The present invention relates to a method for producing an oral placenta extract, and more particularly, to a method for producing an oral placenta extract, which not only improves symptom of menopausal symptoms but also improves liver function as well as improvement of liver function, And to a method for producing an oral placenta extract. The method for producing placenta extract of the present invention comprises the steps of pooling a plurality of placentas into one sample to detect AIDS and C-type infectious virus by a nucleic acid amplification device, and to detect the B-type infectious virus by an Iyai test A raw material inspecting step, a raw material inspecting step, and a raw placental inspecting step in the raw material inspecting step to remove amniotic membrane and umbilical cord and washing with water to remove blood； and after grinding the contents through the raw material disposing step, In a vacuum state for 15 to 25 hours； and a step of putting the dried villi tissues that have undergone the vacuum drying step into a reaction tank, adding purified water and hydrochloric acid, hydrolyzing the mixture at 100 to 120 ° C for 15 to 25 hours, A step of concentrating and evaporating hydrochloric acid to obtain a water-soluble substance； and a step of sterilizing the hydrolyzed liquid at 110 to 130 DEG C for 15 to 25 minutes A sterilization neutralization step in which activated carbon is added, filtered, neutralized with an ion exchange resin and sodium hydroxide to a pH of 6.8 to 7.2, and a total nitrogen is quantified in the hydrolyzed liquid, A liquid filtration step of filtering the liquid with the liquid amount adjusted by the filter, and a liquid filtration step of putting the liquid filtered in the liquid filtration step into a container And a sterilization step in which the extract of the liquid-filled container is sterilized by heating at 110 to 130 DEG C for 15 to 25 minutes.본 발명은 경구용 태반추출물의 제조방법에 관한 것으로, 더욱 상세하게는 갱년기 장애 증상을 개선할 뿐만 아니라, 원기회복은
