Maybe only time will tell.
Time has told. Go back 100 years and see where we were with the kind of herbs and spices recommended.
Go back 70 years before antibiotics.
Go back 30 years to a time when my daughter would have died young.
Time has shown what works.
Time and experience has also shown us who you can not trust. The snake oil salesmen have not changed their pitch in a century. They just use the internet now.
There is only one way to tell which are snake oil salesmen and which are not. That way is to skeptically and rigorously examine the claims. By best-friends-brothers-cousin says so is not rigorous examination.
