Because there are different viewpoints about prohibition of acupuncture at Hegu (LI 4) and Sanyinjiao(SP 6) during pregnancy

in the present paper

the authors make a preliminary analysis on the theoretical basis and time-window

and reasonable application of contraindicant acupoints from ① descriptions about acupuncture contraindication in Chinese ancient and modern medical books;② knowledge about the activities of the uterus during pregnancy in modern obstetrics and gynecology;(③ clinical) and experimental researches on the effect of acupuncture on the functional activities of the pregnant uterus;④ effects of acupuncture on the uterine contraction in different stages of pregnancy;and ⑤ possible mechanisms of the effect of acupuncture in different stages.In addition

the authors hold that ① contraindicant acupoints do exist

acupuncture of LI-4 and SP-6 may facilitate the contraction of uterus in all the pregnant stages

so there will be a possibility of miscarriage;② the sensitivity of the pregnant uterus to acupuncture stimulation may be increased along with the development of pregnancy

so

acupuncture therapy should be used cautiously in the early and middle stages

prohibited in the advanced stage and for gravida with weak constitution or habitual abortion.In this discourse

the writers also bring forward an initial idea that for stopping pregnancy

pregnancy-contraindicant acupoints maybe be applicable after changes of the functional state of pregnancy by applying drugs;and increasing the stimulation strength within the patient's tolerance is probably favorable to raising clinical therapeutic effect.
