Homopathy
& Psoriasis
Psoriasis is still considered to be a
chronic and incurable skin condition and conventional medical treatment relies on a
combination of controlled ultraviolet light exposure (sometimes after ingestion of
sensitising chemicals called psoralens), lotions containing tar derivatives, and steroid
creams to alleviate the condition. Oral steroids and even cytotoxic drugs are also
sometimes used in severe cases.
But long-term use of these treatments can produce serious
side effects ranging from advanced osteoporosis, high blood pressure ( from
corticosteroids) to liver and kidney abnormalities (methotrexate) and hair loss, severe
gingivitis necessitating tooth extraction and fetal malformation (retinoids).
It is therefore encouraging to find that German researchers
have recently demonstrated that a new homopathic topical ointment can effectively
alleviate the symptoms of psoriasis in over eighty per cent of psoriasis sufferers.
Mahonia aquifolium ointment is listed as an
homopathic preparation in the German Homopathic Pharmacopoeia. In an open,
prospective multi centre trial in 89 dermatological practices throughout Germany, 433
patients with subacute and chronic forms of psoriasis were treated with Mahonia aquifolium
ointment for up to a period of one year. 375 of the patients continued with the treatment
for a year as planned or dropped out of the study early because they had experienced a
complete clearance of their skin.
According to an overall evaluation by the participating
dermatologists, symptoms improved or disappeared in 81.1% of the patients which was
confirmed by the patients own subjective evaluation of the efficacy of the
treatment.
The tolerability of Mahonia aquifolium ointment was
evaluated as good or very good by 82.4% of patients. The treatment was also seen to
produce a significant improvement in the quality of life, which was used as a subjective
parameter throughout the study.
A detailed appraisal of the results found that while, at
the start of the study, 30.1% of patients had significant or severe symptoms, after the
first 12 weeks of treatment, only 5.6% of the patients fell within this category.
The researchers concluded that Mahonia aquifolium ointment
is a well-tolerated topical preparation which offers a valuable alternative to
conventional treatments and they went on to recommend that this new homopathic
ointment should find a place in the available treatments for psoriasis sufferers.

Psychotherapy
& Psoriasis
It has been widely acknowledged for some
time that psoriasis is a stress-related skin disorder, and it is therefore surprising that
stress management and relaxation techniques (e.g. meditation, biofeedback,
visualisation,etc) are not generally utilised in conventional treatment which largely
focusses on topical applications. However, researchers in Denmark recently investigated
the role of psychotherapies (including stress management, guided imagery and relaxation)
in helping psoriasis sufferers.
Fifty one patients with psoriasis vulgaris were randomly
assigned to either a treatment group involving seven individual psychotherapy sessions
over a period of 12 weeks, or to a control group. The researchers took a number of
measures to determine the changes in the patients conditions including Psoriasis
Severity Index (PASI), Total Sign Score (TSS) and Laser Doppler Skin Blood Flow
(LDSBF) of
a selected area of affected skin. Scores were taken at the beginning of the study and then
again at 4, 8 and 12 weeks.
The results revealed that improvements in three measures
were found in the treatment group which were not evidenced in the control group. Whilst
these improvements were generally considered to be modest, they were found to be
statistically significant. The researchers concluded that their preliminary study suggests
that psychological interventions have beneficial effects on psoriasis sufferers and should
be considered as a valuable adjunct to existing treatments.
As a pilot study, this research paper confirms that
psychotherapies may play an important role in the treatment of psoriasis and one cannot
help wondering why dermatologists have ignored the psychological approach for so
long.
Hopefully, this study will inspire further investigations into specific treatment
modalities so that they can assess which forms of psychotherapy may be more or less
appropriate for psoriasis sufferers.

Mahonia Aquifolium
& Psoriasis
Following a report in the issue of
ALTERNATIVES in health of the use of mahonia aquifolium ointment for psoriasis, a
trawl of the international medical databases reveals more evidence of this remarkable
herbal extract and more precisely, why and how it helps patients with psoriasis and other
skin complaints.
What is Mahonia aquifolium?: -
Mahonia aquifolium is
widespread in the forests of North America, and is also known as the cultivated plant
Mahonia. It is commonly found in gardens and parks growing as high as 1 - 2
metres with ever-green, leathery pinnate leaves, with a very shiny upper surface and a
thorny toothed edge.
Its yellow buds develop into blue , frost-covered
berries which contain a dark-red juice and contain 2-5 shiny seeds. The berries are edible
and are used to make wine and brandy. The bark of roots and stems contain alkaloids which
have a number of therapeutic properties.
In North American medicine, Mahonia aquifolium has been
traditionally used to treat fever, diarrhoea, dyspepsia, gout, rheumatic ailments, kidney
and liver diseases, but most prominenetly for skin complaints. However, only in the last
five years have scientists discovered how and why this herbal extract is so beneficial for
psoriasis sufferers.
Mahonia aquifolium applied topically and taken internally
as a remedy for psoriasis. The very first clinical study involving Mahonia aquifolium as a
treatment for psoriasis occurred in 1992.
In a multi-centred, randomised, controlled study, 93
patients suffering from mild to moderately severe psoriasis received treatment by either
topical application of Mahonia aquifolium ointment or internal ingestion of Mahonia
aquifolium extract. At the end of the treatment, significant improvement had occurred in
more than 70 per cent of patients in both groups.

