Hi, I am mum to Adam who is only 18 and has suffered from CH for two years. Our local hosp diagnosed very quickly on first time needed to attend A & E. It breaks my heart to see him when the biggies hit as feel so useless. As I type I am in tears. He is not on any meds. I read your inputs on seeds, mushrooms and 02 but get really scared as I dont know how using these will affect him/ Even the 02 can damage lungs? How can I help my son but do the least harm to him?
