I will honestly be the naysayer and say that I don't think anything herbal is going to help in the slightest. I think you would be better off saving up all that money and putting it toward a round of chemo.
Doxorubicin (chemotherapy) can be used with some success as a rescue treatment to give you a bit more time, without doing a full chemo protocol. Even a single dose of doxorubicin can sometimes give you a remission for a couple of months.
ETA: Also I would ditch the garlic right away... garlic can be toxic and can cause a severe (fatal) hemolytic anemia.
