DESCRIPTION
The artichoke bud / sarsaparilla extract is an entirely unique
complex of phytochemicals extracted from the bud of a hybrid
artichoke plant (Cynara floridanum) and the root of the sarsaparilla
plant (Smilax officinalis).
The proprietary extraction process uses a method in which
all plant materials are first combined, macerated, and put
into a distilled water / ethanol solvent. This allows the plant
materials to interact within the solvent resulting in an exceptional,
health-providing formulation of polyphenols and flavonoids.
FEATURES
· Artichoke bud / sarsaparilla extract has been created
by combining materials from two plants that have been historically
used as liver regenerative, detoxifying, and blood-purifying
agents.
· Artichoke bud / sarsaparilla extract is a complex
of liver-supportive, detoxifying phytonutrients that are extracted
using a proprietary, two-step method. It is unlike anything
in the marketplace today. Partial analysis has revealed a quite
extraordinary complex of flavonoids, including quercetin, rutin,
- (+) catechin, hesperidin, kaempferol, isorhamnetin, cynarin,
silymarin, caffeic acid, and chlorogenic acid. Phytosterols,
including ß-sitosterol, campesterol, and stigmasterol,
have also been detected.
The UMN Liver Support formula is a proprietary blend of Artichoke (Cynara Floridanum)/Sarsaparilla
(Smilax Aristolchiaefolia) contains the following naturally occurring bioflavonoids
(1-6) and chlorogenic acid:
1. silymarin
2. quercetin
3. catechin
4. hesperidin
5. rutin
6. cynarin and
7. chlorogenic acid
Bioflavonoids are a class of water-soluble plant pigments
(colors) that have anti-inflammatory, antihistaminic and antiviral
properties.
Naturally occurring bioflavonoids found in the Artichoke/Sarsaparilla
extract:
1. Silymarin
Numerous clinical studies have shown silymarin to be among the most powerful
natural agents available for the prevention and treatment of liver damage
caused by exposure to human-made chemicals, including alcohol-induced liver
degeneration and cirrhosis.

2. Quercetin
Quercetin, a bioflavonoid with antioxidant, anti-inflammatory and antihistamine
properties, has been shown useful in the treatment of inflammation, high cholesterol,
fatty-plaque formation in the arteries (atherosclerosis), diabetes and peptic
ulcer. In experimental studies, quercetin is found to be the most active flavonoid.
Quercetin inhibits several of the initial processes of inflammation,
thus it has an anti-inflammatory effect. Quercetin has demonstrated
its ability to inhibit the release of inflammatory chemicals
from mast cells sensitized by food allergies and to inhibit
irritability of the muscles of the intestines. This effect
makes it beneficial in relation to food allergies. It exerts
antioxidant and vitamin C-sparing activity. It also enhances
insulin secretion, protects pancreatic beta-cells from free
radical damage and inhibits platelet aggregation. Animal studies
demonstrate quercetin's anti-tumor activity against cancers,
including colon and rectal cancer.

3. Catechin
Catechin, another naturally occurring flavonoid, is similar
in effect to silymarin. A powerful antioxidant, catechin helps
prevent free-radical oxidative damage to cells. It also helps
in the treatment and prevention of alcohol and chemical-induced
liver disease or damage. Catechin is also valuable for its
ability to neutralize intestinal toxins and assist in the stabilization
of cell membranes.

4. Hesperidin
Hesperidin has been shown useful in clinical trials to have
significant analgesic (pain relieving) and anti-inflammatory
effects.

5. Rutin
Rutin has proven effective in numerous clinical studies to
inhibit oxidative (free-radical) damage in pathological human
red blood cells, and has the ability to reduce capillary fragility,
swelling and bruising. Effective in the treatment of venous
insufficiency (varicose veins, hemorrhoids, diabetic vascular
disease, and diabetic retinopathy), and for improving micro-vascular
blood flow (pain, tired legs, night cramps, and restless legs).

6. Cynarin
Cynarin is another active flavonoid in artichoke. Cynarin
is specifically helpful for detoxifying and supporting the
functions of the liver and gall bladder. Acting much like silymarin,
cynarin has shown significant protecting and regenerating effects
in the liver. It stimulates the clearance of bile from the
liver, preventing congestion in the liver and diminishing the
chances of liver damage.

