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.


Urea can help with the following


Cystitis, Bacterial Bladder Infection

Urea can be used to treat urinary infections without renal lesions, such as pyelonephritis or glomerulonephritis, as urea possesses interesting bacteriostatic and antibacterial activities [Urology, vol. 86, 1961]



Edema (Water Retention)

Urea is a direct diuretic, meaning it can increase diuresis by boosting the function of the renal epithelia. Urea can be taken internally: 1 to 2gm per day are used as a treatment of water retention and related problems (such as swollen face, swollen fingers in the morning, headaches, premenstrual water retention, watery dreams, etc.).

Tumors, Malignant  

Liver Cancer

In 1954 a Greek physician, Dr. Evangelos D. Danopoulos, reported discovering that urine had anticancer properties. After years of research, he identified urea as the active anticancer agent in urine. Urea is the end product of protein metabolism and is the main substance excreted in the urine.

Dr. Danopoulos reported the results of oral administration of urea in the treatment of patients with liver cancer. In this study eighteen patients (eight with primary tumors and ten with metastatic liver tumors) were given 2 to 2.5gm of urea four to six times daily. Patients with more than 30 to 35% of their liver involved were not allowed to participate. With this treatment, the patients had an average survival of 26.5 months, five times greater than usually expected.

In a follow-up study, eleven patients with primary liver cancer and seventeen with metastasized liver cancer were treated with 10 to 15gm of urea daily. Again, excellent results (25.6 months of average survival) were obtained.

However, other researchers found that urea has no activity on secondary liver cancer associated with colon cancer (colon-liver metastasis).


Basal Cell Cancer

In 1974 Dr. Danopoulos published a paper on the use of urea in the treatment of basal cell and squamous cell skin cancers. Initially he injected 2 to 6 ml of a 10-percent urea solution around the tumor site every other day. After about two years of experimentation he discovered that applying sterilized urea powder directly to the surface of ulcerating tumors, following the injections, increased the beneficial effects.

Refers to the various types of malignant neoplasms that contain cells growing out of control and invading adjacent tissues, which may metastasize to distant tissues.

Immune System

A complex that protects the body from disease organisms and other foreign bodies. The system includes the humoral immune response and the cell-mediated response. The immune system also protects the body from invasion by making local barriers and inflammation.

White Blood Cell

(WBC): A blood cell that does not contain hemoglobin: a blood corpuscle responsible for maintaining the body's immune surveillance system against invasion by foreign substances such as viruses or bacteria. White cells become specifically programmed against foreign invaders and work to inactivate and rid the body of a foreign substance. Also known as a leukocyte.
