Hi there..
With regards to the honey it has antioxidant properties, however less than two percent of the honey's nutritional properties is comprised of vitamins and minerals, none of which are the vitamins the cancer center warns against taking as a supliment vitamin, c, e, and A - and selenium - this was from a pamphlet that my radiation department handed out. The honey is 80% sugar, 18 % water and two percent vitamins like, thiamine, niacin, etc.. No vitamin, a,c,e or selenium. Which are the anti oxidants they tell you not to take.
My dr. Approved it - and there is a cancer hospital doing a three year trial on use of the honey in Head and neck cancer patients and prevention of mouth sores. But I totally understand your dr.s concern. And your reluctance.do what he says. Best of luck to you and your mom... Hope she gets through this all and begins to feel better.
