Good morning. I have a question for you re:Mast cell tumors. I have a case of a 16 year old Shih Tzu cross that one of my colleagues asked me to assess for herbal treatment. It has a MCT, diagnosed by fine needle biopsy, growing on the bottom of it's right front foot just behind and attached to the foot pad. It appears rather large to excise and achieve margins. So the owner would like to palliate only. I was thinking of using Xue Fu Zhu Yu Tang with Eh Zhu and San Leng. Is there anything topical you can suggest. In your last herbal course you spoke of DMSO. Would that be a consideration in this case?