SCIENTIFIC RESEARCH
Beneficial effects of flavonoids have been described for successfully
treating many health conditions, including cancer, viral infections,
diabetes, headaches, liver disease, ulcers, and allergies.
They can also bind to enzymes and DNA, chelate heavy metals,
and play a role in electron transport.
Phytosterols are plant fats. Plants do not contain cholesterol,
but phytosterols play a similar role in plants to that of cholesterol
in humans, primarily the forming of cell membrane structures,
sources of fuel for storage and transport, and protective surface
coatings. The most common plant sterols are ß-sitosterol,
campesterol, and stigmasterol. Recent studies have shown that
phytosterols have antihyperglycemic and insulin-releasing effects,
anti-inflammatory and antipyretic activities, and important
immune regulating and T-cell proliferative activities.
Extracts of the artichoke leaf stimulates bile production
in the liver and increased bile release from the gall bladder,
and thus has been effective in helping to eliminate toxic substances,
normalizing blood cholesterol levels, lowering blood lipids,
and providing liver protective qualities.
European physicians consider sarsaparilla root as an alterative
tonic, blood purifier, diuretic, and diaphoretic. With its
clinical uses as a blood purifier, it was registered as an
official herb in the U.S. Pharmacopoeia as a treatment for
syphilis from 1820 to 1910. Clinical observations in China
demonstrated that sarsaparilla is effective in about 90% of
acute cases and 50% of chronic cases of syphilis. In 1942 it
was shown to dramatically improve psoriasis, and in the 1950’s
the antibiotic properties of sarsaparilla were documented.
An herbal Saudi Arabian drug created from sarsaparilla has
been used for many years to treat rheumatism and various forms
of arthritis. Further studies showed that sarsaparilla inhibited
carrageenan-induced inflammation in rats. Recent research from
China has shown that an extract of sarsaparilla was able to
prevent immunological liver damage. And three studies performed
between 1994 and 1999, have shown that extracts of sarsaparilla
have snake venom inhibitory activity.

Report on ORACFL Values of the “UMN Liver Support”
Artichoke/Sarsaparilla Extract
Oxygen Radical Absorbance Capacity (ORAC) measures the ability
of the sample being analyzed to protect against attack by free
radicals, or to act as an antioxidant. Several methods have
recently been developed to measure the total antioxidant capacity
of biological samples, but the ORAC method is quite unique.
It measures the degree to which a sample inhibits the action
of an oxidizing agent and how long the inhibiting effect lasts.
It then integrates the two measurements into a single one.
This provides an accurate and reproducible measurement for
different types of antioxidants having different strengths.
The ORAC procedure provides a measure of total antioxidant capacity and will
measure the common nutrient antioxidants such as vitamin C, vitamin E, ß-carotene,
etc., plus a number of other naturally occurring phytochemicals, such as the
flavonoids and phenolic acids. The standard of comparison in this procedure
is Trolox (a water-soluble analog of vitamin E), which is defined as Trolox
Equivalents (TE).
The ORACFL analysis, which utilizes Fluorescein as the fluorescent probe, provides
a measure of the scavenging capacity of antioxidants against the peroxyl radical,
which is one of the most common reactive oxygen species (ROS) found in the
body.

There is much being studied and written in the scientific
world about antioxidants, phytochemicals, and nutraceuticals,
with a tremendous amount of research underway to determine
the role that specific antioxidants play in protecting the
body from harmful free radicals. Free radicals are atoms or
groups of atoms that can cause damage to cells, impair the
immune system, lead to infections and various degenerative
diseases such as heart disease and cancer. These free radicals
can be caused by exposure to radiation, toxic chemical exposure,
and various metabolic processes. Free radicals are kept in
check by the action of antioxidants. Antioxidants neutralize
free radicals.
Although antioxidants can be obtained from food sources, such as fresh fruits
and vegetables, it is difficult to obtain all that we need in our daily diets.
It is also known that it is best to take various types of antioxidants, not
just one, since they work synergistically to minimize free radical damage.
Reversing Liver Damage
By Charles L. Cochran, D.C.
Copyright Charles Cochran, 1999. All rights reserved.
Reprinted with permission of the author.
It’s a little difficult to get excited about the liver.
