I do not know any reasons why you could not be on the Budwig Diet, but you might want to check with more knowledgeable folks in the Flaxseed support forum on that.  As I understand it, Budwig's flaxseed/cottage cheese  combo increases oxygen.  Just FYI, the combination of Budwig, Essiac Tea and Oleander extract have been reported to be successful here on multiple occasions.

Also, for that emphysema, I suggest nebulizing regularly with 5 parts colloidal (or ionic) silver to one part lobelia extract.  You can also add one part mullein extract if you can find it.  In addition, take a good look at a supplement by the name of ClearLungs Extra.  It is made up from a Chinese formula and has some wonderfuls herbs for healing and clearing the lungs.   I know of several people, including myself and my better half Luella May, who have used the nebulizing and the ClearLungs with great success.  In Luella's case, the combo cleared up severe asthma and pneumonia when all mainstream drugs and two hospital visits could do was knock them back a bit.

Another product which might be worth checking out is OxyGen, which contains the equivalent amount of oxygen per capsule as 12 drops of food grade H2O2.  I, Luella and my son all feel a noticeable boost in energy when we take the OxyGen.
