Homeopathy- As for the lactose, unless it is a bad reaction, I would probably not thing twice about one dose. Maybe some would feel differently, but that is just me.
With all those deficiencies you listed, I would consider that you are having issues with detox pathways. The link at the bottom of WuWei (Pat) siggy has a like to "heal thyself site" and all about WhoMe (Shannons) detox pathways site. Good stuff. It has helped me realize why we have issues and what I can actually do about it.
