The present invention relates to a novel synergistic herbal composition for the treatment of gastric ulcer. The present invention also relates to a method for the preparation of the composition. The present invention further relates to a process for the treatment of gastric ulcer using the composition.
Various theories have been proposed with respect to a cause of ulcer in human. In particular, it has been elucidated that stress, taking of non-steroidal anti-inflammatory drugs for curing rheumatic diseases, and the like are closely related to ulcer formation, mainly due to relatively excess gastric or duodenal acid secretion. Accordingly it is important to suppress the acid secretion in order to prevent ulcer formation and to cure it.
On the other hand it has been considered that Helicobacter pylori, which is a rod normally existing in stomach, generates ammonia due to its strong urease activity, thereby inducing ulcer. Since, it persistently lives within mucus and mucosa, it becomes the greatest cause for recurrence of ulcer. Accordingly, it has been considered that the recurrence of ulcer can be prevented, if this bacterium is sterilized.

Experimental Protocol:
Invivo Experiments:
The Applicants have carried out several experiments under different induced ulcer conditions and the effect of the herbal composition were studied and are tabulated herebelow. The effect of the herbal composition has been compared with respect to a known anti-ulcer drug “Omeprazole”.
Method: Adult rats of either sex, weighing 150-175 Gms were fasted for 24 hours with free access to water. The test drugs were administered 45 minutes before immobilizing the animals. The rats were immobilized in the restraint cage at 4° C. in BOD incubator for 2 hrs and were sacrificed immediately after the restraint period. (According to the method of Senay and Levine 1967). The abdomen was cut opened; stomach was taken out and incised along the greater curvature to observe the gastric lesions with the help of Magnascope (5× magnification).
The following arbitrary scoring system was used to grade the severity and intensity of the lesions.
The severity of ulcers is expressed in terms of ulcer index, which is the mean score of gastric lesions of all the rats in a group which is defined as:
The percentage protection is calculated as follows:
The effect of the Herbal Composition of the present invention hereafter referred to as “HF2” against Cold Restraint Ulcer Model (CRU) is given in Table 1. The effect of the standard drug “Omeprazole” is also given in Table 1.
Inference: Omeprazole showed 54.03% protection where as the composition HF2 showed 62.90%, protection against gastric ulcer. Thus it is clear that the composition HF2 provides significantly better protection against cold restraint ulcer model as compared to Omeprazole.
Method: Gastric ulceration was induced by aspirin according to the method of Djahanguiri (1969). Aspirin (150 mg/Kg.) was administered per orally as a suspension in gum-acacia and the animal was sacrificed 5 hr. after the aspirin treatment and the ulcer index with protection index were calculated. The results of the experiment is tabulated in Table 2.
The effect of the herbal composition HF2 and the standard drug “Omeprazole” against aspirin induced gastric ulcer is given in Table 2.
Inference: Both Omeprazole and the composition M showed equal protection (39.41% protection) against aspirin induced ulcer model.
Method: Adult rats of either sex were taken; weighing 150-175 grams were fasted for 24 hours with flee access to water. The test drugs were administered (p.o.) 45 minutes before alcohol administration. 1 ml of chilled absolute alcohol was administered (p.o.) to the rats (According to Wittetal)3. Immediately after 1 hour, the animals were anesthetized, abdomen was cut opened stomach was taken out and incised along the greater curvature to observe the gastric lesions. The ulcers are examined under the 5× magnification with the help of magnascope. Absolute ethanol lesions appears as blackish lesions grouped in patches of varying size, usually parallel to the major axis of the stomach. The lengths of the lesions are measured and summated to give a total lesion score, then calculated and expressed in percentage.
The effect of the herbal composition “HF2” and the standard drug “Omeprazole” against alcohol induced gastric ulcer in rats is given in Table 3.
Inference: The composition of the present invention showed significant protection against this model also. The protection provided by the composition of the present invention is better than Omeprazole.
Method: Animals were fasted for 24 hours with access to water. The drug was given orally 1 hour prior to the histamine administration. Histamine was administered in a dose of 0.25 mg/Kg, i.m. at 30 minutes interval-for 7 times and it induced 100% duodenal ulceration in guinea pig (According to the method of Watt and Eagleton 1964)4. The animals were sacrificed after half an hour of last injection under ether anesthesia. The stomach along with duodenum was removed washed thoroughly and examined for the lesions and ulcer index with protection index was calculated. The results of the experiment are tabulated in Table 4. The effect of the herbal composition “HF2” and the standard drug “Omeprazole” against Histamine induced ulcer model is given in Table 4.
Inference: In this model, Omeprazole showed 70.79% protection whereas the composition HF2 showed 68.3% protection. In comparison, the composition HF2 provides more or less equal protection.
Method: Animals were fasted for 24 hours in the raised mesh bottom cages to prevent coprophagia and were allowed free access to water. The control group of rats was feed with the vehicle and the experimental groups with their respective drugs 45 minutes prior to the ligation. The animal was anesthetized, abdomen was cut opened sunder xiphoid process, and the pyloric portion of the stomach was slightly lifted and ligated avoiding any damage to the adjacent blood vessels (According to the method of Shay et al. 1945). The animals were stitched and kept for 4 hours with free access to water. After 4 hours the animals were sacrificed under ether anesthesia and the stomach was dissected out incised along the greater curvature. The stomach was washed thoroughly and the ulcer index was scored as per in other ulcer models. The results of the experiment are tabulated in Table 5.
The effect of the herbal composition “HF2” and the standard drug “Omeprazole” against Pyloric ligation induced ulcer model is given in Table 5.
Inference: The composition of the present invention showed better protection than Omeprazole in the pyloric ligation induced ulcer model.
Method: A piece of 2-3 cm of the terminal ileum of a freshly killed Guinea pig was suspended in an organ bath containing Tyrode solution at 34° C. and bubbled with fresh air. Contraction was induced by submaximal contraction of acetylcholine chloride (1 [ig/mL) and Histamine (1 ng/mL) and it was recorded on a kymograph (According to the method of Patnaik 1992). The composition HF2 (up to 250 ng/mL) did not exert any significant influence on isolated tissue preparation for anticholinergic (acetylcholine-induced contraction of Guinea-pig ileum) and Fk-anti-histaminic (Histamine induced contraction of Guinea-pig ileum) activity.
For the purpose of conducting animal experiment all the herbs are washed dried and pulverised. All the herbs are taken in the proportion as shown in Table 6. The whole mixture is blended well and used for administering.
The components and their proportions of the standard herbal composition according to one embodiment of the present invention are listed in Table 6. The part of the herb which is used is also mentioned. The placebo preparation is designed to taste, smell and look like an Ayurvedic herbal composition.
In order to conduct a study on the synergistic effect, the herbal composition HF2 was taken and each component was removed and the effect of the resultant composition against cold restrained gastric ulcer model was studied. The results of the experiment thus conducted is tabulated in Table 8. It was concluded from the above experiments that the batch prepared by the removal of Emblica ribes has shown very good protection.
