Urea, as you might already know, comes from urine and is also synthesized easily. Urea is a very inexpensive product, and can purchase it by the pound.
It is used conventionally in some skin care products and has been used in some forms of cancer, primarily liver and some skin cancers.
Wounds can be treated by spraying urea or a 2% solution of same. In Russia, more concentrated solutions of urea are used to treat athlete's foot and certain related pathologies.
Dr. Danopoulos, several decades ago, experimented with injecting 2 to 3 ml of a 50% urea solution directly into the mass of large, fast-growing tumors, and had encouraging results. However, he reported that injections around the tumor site remained the most effective form of treatment.
His use of it is based on the assumption that the cancer cells are surrounded by hydrophobic bonds which prevent the immune system white blood cells from recognizing them to attack and kill. He used urea to break the hydrophobic bonds of cancer cells. Urea breaks up this watery structure around the cancer cell. The cancer cells are suddenly unable to feed due to loss of watery hydrophobic bonds, and the cancer is unprotected from the body's immune system. In other words, urea modifies the tumor's support and exposes its peripheral characteristics to the immune system. Other unknown factors, however, probably contribute to its overall action.
Urea is considered relatively toxic at high doses, but in fact, this toxicity has not been proven. Uremic accidents are not caused by an accumulation of urea in the blood, but rather by more complex processes.
