Compositions for and Method of Treatment for Psoriasis
Field of the Invention
This invention relates in general to a treatment for psoriasis and more
particularly to a medication for treating psoriasis having three different
formulations,
a system for using the medication, and a method of medical treatment.
1o Background of the Invention
Psoriasis is a skin disorder that includes the presence of small elevations of
the
skin that may be characterized as elevated red lesions, plaques or pustules on
the skin
which eventually result in silvery scales. These silvery scales and plaque are
the
result of accelerated epidermal proliferation and the metabolic activity and
proliferation of capillaries in the dermal region and the invasion of the
dermis and
epidermis by inflammatory cells. More specifically, the capillaries in the
dermal
region become tortuous and dilated as well as suffering an inflammatory
reaction
causing the skin to redden.
The exact mechanism which triggers the abnormal cell proliferation is not
known, though it is believed there may be biochemical stimuli and
environmental
factors. The severity and course of psoriasis can vary greatly depending on
the
individual, but in general this chronic skin condition recurs throughout the
life of the
individual with varying intervals of one month to many years.
Over the years a wide variety of methods of treatment for psoriasis, both
topical and systemic, which inhibit the cell division have been developed. In
general,
these methods have met with limited short term success and are not very well
understood. As the disease requires treating the individual intermittently
during their
lifetime, treatment risk increases with treatment length since common
medicaments
evidence cumulative long term side effects.

Historically, psoriasis has been treated topically with coal tar derivatives
as
well as salicylic acid with limited success. Corticosteroids and other similar
drugs
have been found effective for serious cases of psoriasis. Unfortunately many
of these
drugs produce serious side effects, and in some cases once the drugs are
discontinued,
the psoriasis recurs with marked exacerbation. Other forms of treatment
include folic
acid antagonists, ionizing radiation therapy, a variety of combinations of
ointments
and polyethylene films, sunlight and ultraviolet baths.
Prior art psoriasis medications and methods of medical treatment have been
1o devised to address the aforenoted problems. For example, United States
Patent No.
5,425,954 issued on June 20, 1995 to Thompson et al. and provides for a
composition
for topical application to the skin comprising a mixture of Panthenol (BS),
Cod Liver
Oil, Alpha Tocopherol Acetate, Arginine, Isoleucine, Leucine, Methionine,
Phenylalanine, Threonine, and Valine in admixture with a suitable Garner.
United States Patent No. 5,165,932 issued on November 24, 1992 to Horvath
and relates to therapeutical compositions on medical herb basis for the
treatment of
psoriasis and the preparation of the same. The medical herbs used in the
invention are
Album sativum/garlic/, Urtica dioicalcommon nettle/, Chelidonium
majus/milkweed/,
2o Veronica officinalis/veronical, Calendula officinalis/calendula or
marigold/, Achillea
herbalmillefolium/yarrow/ and Fumaria officinalis/fumitory, earth-gall.
United States Patent No. 4,981,681 issued on January 1, 1991 to Tosti and
relates to a method for treating psoriasis and more particularly it relates to
a method
of treating psoriasis by systematic and periodic application of several
selected
ingredients including the active ingredient Salicylic Acid.
United States Patent No. 5,886,038 issued on March 23, 1999 to Glenn et al.
and relates to a pharmaceutical composition for use in the treatment of
psoriasis,
3o having isopropyl myristate as its only active ingredient.
CA 02305062 2000-04-12

United States Patent No. 5,990,100 issued on November 23, 1999 to
Rosenbert et al. and this patent relates to pharmaceutical compositions and
methods
for use in the treatment of psoriasis, having isopropyl myristate as a first
active
ingredient and a different anti-psoriatic agent as a second active ingredient;
preferably
they are combined in the same pharmaceutical composition.
Thus a composition, system and method of treatment for psoriasis which
allows for the successful treatment by reducing the frequency of the
recurrence of the
psoriasis is desirable.

Detailed Description of the Preferred Embodiment
1o The present invention relates to novel compositions and method of applying
these compositions, which comprise of a selected mixture of herbal extracts
and coal
tar, which have the ability to reduce inflammation associated with psoriasis
thereby
encouraging healthy skin growth. The topical application of these novel
compositions
acts to treat skin, which has psoriasis. Topical application means the
introduction of
the novel compositions to the skin via a suitable base or vehicle.
Conventional
understanding of topical applications include but are not limited to creams,
ointments,
lotions, gels, pastes, powders, sprays, washes and the like.
The first novel composition of the present invention is comprised of the
2o following essential herbal extracts and coal tar which have been formulated
into a
body wash composition, which has demonstrated in a reduction of inflammation
associated with skin having psoriasis. Each of the components herein described
is
believed to contribute to the natural healing process of the psoriasis
afflicted area
although the exact mechanisms are not completely understood. The essential
components of the novel body wash composition are: coal tar solution, mallow
extract, rosemary oil, eucalyptus oil, a blend of proteins and wheat germ oil.
The
essential components are included in a suitable carrier for a body wash. More
particularly a preferred composition of the body wash can contain a mixture of
