient with endometrial thickness of less than 0. 5 cm manifested most as deficiency syndrome and the patient with endometrial thickness of more that 0. 5 cm manifested most as excess syndrome. Based on the therapeutic principle "illness of deficiency type should be treated by tonifying method and excess syndrome should be treated with the method of purgation and reduction"

a good therapeutic effect was attained. It is indicated that treatment of amenia based on differentiation of syndromes and the endometrial thickness have close correlativity.
