Livingstone in Africa
Dr. Livingstone lay dying along side a trail in Africa and each day he was getting weaker and weaker. After several weeks all his body fluids were coming out of him .. he gave himself two more days to live.
Then, a very old black man stopped on the trail .. came back and cocked his head and looked him over very carefully. He pulled some of the grass growing under his cot and put it in a pot of water by their fire and boiled it and let it cook and gave him a cup to drink. He kept giving him this water a little at a time for two days. The third day Dr. Livingstone felt good enough to stand up.
He was cured.
