Hi Salad,
I'm not sure about chinese medicine, but i have been taking blackmores morning sickness tablets, not sure if there working, but am starting to feel better. i didnt have any ms with ds so it was a shock for me to get it this time! and like you said it so hard with a little one, but somehow you just have to get on with it for there sake, ds has actually been a good distraction!
just plenty of crackers, ginger beer and sleep when there sleeping, thats what ive been doing.

sorry i havent actually answered your question...i hope someone else can be of more help
