Another painful experience for many people is contact with poison ivy, poison oak, poison sumac, or some other poisonous plant. The irritant in poison ivy, poison oak, and poison sumac is urushiol oil. It takes only 1 nanogram (one billionth of a gram) to cause a rash. One quarter of an ounce of urushiol is all that is needed to cause a rash in every person on earth. Five hundred people could itch from the amount covering the head of a pin. Specimens of urushiol several centuries old have found to cause dermatitis in sensitive people. Poison ivy, oak, and sumac add up to the most common allergy in America, claiming half the population. Sensitivity to urushiol can develop at any time. A successful cure is anything that eliminates or destroys urushiol. Activated charcoal does effectively neutralize urushiol by adsorbing the poison.
Dr. Agatha Thrash writes in her book: a 38-year old sergeant was given a medical discharge from the Army because of an intense sensitivity to poison ivy. His sensitivity was so severe that one particular bout with the problem had resulted in a painful 5-week stay at Ft. Benning's Martin Army Hospital complete with IV fluids, cortisone and a struggle just getting back to normal.
His wife called us early
one morning asking us if we would see her husband. He had taken a walk
in the country the day before and now his hands, feet, face, and other
areas were swollen tight. His eyelids were swollen shut and his fingers
were so stiff he could not bend them. We were reluctant to treat him as
they insisted – without hospitalization and with simpler remedies than
cortisone (which gave him wildly distressing thoughts). When we saw him
he was feeling faint and nauseated. We showed his wife how to make charcoal compresses
and instructed her on how to mix charcoal for oral administration. With
these treatments he gradually improved during the day and could open
his eyes by the next morning and close his fingers enough to grasp a
steering wheel. After five days he was entirely well. We were all
impressed.” Rx Charcoal – Startling New Facts About The World’s Most Powerful Clinical Adsorbent page 81
