A large number of people suffer from gall stone worldwide and this problem is now being increased significantly due to the malnutrition, changes in living style, lack of exercise and conditions i.e. industrialization. Medicinal plants are used from centuries due to their cultural acceptability, efficacy, safety and fewer side effects as compared to modern synthetic medicines
Gallstone is a worldwide problem. Its pervasiveness gives off an impression of being higher in Western world (>10%) than in Asian countries (3–10%). Female sex, older age, hyperlipidemia, higher body mass index (BMI), diabetes mellitus and alcohol consumption have been accounted for as danger factors for gallstone problem. Cholelithiasis (gallstone formation) is generally found in adults as compared to children. The frequency of gall stones among children is 1.9%. About 10 - 20% adult population of Western countries suffers from gall stones [1].
The gallbladder is a sac situated under the liver. It stores and concentrates the bile, produced in the liver. Bile acids play an important role in the assimilation of fats and is delivered from the gallbladder into the upper small digestive tract (duodenum) in response to food, especially fats. Development of stones inside the gall bladder is known as cholelithiasis. In this condition, hard stones of cholesterol or bile pigments are formed in the gallbladder. If these stones are found in the common bile duct, the condition is known as choledocholithiasis. Most of the stones are composed of cholesterol [2].
Bile is composed of bile salts, cholesterol and lecithin. It is present in a solution form by a delicate harmony. The proportion between bile salts and cholesterol is very important. In bile, cholesterol is in equilibrium with bile salts and with phosphatidylcholine. When the cholesterol becomes too concentrated in the bile then it saturates the bile acids and start to form crystals. As a result, a sludge is formed which contains cholesterol, calcium salts, mucin, and bilirubin and ultimately stones are developed [3].
It is reported that the gallbladder smooth muscle (GBSM) bundles and their associated contractions are responsible to form gallbladder tone. The gallbladder performed a motor function, with 20-30% emptying at 1-2 hrs. intervals during the fasting state while 70–80% emptying after stimulation by cholecystokinin (CCK) when a diet is taken. The gallbladder contraction and relaxation is very important in driving the flow of bile salts in enterohepatic circulation and facilitate the absorption of lipids and fat-soluble vitamins. It is observed that changes occur in gallbladder smooth muscles in the gallbladder harboring lithogenic bile prior to inflammation and stone formation. Many factors are responsible in the pathogenesis of gallstone disease in which, gallbladder hypomotility and the resultant prolonged stasis of lithogenic bile are the most important. This malfunction is a very early event in the development of Gallstone disease, which occurs only in a few days after the onset of the lithogenic diet and becomes worse as the ailment progresses from microlithiasis to gallstones. Muscle contractility is diminished in gallbladders from patients with cholesterol stones. Impaired emptying of gallbladder may results in prolonged stasis of lithogenic bile in the gallbladder, which allows more time and a permissive environment for cholesterol crystallization and aggregation of that cholesterol into macroscopic gallstones.
A longer stay of bile in the gallbladder may lead to its hyperconcentration by gallbladder epithelial cells (GBECs). Increase in secretion of pro-nucleating mucins by GBECs is considered as an important factor responsible for gallstone formation. The gel-forming mucins made favorable environment for gallstone formation as it accelerate the nucleation of cholesterol monohydrate crystals from supersaturated bile [4]. There are three important factors responsible for cholesterol gallstone formation, bile composition (in particular cholesterol supersaturation and hydrophobic bile salts), factors promoting cholesterol crystallization (e.g. certain biliary proteins) and impaired gall bladder motility. In cholesterol gallstone disease, elevated biliary concentrations of cholesterol and hydrophobic bile salts are associated with biliary stasis. The main features of gallstone problems are biliary cholesterol elevation, cholesterol stones, decreased gallbladder contractility and cholecystitis [5]. Improving gallbladder motility with a prokinetic agent leads to a significant reduction in cholesterol crystallization. Gallbladder motility is promoted or increase or stimulated by CCK (Cholecystokinin) release, CCK receptor stimulation and decrease inflammation [6]. Medicinal plants having hepatobiliary effect are important therapeutic agents for cholestasis. These are called as choleretics (increasing bile production) and cholagogues (promoting the flow of bile from the liver and gall bladder into the intestines) [7].
