Superwoman - I've been helping people for a while who have serious candida issues. And whenever I read that that they gave up using borax I felt that it was a real shame. It is absolutely inevitable that you will suffer Herx reactions -- feeling awful -- whenever you take candida-killing nutrients like borax or iodine or turpentine etc. I feel really disappointed and sad when people give up a very successful protocol -- a protocol that is successfully killing fungus, bacteria, parasites etc in such large amounts. Isn't that what you want? And if you don't take borax then how are you going to defeat the fungus and cure yourself?
The trick is to reduce the dose of any successful protocol to personally bearable Herx levels. When the borax kills such large numbers of fungus the fungus breaks up in the body and releases poisons into the blood and these poisons will play hell with your liver and your hormones. So these Herx reactions are usually inevitable until you get the numbers down and then the Herx goes away. In fact any successful protocol that kills candida in large numbers will have Herx reactions. Indeed, if you took any other anti-candida protocol and felt great throughout -- with little or no Herx reactions -- I would probably tell you to dump the protocol because it isn't working to kill candida.
There are also minerals like magnesium chloride and sodium molybdate that will help to neutralize poisonous candida alcohols and aldehydes in your body. Magnesium is necessary to manufacture the alcohol dehydrogenase enzyme which converts alcohols to aldehydes. Molybdenum is necessary to help manufacture the aldehyde dehydrogenase enzyme which converts poisonous aldehydes to harmless citric acid in the body. So using these two minerals helps you to reduce the poisons in your body -- thereby reducing the Herx effects. You can read more about this here.
The main reason fruit is banned is because fruit contains sugar and citric acid has nothing to do with it. In fact I recommand alkalizing using lemons/limes(citrus fruits with no sugar) together with water and baking soda as part of the anti-candida protocol.
