As for low tech natural remedies, versus higher tech medicine, one of my favorite phrases (since childhood) is "an apple a day keeps the doctor away."
Still, I think technological medicine is needed at times. I'm not much for folk remedies; especially if they are also for sale.
As for a regular doctor, one of my regular doctors would often quote that phrase himself. He is an advocate of bicycling and healthy lifestyles, but he also uses technology when it's needed.
