INTRODUCTION
Herbal medicines are used as a health care tool in various countries. All the developing countries are fully dependant on herbal remedies1. Bibhitaki, also known as Baheda in Hindi2, is one among three fruits of Triphala. Triphala is one of the Ayurvedic formulaions which may have antifungal, antibacterial, laxative, hypolipidimic, antidiabetic and immunomodulatory activities3. Triphala or its constituents used against infectious microorganisms also4. Bibhitaki means the fruit that takes away the fear of disease.Its botanical name is Terminaliabelerica belongs to family Combretaceae5. A plant with active medicinal properties or constituents are used to treat disease in the traditional systems like Ayurveda, Siddha and Unani6,7. Herbal medicines are prepared from different plant materials such as leaves, stems, roots, bark etc. They mainly contain biologically active ingredients and are used primarily for treating mild or chronic ailments8. Ayurvedic remedy is commonly used in India. Maximum the Ayurvedic formulations are good in cold, cough, dysentery and increases appetite. Baheda fruit may contain chemicals such as tannins,elegiac acid, beta cetosterol 9. A ripened plant of Baheda used as a purgative. All medicinal plants are used to cure all disease which may affects the Human being10.
According to Ayurvedic principles this fruit(T.belerica) may increase the dryness of the tissue which may leads to ingest11. Bibhitaki primarily supports formation of three body tissue i.e. nutrients plasma (rasadhatu), muscle(mamsadhatu), bone(asthidhatu). It is a powerful medicine for a vaiety of lung conditions, in which bronchitis and asthma are involved. Plants produce a wide array of bioactive principles amd contains a rich source of medicines. It grows all over India12. In India, 45,000 plant species have been identified and out of around 15 to 20 thousands plants are found which may have good medicinal value13,14.

TRADITIONAL USES
In Ayurveda, the drug T. belerica is identified as an expectorant. It is an integral part of Ayurvedic laxative35, astringent, anthelmic, and antipyretic which is useful in hepatitis, bronchitis, piles, coughs, eye disease such as myopia, corneal opacity etc. hoarseness of voice, it is also used as hair tonics36. It has lithotriptic , rejuvenative and antibacterial properties. The fruits are used in astringents, digestive, aperients, stypic, narcotic, Unripe fruit is a mild laxative and ripe fruit is an astringent37.Decoction of the fruit is used for cough. Flowers are greenish-yellow, borne in axillary, and having offensive odor. Stem are straight, frequently buttressed when large24. The bark is midly diuretic acid and also useful in anaemia and lucoderma. The palnt may contain seed oil which is used in rheumatism. Maximum the triterpenoids present in the fruits possess antimicrobial activity. T. belerica also promotes hair growth38. The fruit is chewable and curable for cough, cold etc. Baheda as also useful for diabetes, urinary disorder. The oil of Kernel may used in mice as purgatives39. Vibhitaki is used primarily to lower kapha- related diseases and respiratory disorders. It can expel stones or other types may assemble in digestive, urinary, and respiratory tracts40. One third of classic formulations Triphala, known as cleanser and nourisher of kalphadosha. Useful for maintainance of balancing the body including the body fluids. It is also used in treating disorders relating to the manipura chakra relating to functions of abdominal nervous system41.
Recent research shows that bibhitaki reduces levels of lipids; fatty acids through the body ad specifically lower the lipid levels in the liver and heart. This shows a strong action in preventing heart, liver and fat congestion42. As a daily rejuvenating an preventive supplement bibhitaki is good, especially for kapha body types43.
Digestion: It is known as the best tonics for the digestive systems, Bibhitaki juice keeps the system clean and resolves the digestive functions. Respiratory System: Problems related to respiratory such as asthma, bronchitis and phlegm can be prevented by Bibhitaki44. Cuts and Wounds: Applying Bibhitaki paste on cuts and wounds can be prevented excessive bleeding. For Dry and inflamed eyes: Mainly the physician recommends ghee processed with Bibhitaki, amlaand haritaki in treatment of dry and inflamed eyes45. For cough, cold, and bad throat: The small bits of pulp of dry bibhitakifruit has to be fried in pure ghee. These bits are chewed slowly to get relief in cold, cough and bad throat. Diabetes: Bibhitaki can be effectively used in diabetes. Then it normalizes kapha and medhas, which are main cause of diabetes46.Irritable bowel syndrome: The dry fruit powder of this fruit help to reduce increased motility of Intestines in IBS. It also helps to reduce the inflammation of walls of intestine47.
