Thoughts on energy healing

What are your thoughts on energy healing and clairvoyance (healing someone through your energy). My husband was introduced(pressured) to it by his mother and now he's all in, paying a few hundred dollars per class and claiming he heals headaches and stuff. I'm so against it, it makes me nervous and it doesn't work. I have done research and a lot of what I have read says it's either fraud or heals temporarily. As far as clairvoyance, I think it's dealing with black magic and that freaks me out. My husband claims he sees spirits when "he gets his energy high enough" ahhhh idk what to make of this. I just know I want to protect my babies if this Is something evil.
