I never imagined that plain water could have healing properties against allergic reactions! 
Last year I experienced what an allergic reaction is like. I took innumerable antihistamine medications, but still couldn’t get a grip on it. A friend recommended a very simple folk remedy. I didn’t trust it— I never thought that plain water could possess therapeutic powers.
Yet now I have convinced myself of its strength: boil 1.5 liters of water for 10 minutes over medium heat. I want to emphasize that the boiling time should be exactly 10 minutes (neither more nor less). Then allow it to cool, and drink it at any time, sip by sip. I was amazed when I discovered that I no longer sneezed, and my nose no longer became congested, even though I wasn’t taking medicines. As soon as I felt a scratchy throat sensation, I immediately began drinking my water.
In the first few days I even kept a bottle of it beside my bed at night, and woke up to drink it. This kind of water should be consumed for a long time — we will not harm ourselves; on the contrary – our nasal cavities will be cleansed.
Doctor’s commentary: In general, water is of extremely great importance for the normal functioning of a living organism: to maintain physiological functions, the human body circulates up to about 40 000 glasses of water over a lifetime, day and night. Under such circulation conditions, we need to consume 6 to 10 glasses of water per day (depending on environmental conditions). If anyone thinks that their body does not require that amount of water, they are very mistaken.
We should drink water throughout the day in small portions, and supply fluid to our body in the same way one provides fuel to a car. In Eastern folk medicine, boiling water is indeed used as a means of cleansing the body and as an immune modulator.
When using such water, the following must absolutely be taken into account: during boiling, chlorine and chlorine‑containing compounds break down, salts and colloidal particles precipitate; a sediment forms; the water softens; the number of volatile components decreases; microbes, bacteria and viruses that cause disease vanish from it. Therefore boiling does indeed purify water. But this process also has negative effects:
As a result of boiling, the structure of the water is disrupted — it becomes “dead”. The longer we boil water, the more lifeless it becomes.
During boiling, due to evaporation the concentration of salts in the water increases; consuming such water raises the risk of kidney‑stone pathology, joint diseases, and atherosclerosis.
In boiling, chlorine may enter into reactions with other organic compounds and form substances harmful to the body. Researchers conclude that if a person constantly uses tap‑water that has been boiled, their immune system may decline. It is better to use spring water (source water) for boiling, one that does not contain chlorine. In that case the risk of harm to the body is minimal. Nonetheless, despite this, I still would not advise becoming obsessed with this method for the long term, because even spring water after boiling loses its initial structure.

Expanded Explanation & Commentary
The idea that “plain water” could act as a therapeutic agent against allergic reactions may sound surprising, but when viewed through the lens of physiology, detoxification and folk medicine practices, it starts to make some sense — albeit with caveats.
What the remedy suggests
You boil 1.5 liters of water for exactly 10 minutes on medium heat.
After boiling, you let it cool and sip it slowly, throughout the day or whenever you feel the onset of allergy signs (such as a scratchy throat).
Over time (you mention “for a long time”), you continue drinking this water, and you observed that sneezing stopped, the nose ceased to feel congested, and you required no antihistamines.
You also kept a bottle next to your bed, ready to sip during night awakenings, showing a strong personal commitment and belief in the remedy.
What folk/traditional medicine may say
Indeed, in many Eastern folk‑medicine systems (and some integrative/holistic approaches) boiling or heating water is considered not just for sanitary purification, but for altering the “state” or “energy” of the water, making it more “digestive”, more “cleansing”, or more “immune‑modulating.” The commentary included says that such boiled water is used for body cleansing and immune‑modulation. The doctor’s commentary emphasises that water is absolutely essential for life, for circulation of fluids, for supporting physiological functions, and that daily intake of 6‑10 glasses is necessary. The analogy of water as fuel for the body is apt.
Scientific / physiological considerations
Boiling water is certainly effective for eliminating many pathogenic microorganisms: bacteria, viruses, many protozoa. The processes described — removal of chlorine, precipitation of salts and colloids, sediment formation, softening of water — are partially correct in a broad sense (though some details may be oversimplified). The commentary also acknowledges that there are potential negative aspects: over‑boiling may “kill the structure” of water (from a folk or subtle‑energy perspective), high salt concentration due to evaporation might predispose to kidney stones or joint issues, potential formation of harmful by‑products from chlorine reacting with organics.