Precaution: This herb should not be used in excess and pregnant women have to avoid consuming Bibhitaki48,49.
PHARMACOLOGICAL ACTIVITIES
Immunomodulatory Activity
A chemical agent that modifies the immune response or the functioning of the immune system is referred as immunomodulator. This is commonly known that macrophages gives role in different mechanism against the infection of host and used in destroying the tumor cells. T.belerica fruit extract possess immunomodulatory activity which is proved by phagocytic and lymphocyte proliferation activity of fruit methanolic extract on the mouse. Where methanolic extract has been reported to stimulates the production of superoxide anions and acid phosphatase then it may promotes the macrophage phagocytosis. T.belerica extract with cocanavalin A and pokeweek mitogen caused suppressant activity. Whereas acetone extracts of T.belerica has been shown to increase the B- and T-cells proliferation along with increased IL-10 secretion whereas it reduced the production of IFN-a and IL-250.
β-Lactamase inhibitor Activity
The β lactamase inhibitor activity of 68 extracts from Indian herbs and spices was surveyed. Most promising results of the β lactamase inhibitor activity invivo and invitro were achieved from the herbal extracts of Bibhitaki. Ginger (Zingiberofficinales), Brahmi (Bacopamonnieri), Garlic (Allium sativum), Gurmar( Gymnemasylvestre), Satavar ( Asparagus racemosus), peels and seeds against Staphylococcus aureus as the test organism51.
Antibiofilm Activity
The ethanolic extract of a plant Baheda was tested for its antimicrobial activity against the oral plaque forming bacteria i.e. Streptococcus mutans. Used in a inhibition of formation of biofilm. Mostly investigates that the plant extract may showed activity against Streptococcus mutans. The extract also prevents in the formation of biofilm with the help of bacteria. The study explains the benefits of this herbal preparation which inhibits the biofilm formation by streptococci, oral pathogens52.
Antiulcer Activity
The antiulcer activity of ethanolic extract of Baheda fruits an ETB was searched out in pylorus ligation and ethanol also may help to produce ulcer models in r rats. In both models the common parameter determined was ulcer index. ETB at doses of 250, 500 mg/kg orally produced significant inhibition of the gastric lesions induced by Pylorus ligation induced ulcer & Ethanol induced gastric ulcer. The extract (250 mg/kg & 500 mg/kg) showed significant reduction in free acidity and ulcer index as compared to control53.
In Vitro Glucomylase Activity
T.belerica fruit rind powder was assessed for its antimicrobial activity by using Chloroform-Ethyl Acetate fractions.Maximum zone of inhibition was observed in both fractions.The fractionized compound Epigallocatechingallate showed significant antimicrobial activity against E.coli , B subtilis and S.Aureus54.
Wound healing actvity
Wound healing is a complex phenomenon which includes a number of processes such as migration and proliferation of both epithelial and connective tissues, formation of extracellular matrix proteins, alteration of connective tissue, parenchymal components, collagen synthesis. The wound healing potential of extract has been reported in rabbit model. Extract paste (500mg/animal) was applied to skin incision from the dorsal area of rabbit. Significant increase in the levels of hydroxyproline, DNA and uronic acid contents and improvement on maturation, wound contraction and epithelialization was observed between 4-12 days. The study suggested that the herbal paste from T.chebula and T. belerica enhanced fibroblast function, improved production of glycosaminoglycan and deposition of collagen which is required for wound healing and may be useful in wound healing process55.
Analgesic Activity
T.belerica extracts also have antisecretory and analgesic activities. The extract have dose range of 300-1000mg/kg inhibited the castor oil-induced intestinal fluid secretion in mice. The extracts also dose dependently (50-100mg/kg) where it may reduce the numbers of acetic acid in mice. These are the results which indicate that TB exhibit antisecretory and antnociceptiveeffects, hence justifying its medicinal use in diarrhea and pain56.
