I have been using Wobenzym N first for number of months and then added Trevinol ES.
Now I take them both for at least 6 months twice a day. I get them over Internet from US to Australia. I believe The systemic enzymes help to release accumulated/imbeded stuff from deep inside.
I eat often sauerkraut and is one of my favourite foods, mix yoghurt with yakult
and drink it every morning etc.
Forgot to mention that I used to get cold sores every few months for most of my adult life. Now I cant remember when was the last time I had it. Also have not been sick or had cold for a long time.
