Hi Cathy,
With fluid compartment disorders, I often think of Chai Hu Jia Long Gu Mu Li Tang, although the pulse isn't a great fit. You could try it instead of the XCHT.
When we want to both tonify Blood and pull off fluid, Dang Gui Shao Yao San is a consideration, in addition to what you're already doing.
Otherwise, given the overt Blood deficiency and history of chronic vomiting, I'd wonder about adding in Yi Guan Jian.
Finally, homeopathic Ferrum metallicum 30C can be helpful in animals vomiting their food undigested hours after eating.
Hope that helps,
Steve