Antidiarrhoeal Activity
By using castor oil the Anti diarrhoeal activity was performed to induced diahrroea. Mainly PGE2 induced entero pooling and gastrointestinal motility test. Aqueous and ethalonic extract of fruit pulp of TB at the doses of 334mg/kg, 200 mg/kg were used . By this in the comparison of percentage initiate on these models showed that the extracts have anti secretory effect .An activity of reproductive system in rats. It was determined that Adult male rats were administered with 10mg/100g body weight of benzene and ethanol extracts of Terminaliabelerica barks orally for 50 days. Repeated administration of TB bark extract results that it decreased weight of the reproductive ducts in male rats48.
Antidiabetic Activity
Hexane, Ethylacetate and Methalonic extracts of TB fruits at the different doses of 200,300 and 400mg/kg,p.o for 60 days to Streptozotocin induced diabetic rats by increasing the plasma insulin, C-peptide and glucose tolerance levels, serum total protein, body weight. By adding of plant extracts it may decreased the serum levels of total cholesterol, triglycerides, urea, uric acid and creatinine in diabetic rats57.
The reduction of glucose level and Oxidant enzymes such as Superoxide dismutase, glutathione reductase and acatalase were observed in blood and liver. Oxidative stress arise from an imbalance in the formation and metabolisms of reactive oxygen species(ROS). Antioxidants are the molecules that inhibit or reduce free radical reactions and finally prevent cellular damage. Both forms of antioxidants (enzymatic and non enzymatic) are present in the intracellular and extracellular environments59.
Antipyretic Activity
The antipyretic activity of ethanolic and aqueous extract of Baheda fruits (200 mg/kg) was studied in brewer’s yeast-induced fever models in mice and rats. Both of extracts showed that inhibition of elevated body temperature when compared to corresponding control58.
Acute and Sub-Acute Toxicities
The acute and sub-acute studies were conducted as per the guidelines of OECD. Single oral administration of the ethanolic extracts of T. belerica at a dose of 5,000 mg/kg did not produce any toxicity. In sub-acute toxicity, repeated administration of 1,000 mg/kg of T. belerica in 14 days which may not cause change in various effects of behaviours, mortality test, gaining weight, blood chemistry initiatives. The results of examinations showed normal appearance of the internal organs when compared to those of the control group49.
Antispasmodic and Bronchiodilatory Activity
In Vitro Cellular Toxicity
In present study, ether, chloroform, acetone, alcoholic extract, and of Baheda fruit used for screening. When compared with other extracts both alcoholic and aqueous extracts of TB showed anti-salmonella activity. There was no cytotoxicity was observed in invitro cellular toxicity study60.
In Vitro Immune Response
In vitro Phagocytic activity and lymphocyte proliferation assay were carried out methanolic extract of on the mouse immune system . In evaluations, incentive of macrophage phagocytosis and activation of phytohemagglutinin were observed. Finally, the authors concluded that the methanolic extract of T.belerica affected on the mouse immune system, specifically cellular and humoral immune response in vitro5.
Anti-salmonella Activity
Antihypertensive Activity
The effect of T. belerica in hypertension. After administration of T. belerica, they observed that fall in the arterial BP of rats under anaesthesia. In isolated guinea pig atria, inhibition of force and rate of atrial contractions noted. In thoracic aorta of rabbit, relief observed after the administration of contractions which was produced by giving phenylephrine 56.
Hepatoprotective Activity
The protective effects of TB fruit extract and its active constituents against CCl4 in toxicity. Treatment with extract (50,100 and 200mg/kg, p.o.) showed dose dependent recovery in parameters such as SGOT, SGPT and lipid peroxidase, glutathione but the affect of Galli acid is more reliable61. The liver is a vital organ of vertebrates and some other animals.62. Hepatotoxicity refers to inability of liver to detoxify the toxic compounds. In this one of the most sensitive and dramatic indicators of hepatocyte injury is the release of intracellular enzymes, such as transaminases and serum alkaline phosphatase in the circulation during hepatic abnormalities. Pharmacological activities of the enzymes are useful of cellular drainage and loss of morality of cell membrane in liver63. Methanolic extract of T. belerica fruit has both reducing power as well as iron chelating activity and by tjis it may reduce the toxic level of iron in iron overload mice and hence protects liver from oxidative stress and fibrosis. Its administration lowered serum enzyme and serum ferritin levels, which act as a indicators of severe iron overload64.
