Biologically
Based Therapies Biologically based
therapies include substances found in nature, such as homeopathic
medications, herbs, dietary supplements, and vitamins. 1 The categories of homeopathy, herbs, and dietary
supplements often overlap. How
these products are regulated and manufactured and their indications for
use help define how they are classified.
According to the US Dietary Supplement Health and
Education Act passed by Congress in 1994, herbal products are regulated as
dietary supplements but when they are diluted and prepared as homeopathic
remedies, they become pharmaceutical products. 2 Homeopathy
The method of
action for homeopathy is not known.
It is particularly difficult to understand how it works since the
remedies are so diluted that the initial starting substance can't even
be measured. 5 In general, it is
believed that homeopathy is safe if patients are under the
supervision of trained professionals.
Homeopathic remedies
are not known to interfere with other medications
the patient might be taking. Of
concern in pediatrics is that liquid homeopathic medicines can contain
higher levels of alcohol than conventional medications.4
Examples
of Use There are several randomized double-blinded control studies looking at the use of homeopathic medications in children. Oberbaum, et al. (2001),6 found that traumeel S, a homeopathic skin cream, reduced the severity and length of pain and inflammation inside the mouth of pediatric bone marrow transplant patients. Pappano et al. (2007) 7, reported that although individualized homeopathic remedies statistically reduced the duration and frequency of stools in children with acute diarrhea this treatment is not widely used by pediatric providers because of concerns of efficacy, safety, and lack of experiential knowledge. The National Center for Homeopathy provides "A Parent's Guide to Children's Health Through Homeopathy" on their website, http://nationalcenterforhomeopathy.org/articles/child_resource_guide.pdf .8 This guide contains information for parents on the use of homeopathic treatment of otitis, fever, and flu in children. However, these treatments are not found to be supported by the results of a systematic review of randomized clinical trials done by Altunc, Pittler, & Ernst (2007).5 Herbs The use of herbal
dietary supplements is common in children and adolescents. Several national and international surveys estimate
their use at 28-40%. They are
used for a number of reasons including maintaining health, preventing
disease, and treating chronic or acute disease.
There also appears to be a strong cultural influence in their use. The use of herbal dietary supplements is often not disclosed
to health care providers. This
can be a particular problem in pediatrics since many of the treatments
have not been clinically tested for safety and efficacy in children and
they can often interact with other medications. 8,9
Examples of Use Herbs that have been commonly used in pediatrics include aloe (for burns) chamomile (primarily for stomach upset, colic, and diarrhea), Echinacea (for colds), garlic (for cardiovascular and infectious disease problems), ginger (for nausea and stomach upset), ginkgo (for ADHD), lavender (to promote relaxation), peppermint oil (for stomach upset), and St. John’s wort (for depression and nervous conditions). 10,11 Although there are a
number of articles, books, and internet resources available for health
care providers about the use of herbs for adults, resources about the use
of herbs for children are much more limited. In
addition, some published randomized control studies were flawed by a small
sample size, lack of product quality control, or only a single study was
done. Further well-designed pediatric studies are needed See the additional
Herbal Therapies resources page for more specific pediatric focused
information. Diet Supplements Diet supplements
include products such as vitamins, minerals, amino acids, herbs, and other
botanical products. Their
purpose is to supplement the diet to improve the structure and function of
the body. However, most of
these product benefits have not been backed by research or supported by
the FDA. In fact, product manufacturers must label their products with
a disclaimer that informs the user that beneficial claims have not been
evaluated by the FDA. 2
There have been great
variations in the quality and manufacturing practices of diet supplements.
In response to this, in 2007, the FDA finalized the Good
Manufacturing Practice Regulations. These
regulations help standardize product quality, manufacturing, packaging,
labeling, and storing processes. The
goal of the regulations is to provide safely manufactured and standardized
products for consumers. Examples
of Use Although
not always disclosed to their health care providers, many children and
adolescents use dietary supplements.
Vitamins and minerals (multivitamins and calcium) are the
supplements most commonly used. Although
these supplements may be beneficial for some children and adolescents, the
need for use by all has not been recommended. American Academy of Pediatrics Resources

another example of a dietary supplement that is used by children and
adolescents. Probiotics are
nonpathogenic microbes (generally lactic acid producing) that are taken
orally to improve or normalize the balance of GI microflora.
Probiotics are extremely safe for use by healthy children and may
be so even in immunocompromised or seriously ill children. 13 Examples of Use Research has
supported probiotic use in reducing the risk of antibiotic associated
diarrhea and reducing the duration of acute infectious diarrhea.14 Typically
probiotic treatment is initiated at the same time an antibiotic is being
given to prevent antibiotic associated diarrhea.
The typical duration of therapy varies from 1 to 4 weeks depending
upon the resolution of symptoms.13 Although the safest
forms of probiotic bacteria are found in fermented foods such as yogurt,
supplemental forms usually provide higher more effective amounts of
bacteria. 13
The exact composition of the most effective probiotic for children
has not been determined but it has been shown that an adequate dose of any
probiotic is key to its’ effectiveness.
Doses in the range of 5 to 10 billion colony forming units (cfu)
per day or higher are considered appropriate for most children. 14
