"A number of years ago the late Dr. Weston A. Price Cleveland, Ohio, internationally known for his work relating to the cause of dental decay, came to Barre to discuss with me my years of study of native Vermonters living close to the soil, and of Vermont folk medicine. He had just returned from a trip to Peru, where he studied and photographed the condition of the teeth of individuals living at high altitudes in the Andes Mountains. He had been all over the world studying the teeth of primitive peoples, in an effort to learn causes of dental decay, and wished to add to his studies dental conditions of people living in high altitudes.
He himself was unable to go higher than 12,000 feet, but he learned about individuals living at 16,000 feet. He arranged for some of them to be brought down to 12,000 feet so he might study them and photograph their teeth.
While he was working he chanced to notice that each individual carried a little bag, of which all seemed to be partictilarly careful. Out of curiosity lie looked into the bags and discovered that they contained kelp. When he asked where they had got kelp so far from the ocean, they said calmly that they got it from the ocean. This surprised him since it took a month to make the trip to and from the coast What did they use the kelp for? To guard the heart, they explained to him.
Soon after Dr. Price visited me a patient who had had several heart attacks came to my office to have his ears inflated. He came on a Friday and I asked him to return on the following Monday. He said he did not know whether he could make a second visit because, in climbing the one flight of stairs to my office, he had been obliged to stop and rest three times because of pain in his heart. He said that he was obliged to remain quiet throughout each morning so that it would be possible for him to be moderately active in the afternoon and evening.
I gave him some 5-grain kelp tablets with' instructions to take one tablet either before, during, or after each meal, whichever he found most convenient.
The following Monday he walked into my office and, holding out his wrist, asked me to take his pulse. It was 72 for the minute count. I then asked why he had wanted me to take it. He said that since taking the first kelp tablet he had been completely free from heart pain. He had walked up the stairs on this second office visit without having to stop and rest. I had him continue taking one 5-grain kelp tablet at each meal, with the result that he became much more active than he had been.
A minister and his wife who lived in California were visiting at our home. During the course of conversation an expression indicative of severe pain came across his face, and he clutched his heart region with his right hand. When were alone I asked him if he had suffered pain in the heart and he said he had. Occasionally he would have this momen tary heart pain and he was quite concerned about it.
I told him about Dr. Price's experience with the Peruvian natives living at 16,000 feet and gave him some kelp tablet with instructions to take one tablet at each meal. I learned later that this ended the attacks."