Antimicrobial Activity
T.belerica has shown potent action against infectious agents in vitro. Fruit extracts contains phenol, tannins,alkaloid, and flavanoids. Alkaloids are mainly responsible for inhibiting the microorganisms by impairing the enzymes involved in energy productions, interfering with the integrity of cell membrane and structural component synthesis. In the fruit extract of T.belerica have tannins may be useful in preventing the formation of microorganisms. T.belerica extracts inhibit the activity of this enzyme when S.aureas grown in the presence of T. belerica extract. The aqueous fruit extract has shown activity against numerous pathogenic bacteria viz. Eschrechiacoli, Pseudomonas aeruginosa, etc. T. belerica also showed antibacterial activity against many Gram positive and Gram negative bacteria including Corynebacteriumrubrum, Staphylococcus epidermidis, K. pneumonie etc. However, studies have demonstrated that antibacterial activity was associated with the polar extracts65.
Anti-mutagenic Activity
Water, acetone, and alcoholic extracts of Terminiliabelerica were found for their antimutagenic activity by using the various assay on of them is to be Ames Salmonella asay. Acetone extract exhibited variable inhibitory activity of 65.6 % and 69.7% with 4-O-nitropenylenediamine and sodium azide , and 81.4% with 2-aminofluorene, in the preincubation mode of experimentation. Inhibition with choloroform and water extracts was rather insignificant66.
Anti-urolithiatic Activity
Antirolithiatic activity of fruits of the Terminilia belerica on ethylene glycol induced renal caluculi in albino rats. In which renal stone was induced in rats around 0.75% ethylene glycol by drinking water for 25 days . After that a test dose are given with alcoholic extract of plant at different doses forms i.e. 100,200, 400mg/kg b.w.once a day. Till 15-28th day. Where cystosone(750mg/kg) used as standard drug. The effect of plant on various parameters in urine also in serum was evaluated. The results demonstrated that Met B (400mg/kg) reduced the ethylene glycol induced disturbance in different parameters in urine or serum67.
Nephrotoxic Effects
The rats were devided into 5 groups where 1st groups served as a control and injected with normal saline, 2nd group injected with Gentamicin or Silymarin 100mg/kg p.o. , 4th or 5th group were injected with Terminilia belerica ethanolic or aqueous extracts plus gentamicin for 15 days . 2nd group showed early kidney dysfunction as serum urea, uric acid and creatnine which may increases. It indicates that GM induced nephrotoxicity. Administration of T. belerica plus gentamicin may protect kidney tissue against nephrotoxic effects68.
Angiogenesis Activity
The angiogenic potential of T. belerica by invivo mice sponge implantation assay. Here are gelatin sponge with or without ethanolic extract of T. belerica leaf were subcutaneously injected into albino mice and after 14 days the implanted sponges were excised and that section evaluate the presence of sponge. In which EETB may produce various blood vessels in gels which can sponges individually. Another vessels were filled in with red blood corpusules which may shows the formation of a fibro vascular inside the sponges and blood may circulate in another formed of vessels by angiogenesis produced by EETB . Thus ethanolic extract of the plant leaf inhibit the profound angiogenic activity invivo69.
Antithrombolytic and Thrombolytic Activity
A myocardial and cerebral infraction is serious consequences of the thrombus formed in blood vessels. A thrombus formed in circulatory system with the failure of haemostasis. Thrombolytic agents are used to remove the previous blood clots from blood vessels70. used an invitro model to check the antithromobolytic effect of alcoholic and aqeuous extract of T. belerica fruits. Striptokinase is used as a positive contol. The study showed that extract delayed the clot formation71.
Mastitis Activity
Mastitis is most affecting disease of diary industries.This study was to evaluate the antibacterial effects of hot aqueous extraction(HAE) of the fruits of Terminilia belerica on field isolates of mastitis. HAE of the fruits of T.belerica make mixture with another selected plants and used for their synergistic/antagonistic effect.The antibacterial potential was determined by disc diffusion method. The inhibition zone decreases after 24hrs. which may show effect as bacteriostatic rather than bacteriocidal.After all this is justified that the use of Triphala as a compound of Bahera treat the clinical/subclinical mastitis 72.
