If you’ve ever picked up a homeopathic product and wondered what exactly homeopathic means, you’re not alone. With its own terminology, potencies, and approach to choosing a remedy, homeopathy may feel a little unfamiliar at first. But the basic ideas behind homeopathy are actually fairly simple—and they have been around for more than 200 years.
A Look Back at Homeopathy
Homeopathy as we know it today was developed in Germany in the late 18th century by physician Samuel Hahnemann, although some of the ideas behind it have much earlier roots. Hahnemann had a background in medicine, chemistry, and toxicology and experimented with substances on himself and other healthy individuals to better understand the symptoms they produced.1
His observations eventually became the foundation of a new system of medicine, which he formally described in Organon of the Art of Healing in 1810. Homeopathy spread quickly, reaching the United States by the early 1800s, with the first physician practicing homeopathy opening an office in 1825.1
More than two centuries later, homeopathy continues to be used around the world, with the preparation and manufacturing of homeopathic medicines becoming increasingly standardized.1
The Three Basic Principles
Homeopathy is rooted in three basic principles that help explain its unique approach: like cures like, totality of symptoms, and minimum dose.2
- Like Cures Like
This principle is based on the idea that a substance capable of causing certain symptoms in a healthy person may be used homeopathically for someone experiencing similar symptoms.2,3
For example, cutting an onion can leave you with burning, watery eyes and a runny nose. Allium cepa, a homeopathic remedy made from onion, is used to address similar symptoms.2 - Totality of Symptoms
Homeopathy looks at the overall pattern of symptoms—including how they feel, when they started, and what seems to make them better or worse.1,2 That means two people with a similar complaint may not necessarily use the same homeopathic remedy.
For example, two people with an upset stomach may experience it very differently. One person may feel chilly and not be thirsty, while another feels hot and craves water. These differences can help determine which homeopathic remedy is the best match.2 - Minimum Dose
The third principle is just what it sounds like: using the minimum amount necessary. Homeopathic medicines are prepared through a process of successive dilution, and many finished homeopathic remedies are highly dilute.2,3
Within traditional homeopathic practice, both the potency of the remedy and how frequently it is taken are considered when determining dosing.2
Getting to Know Homeopathic Ingredients
Starting substances can come from some surprisingly familiar sources. Plants such as red onion, arnica, poison ivy, belladonna, and stinging nettle have all been used, along with substances derived from minerals and animals.3
You’ll also find homeopathic remedies in familiar forms. While the small pellets that dissolve under the tongue may be the most recognizable, homeopathic products can also come as tablets, drops, creams, gels, and ointments.3
One Size Doesn’t Necessarily Fit All
This is where homeopathy can start to feel confusing. How strong is a particular potency? How often should you take it? And what do all those numbers and letters mean?
A helpful way to start thinking about potency and frequency is to imagine homeopathic remedies as music. Think of the potency as the volume and the frequency of dosing as the tempo. A low volume played at a slow tempo is gentle. Turn up the volume while keeping the tempo slow, and the music becomes more intense. Combine a louder volume with a faster beat, and the overall effect becomes much stronger.2
A higher potency or more frequent dosing each changes the approach, while combining higher potency with frequent dosing represents a more aggressive dosing strategy.2
For finished homeopathic products, the labeled directions provide the appropriate starting point, with a healthcare practitioner or homeopathic professional available when more individualized guidance is needed.
What Does the Research Say?
Homeopathy has been studied in clinical trials for decades, including through several large reviews and meta-analyses. Earlier reviews found overall positive trends in the clinical research, while also noting limitations in the quality and design of many of the available trials.4,5
More recently, a 2023 systematic review of meta-analyses of randomized, placebo-controlled trials reported statistically significant positive effects of homeopathy beyond placebo. The authors rated the evidence as high for individualized homeopathy and moderate for homeopathy overall and non-individualized homeopathy.6
Research continues, but together these findings provide support for continued scientific study of homeopathy and the different ways it is practiced.4-6
Homeopathy Around the World
Homeopathy may have originated more than two centuries ago, but its use today extends around the globe. Today, homeopathy is used by hundreds of millions of people around the world, with an estimated 250,000 physicians incorporating it into their practice.7,8 Homeopathy is also included within the national healthcare systems of several countries, including Brazil, Chile, India, Mexico, Pakistan, and Switzerland.8
Its continued use around the world, along with ongoing clinical research, has kept homeopathy part of the broader conversation surrounding complementary approaches to health.
The Bigger Picture
Homeopathy has its own terminology and traditions, so potencies, dosing, and ingredient names can take a little getting used to. But once you understand the three basic principles, it all starts to come together—and using homeopathic remedies can feel much simpler.
One of the defining aspects of traditional homeopathy is its emphasis on the whole picture rather than simply the name of a symptom or condition. As homeopathic author Dana Ullman describes it, “The science and art of homeopathy embody what many people envision as a 21st century medicine”—an approach centered on the individual and the full picture of their physical, emotional, and mental symptoms.9
More than 200 years after its beginnings, homeopathy continues to offer a unique, individualized approach to wellness. It can also be used alongside conventional healthcare as a complementary approach, allowing it to be part of a broader approach to supporting health and well-being.1
