Blast - I was going to say that, Nick

I think that the salient point here is that there are many enzymes in nature and an increasing number of synthetic ones. Without some, life as we know it (JIM) could not exist.
However the enzyme groups that sparked this discussion are primarily designed either by nature or by man to break down protein groups similar to those of which much of our body - especially our lungs - are constructed.
Hence enzymes that are applied to a greasy restaurant carpet, if allowed to become airborne either as aerosol droplets or residue dust may attack the human lung. The response of the bodies immune system may cause an attack of an auto-immune problem such as asthma.
Other enzymes, which do not act upon the relevant proteins will have no known effect.
To label all proteins as bad is as much a nonsense as labelling all bacteria as villains. Or all drugs, for that matter.
With products such as Prochem Enzyme Prespray (now withdrawn) I fully support Dougs position. With others, such as Auxillase, which has been tested in the same manner as a prescription drug, specifically to check for detrimental effects on the human body, that is a different matter entirely.
