HYPERGLYCEMIA
Field of Invention
The present invention relates to an edible therapeutic herbal composition for treating hyperglycemia agent for lowering the blood glucose levels in mammals, especially humans, suffering from diabetic mellitus. Background of the Invention
Diabetes mellitus is an insidious medical condition for which there is no permanent cure. Across the globe many humans are suffering with this disease and with its implications such as heart attacks, strokes, loss of eyesight, difficulty in wound healing, more susceptible to disorders of aging and such conditions worsening to death. The onset of diabetes can occur in early age of life although many people are getting in much later par! of life.
The medical condition of diabetes characterized by the inability of the pancreas gland to secrete "insulin". Insulin is produced in the body by the beta cells of pancreas gland and helps in the metabolism of glucose to produce the energy required by the humans. In the diabetic patients the pancreas gland deteriorates and the beta cells arc loo small and insufficiently numerous to produce a proper amount of insulin. Hence the sugar is not properly metabolized to produce energy. As a result, diabetic patient experience an elevated levels of sugar in the blood. The diabetes can be broadly categorized into IDI ).\1 and N1DDM. Roughly "IDDM" refers to insulin dependent diabetes mellitus or type I wherein, anti-bodies destroy .beta.-cells of islets of Langerhans which produce insulin and hence very low and no insulin levels in the circulation. In NIDDM there is no loss or moderate reduction in .beta.-cell mass and is due to abnormality in gluco-receptor of .beta.-cells, reduced sensitivity of peripheral tissues to insulin.
The conventional treatment of IDDM involves the administration of insulin to a patient typically by means of injections. These injections must be performed on a regular basis and are normally administered by an hypodermic needle. This is inconvenient to a patient since the administration of insulin using hypodermic needle

requires both a suitable place and time to perform the injection, apart from a great
deal discomfort to the patient. Also, if the amount of insulin is excessive for amount
of sugar in the blood, the patient can undergo insulin shock. If a patient is unwilling or
not able to accept insulin injections, pharmaceutical preparations containing oral antidiabetic
drugs such as sulfonylureas (Glibinclamide, Gliquidone etc.) or biguanides
(metformin, phenformin) or insulin sensitizers such as troglitozones could be taken.
All in all, the patient is constantly on the narrow edge of either too much or
insufficient medication and frequently is not able to tolerate such medication because
of its side effects.
To control proper blood sugar levels there by controlling this dysfunction so as
prevent eventual complications, insulin independent diabetics must maintain a
regulated diet control and exercise. Unfortunately most of the diabetics experience to
great of difficulty to follow such restrictions leading to worsening of associated
complications. Further more, treating with insulin never cures this disorder and there
is an urgent need to treat this disease with natural products, which have the
advantages of patient compliance and least side effects compared to synthetic
medicines. The usage of herbs in the treatment of medical ailments has been a
tradition in many countries like India, china etc for so many years, and several
diseases can be cured without any side effects.
Hypoglycemic efficacy of different parts of Azadirachta indica was evaluated
by different researchers (Sonia & Srinivas, 1999, Santoshkumari and Devi, 1990,
Murty et.al., 1978, Dixit et.al., 1986, Shukla et.al., 1973, Jain, 1984). Hypoglycemic
effects of (-)-epicatchin (Chakravarthy et. al. 1982), Gymnesma sylvestre (Asha et. al.
1981), Trigonella foenum graecum (Khosla et. al. 1995) have been reported. Herbal
composition containing different compositions of Trigonella foenum graecum,
Nigella saliva, Orgnanum vulgare, Rosmarinus officinalis, Lupinusterms, Lawsonia
inermis and Foemiculum vulgare and methods to treat diabetes mellitus were
described in USPTO 6,042,834 (Baraka,2000). Hypoglycemic extracts for treating
diabetes which were obtained from different species of genus Eugena of myrtaceae
family were disclosed in USPTO Pub. No. US 2001/0021401 Al (Sharma et.al.
2001). Similarly medicinal
compositions, described as pancreas tonic, containing Epicatechin (pterocarpus
marsupium), gymnemic acid (gymnema sylvestre) along with other plant products
such as Cinnamomum tamala, Momardica charantia, Aegle marelose, Syzygium
cumini, Trigunella foenum graceum and Azadirachta indica, Tinospora cordifolia,
Ficus racemosa was described in US application 5,886,029 (Dhaliwal,1999). A
different herbal edible composition containing Syzygim cumini, Gymne sylvestre,
Momordica charantia and Solanum melogena was described in US PTO 5,900,240
(Tomer et.al. 1999).

