What Is Homeopathy?
Homeopathy is an alternative philosophy that believes highly diluted substances have the ability to stimulate the body to heal itself. It is largely based on the following core homeopathic beliefs:
- A substance that produces a certain set of symptoms in a healthy person has the power to cure a sick person manifesting those same symptoms. In homeopathic medicine this is called Law of Similars, or like cures like.
- Diluting a remedy makes it more powerful. In homeopathic medicine this is called Law of Infinitesimals.
- A homeopathic treatment is designed to facilitate a release of the illness. Allopathic treatments (traditional medicine), according to homeopathic beliefs, supresses the symptoms and drives the illness back into the body.
The following is an example of the beliefs: the substance ipecac causes vomiting. According to the first and second laws of homeopathy, significantly diluted ipecac would potentially treat vomiting. The more ipecac was diluted, the more effective it would become.
Over the past few decades, a large number of studies investigating the effectiveness of homeopathy have been published. Despite the occasional favorable result, there is no meaningful evidence that homeopathic remedies are effective for any condition.
The Practice of Homeopathy: Constitutional Homeopathy vs. Disease-Oriented Homeopathy
Constitutional (or classical) homeopathy follow traditional homeopathy philosophy. Constitutional homeopaths choose a product based on the symptom picture or pattern of a person, including psychological, emotional, physical, and hereditary factors. A simplified form of homeopathy called disease-oriented (or symptomatic) homeopathy has also been developed. In this form, the remedies are matched with specific diagnosed diseases.
Both types of homeopathy have been studied scientifically, although disease-oriented homeopathy has received more attention for the simple reason that it is easier to study. Neither method has been proven effective.
As mentioned above, homeopathy requires that a chosen mineral, plant, or animal substance be significantly diluted in a solution to create a homeopathic product. The products used in the dilution and the creation process are outlined in Homoeopathic Pharmacopoeia of the United States (HPUS). The FDA requires companies to follow these guidelines to sell products. The HPUS was developed by the carefully recorded observation of symptoms caused by the included natural products.
A small amount of the mineral, plant, or animal product is added to a dilution material, such as alcohol. This combination is then added to more dilution material. These steps are repeated until the desired dilution (or potency) of 6c, 12c, or 30c is reached. These products are so dilute that little or none of the original substance is left. According to principles of homeopathy, each dilution makes the product stronger. The process is called potentization. Sometimes homeopathic products are made with substances that are insoluble. In this case, they are ground up, mixed with lactose, and then made into a homeopathic product. Homeopathic products may be delivered within small white lactose pills, in liquids, or creams that are used externally.
In addition to standard homeopathic solutions that use unrelated substances that happen to produce a similar symptom, there are two forms of homeopathic solutions that use substances specifically related to the condition:
- Isopathic products are made from the actual substance that causes the condition. For example, a homeopath may use a remedy prepared from cat dander to treat cat allergy.
- Nosodes are made from infected animal tissues or bodily secretions. Here, a homeopath may dilute ground up, tuberculosis-infected glands from a cow to create a homeopathic product for human tuberculosis.
Nosode homeopathic products are sometimes compared to vaccinations. Superficially, the theory of homeopathy may sound similar to vaccination where the introduction of an altered virus is used to decrease the risk of an infection by the same virus. However, this comparison is inaccurate and misleading. Unlike homeopathic products, vaccinations contain measurable amounts of substances that produce measurable stimulation of the immune system. The benefits of vaccinations are also backed up by an overwhelming amount of research, unlike nosodes.
Scientific Evaluation of Homeopathy
Despite its widespread use in some countries, virtually no scientific authority takes homeopathy seriously. There are several reasons for this intense skepticism, but the most important focuses on a basic fact of chemistry. Simply put, there is nothing material left in a “high-potency” homeopathic product; some force of nature unknown to modern science would have to be involved for homeopathy to work.
