Strange
I am 62 years old and have never taken any homeopathic medicine ever. I have been protected "against every disease going" for all those years.
Let me tell you of the history of homeopathy, written in a way that homeopaths would never accept, because it is the truth.
It was begun by a 17th century doctor called Hahnemann. His idea was that symptoms were the body's way of stopping a disease. He then decided to increase the severity of symptoms, to fight disease even harder. That is the "like attacks like" part of homeopathy, in that something increasing a symptom fought the agent that caused the symptoms. At the time, medicine was very primitive, but one area was relatively well developed and studies - the science of poisons. Hahnemann had a good range of poisons to increase different symptoms.
He started dosing his patients with these poisons, to boost the relevent symptoms, and thus fight disease. He discovered that a high dose of poison increased the chance of his patient dying. Surprise, surprise! So he started diluting the poison, and found that the weaker the poison, the better the chance of the patient surviving. Even bigger surprise!
This led to something utterly and totally ridiculous. Homeopaths, the followers of Hahnemann, now dilute their 'remedies' to the point of nonsense. Often to the stage where there is no active ingredient - not one atom - left in the remedy. They firmly believe that the more dilute the remedy, the better it is. This is the direct opposite of what science has shown, where an effective remedy works better with a stronger dose, at least up the the point where it becomes toxic.
Homeopaths try to get around this conflict with good science by postulating that water has a 'memory' and remembers the agent that was once in it, and the 'memory' carries out the therapeutic action. This hypothesis is quite contrary to what science knows of water. There is no indication that water can have a 'memory'.
However, in the end, only empirical, rigorous, scientific testing can show if a method works or fails. This has been done so many times, that a 'metastudy' could be carried out, comparing homeopathic remedies to placebo (sugar pills), using the results from 110 different rigorous studies.
Homeopathy and The Lancet
The end result showed homeopathy is exactly as effective as placebo. In other words, rather than homeopathic remedies that cost you a lot of money, just take a sugar pill. It is every bit as good.
