The real danger with Lugol's is if you are allergic to it. In that case it can be fatal! Clark warns against many commercially prepared Lugol's as they have wood grain or some other type of alcohol in them. I ordered a bottle from her website, so the kind must be all right.
To kill salmonella bacteria the dosage is 6 drops in a 1/2 glass water 4 times a day. Hulda Clark says when they used to give Lugol'sIodine for people needing it for their thyroid they took 60 drops a day, so that makes the 24 drops a day not sound so bad.
However it would be imperative to first determine whether you are allergic to it. Kinesiology (muscle testing) perhaps?
