Hi Katia,
Thank you for your question. This is a fascinating topic! I agree with you; there is no good research showing human benefit for placentophagy. I am curious and, so, I did a very brief PubMed search. I see a pilot study that concludes placentophagy does not influence maternal postpartum prolactin levels or neonatal weight gain (Young et al., 2019). I see a second study by Benyshek et al. (2018) that surveys American women; 30% consume their placenta without adverse events. This study provides a pertinent rebuttal to the Centers for Disease Control and Prevention (CDC) case report. The CDC cites a case report of a late-onset neonatal group B streptococcal infection. It is good to see that there is research showing lack of harm to this ancient practice!
I like the recipe you give that steams the placenta with lemon and ginger. Aviva Romm gives a similar recipe in her book. Is that where you found it? Romm (2002) adds tienqi ginseng for those women who feel particularly weak after birth. With regard to processing: I would imagine, and this is just a guess since I am not well-versed on the topic, that tincturing may concentrate and preserve the remnants of pregnancy hormones left in the tissue. Cooking denatures proteins and may affect the steroidal structure of hormones rendering them less effective. Raw encapsulation may preserve micronutrients and the molecular structure of hormones but may raise the risk of bacterial contamination. The last statement is doubtful if processed properly but I want to put that out there. Additionally, some women may have a gastrointestinal tract that does not process raw proteins efficiently. In that case you could consider giving each dose of raw placenta product with a digestive enzyme.
With respect to traditional Chinese medicine, placenta is used historically. In fact, it is not only the mother that might use the placenta as medicine. It is prized as a tonic remedy that nourishes qi, blood, and jing. It is used for children who are not reaching sexual maturity at the appropriate age (late puberty), men for impotence and erectile dysfunction, and men and women for infertility. Chen and Chen (2004) provide a brief entry that says placenta, or zi he chi, replenishes jing, nourishes blood, improves lactation, nourishes qi and blood, and benefits lung qi (chronic respiratory disorders). Properties are sweet, salty, warm; channels entered include kidney, lung, liver; contraindication includes those who have yin deficient heat (Chen & Chen, 2004). The umbilical cord is used for wheezing and night sweats due to kidney yang and jing deficiency as per a classical text written in 741 C.E. (Chen & Chen, 2004). Many modern TCM practitioners will not use human placenta but might substitute cow or pig placenta.
As far as use in China, I am not aware practitioners using raw placenta. The use of raw food, in general, is discouraged in Chinese culture and medicine. Additionally, Chinese medicine does not use tincturing extensively but will use alcohol, mostly rice or sweet potato hard alcohol, infused with herbs. In my training, I was taught that the postpartum use of placenta is cooked into a soup with other qi and blood nourishing foods and herbs. The new mother would eat this for several days and the family might share it. Ingredients in this soup usually include things like rice, root vegetables, black chicken, jujube dates/da zao, fresh ginger/sheng jiang, Chinese yam/shan yao, astragalus/huang qi, dong quai/dang gui, red ginseng/hong ren shen, processed rehmannia/shu di huang, cordyceps/dong chong xia cao and other tonics. The herbs selected are usually based upon the clinical presentation of the woman consuming them. There is no generic recipe and the focus is on strengthening the deficiency of fluids, blood, qi, and jing that childbirth can often cause.
So, in summary, if I were a woman, I would probably eat my placenta. I would not, however, eat a dead baby. 😊
All my best,
Andrew
