Wobenzymes N are OK for many other ailments especially of the digestive tract. However they are not good enough to be used as a cancer therapy. They only contain 3% chemotrypsin. On the other hand Wobenzymes E contain 40% chemotrypsin and 40% trypsin.
It is the chemotrypsin that is the more essential ingridient to fight cancer and break down the protein envelope with which cancer cells protect themselves.
If you chew on a capsule/tablet and it burns your tongue, that means it contains substantial chymotrypsin.
I also like Wobe Mugos very much. both these are by the German company Mucos (www.mucos.de or www.mucos.cz/eng/Default.htm); US importer is Natural Vitamins. contains chymotrypsin 40 mg, trypsin 40 mg, 100 papinases (6x), calf thymus extract, & enzymes from peas, lentils, & papaya. Must be ordered directly from Germany.
Other brands that contain substantial chymotrypsin are Megazyme Forte/Omnizyme Forte (www.bluegrass.net/~jclark/omnizyme.htm; pH-sensitive enteric coated), Bio-Zyme (Chymotrypsin 15,000 USP, Trypsin 10,000 USP, porcine pancreas 100mg), and Nova Aurora (Professional Health Products Southwest; 817-467-8567; firstname.lastname@example.org; comes from New Zealand).
