Its only true value is for adding to the water you spray your garden soil. Otherwise, it is only a caustic chemical when made the Lugol Medical Way.
You take 3 pounds of chemicals to make gallons of the stuff and then a few sell the stuff for a huge amount by the ounce. That would be fine, if the people doing the selling were doing so to help the garden soil, but even then, the Lugol solution is not real natural iodine, but only 2 very caustic chemicals mixed together with water. Lugol'sIodine was ALWAYS from DAY I a drug or controlled substance and carries the skull bones of death, because even small doses are very toxic.