From a modern medical standpoint:
If you have an allergic reaction, one of the key issues is your immune‑system releasing histamines, causing sneezing, itchy or watery eyes, nasal congestion, scratchy throat, etc. Conventional treatment includes antihistamines, avoidance of allergens, sometimes nasal corticosteroids, immunotherapy.
The remedy you used appears to have helped you personally, possibly by improving your hydration status, improving general metabolic/circulatory/immune function, reducing overall stress on your system, and possibly by improving mucous membrane function (nasal, throat) via good hydration and “cleaner” water intake.
Good hydration alone is known to support mucociliary clearance in the nasal passages, to reduce dryness, support immune barrier function, and reduce the severity of allergic symptoms in some cases (though evidence is not strong that it replaces antihistamines).
Drinking water of good quality (filtered or boiled) ensures minimal contaminants, fewer heavy metals/microbes, which could reduce irritant load on the body and possibly lower baseline inflammation or immune activation.
Why you might have seen improvement
Your consistent ingestion of this boiled water likely improved your hydration, which is beneficial for allergy symptoms (thin mucus, improved clearance, less congestion).
The sense of “cleansing” from boiling may have reduced your exposure to minor irritants in your drinking water (chlorine, microbes), thereby lowering your baseline immune activation burden.
Taking the liquid reliably (every time you felt a throat scratch) signals a behavioural pattern: you acted early in the allergic process, likely reducing escalation of the symptom cascade.
There may also be a strong placebo / expectation effect: your belief in the remedy could itself modulate your immune response or perception of symptoms (the mind‑body connection is real).
Your dosage and commitment (a bottle by the bed, initial discomfort prompting immediate sipping) shows you took it seriously and made hydration and water‑quality a priority — which in itself is good health behaviour.
Important cautions
While this remedy appears to have worked for you, it is anecdotal, personal, and may not generalise to others. Allergic reactions range from mild (sneezing, watery eyes) to severe (anaphylaxis) and should always be managed under medical supervision when moderate‑to‑severe.
Boiling water is excellent for purification, but the commentary correctly notes risks: if you over‑boil, or boil tap water with high minerals repeatedly, you may concentrate salts, increase risk of kidney stones, joint issues, atherosclerosis. Also, repeatedly boiled water may lose certain trace volatile compounds (though the idea that water “loses structure” is more a folk energy concept than a scientifically measurable effect).
If your water comes from a chlorinated municipal source, boiling will remove free chlorine but may not remove other chemical contaminants (some of which might concentrate). If you have a spring or gravity‑fed clean source, better. If you rely on heavily treated tap water with organics, you might consider using a good filter before boiling.
If you experience any worsening of symptoms — increased sneezing, shortness of breath, wheezing, skin rash, swelling — you should seek medical care immediately. Don’t rely solely on hydration or traditional water methods for serious allergic responses.
If you have kidney disease, are on fluid‑restrictive diets, or have risk of kidney stones, you must be mindful about total fluid intake and the mineral content of your water.
Consistency matters: you did this “for a long time,” you were disciplined — simply trying it once may not produce the same effect.
Practical recommendations for using such a water‑based remedy
Choose a good water source: ideally spring or well water with low chlorine content, or municipal water that has been pre‑filtered to reduce chlorine and organics.
Bring ~1.5 litres of water to a medium boil, and maintain exactly 10 minutes of vigorous boiling (not just simmer), to ensure adequate microbial clearance and breakdown of chlorine and some volatile compounds.
After boiling, allow the water to cool to comfortable drinking temperature, then sip slowly throughout the day. You might carry a bottle with you, keep one near your bed, drink when symptoms start (e.g., scratchy throat, nasal tickle).
Maintain good overall hydration: aside from the boiled water, drink adequate fluids (6‑10 glasses/day is the general guideline, but
