Homeopathy: What should you know before trying it?

What is homeopathy?

The word “homeo” and “pathy” mean “similar disease” in Greek. This signifies that homeopathy is based on the principle of similarity, or the concept of “treating like with like.”

Originating in Germany in the early 19th century, homeopathy is a medical system founded on the idea that “like cures like.” This means that a substance that causes symptoms in a healthy person can potentially cure those same symptoms in an unwell person if given in very small doses. This minimal dose is thought to stimulate the body’s natural healing mechanisms.

How did homeopathy come about?

This concept was introduced by Dr. Samuel Hahnemann, who discovered that quinine bark, which causes fever in a healthy person, could reduce fever in malaria patients. From this observation and subsequent research, Dr. Hahnemann formulated a theory based on treating diseases with substances that cause symptoms similar to the illness in a healthy person. 

Therefore, homeopathy is built on two main principles: the law of similars and the concept of ultra-dilution. According to the law of similars, a substance that can cause disease symptoms in a healthy person may help cure the same symptoms when given in a much smaller dose. For instance, proponents claim that bee venom, which typically causes redness, swelling, and pain, can be used in diluted form to relieve symptoms of similar conditions, such as certain skin inflammations.

To avoid toxic effects and purportedly increase the therapeutic benefits, the active substance is diluted repeatedly in a solution of water or alcohol, with vigorous shaking (referred to as “dynamization”) between each dilution. This process is thought by homeopaths to transfer the “essence” or energy of the original substance into the final remedy, even though, at high dilutions, it is unlikely that any molecules of the original substance remain.

Homeopathic remedies can be made from various sources, including plants, minerals, and animal products. The preparation is labeled with the name of its original source in Latin, followed by its dilution level, such as Arnica 9 CH granules, where “CH” indicates the centesimal dilution scale.

Which conditions does homeopathy address?

Homeopathy is commonly sought out for a range of conditions, both acute and chronic. Some illnesses people use homeopathy for include:

• Acute conditions: Colds, flu, sinusitis, fever, diarrhoea, bruises, and headaches.
• Chronic conditions: Allergies, eczema, asthma, arthritis, menstrual and menopausal symptoms, sleep disorders, and fibromyalgia.

Supporters argue that homeopathy can help reduce anxiety and stress, or even boost the immune system, particularly as a preventive measure before the winter season.

What are the scientific and regulatory perspectives on homeopathy?

Scientific research on homeopathy has been mixed and often criticized for methodological flaws. Most rigorous studies and systematic reviews conclude that homeopathy is no more effective than a placebo. For example, a comprehensive review by the Australian National Health and Medical Research Council in 2015 concluded that there is no reliable evidence that homeopathy works for any health condition.

Supporters often point to smaller studies that show positive effects. One such study, the EPI3 study conducted in France in 2011, found that patients using homeopathy for musculoskeletal pain required fewer anti-inflammatory drugs than those using conventional treatments. However, critics argue that such results are difficult to interpret due to the lack of robust controls and potential biases in study design.

In the United Kingdom, the National Health Service (NHS) ceased funding homeopathic treatments in 2017, claiming that they provide no scientific benefit beyond a placebo effect. Following this, the National Institute for Health and Care Excellence (NICE) recommended against the use of homeopathy for any health condition. Despite this, a small percentage of the population continues to use homeopathy privately, often turning to practitioners trained by the Faculty of Homeopathy, an organization that advocates for its practice.

What are the risks and limitations of homeopathy?

Most homeopathic remedies are highly diluted and are generally considered safe. However, potential risks include allergic reactions, toxic effects from improperly prepared products, and the danger of delaying necessary conventional treatments. 

Users should consult healthcare professionals before using homeopathy, particularly in vulnerable groups such as pregnant women, breastfeeding mothers, and young children.

One of the primary concerns is that patients may forgo evidence-based treatments for serious conditions in favour of homeopathy, which could lead to worsening of their health.

While it may be used as a complementary therapy, a homeopathic treatment should, under no circumstances, replace surgical interventions or be used as a substitute for conventional treatments for serious or chronic conditions.

It is not effective for treating certain illnesses or conditions such as life-threatening acute infections, heart attacks, severe digestive issues, diabetes-related complications, or irreversible diseases.
