I clean my windows with vinegar and scrub my fridge with baking soda. Call me a tree-hugger, but I like reducing my reliance on harsher chemicals. So I think it's intriguing that vitamin C injections seem to be helpful in chemotherapy treatment for ovarian cancer.
More research is required to see if this effect is significant. But since nobody can patent vitamin C, there's apparently little incentive for big companies to fund such research. It would be sad if patients were denied a new treatment option just because there's no profit to be made.
