Health foods supplementary for treatment and prevention of
constipation
TECHNICAL FIETD
The present invention relates to health supplementary food for improving
constipation, more particularly, health supplementary food containing Auricularia
auricula, which is effective in prevention and treatment of constipation by loosening the
bowels and stimulating bowel movements.
BACKGROUND OF THE INVENTION
Constipation is a symptom that stool is very hard and dry compared with normal
condition, and the frequency of bowel movements and amount of feces are decreased,
thereby causing discomfort and physiological disorder. Most of constipation is habit-
forming constipation. It is divided to hypertonic- and hypotonic constipation, depending
on a symptom. In case of the hypotonic constipation, strain of large intestines weakens
and the bowel movements come to slow. Accordingly, fecal moisture content is
decreased, being dull to a reflex of the bowel movements. While, in case of the
hypertonic constipation, peristalsis in large intestines accelerates and a spasm in intestinal
wall occurs, so that stools in form of small lumps or stick that is as thick as a pencil may
be excreted. Constipation may be caused by temporary factors related to changes in
enviroriment and diet during travel, etc. In addition, constipation may be caused by
rectal cancer, rectal stricture, lesion around the rectum, chronic colitis, or acute illness in
digestive system.
Meanwhile, when fibers lack in dietary intake, feces may be tightened in weight,
leading readily to constipation. However, if a lot of fibers are included in diet, enough
moisture may be absorbed into intestines. Accordingly, feces increase in amount, which
promotes the bowel movements. As above-mentioned, fibers stimulate the intestines.
Besides, since the fibers have a lot of moisture, stools are not hard, leading to loosen the
bowels. Moreover, carcinogens, cholesterol, and many other toxic substances in the
intestines are absorbed into fibers and promptly discharged from human body. Intestinal
bacteria decompose fibers in diet, to generate hydrogen-, methane- and carbon dioxide gas,
etc. The gases strengthen stimulation into the intestines, thereby activating peristalsis in
the intestines. Therefore, the simplest and easiest method for prevention and treatment
of constipation is to take foods with enough fibers suitably.
The other method for treatment of constipation is to make an effort to have
regular bowel movements in every morning and to eat cold water or carbonated water, or
to take moderate exercise in early morning.
hi addition, laxatives such as magnesium phosphate, fenobarin, sena, Rhubarb
(Rheum unduiatum) and the like may be used as a drug. As occasion demands, an
enema may be given.
Recently, researches have been carried out on foods to improve constipation
using various kinds of natural foods or natural medicines in order to prevent constipation.
Korean Patent No. 15879 disclosed a tea too improve constipation using natural
medicines such as alvae Semen, Pleuropterus multfloiiis, Geranium nepalense subsp.
Thunbergii, fig tree, Polygonum aviculare, rhubarb (Rheum unduiatum), etc. Besides,
Korean Patent No. 32660 disclosed a drug to treat constipation using Lycium chinense
MILL, and maize (Zea mays L.) However, the drug for treating constipation that can be
utilized as food, has been not yet met the requirements. For that reason, the development
of food for preventing and treating constipation has been necessary urgently.
Therefore, the present inventors have studied on studied on food that is effective
in constipation using natural foods. As a result, the present inventors completed the
present invention by manufacturing health supplementary food that is effective in
improving constipation with an Auricularia auricula rich in fibers and natural gelatins,
and a laxative such as a cascara sagrada The said health supplementary food can
increase fecal excretion and stimulate bowel movement by the two ingredients,
Auricularia auricula and the laxative, respectively.
DISCLOSURE OF THE INVENTION
The purpose of the present invention is to provide health supplementary food that
is effective in improving constipation by increasing fecal excretion and stimulating the
bowel movements.
To accomplish this purpose, the present invention provides health supplementary
food for improving constipation containing Auricularia auricula as an active ingredient.
In addition, the health supplementary food for improving constipation according
to the present invention further may include cascara sagrada, and a powder of mulberry
leaves or magnesium hydroxide.
All amounts in this specification are % by weight (w/w) of the health
supplementary food, unless otherwise noted
Hereinafter, the present invention will be described in detail.
The health supplementary food according to the present invention contains
Auricularia auricula rich in fibers as an active component.
