Homeopathy is a non-toxic system of medicine used to treat illness and relieve discomfort
of a wide variety of health conditions. It is practiced by licensed physicians and other
qualified prescribers in many regions of the world, including Europe, Asia, the U.K., and the
U.S. Information on the use of several hundred remedies has been collected for nearly two
centuries by homeopathic practitioners, through research studies known as
“provings,” as well as documented clinical cases and recent scientific trials.

The Law of Similars and Potentization
Two important ideas on which the science of homeopathy is based are the Law of Similars and
potentization. Simply expressed, the Law of Similars states that since exposure to a substance
can cause specific symptoms in a healthy person, that substance—when correctly prepared
as a homeopathic remedy—can stimulate the body’s curative powers to overcome
similar symptoms during illness.
For example: A person who chops an onion can develop watery eyes, a runny nose, sneezing,
coughing, and throat irritation from exposure to the onion’s active substances. The
homeopathic remedy, Allium cepa, made of potentized red onion, can help the body
overcome a cold or allergy attack in which the person has similar symptoms (watery eyes, runny
nose, sneezing, coughing, or throat irritation.) The actual symptoms of the illness were not
caused by exposure to an onion, but the remedy made from the onion can help the body overcome
them, because the symptoms are similar.
Potentization is a process that involves a series of precise dilutions and succussions
(succussion is a vigorous shaking action). A substance has to undergo this process to be
useful as a homeopathic remedy. Potentization is very important, because the repeated process
of dilution and succussion brings about an energetic change that gives the substance a deeper
curative effect. Repeated dilution removes all chance of chemical toxicity, allowing the
homeopathic use of many substances that would otherwise not be safe to take as medicine.
The safety and non-toxicity of homeopathic remedies is reassuring; however, they still must
be chosen carefully on the basis of specific information—and used correctly—or
they may affect the symptoms only superficially, or have no effect at all. Homeopathic
remedies are not selected simply to treat an isolated symptom or a named disease. To work
correctly, they must be chosen to match the way an individual’s system expresses its
unique response to the current stress and illness. Even within the same diagnosis, different
people respond to different remedies.
How to Use Homeopathic Remedies
Self-care with homeopathy for moderate, short-term illnesses and injuries can be rewarding. A
correctly-chosen remedy can work gently and efficiently to relieve discomfort and help the
body heal itself without toxicity or side-effects. If an illness or condition is chronic or
serious, it is best to consult an experienced prescriber for a remedy that more deeply suits
the person’s needs. (See “Constitutional Remedies,” below.)
Observe the person, taking special note of the strongest and most unusual symptoms, as well
as the way the individual responds to the stress of illness, such as things that relieve or
aggravate the symptoms (motion, temperature, light, noise) or the person’s emotional and
Choose the remedy whose description most closely matches the symptoms the person is
expressing. When a remedy’s pattern of action is similar to the person’s response
to the stress or illness, it can help the natural defenses more efficiently overcome the
problems and return the person to a better state of health.
Take one dose of the selected remedy, then wait for a response to show. If relief of
important symptoms is noted—or if the person starts to improve in general—the
remedy is acting. Continue to wait and let it do its work. Do not give another dose unless
improvement stops. (Unnecessary repetitions can interfere with or slow down a remedy’s
Further doses of the remedy should be given according to how the person is responding, not
on a pre-set schedule. Intense or painful situations may require more frequent repetitions.
For instance, in severe discomfort (as with a burn or throbbing headache) a dose may be needed
every few minutes to an hour. In moderate conditions, such as flu or indigestion, a dose once
every few hours may be indicated. In many situations, one dose of a correctly-chosen remedy
will be enough to stimulate the body to heal itself.
If no response is evident after a reasonable amount of waiting, give another dose and wait
again. If no response is seen after several repetitions, review the important symptoms and
choose another closely-indicated remedy.
Lower potencies (6X, 6C, 12X, 12C, 30X, 30C) are the most appropriate for non-professional
self-care situations. A 30 will often act more quickly and deeply than a 6 and need fewer
repetitions—but, the higher the potency, the more precise the remedy choice must be to
bring results. High potencies (past 30C) should only be used by those with formal homeopathic
training, as a more developed knowledge of the remedies is needed to make an accurate
prescription and to monitor results. (See also
Understanding Homeopathic Potencies.)
Using Homeopathy with Professional Guidance
Homeopathic remedies can also be helpful in complex or even serious conditions—although
self-prescribing is not appropriate in such cases. To correctly select the remedy and monitor
the healing process, an experienced physician who is trained in homeopathy should be involved,
for the following reasons:
- Medical knowledge is needed to assess complex or serious conditions. Professional
diagnostic tests may be necessary, as well.
- Using a remedy that covers isolated symptoms superficially, but does not fit the person on
deeper levels, may change or suppress the symptoms, yet not be deeply curative.
- Even with a correctly-chosen remedy, a temporary aggravation of symptoms may occur as part
of the healing process. Training and experience are required to distinguish a helpful
aggravation from an intensification of symptoms that occurs because a remedy has not acted and
the illness is progressing.
- An inexperienced or impatient person might be tempted to repeat the remedy unnecessarily,
or change to other remedies at times when waiting is appropriate.
If an illness or condition is chronic or deep-seated, it is best to consult an experienced
homeopathic practitioner, for a “constitutional” remedy that fits the
characteristic symptoms of the case and considers the person’s physical condition and
individual nature in a more comprehensive way. At at typical first visit, a homeopath
interviews a patient for at least an hour—to take a careful history and elicit
information about many aspects of the person’s state of health—before choosing a
How Does Homeopathy Work?
Within the limitations of available scientific funding, interesting research is being
undertaken to understand how and why such highly-diluted remedies have profound and curative
effects. Formal studies published in current medical journals show that homeopathic remedies,
when used correctly, are significantly more effective than placebo. Researchers theorize that,
during potentization, an energetic change occurs in the remedy substance and its medium of
dilution (usually water), enabling them to stimulate a person’s system to deal with
stress and illness more efficiently. Homeopathic remedies do not have chemical action in the
body, and thus work differently than nutrients or drugs—which has made it difficult for
some researchers accustomed to assessing drugs to adequately consider them. Since the body is
clearly affected by many forces that have no chemical content (electricity, radiation, thermal
energy, etc.), it is reasonable to think that research designed to observe non-chemical
effects will yield more useful information.
