I come from a very personal perspective regarding homeopathic and naturopathic medicine.
To make a long story short, I became very ill and the MDs couldn’t find the problem for many months. Out of desperation I went to a naturopathic school. Through diet changes, natural remedies and homeopathic treatment, I was diagnosed and have made great strides in my health, though I still have some chronic illness issues due to toxic chemical exposure.
That being said, there are also a lot of New Age influences in much of alternative medicine – especially with massage therapy and Reiki, crystals, etc. Stay away from these. But there is much science in homeopathy; in fact there’s a great book you might be able to find in your library called “The Science of Homeopathy.” It is widely used throughout Europe, where MDs and NDs work together.
The way I look at it, God gave us natural plants to use for helping our bodies to heal. Somewhere along the way, science began using artificial chemicals to “heal” everything, when in fact, they often just mask the problem. Think of ancient remedies of the Orient, Native Americans, etc. Even my grandma had many “home-made” remedies that really worked.
I also asked for direction from my spiritual director regarding some therapies I was not comfortable with and he led me to a priest who has much experience with the occult. This priest said that homeopathy is not against Church teaching.
Be cautious, do your homework, pray and ask Our Lord to lead you to the right people who can help you help your son.
