Replied By Badabing! (Cape Town, South Africa) on 05/11/2013Hey Chris, Regarding dosages. Borax is pretty safe at low dosages. Its toxicity is lower than table salt. You'd have to be taking a lot before things would dtart to go wrong for you health-wise. As a guide: if you dissolve a level teaspoon (5ml) of borax in a litre of water and then consume 5ml of that per day then you are taking in somewhere in the region of 7mg of borax per day. That's okay for a maintenance dose. Your 1/4 teaspoon is low but perfectly fine too.
My best advice is to start low and then really learn to listen to your body. Listen to how it feels. Pick up the dosage a little and then see. Trust yourself and your body. You'll do fine.
Good health to you!
