We've been extremely well received and attended in the Quantum Light Center (E.E. System of Frankfurt) As I had no specific health issue and I didn't plan to have any E.E.S session, but my wife insisted in it, so we'd two 2h sessions and one night session. For sure there were other benefits but these were the immediate perceived: During the sessions: - I've cough out (expectorate), starting to cleaning my lungs. About two days after the sessions: - My hand dyshidrosis basically disappered. - Seborrheic dermatitis on the face also disappered - Bowel movements became more frequent and regular (with healthy poops) - Improved my sleep quality (it feels you've effectively rested).