Detailed description of the invention:
The present invention provides a composition consisting of five different herbs
for treatment and controlling diabetes mellitus, more particularly to non-insulin
dependent diabetics. This herbal composition consists of Prunus amygdales, Ocimum
sanctum, Azadirachta indica, Aegle marelose and Vitus vinefera. These plants may be
found in various places in the world. The composition containing mixture
(Composition Fl in Table 1) of dried form of leaves of Azadirachta indica, leaves of
Ocimum sanctum, fruit of Prunus amygdalus, leaves of Aegle marelose and fruit of
Vitus vinefera is particularly preferred. In another embodiment of the present
invention, the active ingredients are taken from the any parts of the plants mentioned
as above. The ratio of each ingredient is not very critical and 15-40% w/w of one
ingredient is taken and is balanced with the ingredients of at least two to all four
herbs. The dietary compositions are made with dried plant parts after proper milling to
get fine powder and formulated to suitable oral dosage forms.
By using these five different herbs, various compositions (F1-F9) were
prepared comprises compositions with 15-40% w/w of all or at least three herbs. The
plant ingredients are either in raw form or as medicinal extract of plant parts, and are
administered to experimental subjects (both diabetic and normal rats with elevated
blood glucose levels and non-insulin dependent diabetic humans) at a dose of 0.01 -
0.5 gm/Kg body weight. The dosage to be administered is not critical and could be
varied depending on status of the disease, diet of the subjects and nature of the
subjects (animal or human), age, sex, bodyweight, and physical condition. The dose
of dietary compositions made of raw ingredients is little higher than those obtained by
extraction procedures, and overdoses of these dietary compositions is not a problem.
The extraction methods are known to the person skilled in the art. Generally a subject
receives their own dose after some initial dosing to maintain normoglycaemia and
then such doses will be continued until some steady states are obtained. The herbal
compositions were preferably in suspension form. The herbs were milled to fine
powder, mixed and then prepared suspension with distilled water. The powder can be
used to prepare different oral dosage forms. Although ingredients of compositions
itself has good product stability characteristics, the herbal composition may contain
some inert ingredients as required for oral dosage forms. Although, suitable oral
dosage forms are formulated and administered, the preferable dosage form is a
suspension of the said herbal composition.
The mechanism by which the herbal composition of the invention operates is
not exactly understood. However it is assumed that the herbal composition stimulates
the pancreas to make its own insulin or assists in some healing mechanism of the
diseased pancreatic tissue. The herbs are stimulant to the pancreas and cause the cells
of the pancreas to respond and to recommend production of insulin. Since this
composition of present invention is holistic in nature and represent in dietary
supplements and hence overdosing would not be a problem. And there are no dangers
or side effects associated with treatment with this herbal remedy of the invention. The
herbal composition also produces beneficial effects such as diuretic, stomachic,
antiulcers.

herbal formulation and glibenclamide on oral glucose tolerance tests in rats.
The invention is described in detail herebelow by the following examples which are
meant to illustrate the invention and should not be construed as limitations
Compositions
Various compositions with permutations and combination were tried (Table-1)
using Azadirachta indica.Prunus amygdales, Ocimum sanctum , Aegle marmelos and
EXAMPLE-1
Male albino rats of wistar strains (150-200 g) were used throughout the
studies. Rats were divided into eleven groups of each containing 6 rats. These
animals were randomly assigned to the following groups which include (A) control
group, (B) standard group (glibenclamide, 3mg/Kg) and (C) test groups (F1-F9).
Diabetes was induced by injecting streptozocin (STZ) in a dose of 65 mg/kg intra
venous in 0.1M citrate buffer. Rats were kept fasted overnight but were given water
ad libitum. After 48 hours of STZ injection, blood samples were taken from tail vein
of conscious rats. The blood was centrifuged at 5000 rpm for 10 minutes in an
eppendorf tubes containing EDTA (1 mg/ml of blood). Plasma glucose estimations
were done by glucose oxidase method by using Auto blood analyzer (Techinicon RA-
100, Bayer Diagnostics, Ireland). Animals with blood glucose level more than 250%
of the fasting level were considered to be diabetic and were used for the experiment.
Group A was given normal saline, group B was given glibenclamide and various
groups of C were given herbal compositions for 15 days at least once in day. Blood
was collected from tail veins of all the rats after 7 days and 15 days of treatment and
glucose levels were estimated as described previously (Table 2). The statistical
analysis was performed using Prism program (Graphpad software). ANOVA with
post Newman - Keul test with P values was used to compare the treatment efficacy
between the test groups.
Significantly higher compared to control group (P Significant anti-diabetic activity was found in the compositions tested.
Fl was found to be most effective out of all the composition tested, which is
significantly higher than standard groups, although other groups showed considerable
activity.
EXAMPLE 2: GLUCOSE TOLERANCE TEST (GTT)
From the above STZ induced diabetic model the composition 1 has chosen for
GTT study.
Male albino rats of wistar strains (150-200 g) were used. They were divided
into three groups each containing 6 rats. They were randomly assigned A) control
group B) standard group (glibenclamide) C) test group. Group A was given saline,
group B was given glibenclamide (3 mg/Kg) and group C was given test
compositions. After 2 hours all rats were loaded with glucose with a dose of 5g/kg.
Blood samples were taken from tail vein of conscious rats for every 30 minutes up to
3 hours. Plasma glucose estimations were done by glucose oxidase method by using
Auto Blood Analyzer as described in Figure 1. The statistical analysis was performed
using Prism program (Graphpad software). Annova with post Newman - Keul test
with P values was used to compare the treatment efficacy between the test groups.
Although activity of the test composition is significantly higher, both
composition Fl and glibenclamide showed increased (P compared to control group.
EXAMPLE-3
In this example the composition-1 was tested on humans. Five non-insulin dependent
diabetic male patients aged 45-55 years old and an average body weight of 68 ±5 kg
were given composition Fl at a dose of 0.1 gm/Kg for 30 days daily in 3 divided
doses, half and hour before breakfast, lunch and dinner. The fasting blood glucose
level was monitored for every five days starting from day zero. The results of this test
are shown in table-3. Considerable reduction in the blood glucose levels were
observed in all the individuals although the response varied significantly. It is
concluded that some changes in dosage regime and diet would give a proper control
of diabetes in non-insulin dependent diabetic patients. It is assumed that, these herbal
compositions could be used in type I diabetic patients along with insulin therapy as
ingredients of this compositions could increased peripheral insulin sensitivity, and
hence insulin dose could be reduced.
