I’m afraid there isn’t anyone who truly knows this answer. There is a lot of information out there about the necessary dietary changes however. I urge them to do the research on their own. After all, healing is done by the self, and thus it helps for them to do the research themselves also.
Also keep in mind if we say “do this and that” and then it doesn’t work, we could possibly be held liable, which wouldn’t be good. No one here is a doctor. There are some who are working on degrees in chinese medicine or other eastern arts, but they aren’t certified either. Plus, the perspective of eastern medicine is different from western medicine.
Another point this brings up is – who is asking for the help? Have they asked for your help? If not, then you may be overstepping your bounds here. It’s ok to offer help, but if the person doesn’t want help there’s nothing you can do. If they do ask for help I would question why they aren’t doing the research themselves. Healing has to come from within. If they’re looking for someone to fix them, it’s not going to work either.
These are just some thoughts. That last paragraph I learned the hard way
