I started using this honey after I read some UCLA Health research that tested the potential to improve the effectiveness of breast cancer chemotherapy drugs in mice. While I am not a mouse, I am a cancer patient. I cleared it with my doctors, and started adding a tsp/day. I have experienced a marked improvement in my condition. While I cannot say for certain whether the addition of manuka honey contrubuted or whether it is a placebo effect, who cares if the results are positive.
