Therapeutic placental fluid, including placenta cells and placenta factors. Placental cells and placental diffusion originate from placental tissue. Selective placental tissue can be amniotic membrane, corion, or striated corion. The placenta product of the present invention is useful for the treatment of tissue injury (such as wound or burn) of even patients, and can be applied to injury. Requirement 1: a method of manufacturing a therapeutic placenta product, characterized by its understanding of: obtaining a placenta tissue；To obtain placenta cells from the first placenta tissue； to obtain the second placenta tissue； to break the second placenta tissue and form placenta products, including the diffusion of placenta factors； to combine placenta cells and placenta dispersion. Second requirement: the method of the first requirement is characterized by the fact that the first placental tissue is a self marker of placental tissue. Requirement 4: the method of requirement 3, which is characterized by the process of acquiring placental cells including exposure of the first placental tissue to protection. Requirement 5: method of requirement 4,Its characteristic is that protein is a kind of adult. Item 8: method required in Item 7, which is characterized in that less than 10% of placenta cells can be released by contact. Item 9: any one of the required methods 1 to 8, which is characterized by the first placental tissue and the second placental tissue being amniotic fluid tissue. Requirement 10: Methods 1 to 8 of any one of the requirements are characterized by the fact that the first placenta tissue and the second placenta tissue are a kind of Koran tissue. Requirement No. 18: method of any of the above requirements,Placental products are characterized by one or more members selected from the group, including: outer matrix proteins； protein inhibitors； angiogenic factors； and placental factors, which promote epithelial cell transfer to the wound. Item 19: the method req