I don’t know if this results from our childhood when
mom tried to make us eat our liver (mine always tried to mask
the flavor with bacon and onions) or that it’s never
achieved the romance of such organs as the brain or heart.
Nevertheless, I know of no other organ that performs near as
many vital functions as this misaligned, often forgotten organ.
The liver is the largest internal organ in the human body
weighing 3-4 pounds. Unlike any other organ it has two sources
of blood supply: the hepatic artery carrying oxygenated blood
from the heart and the portal vein carrying food substances
from the intestines. Blood passes through the liver at a rate
of about 1.4 liters per minute, and at any instant contains
about 10% of the entire blood supply. The cells of the liver
closest to the entry of the portal vein and the hepatic artery
are called periportal hepatocytes.
Periportal hepatocytes have higher concentrations of oxygen
and nutrients than any other tissue in the body because the
liver is the first organ to receive nutrients absorbed by the
gastrointestinal tract. These same cells also have higher concentrations
of glutathione and transaminase enzymes, the enzymes used to
evaluate liver damage in standard blood tests. However, these
are the same cells that have the highest exposure to chemical
and environmental toxins.
The liver carries on over 500 functions essential for life.
These can be grouped into seven main categories:
1) storage of carbohydrates, vitamins, and minerals
2) metabolism of hormones, endogenous wastes, and foreign chemicals
3) synthesis of blood proteins
4) formation of urea
5) metabolism of fats, proteins, and carbohydrates
6) formation of bile and gamma globulin
7) assimilation and storage of fat-soluble vitamins
The liver is the main organ of biotransformation (the chemical
alteration that a substance goes through in the body). The
lungs and the kidneys are secondary organs of biotransformation,
having about one-third of the liver’s detoxification
capacity. The liver eliminates these compounds in one of three
ways: by secreting them into the bile ( a derivative of cholesterol
that aids in the emulsification of fats in the diet), by phagocytosis
( the offending compound is eaten by specialized liver cells
called Kupffer’s cells), or by chemically altering the
compound from non-polar molecules to polar molecules using
special enzymes making them water soluble and easier to eliminate.
These enzymes make up what is known as the cytochrome P-450
system. Cytochrome P-450 enzymes have been found in the intestines,
adrenal cortex, testes, spleen, heart, muscles, brain, and
skin. However, the highest concentrations are found in the
liver.
In this highly industrialized world that we live in, it’s
impossible to breathe and eat without taking in toxic chemicals.
The Environmental Protection Agency (EPA) estimates that 500,000
chemicals are in use today, and each year over 5,000 new chemicals
are added. I’ve read in several sources that up to 25%
of these chemicals that have been approved to be used in our
environment are cancer-causing or carcinogenic. And what is
even scarier is that there has been relatively few studies
of the detrimental effects that these chemical substances have
on our bodies when combined together. Overuse of alcohol, drugs
(including prescription), and tobacco, as well as, an improper
diet and overeating create an additional burden to the body’s
detoxification organs.
Liver Detoxification
Optimum health depends on a healthy liver. When the liver
is over-stressed, all other organs start to dysfunction as
well. The liver is constantly having to break down, not only
the environmental or external toxins, but also those produced
by the body during normal metabolic processes which we call
internal toxins. These internal toxins come from such compounds
as hormones, vitamins, cholesterol, inflammatory chemicals
and fatty acids that have served their function and been used
by the body and now need to be eliminated. In most illnesses,
health care providers should evaluate liver function. If it
can be improved, the entire body will usually benefit.
Fortunately, there has been extensive research using safe,
natural nutritional products that help in the phases of liver
detoxification. There are two phases in detoxification of the
body, Phase I and Phase II. Phase I refers to converting non-polar
molecules (like fats) into polar molecules (like water). Like
a magnet, polar molecules are shaped such that they have a
negative and positive pole. This conversion of non-polar to
polar molecules is accomplished by using very specific enzymes
and is necessary because most toxins are non-polar lipophilic
(fat soluble) molecules and are stored throughout the fatty
tissues in the body. Enzymes are complex proteins that are
capable of inducing chemical changes in other substances without
being changed themselves. They are like the key for your automobile.
Your key fits in the ignition of your car only and causes a
whole chain of events that lead to it moving down the road
without changing the shape or function of the key.