In Auricularia auricula, natural gelatins as well as the above fibers are also
plentiful. Therefore, in the presence of exposure to water, Auricularia auricula swells
and its volume increases 5-6 times. By this property of Auricularia auricula, fecal
excretion may be increased, accordingly, Auricularia auricula may have an effect on
improvement of constipation
Furthermore, the health supplementary food according to the present invention
may include the following ingredients as a bowel-stimulator together with Auricularia
auricula: lubricants such as mineral oil and olive oil; bulk forming agents such as
psyllium and aloe; the small intestine-stimulants such as castor oil and calomel; and the
large intestine-stimulants such as cascara sagrada, dulcolax and bicogreen, etc. However,
the lubricants can cause disorder of nutrient-adsorption with prolonged daily use and the
bulk forming agent should be taken with water. Therefore, it is desirable to use cascara
saqrada as the stimulants. It was known that cascara sagrada, a derivative of hydroxy
anthracite, acts on the large intestines to stimulate the bowel movements and on the nerve
through a blood vessel to facilitate purgative effects.
Where the cascara sagrada is added into Auricularia auricula, it is preferable that
the cascara sagrada and Auricularia auricula are present in the range of 10-40% and 60-
90% by weight, respectively. If the amount of Auricularia auricula exceeds 90% by
weight, it raises discomfort such as abdominal distention caused by the excessive intake.
While, if it is below 60% by weight, it has a little effect on an improvement of
constipation caused by the insufficient amount. Therefore, it is desirable that the amount
of Auricularia auricula is in the above-mentioned range.
The cascara sagrada is resolved in the intestinal tract, and then stimulates a
mucous membrane of the intestines to cause vermiculation, thereby loosening the bowels.
However, if its amount exceeds 40% by weight, it stimulates the large intestines to undue
extent, thereby causing diarrhea and stomachache. Therefore, it is preferable that the
amount of the cascara sagrada covers above-mentioned range.
Meanwhile, the health supplementary food containing Auricularia auricula
according to the present invention may further include a powder of mulberry leaves as
well as the cascara sagrada According to the reports, the powder of mulberry leaves
abounds in minerals such calcium, iron, etc. and dietary fibers. It has been investigated
that the dietary fibers are present in green tea in amount of 10.6%, whereas in the powder
of mulberry leaves in amount of 52.9%. Preferably, the health supplementary food may
further include the powder of mulberry leaves, particularly, in amount of 10-30% by
weight.
hi addition, the health supplementary food containing Auricularia auricula
according to the present invention may further include saline agents such as magnesium
sulfate, magnesium carbonate, magnesium hydroxide, etc., as well as the cascara sagrada.
The saline agents prevent moistures from being absorbed into the bowel wall, causing
diarrhea. Particularly, it is preferable that the amount of magnesium hydroxide is present
in the range of 5-15% by weight. If the magnesium hydroxide exceeds 15% by weight,
it may cause diarrhea Therefore, it is preferable that the amount of the magnesium
hydroxide covers the above range.
The health supplementary food containing Auricularia auricula according to the
present invention may be manufactured in the form of liquid, powder or granule, more
preferably, granule, to sell. A concrete manufacturing process comprises the following
steps: selection of materials; mixing of materials; production of granules; drying; and
packing.
First, each material of the standard quality is selected and mixed in together
according to the common method known to the present art. Ingredients generally
required for formation of granule, for example, water, alcohol and crystal cellulose, are
added to the above mixture of materials, thereby producing granules. The produced
granules are dried in the airtight dryer. It is preferable that granules are dried at 35-45 °C
for l-2hrs. Particularly, granules are airtightly wrapped in fourfold papers to sell. The
health supplementary food produced in this manner may be taken anywhere easily and
conveniently. The health supplementary food also has an advantage of facility in
keeping.
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention is more specifically illustrated by the following
examples.
However, it should be understood that these examples are provided only for
illustration of the present invention, but not intended to limit the present invention in any
manner.
<Example 1>
hi order to corrfirm the effect of Auricularia auricula on constipation, in v 'o
assay was performed with 8-weeks old Sprague-Dawley male rats.
First, in order to induce constipation, 14 rats were fed with a inhibitor of bowel
movements, loperamide(1.5nig kg, Sigma) diluted in 0.9% saline solution at AM 9:00
and PM 6:00, twice daily for 5 days, to inhibit evacuation. The constipation-induced rats
were then fed with a 20mg of Auricularia auricula extract at AM 9:00 and PM 6:00,
twice daily for 5 days.
During the experimental period, 5 days, food intake in each rat was measured
daily. At 3 day and 5 day after feeding, body weight of each rat was measured.
Results are shown in tables 1 and 2, respectively. E)uring the experimental period, all
feces excreted from each rat were also daily collected in polystyrene tube at AM 9:00 and
lyophilized to measure a dry weight. Feces excreted from rats at AM 9:00 at 2, 4 and 5
day after feeding were put in micro tube, and then weight of moisture-contained feces and
lyophilized feces were measured respectively. Fecal moisture content was measured by
calculating the difference of weights in the two forms of feces. Results are shown in
table 3.
