"A COMPOSITION OF HERBAL EXTRACTS FOR PROMOTING GROWTH AND DEVELOPMENT"
|Abstract||This invention relates to an herbal composition for growth and development consisting of extracts of Withania somnifera, Embilica officinalis, Bacopa monniera, Zingiber officinalis. Piper longum. Piper nigrum, Alpinia galanga, and Foeniculam vulgare. Extracts of the plants may be obtained by treating the plant material with pharmaceutically acceptable solvents or by steam distillation followed by concentration of the extract. The compositions of the invention are useful for the treatment or prophylaxis of diseases or conditions, which are characterized by decreased appetite, endurance and cognitive functions.|
This invention relates to a composition of herbal extracts for promoting growth and development. This composition is particularly, though not exclusively useful in promoting growth and development of children.
Mothers of young children often complain about lack of appetite and decreased intake of food. Studies on nutritional status of pre-school and school going children have revealed malnutrition even among children of better socio economic status. Under weight, decrease physical stamina and cognitive learning skills have also been reported. Direct co-relation between nutritional status and learning abilities of children have also been established.
Many compositions and methods are described in the Ayurvedic and Siddha medical literature for appetite stimulation. Class of drug called Deepana and pachana are listed in Ayurveda. Panchadeepakani churanam and Trikatu churan are some examples. The dose of individual Botanicals are given in the Indian Herbal Pharmacopoeia and German - E Monographs. The doses on dried weight basis of herb suggested are as under
Withania somnifera 3-6gm IHP
Embilica officinalis - 3-6gm IHP
Bacopa monnieri - 5-lOgm IHP
Zingiber officinalis - l-2gm IHP - 2-4gm Commission-E Monograph
Piper longum - 4.5-9gm IHP
Piper nigrum 4.5-9gm IHP
Alpinia galanga l-2gm IHP
Foeniculum vulgare 10-40gm IHP
Most herbs have been investigated individually and some in combination with Spice mixtures have also been investigated. Most of the studies was focused on specific needs in isolation and the need for Synergy in terms of Growth, Development, Physical stamina, immune building and cognitive learning have not been done together which is desirable of a product.
Food technologies have also developed formulations with spices to enhance appetite commercial products are also available under various brand names both with herbals and with pharmaceutical actives like Cyproheptadine.
But still those formulations have the following short falls
1. They do not completely address the problem of Growth and Development
2. Some are not palatable to children
3. Some products particularly products with Cyproheptadine create adverse effects like sleep and drowsiness
4. Some cause gastric irritation
5. The formulations are not stable in the shelf leading to precipitation of the active plant materials
6. Even the recommended therapeutic doses are very high for individual Botanicals to get the effect.
In order to overcome the above discussed problems, extracts or concentrates of medicinal herbs are formulated. Current list of approved additives for use in Ayurvedic preparation does not include emulsifiers. As such active components of many plant based products precipitate out on keeping, thereby reducing their potency and shelf life. Extracts of ariel part of Bacopa monnieri contains saponins which act
as solubilizers in the composition developed by us and helps in enhanced assimilation in vivo. This also avoids precipitation of any active components on keeping. This invention provides a composition wherein aqueous or pharmaceutically acceptable solvent extracts of herbs are used.
This invention relates to a composition of herbal extracts for promoting growth and development which comprises plant extracts of Bacop monnieri, Embilica officinalis, Withania somnifera (group A), Piper longum, Piper nigrum. Zingiber officinalis, Foreniculam vulgare and Alpinia galanga (group B).
This invention also includes a process for preparing the said composition of herbal extracts comprising the steps of extracting active components from Withania somnifera, Embilica officinalis, Bacopa monnieri (group A), Zingiber officinalis. Piper longum, Piper nigrum, Alpinia galanga and Foreniculam vulgare (group B) and mixing the extracts in the desired ratio to produce an emulsified composition.
The present invention further relates to a pharmaceutical composition in a single dose unit form.
Pharmaceutically acceptable carriers, excipients, flavours and the like may be added to the composition. In this specification the expression pharmaceutical composition includes nutrition and dietary supplements. Plants under group A are herbs and those specified under group B are spices. The extracts and concentrates are in the form of liquids, powders or in paste form.
Plant extracts may be obtained by drying or freeze drying cut plants, roots, fruits, seeds and the like. Parts thus dried may be optionally ground before subjecting them for extraction with food grade solvents, water or mixtures of both. Suitable food grade solvents are propane, butane, butyl acetate, ethyl acetate, ethanol, carbon dioxide, acetone, nitrous oxide, methanol. After extraction, the liquid phase may be concentrated and dried by evaporation or freeze drying. Two or more steps of concentration may be combined. Another method of extraction is by soaking fresh cut or dried plants parts in water and their subjecting the same to steam distillation. The distillate is then concentrated.
A preferred composition may contain 15 mg to 80 mg of Bacopa monnieri, 15 to 80 mg of Embilca officinahs, 15 to 80 mg of Withania somnifera, (Group A) and 5 mg to 30 mg of Piper longum, 5 to 30 mg of Piper nigrum, 5 to 30 mg of Zingiber officinalis, 5 to 30 mg of Foeniculum vulgare and 5 to 80 mg of Alpinia galanga.
A most preferred combination may contain 30 to 50 mg of group A plants and 7 to 20 mg of Zingiber officinahs. Piper longum, Piper nigrum, 10-30 mg of Foeniculum vulgare and 20 to 40 mg of Alpinia galanga under group B.

The following non-limiting example shall serve to describe efficacy of the invention.
Poly herbal liquid, so formulated, as per the example 1, has been tested for its pharmacological efficacy in terms of body weight gain, food consumption, appetite stimulation (bile secretion) and memory enhancement.
Body weight gain and food consumption studies in wistar albino rats Poly herbal formulation was administered orally, at a dose of 28.08 mg per 200 g rat for 28 days, to 6 wistar albino rats and a control untreated group of 6 rats has been included in the study for comparison The data is presented below.
Poly herbal formulation treated group had shown a remarkable and statistically
significant (p from
The above data.
Similarly, statistically significant increase (p
Appetite stimulant studies
As the bile secretion is an important indicator of appetite, the poly herbal formulation has also been tested for its appetite stimulant activity in mice, at a dose of 4.056 mg/20 g mice, for 7 days, using bile secretion method. Results as given below indicated that the weight of the bile was significantly higher in the group treated with poly herbal formulation as compared to control group. Animals were fasted for 18 hours with free access to water, before starting the treatment. Animals were sacrificed at the respective intervals and bile content was estimated, as given below
Evaluation on memory enhancement
Memory enhancement effect of the poly herbal composition has been evaluated in Wistar albino rats at a dose of 28.08 mg/200g rat, by assessing the leaming behavior of animals before and after 7 days of treatment, using Radial Arm-maze method and passive avoidance method. In Radial arm method, poly herbal composition significantly (p
Passive avoidance method
In this method, time taken for each animal to move from bright to dark compartment has been evaluated (Transfer latency time, TLT). An increase in the TLT in subsequent trials is an indicator of improved cognitive ability. Here too, there has been a treatment group and a control group. The results indicated that Poly herbal composition significantly increases TLT values in 3rd trial compared to first trial, which is significantly higher compared to that of the control values.
The results of the radial arm maze method and passive avoidance method indicate that the poly herbal composition remarkably enhanced the cognition and improvement in the retention of learned passive avoidance memory respectively.
