>>50mg of a solution is different from 50mg of iodine. Way different.
He was referring to 50 mg of Lugols solution - 5% iodine, 10% potassium iodide,85% distilled water - yielding 6.25 mg per horizontal drop -- and/or Iodoral, which contains 20mg iodine, 30mg potassium iodide (the 50 mg per tablet) in a colloidal silica base.
Then he needs to specify that. Saying 50mg of iodine is not saying a diluted solution and is a toxic level. If you read the whole thread the debate started with the content of iodine in black walnut hull, which is significant. But he said that 15mg of actual iodine was not significant and that is when he said 50mg. Saying 15mg is not significant then recommending 50mg iodine implies 50mg of actual iodine, not 50mg of a diluted solution. Especially considering the fact that liquids are not measured by millgrams (mg), but rather in milliliters (ml). Therefore his claim again implies an amount of elemental iodine, not the diluted liquid solution.
