Intriguingly, a 2012 National Health Interview Survey reported that an estimated 5 million adults and 1 million children in the U.S. turned to homeopathy within that year. Yet, despite its popularity, many people may not fully comprehend what homeopathy is or how it operates. Homeopathy has spread across the globe since its origin in Germany over two centuries ago. In this article, we will discuss the heart of homeopathy, examining how it works, its scientific support, the conditions it commonly addresses, and potential risks that should be understood.

What is Homeopathy?

Homeopathy, an alternative medical practice that came into existence in the late 18th century, operates primarily under two cardinal principles: "like-cures-like" and the "law of infinitesimals.” The first principle proposes that a substance that prompts symptoms in a healthy person can be used to treat similar symptoms when provided in a diluted form. The second principle, the law of infinitesimals, contends that the potency of a substance intensifies with its dilution. This belief implies that a substance, which can induce specific symptoms in its natural form, has the potential to treat these symptoms when diluted. It's worth noting that homeopathic products are usually established through "provings." Here, substances are given to healthy volunteers in concentrations capable of causing symptoms. The volunteers' experienced symptoms are then recorded to suggest potential therapeutic uses for these substances (3).

Despite the fact that homeopathy is based on principles and processes that have been proven to work, scientific research in this area has been relatively limited and many studies conducted have been deemed of low scientific quality. Critics often attribute the observed effects of homeopathy to the placebo effect, where improvement of symptoms can occur in the absence of actual medicine. Furthermore, it is argued that homeopathy tends to focus more on alleviating symptoms rather than treating the underlying causes. Given these complexities, the concept of homeopathy can be challenging for some to grasp logically due to its unconventional nature (3).

How Does Homeopathy Work?

Homeopathic remedies begin with substances derived from herbs, minerals, or animal products, which are then crushed and dissolved in a liquid medium, typically grain, alcohol, or lactose. This solution undergoes mechanical shaking and is then stored, resulting in what is known as the "mother tincture." Further dilutions are made with the liquid medium, leading to varying potencies of the tincture, represented as "x" or "c" - for example, a 1x or 1c dilution. The process of shaking, or "potentization," is believed to transfer the healing essence of the original substance to the solution. The diluted solutions are believed to have greater potency despite often not containing any molecules of the original substance.

Homeopathic remedies aim to stimulate the body's natural healing mechanisms, considering both the physical and psychological aspects of an individual's health. A diagnosis in homeopathy includes physical symptoms, current emotional and psychological state, and the person's constitution, which encompasses aspects such as creativity, initiative, and stamina. As a result, remedies are highly individualized. For instance, three individuals with the same ailment, like hay fever, may require three different remedies (4).

In practice, the remedies come in various forms, including sugar pellets, liquid drops, creams, gels, and tablets, and most are available over the counter at drugstores and health food stores. Dosages and duration of use can vary significantly based on the remedy and the individual's response. It's worth noting that during a homeopathic appointment, a series of questions about your mental, emotional, and physical health will be asked to best match and tailor the remedy for your symptoms (5).

Is There Any Evidence Supporting Homeopathy?

Homeopathic remedies, characterized by their unique principles, such as "like-cures-like" and the belief that dilutions increase potency, offer an alternative perspective to conventional medicine. These principles are viewed through a different lens by health organizations, who evaluate the evidence for their effectiveness using scientific standards of clinical evidence (6).

Notably, a comprehensive systematic review conducted in 2015 delved into the evidence from various systematic reviews examining the effectiveness of homeopathy across different clinical conditions. While high levels of confidence were not found for any condition, there was a notable instance where moderate confidence was found. The remaining conditions ranged in confidence levels from moderate-low to very low. These results indicate a need for further exploration and study into the effectiveness of homeopathy (6).

A remarkable aspect of these studies is the rigorous scientific criteria that they have to meet, creating a demanding context for homeopathic research. For instance, the 2015 comprehensive assessment of evidence by the Australian government’s National Health and Medical Research Council had stringent prerequisites, including studies with more than 150 participants and the highest rating of methodological quality, among other measures. Out of this rigorous process, 57 systematic reviews containing 176 individual studies were incorporated into the assessment.

The complexity of homeopathic principles, such as the dilutions rendering an "active ingredient" unmeasurable, poses considerable challenges to scientific investigation. Yet, it is this very complexity that has spurred recent research into the physical attributes of these homeopathic preparations. The goal is to understand if these preparations can be characterized in the future, providing a more comprehensive picture of homeopathy's potential (11).

Since the 2015 review, more systematic reviews have been conducted. Although these reviews met methodological quality, they did not substantially augment the evidence supporting homeopathy's effectiveness. This doesn't invalidate homeopathy but emphasizes the stringent criteria for the scientific evaluation of efficacy (6,7).

In essence, the classification of homeopathic alternatives by regulatory bodies such as the FDA is based on these high standards of clinical evidence. Homeopathy remains a subject of ongoing research and investigation, with a view to understanding its full potential and boundaries within these scientific criteria (11).

What Common Conditions Are Treated With Homeopathy?

Homeopathy is utilized for a vast array of health problems, including certain chronic conditions such as allergies, migraines, depression, chronic fatigue syndrome, rheumatoid arthritis, irritable bowel syndrome, and premenstrual syndrome. It's also applied for minor concerns like bruises, scrapes, toothaches, headaches, nausea, coughs, and colds. However, it's important to understand that homeopathy should not be used for life-threatening illnesses such as asthma, cancer, heart disease, or emergencies (4,5).

Are There Any Risks To Know About With Homeopathy?

Homeopathic remedies, due to their dilution, usually do not have side effects. Some people, however, report a temporary worsening of symptoms when starting a homeopathic treatment, interpreted by homeopaths as the body's attempt to restore health. These temporary aggravations can be potentially harmful to individuals with serious illnesses. Therefore, if you have a serious physical or mental illness, you should only use homeopathy under the guidance of a trained practitioner and inform all your healthcare providers about any homeopathic medicines you're taking. While homeopathic medicines sufficiently diluted are generally not known to interfere with conventional drugs, it's always prudent to consult your doctor if you're considering using homeopathic remedies and are currently on prescription medications (4).

While homeopathy is generally considered safe due to the high dilution of its remedies, there can be potential side effects and risks to be aware of. One notable concern is that some products sold or labeled as homeopathic might not be properly diluted; these can contain substantial amounts of active ingredients, which may cause drug interactions or side effects.

A systematic review conducted in 2012 concluded that using certain homeopathic products that contain heavy metals like mercury or iron (not highly diluted) or replacing an effective conventional treatment with an ineffective homeopathic one could cause adverse effects, some of which could be serious. Liquid homeopathic products may also contain alcohol, and the levels allowed in these products can be higher than in conventional drugs (9).

The concept known as “homeopathic aggravation” is a temporary worsening of symptoms after taking a homeopathic prescription and is often expected by homeopathic practitioners. Although not much evidence of this reaction is found in clinical studies, and research on this topic is limited, any changes in symptoms should be discussed with a healthcare provider (9).

Additionally, there have been warnings from regulatory bodies regarding certain homeopathic products. For example, in 2017, consumers were alerted that some homeopathic teething tablets contained excessive amounts of the toxic substance belladonna. In 2015, a warning was issued advising against reliance on over-the-counter asthma products labeled as homeopathic because they had not been evaluated for safety and effectiveness (9).

While the risk of serious injury or side effects from homeopathic remedies is considered small, it is recommended to consult with a healthcare professional before stopping any treatment prescribed by a doctor.