Here is why. In the process of making a 30c homeopathic product, the original substance is diluted by a factor of one part in 1030. This is such an enormous dilution that none of the substance could possibly remain. The so-called “highest potency” homeopathic products, therefore, contain no active ingredients. Low potency remedies (6s, 12c) do contain a measurable amount of substance, but these remedies are supposedly less effective than the high potency forms. It goes against basic chemistry principles that a solution with no product is stronger than a solution with a small amount of the product.
There are other practical problems with homeopathy as well. For one, there is no reason to believe that a substance that produces certain symptoms when taken as a whole should cure a disease that just coincidentally happens to possess the same symptoms when it is taken in diluted form. This hypothesis appears too tidy and perfect to truly reflect the messy world of human illness.
Furthermore, the detailed symptom pictures upon which constitutional homeopathy are based are far too specific and personal to offer any likelihood of universal truth. For example, the homeopathic remedy sulphur is said to be useful for people who have red lips, stooped posture, and a tendency toward untidiness in personal affairs. A small selection of other supposed characteristics of this remedy include mid-morning hunger and a tendency for increased discomfort of whatever physical symptoms they may be experiencing between 10:00 and 11:00 a.m. and after exposure to cold air or motion.
Since basic principles of medical science are at odds with the foundational theory of homeopathy, what should be made of the occasional randomized controlled trial that appears to show benefit? Do flaws lie in medical science or with completed research? It is unlikely that homeopathy operates through some mysterious new force that science has failed to discover. It is far more likely that the positive outcomes were the result of flawed trials that produced unreliable results.
What to Expect From a Session With a Homeopathic Physician
To understand how a visit to a homeopathic physician works, consider the following imaginary scenario: Sam has felt tense and nervous for months. His workload has increased dramatically since he started a new job last year. He has not been sleeping well, and he has lost weight. His conventional physician recommends a stress-reduction program consisting of gentle exercise and regular relaxation, but he decides to try classical homeopathy instead.
His initial homeopathic consultation consists of a lengthy interview. The homeopath makes note of small nuances that would not be considered important by a conventional physician. Aside from his nervousness, Sam has been suffering from frequent nosebleeds, easy bruising, dry cough, hoarseness of voice at times, and occasional diarrhea and stomach aches.
The doctor asks whether cold drinks relieve his stomach pain, and Sam nods. Next, the homeopath asks him several questions about his family history, personality, and psychological tendencies. Sam says that he is outgoing and friendly and likes company. “You wouldn’t happen to be afraid of thunderstorms,” she asks, and Sam answers that, in fact, he is. The interview continues for an hour.
Based on her analysis of Sam’s “constitution” as revealed by close questioning, the homeopath carefully selects a homeopathic remedy that matches, based on the classic description in the Homeopathic Materia Medica . This text reports the symptoms to be expected when taking an overdose of various substances. These descriptions are complex and elaborate, covering physical and psychological symptoms that developed in the people who undertook the experiment; taken together, they represent the “symptom picture” of the remedy.
Sam’s homeopath chooses the remedy Phosphorus , because its symptom picture matches him closely. He is told to take the remedy for 3 months. During the period of treatment, he is advised to avoid the use of any pharmaceutical drugs, medicinal herbs (such as St. John’s wort), or foods with drug-like properties (eg, coffee) because they have properties that might “antidote” (counteract) the effect of treatment. At the end of 3 months, he is advised to call for a follow-up visit, at which point he may be given a new remedy to treat “deeper” problems that may emerge.
Note : This description applies to practitioners using classical or constitutional homeopathy. Many alternative practitioners use homeopathic remedies to treat particular diseases and use herbs and supplements in conjunction with them.
As we shall see in subsequent pages, some studies have reported positive results. However, rigorous studies have failed to find it effective, and overall, the body of supporting evidence is too weak to overcome the reasonable presumption that it cannot work.
Homeopathic Treatments by Condition
Homeopathy has been used traditionally to treat virtually all conceivable medical problems. However, this database is limited to conditions for which at least one homeopathic remedy has been evaluated in a double-blind, placebo-controlled trial.
