Why is it dangerous?
Magical thinking, when it comes to health care, can lead to tragedy. Just take Penelope Dingle, for example. She was seeing homeopath Francine Scrayen for her cancer. If Penelope had gone to a medical doctor (note, they have an MD behind their name, not ND, DC, or DH), she might be alive today. Now all we have is her diary, the coroners report (PDF), the documentary, and the cease and desist letter from the homeopath trying to cover things up…silly homeopathy, haven't you heard of the Streisand Effect?