There are close to 100 enzymes that make up the cytochrome
P-450 system. Each enzyme works best in detoxifying specific
chemicals. However, there is some enzyme overlapping in case
one of the keys is damaged there is another one that can take
over and do the job. For example, much like the old worn out
key that won’t open the door anymore, DNA damage or genetic
defects can cause changes in these enzymes making them useless
to the body. These enzymatic reactions require the presence
of very specific nutrients. Nutrients required for Phase I
include beta-carotene, vitamin B1, vitamin C, and vitamin E.
The minerals necessary to support the liver during Phase I
detoxification are copper, iron, magnesium, manganese, molybdenum,
sulfur, and zinc. And other nutrients that can support this
phase are alpha-ketoglutaric acid, choline, essential fatty
acids, lecithin, and methionine.
Herbs used to support the liver in detoxifying the body include
milk thistle, golden seal, garlic, cayenne, licorice root,
yellow dock, and ginseng. Later in this article, I will introduce
you to a wonderful liver detoxification formula created from
extracts of a hybrid artichoke and sarsaparilla.
Phase I detoxification can be evaluated by the caffeine metabolism test. This
test is performed by ingesting caffeine and testing the saliva. Low caffeine
clearance indicates that cytochrome P-450 activity of the liver is abnormal
and these individuals would have difficulty eliminating toxins.
In Phase II detoxification, other chemical groups are added
to the compound, or conjugated, making it now completely water
soluble and available for excretion through the kidneys. Again,
there are nutrients that will support this second process,
including cysteine, garlic, D-glucarate, glycine, L-glutathione,
N-acetyl cysteine, and taurine. Vitamins essential for Phase
II detoxification are folic acid and vitamins B1, B2, B3, B5,
B6, and B12. The minerals necessary for this phase include
germanium, magnesium, manganese, molybdenum, sulfur, selenium,
and zinc.
Phase II detoxification can be evaluated by the ingestion
of acetaminophen (Tylenol) or aspirin and then checking for
the products of glutathione conjugation, sulfonation, glucuronidation,
and glycine conjugation.
Glutathione is composed of three peptides including glutamic
acid, cysteine, and glycine. It has the ability to take up
and give off hydrogen and consequently can protect the body
from hydrogen peroxide toxicity. Sulfonation describes a process
of adding inorganic sulfate to hydroxyl (-OH) groups for detoxification.
Glucuronidation is accomplished by the addition of a sugar
molecule using an important acid, glucuronic acid, which renders
certain toxic substances harmless. And glycine, a non-essential
amino acid, stimulates the production of glutathione and also
aids in the detoxification of benzoic acid and phenol.
A problem occurs when Phase I detoxification happens faster
than the Phase II detoxification. Phase I detoxification sometimes
creates compounds that are even more toxic than the original
chemical. And unless quickly removed by the Phase II detoxification,
these more active toxins produce problems throughout the body.
Studies have shown that individuals who have fast Phase I and
slow Phase II detoxification are more prone to developing cancer
and also suffer severe reactions to environmental toxins. Curcumin,
a flavonoid found in turmeric that gives it the yellow color,
may be helpful in these cases. Curcumin has been found to slow
down Phase I and speed up Phase II. It has also been shown
to have exceptional anticancer qualities. So for those who
find themselves sensitive to environmental toxins, like second-hand
smoke, eating lots of curry dishes which contains curcumin
may be beneficial. Capsaicin from red chili pepper, naringenin
from grapefruit, and eugenol from clove oil are other Phase
I inhibitors.
Another compound that has powerful anticancer effects, as
well as being able to stimulate enzymes in both Phase I and
Phase II detoxification is indole-3-carbinol. It is found naturally
occurring in broccoli, cauliflower, cabbage, and brussels sprouts.
Along with supporting the liver, indole-3-carbinol helps to
eliminate cancer-causing chemicals throughout the digestive
tract.
Genetic Factors
Occasionally there are those who are genetically predisposed
to sluggish livers. These genetic defects cause adverse changes
to occur in the enzymes that are involved in detoxification.
Susceptibility to damages in the body due to internal and external
toxins can be caused by one or more of about 50 inherited enzymatic
defects.