Mahonia aquifolium - A new type of topical treatment for
psoriasis: - The first study to attract media attention about Mahonia aquifolium was an
open, prospective multicentre trial in 89 dermatological practices in Germany, where 433
patients with subacute and chronic forms of psoriasis were treated with Mahonia aquifolium
ointment.
Of the 433 patients who entered into the study, 375 were
treated over the planned period of 12 weeks, or dropped out of the study early because of
total clearing of the skin, A modified PASI score fell significantly from 5.5 plus or
minus 4.0 to 2.3 plus or minus 2.6.
According to an overall evaluation by dermatologists,
symptoms improved or disappeared in 81.1% of patients; and according to a subjective
evaluation by the patients, 79.7% improved or healed completely. The tolerability of
Mahonia aquifolium ointment was evaluated as good or very good by 82.4% of patients.
There was a significant improvement in the quality of life,
which was used as a subjective parameter throughout the study. While 30.1% of patients had
significant or severe symptoms at the start, this was the case for only 5.6% after 12
weeks. M. aquifolium ointment is thus a well-tolerated preparation which should find a
place in the treatment of psoriasis.

Mahonia aquifolium in patients with psoriasis vulgaris - an
intraindividual study: - A randomised, placebo-controlled clinical trial was established
to investigate the efficacy and safety of Mahonia aquifolium bark extract in psoriasis
patients. From autumn 1990 to Spring 1992, 82 patients, of all severity
gradings, were
recruited from 22 family physicians. The patients were instructed to apply two types of
ointment (verum/placebo), one to the left side of their body and the other to the right
side. After an average treatment period of four weeks, the treatment success was assessed
on a three-level ordinal rating scale. The patients reported significant
improvements. Adverse reactions (eg. itching, burning sensations) occurred in four of the
patients. The researchers stated that "Mahonia seems to alleviate symptoms especially
in moderately severe cases", and concluded that "Mahonia aquifolium bark extract
as a potent and safe therapy of moderately severe cases of psoriasis
vulgaris.

The antipsoriatic Mahonia aquifolium and its active
constituents: - The extract of the bark of Mahonia aquifolium is an inhibitor of
keratinocyte growth (abnormal skin cell growth) with an IC50 of 35 microM. Of its main
alkaloids tested, berberine inhibited cell growth to the same extent as did the Mahonia
extract, while the benzylisoquinoline alkaloids berbamine and oxyacanthine were more
potent inhibitors by a factor of three.

Products of lipoxygenase metabolism are known to play a
role in the pathogenesis of psoriasis. Six bisbenzylisoquinoline (BBIQ) alkaloids -
oxyacanthine, armoline, baluchistine, berbamine, obamegine, aquifoline - isolated from
Mahonia aquifolium, were tested for lipoxygenase inhibition.
Berbamine and oxyacanthine were the most potent
lipoxygenase inhibitors, whereas aromoline and baluchistine exhibited only very low
potencies. Oxyacanthine and berbamine were also among the most active compounds to inhibit
lipid peroxidation. Between the results of lipoxygenase inhibition and the lipid
peroxidation a linear correlation was found.
The data suggests that the mechanism of lipoxygenase
inhibition by these alkaloids, inhibition of lipid peroxide substrate accumulation, either
by direct reaction with peroxide or by scavenging or lipid-derived radicals, may play a
role in alleviating the symptoms of psoriasis. Inhibition of lipoxygenase by these
compounds may explain the therapeutic effect of Mahonia aquifolium extract in treatment of
psoriasis.

Antifungal screening of medicinal plants of British
Columbian native peoples: - One hundred methanolic plant extracts were screened for
antifungal activity against 9 fungal species. Eighty-one were found to have some
antifungal activity and 30 extracts showed activity against 4 or more of the fungi
assayed. The extracts with the greatest fungal inhibition were prepared from Mahonia
aquifolium roots, Alnus rubra catkins, Artemisia ludoviciana aerial parts, Artemisia
tridentata aerial parts, Geum macrophyllum roots, and Moneses uniflora aerial parts.

The antipsoriatic Mahonia aquifolium and its active
constituents: -The effects of the extract of the bark of Mahonia aquifolium and its main
constituents (berberine, berbamine, oxyacanthine) on 5-lipoxygenase, lipid peroxidation in
phospholipid liposomes induced by 2,2'-azo-(bis-2-amidinopropane), deoxyribose
degradation, and their reactivities against the free radical 2,2-diphenyl-1-picrylhydrazyl
have been studied. The extract of Mahonia aquifolium inhibits 5-LO with an IC50 value of
50 microM, whereas no appreciable effects were observed by its constituent alkaloids.
Pro-oxidant effects by Mahonia aquifolium or its
constituents can be excluded, since deoxyribose degradation was not influenced as
determined by the release of malondialdehyde. The most prominent feature of Mahonia
aquifolium is its efficacy in inhibition of lipid peroxidation (IC50 = 5 microM) which was
not mediated by the alkaloids berberine, berbamine, and oxyacanthine.

Sarsaparilla
& Psoriasis
Sarsaparilla, the root of the Smilax, a trailing vine or shrub
native to South America, has been shown to be extremely beneficial for psoriasis
sufferers. In one study, a group of 75 sufferers were given sarsaparilla tablets and 62%
reported noticeable improvements (1).
Water extract of Sarsaparilla was given in another study (2) to
psoriasis sufferers which led to decreased desquamation (scaling) followed by
complete disappearance. 15gm of Sarsaparilla was put in 1000mg of tepid water and left
overnight. The following day the mixture was boiled for 20 minutes. Half was immediately
drunk while still hot, the remainder drunk during the day. One patient with a previously
stubborn case of psoriasis followed the treatment for 20 years without a single relapse at
any time (3).
