Would you want your doctor or friend to withhold possible life saving information from you?
Give them the information, and let them decide for themselves. I'm sure they both already know that main stream medicine does not work for most diseases.
You might want to let them know that all those crazy whacko holistic doctor/reseachers out there are CURING disease, not just controling symptoms, such as Dr. Kelly, Dr. Budwig, Dr. Clark, Dr. Day, Dr. Rath, Dr. Sinatra, Dr. Douglass, Dr. Shultz, Dr. Atkins, Dr. Moss, Dr. Saul, Dr. Mercola, etc. Maybe they should be paying less attention to the Physicians Desk Reference and learning more about health. It could save their lives.
