I read on a Gerson institute website that mixing the carrots and apple juice before pressing helps with the release of enzymes from the carrots. THis was Max Gersons opinion. The Green Star was mentioned on this web site, as being an excellant juicer for someone who does not have cancer. Since the Green Star is a modern juicer then this was an up to date opinion, and they were still reccomending the Champion with seperate press, as a cheaper method.
AS I mentioned before, why not have a chat with someone at the UK Gerson support group. These people are trained, and should know how important the carrot and apple juice thing is.They may have some cheap second hand ones!!!
David may be right that the Green Star is the best all round juicer........but is it the best one for your Mum? It could be sufficiant, but then she does have cancer
I can not advise you either way. In your position I would check with someone at the Uk group.Ask them about the Green Star.