<Example 2>
3g of Auricularia auricula and 1.5g of cascara sagrada were mixed to prepare a
composition. 20 mg of the composition was fed to 14 constipation-induced rats,
respectively. Except this, food intake, change in weight, amount of feces and fecal
moisture content were measured as described in Example 1. Results are shown in tables
1 to 3, respectively. The prepared composition included 66.6% of Auricularia auricula
and 33.4% of cascara sagrada
<Example 3>
4.875g of Auricularia auricula, 1.5g of cascara sagrada and 1.125g of powder of
mulberry leaves were mixed to prepared a composition. 20mg of the composition was
fed to 14 rats having constipation induced by loperamide. Except this, food intake,
change in weight, amount of feces and fecal moisture content were measured as described
in Example 1. Results are shown in tables 1 to 3, respectively. The prepared
composition included 65% of Auricularia auricula, 20% of cascara sagrada and 15% of
powder of mulberry leaves.
<Example 4>
4.875g of Auricularia auricula, 1.5g of cascara sagrada and 1.125g of
magnesium hydroxide were mixed to prepared a composition 20mg of the composition
was fed to 14 rats having constipation induced by loperarnide. Except this, food intake,
change in weight, amount of feces and fecal moisture content were measured as described
in Example 1. Results are shown in tables 1 to 3, respectively. The prepared
composition included 65% of Auricularia auricula, 20% of cascara sagrada and 15% of
magnesium hydroxide.
<Comparative Example 1>
8-week old Sprague-Dawley male rats were fed with only 0.9% saline solution.
Rats to the number of 14 were used in this experiment. Food intake, change in weight,
amount of feces and fecal moisture content were measured as described in Example 1.
Results are shown in tables 1 to 3, respectively.
<Comparative Example 2>
8-week old Sprague-Dawley male rats were fed with loperarnide. Rats to the
number of 14 were used in this experiment. Food intake, change in weight, fecal
excretion and fecal moisture content were measured as described in Example 1. Results
are shown in tables 1 to 3, respectively.
[Table 1]
Measurement of food intake
As shown in table 1, food intake was decreased in rats of Comparative Example 2
that had not been given any treatment after induction of constipation, compared with in
rats of Comparative Example 1, control. Whereas, it was not almost changed in rats of
Example 1 that were fed wimAuricularia auricula extract. In addition, in rats of Example
2 that were fed with the composition of Auricularia auricula and cascara sagrada, rats of
Example 3 that were fed with the composition of Auricularia awicula, cascara sagrada
and powder of mulberry leaves, and rats of Example 4 that were fed with the composition
of 'Auricularia auricula, cascara sagrada and magnesium hydroxide, food intake was not
changed during the experimental period.
[Table 2]
Measure of change in body weight
As shown in Table 2, body weight was decreased in rats of Comparative Example
2 that had not been given any treatment after induction of constipation, compared with in
rats of Comparative Example 1, control. Whereas, it was not almost changed in rats of
Example 1 that had been fed wϋhAuricularia auricula extract In rats of Example 2 that
had been fed with the composition of Auricularia auricula and cascara sagrada, rats of
Example 3 that had been fed with the composition of Auricularia auricula, cascara
sagrada and powder of mulberry leaves was fed, and rats of Example 4 that we had been
fed with the composition of Auricularia auricula, cascara sagrada and magnesium
hydroxide, body weight was not changed.
[Table 3]
Effect of each composition on constipation
As shown in Table 3, an amount of feces was remarkably increased in rats of
Example 1 that had been fed with Auricularia auricula after induction of constipation
with loperamide, compared with in rats of Comparative Example 2 that had not been
given any treatment aftα induction of constipation. Fecal moisture content was also
increased, hi addition, the amount of feces and fecal moisture content was increased in
rats of Example 2 that had been fed with the composition of Auricularia auricula and
cascara sagrada, rats of Example 3 that had been fed with the composition of Auricularia
auricula, cascara sagrada and powder of mulberry leaves, and rats of Example 4 that had
been fed with the composition of Awicularia auricula, cascara sagrada and magnesium
hydroxide.
From the results of in vivo experiments, it was corrfirmed that Auricularia
auricula extract according to the present invention has an excellent effect on constipation-
improvement hi addition, it was corrfirmed that the effect of constipation-improvement
was increased when cascara sagrada and powder of mulberry leaves were further added to
Auricularia auricula extract.
