destroy cancer, did not prove to be correct. Sec- ond, it does not appear that Beard’s theory of the trophoblast, although evidence indicates it to be true, was needed to bring the laetrile through to a useful method of treatment. The only factors in common seemed to be that both were keyed to enzymes as being involved in the treatment of can- cer. But beta glycosidases and rhodanese are quite different than Beard’s pancreatic enzyme. In 1977, the publishers of one of the most popular dictionaries in the world contacted the McNaughton Foundation, and asked them to de- fine the meaning of the word, “laetrile.” Here is the definition they provided: “Laetrile—(Lay-eh-tril) “Basic Ingredients: An organic aglycone or non-sugar protein combined with a cyanide group and carbohydrate in glycosidic linkage to form a single tightly bound molecule. “Chemical formula: Since laetrile is a col- lective name for a group of chemically related compounds, the generic name for which is nitriloside, it cannot be given a specific chemi- cal formula. A well-known analogy is digitalis which represents a general group of chemically related compounds to which no specific formula can be assigned. “Etymology: Originally used as a shortened term for a laevo-rotatory glycuronic nitrile. Its meaning has been expanded to represent a shortened term for any laevo-rotatory gluco- sidic or glucuronic chemical compound con- taining an aglycone and a tightly bound (CN) grouping.”—McNaughton Foundation. That definition will help the medical research- ers who use this present book. It is questionable if it helped the poor folk who were trying to revise their dictionary.
The next step for Krebs, Jr., was to further refine the extract until what it amounted to was purified amygdalin. Only then could the cyanide remain safely bound in its compound until it reached the hydrolytic enzymes, which would break it apart at the cancer sites. The process for extracting the laetrile from the apricot pits is not a secret. Here is the formula: “The first step in the present production, which is from natural materials, is to grind the apricot seed or kernel; then it is defatted with a cold solvent, such as ether, hexachlorine, or other such substance, and the solvent is driven from the remaining ground pulp, and a com- pletely fat free powder which is partially soluble in water is left. “The laetrile (amygdalin) in this powder as
well as the sugars are also soluble in alcohol, and laetrile happens to be selectively soluble in boiling alcohol (about 40 times greater than cold alcohol). The fat free powder is then added to boiling alcohol where laetrile is extracted from the powder and then the materials are filtered. “The filtrate that remains is put in a freezing cabinet, or refrigerator or cold room, where the temperature is brought down to about 10 de- grees Centigrade. The crystals of laetrile pre- cipitate or fall to the bottom of the flask be- cause in cold alcohol the material is insoluble. “Now these crystals are recovered and the process of recrystallization is repeated a num- ber of times, depending on whether the mate- rial is to be used for oral purposes or for injec- tion. “When the chemicals are dried the first time, they have a chemical purity of about 99.7 or 99.8 percent pure. For oral purposes, it is re- peated twice.”—Ernst T. Krebs, Jr., address to the San Francisco Vegetarian Society, 1974. Throughout their work, neither the Krebs, nor any other laetrile worker tried to patent or control any of the various processes. It was made avail- able to any physician, laboratory, or research group—anywhere in the world.
In 1949, Krebs, Jr., injected himself with the first human shot of the purified substance. He had researched the matter enough that he had not the slightest concern that it would poison him.
Had he had cancer—anywhere in his body,— the enzymes would have triggered the lethal re- lease of cyanide at the site of the tumor while his noncancerous tissue would have been pro- tected by rhodanese. If he had no cancer, the body’s natural processes would slough off the laetrile naturally.
That is why it is good to eat apple seeds, apricot kernels, etc. They help eliminate can- cer in its early stages, years before it reaches the critical final phase. (But, of course, other changes must also be made in the diet and lifestyle, if one wants to avoid cancer.)
It was at this time that Krebs, Jr., gave the substance the name “laetrile.”
In 1950, the first laetrile treatment of hu- man cancers, always to terminal patients, was given intramuscularly—and involved only 10 milligrams. That was but a fraction, compared to the size of doses given today. A small dose was given back then, because the amount of cya- nide rhodanese which the body could tolerate was not yet known. Decrease in pain always occurred but, because of the small dosage, death always
