Any recommended Ionic Detox / Detox spots in the San Francisco/San jose area?

I'm looking for a good detox spot but unsure where to go. There used to be a woman who did detox privately where she set up shop. Had me releasing toxins through the soles of my feet but she has closed up shop.

Any recommendations in the san fran san jose area? Or maybe outside of this area. As I'm in need of another detox. Thanks in advance
