While it is true that urine can contain tumor antigens, there is no evidence to show that drinking, massaging with, bathing in, or any other application of urine will stimulate antibody production or in any way fight off a cancer. The quantities of substances, including tumor antigens, present in urine are typically minuscule compared with those already present in the blood and elsewhere in the body. The bottom line is that drinking urine has no known medical benefit.

Contrary to the claims of alternative therapies that say urine has curative powers, urologists and nephrologists say that the increasing concentration of toxins will quickly do more harm than good. The American Cancer Society states that "[n]o well-controlled studies published in available scientific lite...."

However, some research has been done in this regard...

Patent US6410059 - Pharmaceutical composition containing cow urine ...

Patent US6896907 - Use of bioactive fraction from cow urine distill...

And this is my explanation...

The patent says…the applicants thought of utilizing cow urine, which is not MICROBICIDAL but when present with a drug or active molecule, enhance its activity and availability (bioenhancers). The present invention was the result of planned experiments to provide a novel method for improving activity and bioavailability of antibiotics, drugs and other molecules using ‘cow urine distillate’ in different formulations.

It is similar to saying methi seeds ‘enhance’ the diabetic drug performance but they don’t actually act as drugs themselves.

THE PAPTENT CLEARLY SAYS gaumutra IS NOT A MEDICINE BUT JUST A BIO-ENHANCER.

OH, YES IN LAB CONDITIONS SEVERAL THINGS HAPPEN WHEN ONLY TWO THINGS ARE TAKEN INTO ACCOUNT BUT IN ACTUAL COMPLEX HUMAN BODIES DIFFERENT REACTIONS might take place.

Gaumutra might contain bioenhancers but they also contain several toxins too that the cow’s body is trying to excrete. A distillate is a liquid which is condensed from a vapor during distillation and removes microbes and other substances that are harmful.

The best possible way to use bio-enhancers is to extract them, purify and use them.

Raw ‘gaumutra’ as it is excreted by a cow is harmful. }.

Cow's urine poisoning in Nigeria. Experimental observations in mice.

Gaumutra has no benefits in cancer therapy. It is harmful in its raw form.

Please don’t take it while undergoing chemotherapy as your immune system will be already under severe stress and taking raw gaumutra can cause more severe infections.

There are over 200 types of cancer. Which cancer exactly does cow urine cure?  So far, there is no definite "cure for cancer" because cancer isn't one disease to begin with. 
 There's a "patent" for cow urine's efficacy in treating cancer floating around on the web. But a patent does not mean pharmaceutical efficacy. The patent was was based on testing on mice, not humans. Unless there is pharmaceutical testing with human trials approved by a competent regulator such as the US FDA or the Indian Drug Controller General would be valid. 

What is disturbing is a study that reveals how cow urine, being administered to mice can cause "significant side effects, including convulsion, depressed respiration, and death." Cow's urine can also be a source of harmful bacteria and infectious diseases.

Q: Do white spots on nail appear because of Zinc deficiency?

Krishna: No! Some even say it is because of calcium deficiency. That is also not true.

These white spots in fingernails are called “leukonychia” and are very common and harmless most of the time. Usually the white spots simply are a sign of some past injury to the matrix (base) of your nails. By the time the white spot shows up (about six weeks after the injury) you’ve probably forgotten all about banging or knocking your fingers. Sometimes, the injury can stem from a manicure that put excessive pressure on the base of the nails. White fingernail spots also can be a sign of an allergic reaction to nail polish or nail hardeners and, sometimes, are a symptom of a mild infection.

Common sources of injuries to nails include:

• shutting your fingers in a door
• striking your fingers with a hammer
• hitting your nails against a counter or desk

Whatever the cause, white spots on fingernails are temporary and will grow out as your nails grow. However, it can take more than eight months for nails to grow out completely so the spots may be around for a while.

Sometimes, a change in the appearance of your nails does indicate an underlying disease, but these changes would be more dramatic than just the occasional white spot. Nails that turn completely white, for example, can indicate liver disease, but by the time this happens, you probably would have other symptoms.

Less common causes for white spots on nails include: heart disease, bad health, kidney failure, psoriasis or eczema, pneumonia and arsenic poisoning. However, these reasons are very rare and without investigation, don't come to a conclusion on your own. 

Q: Black magic is science. It is here since ancient times. Why do people like you dismiss it as superstition?

Krishna: Oh, my! What am I hearing and reading?

Some people say superstitions are science. Some say black magic is science. Some say pseudo-science is actually science. Some say religion is science.  

We are actually a bunch of ignorant people despite studying in schools, colleges and universities.

Pseudoscience by definition is a belief, claim, or practice that is demonstrated as scientific but does not fall under the heading science. Lacking support and evidence makes pseudoscience not considered to be science as it is not valid under the scientific method. Beliefs, certain cultural, and traditional practices can be considered pseudoscience. Pseudoscience is often vague, exaggerated and lacks the ability of evaluation. Good science on the other hand, is one that follows the scientific method checklist. Good science could be measured, tested, evidence based and therefore it is valid and reliable. 

While good science works with facts, pseudoscience works with opinion. Good science is always peer reviewed prior publication, while pseudoscience is almost never checked and is simultaneously published for the public.  Pseudoscience is false science that with acquired skills makes the public fall for it and start believing in it as it targets one’s emotions and needs. 

Black magic works only on mentally weak people, not because it actually works but because it effects their psychology. When you think it is working, you get scared, worried, get depressed and think everything negative happening in your life is because of it.

If somebody can control your mind and life like that it is because you showed them your weaknesses and vulnerability. Fear, uncertainty, greed and jealousy and of course ignorance are these deficiencies in your meantal make up.

Just a few mantras, lemon and chillies or some kumkum and haldi or a doll or a few neem leaves cannot do any harm to anybody. A person who cannot control his own destiny cannot do any harm to others. No person has such supernatural powers as to cause harm to others just by wishful thinking. Realize that. Then nothing or nobody can effect you.

The nocebo  effect has been seen in clinical trials. The opposite of the placebo effect, the nocebo effect can cause patients to develop symptoms when told they may be a side-effect of a possibly harmless drug. This may explain how a curse could have a real effect.

Some people try to earn money by cheating people and telling them they can do black magic on others. If you are a sucker, you believe them.

Science doesn’t accept black magic because there is no such thing actually. It just is a superstition. Your baseless belief that is effecting you mentally because you are not strong. So stop believing in it if you don't want it to work psychologically.

A challenge:  Black magic, no matter who resorts to it, cannot effect me in any way. Why? Because I know it doesn't work and therefore I am not at all worried. It doesn't effect me psychologically. Nobody, literally nobody, can do black magic to me. 

Never has an empirical scientific discovery been deemed wrong and replaced by a more convincing mystical explanation or a misconception. On the contrary science replaced myths, mystics, mythologies, magic, mysteries and misconceptions. 

Science is the most accurate understanding of the universe. If it found and says black magic is a superstition, it has evidence in this regard. 

Black magic is not science.  It is another misconception and definitely a superstition because tehre is no evidence of its actual working.