For instance, there is a small part of the European and Asian
communities that are affected by a genetic defect in the debrisoquine
hydroxylase enzyme. This defect slows the rate of drug and
chemical detoxification. Lung cancer and Parkinson’s
disease have been found to be related to this enzyme defect.
Many of those with food sensitivities have been found to have
defects in the gene that creates the liver enzyme that metabolizes
the chemical S-carboxymethyl cysteine. And a study performed
in Turin, Italy, showed that those with certain liver enzyme
deficiencies had higher risks of bladder cancer.
This variability in enzymes is why certain individuals abilities
to eliminate cancer-causing chemicals is better than others.
This explains why some people can drink alcohol and smoke cigarettes
and live to a ripe old age while others develop cancer after
only a few decades of abuse.
COMPARATIVE STUDY BETWEEN A COMPLEX
OF FLAVONOIDS AND POLYPHENOLS CREATED FROM EXTRACTS OF ARTICHOKE
AND SARSAPARILLA (“ABC Health System Liver Support” formula)
AND A PLACEBO IN ALCOHOL RELATED LIVER DISEASE
INTRODUCTION
Currently there is much interest in the health benefits of
various phytochemicals. Many of the protective qualities of
foods have been attributed to the antioxidant capabilities
of such nutrients as the carotenoids, tocopherols, and Vitamin
C. Recent research, however, points to a specific group of
C15 aromatic plant pigments, called flavonoids, which offer
many active principles in medicinal plants. This group of aromatic
compounds includes the chalcones, dihydroflavones (flavanones),
flavones, isoflavones, biflavonoids, dihydroflavonols, flavonols,
anthocyanidins, and proanthocyanidins. Presently there are
over 4000 individual flavonoid compounds known.
A single plant may contain several flavonoids with distribution
being specific to various parts of the plant. Flavonoids play
different roles in each part of the plant. For instance, because
of their attractive colors, flavonols, flavones, and anthocyanidins
are helpful in signaling pollinating insects. Catechins and
other flavonols have astringent qualities that protect the
plant by keeping other insects away. Some flavonoids have UV-absorbing
properties and protect the plant from harmful UV radiation
from the sun. While others participate in the light phase of
plant photosynthesis.
Historically, flavonoids have been described for treating
diabetes mellitus, allergy, cancer, viral infections, headache,
stomach and duodenal ulcer, liver pathology, and inflammation.
They can bind to enzymes, hormone carriers, and DNA; chelate
metal ions such as iron, copper, zinc, and manganese; catalyze
electron transport; and scavenge free radicals. Most researchers
conclude that the pharmacological effect of flavonoids is due
to their inhibition of certain enzymes, their metal chelating
abilities, and to their antioxidant activity.
The “UMN Liver Support” formula is a complex
of flavonoids and polyphenols created from extracts of the
artichoke (Cynara floridanum) and sarsaparilla (Smilax aristolochiaefolia).
It was created by a group of three researchers specializing
in pharmacology, plant chemistry, and liver disease. It has
been used clinically for almost 20 years in various private
medical settings throughout Central and South America with
favorable results in addressing many liver and gall bladder
disorders. A comprehensive chemical analysis has not been performed
at this time. However, a partial analysis for certain flavonoids
and polyphenols has been accomplished. This analysis has shown
levels of quercetin, kaempferol, isorhamnetin, (+)-catechin,
silymarin, cynarin, caffeic acid, and chlorogenic acid.
The artichoke has been used historically in the United States
and Europe to treat such conditions as sluggish liver, poor
digestion, atherosclerosis, elevated triglycerides and cholesterol,
decreased bile secretion, kidney diseases, and proteinuria.
In Honduras and Mexico, sarsaparilla is used to treat rheumatism.
And in the United States and China, it has been used to treat
arthritis, cancer, skin disease, venereal disease, fevers,
and digestive disorders. And in one Chinese study, sarsaparilla
was found to be 90% effective in treating syphilis.
After years of research with patients in private clinics,
it was decided to evaluate the ingredients found in the “UMN
Liver Support” formula with a randomized double blind
placebo study. Patients chosen for this study were those who
had been diagnosed with chronic alcoholic liver disease caused
by excessive ingestion of alcohol (excessive ingestion being
defined as one (1) to one and one half (1 ½) liters
of tequila or brandy per day for extended periods of time).
