Yes, you certainly may and it's very kind of you to care for others so much. I have cancer and well.. if God wants me to die I'll die but I don't believe in doing nothing to help the body get rid of it because it's certainly possible. Many have done it with various methods. To me simplicity has become a key (after wasting tons of money on supplements etc). I think God provides everything we need to stay healthy and cure ourselves, and it's right under our nose and it's dirt cheap.
