Drinking your own urine: A very special “healing juice” or just nonsense?

In the 80s and 90s, urine was considered a miracle cure. Why drinking it makes no biological sense – and what is really behind it.

The “very special juice” – a hype between longing for nature and biology

Looking back at the health movements of the 1980s and 1990s, one encounters phenomena that seem almost impossible to comprehend today rationally. One of the most prominent examples is so-called urine therapy. Millions of people experimented with drinking their own urine – a practice promoted in self-help books, talk shows, and alternative health circles. The roots of this trend reach further back. In 1944, the British naturopath John W. Armstrong published his book *The Water of Life*, in which he presented urine as a universal remedy. In German-speaking countries, the idea received significant media attention in 1988 through journalist Carmen Thomas and her book *A Very Special Juice – Urine*. The social context played a crucial role: distrust of “chemicals,” a growing scepticism towards conventional medicine, and a yearning for autonomous, natural healing methods paved the way for this trend. The message was simple: one’s own “pharmacy” was free, personalized, and available at any time.

What proponents hoped to achieve

Proponents argued that urine contains hormones, enzymes, and “information” about diseases. They claimed that drinking it again could stimulate the immune system – a kind of natural mini-vaccination or biological recycling program.

These assumptions sound plausible, but are not scientifically proven. High-quality clinical studies demonstrating a therapeutic benefit of urine analysis do not exist.

The biological reality: What urine actually is

Urine is not a healing fluid, but an excretory product. In healthy adults, it consists of approximately 95% water. The remaining five per cent contains primarily:

1. Urea – end product of protein metabolism
2. Creatinine – a breakdown product of muscle metabolism
3. Uric acid is produced during the breakdown of purines.
4. Electrolytes – excess sodium, potassium, chloride
5. Residues of medications, alcohol, or environmental substances

The kidney functions as a highly complex filtration system. It regulates homeostasis – the chemical balance of the blood. Everything that ends up in the urine has been actively excreted because it is present in excess, unnecessary, or potentially harmful.

Why drinking urine is biologically absurd

1. Physiological idle

Drinking urine reintroduces substances into the body that were just excreted using energy. These substances re-enter the bloodstream and must be filtered again. This provides no additional benefit, but merely prolongs the excretion process.

2. Increased stress during illness

It becomes particularly problematic when medications are taken or metabolic products are excreted in elevated concentrations. Re-ingestion can further increase the concentration of these substances in the blood – a medically counterproductive cycle.

3. Evolutionary Biological Perspective

Over millions of years, the human body has specialized in efficiently absorbing nutrients and selectively excreting waste products. If recycling the substances contained in urine were advantageous, a corresponding recovery mechanism would have developed, similar to the reabsorption of glucose or water. The fact that the body possesses a clearly defined excretion pathway is biologically unambiguous.

The psychological component

Why did many users still report positive effects? A classic mechanism is at play here: the placebo effect. Consciously overcoming a strong disgust threshold reinforces the subjective perception of doing “something radical” for one’s health. Expectations and self-belief can indeed influence symptoms – regardless of the liquid’s chemical composition.

Historical context

The urine therapy movement was an expression of an era in which a connection to nature and alternative medicine were highly romanticised. It exemplifies a phase in which simple, natural solutions were sought as a counterpoint to an increasingly complex world.

Today, the prevailing view is that evidence-based medicine finds no reliable evidence for any health benefits of drinking urine.

Conclusion

Urine is the end product of our body’s highly precise cleansing process. Drinking it reintroduces excreted metabolic waste products – without any proven benefit and with the potential to further strain the body. From a biological perspective, this is not a healing system, but a cycle without added value. Therefore, the sobering conclusion remains: urine belongs only where it was meant to go – namely, in the toilet.
