It has been my experience that the internet itself can be a better doctor than a real life one. For many years I had a bad back, saw doctor's, and they did nothing. Then I found out what was wrong on the internet by sheer accident. Same with my neck, and a heap of other things.

Doctors are reluctant to suggest herbal supplements or unusual approaches. Even if there is a lot of anecdotal evidence for efficacy they may not be accepted in mainstream medicine. In such cases doctors don't want to risk their careers giving advice to take them or risk potentially giving false hope to the patient.

I'm not saying, by the way, that you should necessarily turn to herbal alternatives by the way. Just that there is a wealth of information on the internet and no doctor can know all of it. Not do they have time to research each and every patient to discover whether there have been new studies. I'll give an example:

There have been a lot of studies proving that fasting can have a massive positive effect on survival rates for cancer patients undergoing chemotherapy, but no doctor will suggest you should fast before chemo because it's not customary practice. It's still on the fringes of medical knowledge.

If you describe what's wrong with your Aunt maybe someone can point you in a helpful direction.
