Eczema is a common inflammatory
condition of the skin. Many skin diseases cause symptoms similar to those
of eczema, so it is important to have the disease properly diagnosed
before it is treated.
What are the symptoms of eczema? Eczema is
characterized by scaling, thickened patches of skin that can become red
and fissured. It may also appear as tiny blisters (called vesicles) that
rupture, weep, and crust over. The most troublesome and prevalent symptom
of eczema is itching, which may be constant.
Conventional treatment
options: White petrolatum, hydrogenated vegetable oil, or other emollients
are often recommended to hydrate the excessively dry skin of eczema. The
mainstay conventional treatment for eczema is topical corticosteroid cream
or ointment (triamcinolone [e.g., Aristocortr, Triacetr, Kenalogr],
mometasone [Eloconr], cortisone [e.g., Cortoner] and others). Avoidance of
known allergens is also recommended.
Dietary changes that may be
helpful: Eczema can be triggered by allergies.1 2 Most children with
eczema have food allergies, according to data from double-blind research.3
A doctor should be consulted to determine whether allergies are a factor.
Once the trigger for the allergy has been identified, avoidance of the
allergen can lead to significant improvement.4 However, "classical" food
allergens (e.g., cows'milk, egg, wheat, soy, and nuts) are often not the
cause of eczema in adults. A variety of substances have been shown, in a
controlled trial, to trigger eczema reactions in susceptible individuals;
avoidance of these substances has similarly been shown to improve the
eczema. Triggers included food additives, histamine, salicylates,
benzoates, and other compounds (such as aromatic compounds) found in
fruits, vegetables, and spices.5 These reactions do not represent true
food allergies but are instead a type of food sensitivity reaction. The
authors of this study did not identify which substances are the most
common triggers.
It has been reported that when heavy coffee
drinkers with eczema avoided coffee, eczema symptoms improved.6 In this
study, the reaction was to coffee, not caffeine, indicating that some
people with eczema may be allergic to coffee. People with eczema who are
using a hypoallergenic diet to investigate food allergies should avoid
coffee as part of this trial.
Nutritional supplements that may be
helpful: Researchers have reported that people with eczema do not have the
normal ability to process fatty acids, which can result in a deficiency of
gamma-linolenic acid (GLA).7 GLA is found in evening primrose oil (EPO),
borage oil, and black currant seed oil. Some,8 9 10 but not all,11 12 13
14 double-blind trials have shown that EPO is useful in the treatment of
eczema. An analysis of nine trials reported that the effects for reduced
itching were most striking.15 Much of the research uses 12 pills per day;
each pill contains 500 mg of EPO, of which 45 mg is GLA. Smaller amounts
have been shown to lack efficacy.16
Supplementation with borage
oil, another source of GLA, has led to reductions in skin inflammation,
dryness, scaliness, and itch in eczema patients in some,17 but not all,
preliminary18 or double-blind trials.19
Many years ago, use of
large amounts of vegetable oil (containing precursors to GLA) was reported
to help treat people with eczema,20 21 but these studies were not
controlled and do not meet modern standards of research.
Ten grams
of fish oil providing 1.8 grams of EPA (eicosapentaenoic acid) per day
were given to a group of eczema sufferers in a double-blind trial. After
12 weeks, those using the fish oil experienced significant improvement.22
23 According to the researchers, fish oil may be effective because it
reduces levels of leukotriene B4, a substance that has been linked to
eczema.24 The eczema-relieving effects of fish oil may require taking ten
pills per day for at least 12 weeks. Smaller amounts of fish oil have been
shown to lack efficacy.25
One trial using vegetable oil as the
placebo reported that fish oil was barely more effective than the placebo
(30% vs. 24% improvement).26 As vegetable oil had previously been reported
to have potential therapeutic activity, the apparent negative outcome of
this trial should not dissuade people with eczema from considering fish
oil.
Although supplementation with 400 IU of vitamin E per day has
been reported in anecdotal accounts to alleviate eczema,27 research has
not supported this effect.28 Moreover, rare cases of topical vitamin E
potentially causing eczema have appeared.29 People with eczema should not
expect vitamin E to be helpful with their condition.
