I found the two formulas in the Wynn& Marsden book. Looks like Jia Wei Er Miao San is mor for Stasis, and modified LDXGT is more when suppuration and Damp Heat predominate. As this is an older,Blood deficient dog (secondary to stasis), and the aspirate was mostly RBC with small rafts of tumor cells, I will go with Jia Wei Er Miao San and see how it goes. Thanks for listening. Jodi