The patients were diagnosed and chosen in the Clinic par la
Attention de Problemas Relacionados con el Alcohol (CAPRA)
at the General Hospital in Mexico City, which belongs to the
Secretaria de Salud (Equivalent to the U.S. Department of Health).
(Translation: Clinic for the Attention of Problems Related
to Alcohol)
METHODOLOGY
The study chosen was a randomized double blind placebo study
in which neither the treating physicians in charge or the patients
knew to whom the real product or the placebo was administered.
Sixty (60) patients were divided in a random way into two (2)
groups of thirty (30) each. Of these sixty test subjects, 53
were male and 7 were female with ages running from 26 years
of age to 52 years of age (average age 37.3 years). All of
the patients had tests made of liver performance, hepatic cytology,
blood analysis, prothrombin time, urine tests, and clinical
examination. These same tests were completed again at the end
of the study. The treatment lasted thirty (30) days and each
patient took three capsules (420 mgs. each) three times per
day.
DEFINITION OF PARAMETERS AND RESULTS EXPRESSED IN PERCENTAGES
To make this report useful and keep misinterpretations to
a minimum, it was important that we defined the following clinical
parameters, laboratory analysis, and results in a clear and
simple way. The following results have been expressed in percent
improvement, which was determined using two indices, the Maddrey
and Orrego (see references below). Results were measured before
and after treatment, calculating the difference, and expressing
these results as a percentage of recuperation.

Ascites
Ascites is the effusion and accumulation of serous fluid
in the abdominal cavity. It is found commonly in those diagnosed
with liver disease.
A 72.38% reduction of ascites was observed in the experimental group. The placebo
group experienced a 6.35% increase in abdominal fluid.
Encephalopathy
Encephalopathy is a degenerative disease of the brain. Hepatic
encephalopathy is a condition usually occurring secondarily
to advanced disease of the liver. It is marked by disturbances
of consciousness, which may progress to deep coma (hepatic
coma), psychiatric changes of varying degree, flapping tremor
and fetor hepaticas. It is also referred to as portal-systemic
encephalopathy.
A 66.08% reduction of encephalopathy was obtained in the experimental group.
The placebo group saw a 12.24% increase in these symptoms.
Splenomegaly
Splenomegaly is enlargement of the spleen. Congestive splenomegaly
often results from cirrhosis of the liver and is also characterized
by anemia and hemorrhages.
A 88.40% reduction in spleen enlargement was noted with the treated group.
The placebo group worsened by 11.54%.
Hepatomegaly
Hepatomegaly is enlargement of the liver. It is seen as a
result of cirrhosis, fatty infiltration, passive congestion,
and early biliary obstruction.
The treated group experienced a 93.33% reduction in enlarged livers. In the
placebo group their livers continued to enlarge by another 7.14%.
Weakness
Weakness is defined as lacking physical strength or vigor,
asthenia, atony, cardiasthenia, fatigue, and lassitude.
The treated group noted a 73.64% increase in strength. There was a decrease
in muscle strength in muscle strength by 7.41% in the placebo group.
Peripheral Edema
Peripheral edema is a condition in which the peripherals
body tissues contain an excessive amount of tissue fluid. It
results from increased permeability of the capillary walls
due to possible disturbances in renal functioning, reduction
of plasma proteins, fluid and electrolyte imbalances, and malnutrition.
Edema in the extremities of the treated patients decreased by 48.21% in the
treated group. There was no change in the placebo group.
Hemorrhages
Hemorrhaging is bleeding. Many alcoholics present with massive
upper GI bleeding from esophageal varices secondary to portal
hypertension (increased pressure in the portal vein as a result
of obstruction of the flow of blood through the liver).
The treated group noted a 100.00% decrease in capillary hemorrhaging in the
skin, gums, and nasal membranes. The placebo group saw an increase of 28.57%
in hemorrhaging.
Anorexia
Anorexia is defined as loss of appetite. Anorexia is seen
in depression, malaise, commencement of fevers and illness,
also in disorders of the alimentary tract, especially the stomach,
and as a result of alcoholic excesses, drug addiction or certain
medicines.
Anorexia decreased in the treated group by 76.98%. The placebo group noted
a decrease of 3.70%.
Abdominal Wall Veins
Abdominal Wall Veins are very tortuous (having many twists
or turns) veins visible throughout the abdomen of the patient.