A double-blind
trial reported that use of a hypoallergenic infant formula plus probiotics
(500 million organisms of Lactobacillus GG bacteria per gram of formula,
taken for one month) initially led to improvement in eczema symptoms in
infants with suspected allergy to cows'milk.30 However, by the end of two
months, both the group receiving Lactobacillus GG and the placebo group
had improved approximately the same amount. In the same report, a
preliminary trial giving 20 billion Lactobacilli twice per day to
breast-feeding mothers led to significant improvement of their allergic
infants' eczema after one month. Probiotics may reduce allergic reactions
by improving digestion, by helping the intestinal tract control the
absorption of food allergens, and/or by changing immune system
responses.
In 1989, Medical World News reported that researchers
from the University of Texas found that vitamin C, at 50-75 mg per 2.2
pounds of body weight, reduced symptoms of eczema in a double-blind
trial.31 In theory, vitamin C might be beneficial in treating eczema by
affecting the immune system, but further research has yet to investigate
any role for this vitamin in people with eczema.

effects or interactions? Refer to the individual supplement for
information about any side effects or interactions.
Herbs that may
be helpful: The table below summarizes the three categories of herbs used
for people with eczema: anti-inflammatories and herbs that affect the
immune system (immunomodulators), astringents (herbs that bind fluids and
exudates), and herbs that affect the liver (also called alteratives).
Alterative herbs are poorly researched. Astringents are only helpful if
applied topically when weeping eczema is present; they will not help
people with dry eczema.
Mechanism of Action -
Examples
Anti-inflammatory and/or immunomodulator - Allium cepa,
Calendula, chamomile, chickweed, licorice, onion, Zemaphyter Chinese
herbal formula
Astringent (helps dry up weeping lesions) - Oak,
witch hazel (also anti-inflammatory)
Alterative (liver-supportive)
- Burdock, red clover, sarsaparilla, wild oats
Zemaphyte, a
traditional Chinese herbal preparation that includes licorice as well as
nine other herbs, has been successful in treating childhood and adult
eczema in double-blind trials.32 33 34 One or two packets of the
combination is mixed in hot water and taken once per day. Because one
study included the same amount of licorice in both the placebo and the
active medicine, it is unlikely that licorice is the main active component
of Zemaphyte.35
Several Chinese herbal creams for eczema have been
found to be adulterated with steroids. The authors of one study found that
8 of 11 Chinese herbal creams purchased without prescription in England
contained a powerful steroid drug used to treat inflammatory skin
conditions.36
A cream prepared with witch hazel and
phosphatidylcholine has been reported to be as effective as 1%
hydrocortisone in the topical management of eczema, according to one
double-blind trial.37
Topical applications of chamomile have been
shown to be moderately effective in the treatment of eczema.38 39 One
trial found it to be about 60% as effective as 0.25% hydrocortisone
cream.40
Onion injections into the skin and topical onion
applications have been shown to inhibit skin inflammation in people with
eczema, according to one double-blind trial.41 The quantity or form of
onion that might be most effective is unknown.
A Japanese topical
ointment called Shiunko has been reported to help improve symptoms of
eczema, according to preliminary research.42 The ointment contains sesame
oil and four herbs (Lithospermum radix, Angelica radix, Cera alba and
Adeps suillus) and was applied twice daily along with petrolatum and 3.5%
salt water for three weeks. Clinical improvement was seen in four of the
seven people using Shiunko.
Topical preparations containing
calendula, chickweed, or oak bark43 have been used traditionally to treat
people with eczema but none of these has been studied in scientific
research focusing on people with eczema.
Burdock, sarsaparilla, red
clover, and wild oats have been used historically to treat people with
eczema, but without scientific investigation.
Are there any side
effects or interactions? Refer to the individual herb for information
about any side effects or interactions.
Other integrative
approaches that may be helpful: Numerous trials have reported that
hypnosis improves eczema in children and adults.44 A preliminary trial
emphasizing relaxation, stress management, and direct suggestion in
hypnosis showed reduced itching, scratching, and sleep disturbance, as
well as reduced requirements for topical corticosteroids. All of the
patients studied had been resistant to conventional
treatment.45
