When google search, a post with Luella May led me to this forum. I have a 4 year old suffers from allergies and asthma and he had to take oral steroid 4 times so far this year. I plan to nebulize Colloidal Silver with mullium this fall when needed. Is Utopia the brand you guys recommend? I got Sovereign brand this week locally and want to get the right one. Also Leulla May mentioned Clearlung product, can it be given to a 4 year old and what's the dose? I appreciate any advice thank you. FYI he is high in dust mite allergy. Either this or cat or dog might have triggered his past episodes.
