Chinese herbs Yunnan Paiyao for preventing and treating hemorrhaging

Here is an article about Yunnan Paiyao a Chinese herbal concoction that is very effective as prevention and treatment for all kinds of bleeds.I still struggle with the fact why something this effective and non-intrusive  is not readily available in hospitals as an alternative to synthetic Pitocin that is routinely given as a preventative for hemorrhaging? I wish i had this knowledge when birthing my daughter. I did hemorrhage and firmly declined anything synthetic in my system. Luckily, my daughter breastfeeding stopped the bleeding but it would have been helpful if my midwife had Yunnan Paiyao in case i kept bleeding. Food for thought. Knowledge is power!! Here’s the link to the article.
