I’d researched this and found some evidence that Manuka Honey can be helpful to delay the onset of G2 mucositis. It needs to be high MGO, which is expensive. I did buy some from the New Zealand Honey Co.

I ended up discontinuing it because -
- I got G2/G3 mucositis anyway
- I found Healios rinse to be more helpful
- I thought Healios and Salt & soda rinses should form the base of my rinsing routine, and adding honey on top of those was too much
- I couldn’t stand the taste after a while

My radiation oncologist did say there could be some weak evidence of benefits and was fine with me playing with it.
