I think I've seen this somewhere else. Honestly if it were me I'd stick with tried and true, peer reviewed, carefully assessed medical advice. That's just me but with the survival rate for oesophegeal cancer of around 6-7% and dropping lower after 5 yrs it's not something I'm inclined to mess with.
A bit different if you are an adult making decisions for yourself I think, than for a child with no choice in the matter.
Also natural doesn't mean safe or no side effects - everything has risks and side effects - even vitamins.
