In preparation for this week's materia medica, I found a TCM reference for using the pair Ai ye with Asini Corri Colla (which I found out was gelatin) for several pregnancy-related issues such as bleeding during pregnancy and postpartum, and cold abdominal pain during pregnancy - disturbing the fetus. All of which I have seen in my midwifery practice. The prescription is written "separately warmed to melt"- apparently because if you decoct together it becomes a mess and reduces the absorption of the "ingredients". My question is if an appropriate cold lower burner (hope I am getting that right) presents, how much mugwort to how much gelatin and at what dose would be appropriate?

And now I am wondering if Artemesia vulgaris is the same herb. I always thought A. vulgaris was what was used in moxa, but now I am not so sure. If this is not the same herb, where do I acquire this herb? On the way into clinic I was thinking about this - are we talking mugwort jello? Maybe I could make mugwort gummy bears for postpartum hemorrhage - lol.

What you are talking about is Ass-hide glue/E Jiao. It is not gelatin from a packet. Unfortunately the price of E Jiao has skyrocketed due to the shortage in donkey hides. I cannot really speak of its use, I do not use any TCM animal products in my practice. It is commonly used with Mugwort for bleeding during pregnancy. Perhaps Andrew knows more about the amounts and other herbs it can be used with for this application.