Related to ascites.
The experimental group saw a 60.62% reduction while the placebo group experienced
a 3.33% reduction.
Palmar Erythema
Palmar erythema is reddish and swollen palms due to muscular
hypotrophy (progressive degeneration and functional loss of
cells and tissues).
The Liv-1 group experienced a 26.67%% reduction in palmar erythema and there
was no change with the placebo group.
Telangiectasia
Telangiectasia is a vascular lesion formed by dilatation
of a group of small blood vessels of the skin.
The Liv-1 group saw 60.00%% reduction in these lesions. While in the placebo
group there was a 3.33% reduction.
Total Bilirubin
Bilirubin is the predominant pigment of human bile and it
gives the bile a golden yellow color. Total serum bilirubin
may be increased in cirrhosis of the liver and acute viral
hepatitis.
The experimental (Liv-1) group saw a 38.95% reduction in total bilirubin and
the placebo group saw a 5.68% increase.
Alkaline Phosphatase
Alkaline phosphatase is an enzyme that hydrolyzes monophosphoric
esters liberating inorganic phosphate. Its optimum pH is about
9.0 (alkaline) and functions in the mineralization process
of bone. It is excreted by the liver; hence its levels increase
in the blood whenever an obstructive liver condition exists.
Patients taking the Liv-1 obtained a 25.91% reduction in alkaline phosphatase
blood levels and the placebo group saw an increase of 11.69%.
Serum Glutamic Oxaloacetic Transaminase (SGOT)
Oxalacetic glutamic transaminase is an enzyme distributed
throughout all tissues, but especially found in high concentrations
in the heart and liver. OGT is increased in cases of hepatitis,
hepatic necrosis, cirrhosis, and hepatic metastasis. SGOT is
now more commonly referred to as aspartate aminotransferase.
The treated group noted a decrease of 23.83% in SGOT levels. The placebo group
experienced a worsening of 11.71%.
Prothrombin Time
Prothrombin time is a test of clotting time made by determining
the time for clotting to occur after thromboplastin and calcium
are added to decalcified plasma.
There was a decrease in prothrombin time in the experimental group of 42.00%.
An increase in clotting time was noted in the placebo group of 6.60%.
Serum Albumin
Serum albumin is one of a group of simple proteins widely
distributed in tissues; it is found in the blood. Low levels
of albumin in blood plasma are associated with a pathologic
condition of the liver.
The experimental group saw an increase in serum albumin of 37.27%. There was
a decrease in the placebo group of 1.95%.
Gamma Glutamyl Transpeptidase (GGT)
GGT is a tissue enzyme that is elevated in many conditions
involving hepatic damage including alcohol-induced hepatic
injury; in patients with renal disease, pancreatitis, diabetes
mellitus, and coronary artery disease.
The treated group noted a reduction of 23.79% in GGT. The placebo group experienced
an increase of 9.92%.
Conclusion
Many of the most common symptoms of headaches, mental confusion,
muscle pain, fatigue, poor coordination, nerve problems, skin
irritations, and emotional imbalances can be a result of over
exposure to toxins. Our bodies have become the final resting
place of many dangerous poisons found throughout our environment.
Even those who lead a relatively environmentally clean existence
can become overwhelmed with internal toxins produced as a result
of emotional traumas and microorganisms. However, in spite
of the fact that our bodies are being deluged each day with
external and internal toxins, we can still experience relatively
good health if we make the efforts to clean up our internal
environment.
In addition to the nutrients mentioned in this article, here
are a few other suggestions that can be helpful. Drinking distilled
water can help leach many of the metallic chemicals that accumulate
throughout the body. Hot baths or saunas while using a loofah
sponge to stimulate blood supply can help rid poisons through
the skin. There are some great oral chelation formulas available
today that can remove toxins and plaque that accumulate on
the inside of blood vessels leading to atherosclerosis and
heart disease. Adding more raw fruits and vegetables to your
diet helps to provide enzymes necessary for detoxification
and a short two or three day vegetable juice fast can quickly
help to detoxify the liver. Eliminating alcohol and drugs,
except those prescribed by your physician, is critical for
optimal detoxification. And eliminating highly refined and
processed foods, high sugar foods, and foods with hardened
fats will surely give your liver the rest it so sorely needs.