Toxicity Study and Anti-inflammatory Activity
Terminalia belerica extract administered at different doses such as 2000-1000mg/kg in acute or subacute toxicities studies. Antiinflammatory activities of T.belerica extract evaluated in carrageenan induced paw edema model. For the activity, the animals were divided into 5 gps. They have different doses such as Group-1 control, Group-2 Indomethacin 3mg/kg, Group-3 TBE 100 mg/kg, Group-4 TBE 200mg/kg, Group- 5 TBE 400mg/kg. Then the results show that the mortality and signs are non observeable in acute and repeated toxicity studies after administration of TBE dose of 2000mg/kg. Antiinflammatoy activity showed in carrageenan induced paw edema model 1,3and 5 h.A inhibition of paw as compared to control gp. was observed at different doses 100,200 and 400mg/kg at 1,3 and 5h. and comparable efficacy has be shown of indomethacin at 200mg/kg73.
Antibacterial Activity
The antimicrobial activity was evaluated by using agar well diffusion method against the Gram –ve or Gram +ve bacteria such as Staphylococcus aureus, Staphylococcus epidermidis, Bacillus aureus, Pseudomonas aeruginosa, Salmonella, Escherichia coli and Azotobacter etc. These bacterias are isolates using methanol, ethanol, acetone, chloroform and leaf extract of T. belerica. All by this it was observed that the ethanolic extracts gives the good activity against the tested bacterial isolates, as comparatively methanol, chloroform, or aqeuous extract also. Hence, this study states that the Triphala and its constituents may reveal antibacterial activity against the human pathogenic bacteria74.
Antioxidant Activity
Due to imbalancing in generation and metabolism of ROS an oxidative stress has been arised, when the more ROS produced than that is metabolized75. The supplements used as antioxidants are help to reduce oxidative agents76. The present study evaluated the antioxidant activity of T.belerica fruits. The study was to evaluate the antioxidant study, total phenolics,flavanoids content of aqeuos(AETB)and ethanolic extract(EETB) of fruits of T.belerica77 . The antixidant activity was investegated by DPPH(1,1-diphenyl-1,2-picryl hydrazyl), ABTS(2,2-Azino-bis 3-ethyl benothiazoline-6 sulphonic acid diammonium salt, superoxide,nitric oxide,reducing power and TAC(Total antioxidant capacity)78. The higher antioxidant activity has been shown by AETB as compare to EETB in nitric oxide,superoxide etc. In antioxidant activity the reducing power increases in dose dependent manner which may showing higher absorbance at 700nm for AETB that is 0.95+-0.03 as compare to EETB which is 0.43+-0.01. The total phenolic and flavanoids amount were also determined. The antioxidant activity of T. belerica fruit were contribute by TPC and TFC75.
Anticancer Activity
In Ayurveda the main constituent of T.belerica is Triphala which may have the cytotoxic effects against different cancer cells,breast cancer cell, pancreatic cancer cell, prostate cancer cell. The acetone extract of T.belerica exhibited antimutagenic potency using microsome assay. These extracts are having different inhibitory activity 65.6% and 69.7% with 4-O-nitrophenylenediamine and sodium azide also66.
Anti-obesity Activity
The study investigated the effect of ethanolic extract of fruits of Terminalia belerica on Atherogenic diet which may induced obesity in rats. The rats were devided into 4 groups i.e. group1-control rat, group2- obesity control, group3- obesity +500mg/kg fruit body weight of extract of T. belerica, group4- obesity+10mg/kg body weight of sibutramine. Body temperature, weight gain, feed and water intake, BMI and lipid profile were measured. The continuous administration of ethanolic extract of T. belerica at the dose of 500mg/kg had significant effect in the parameters similar to drug of Sibutramine. The ethanolic extract of Terminalia belerica is useful in the treatment of obesity79.
CONCLUSION
The extensive survey of literature revealed that Terminaliabelerica, it is an important medicinal plant with various pharmacological spectrum. Further study of ayurvedic human uses of herbs, is found as an useful for the locate advanced medicaments. In which one of the plant ofTerminaliabelerica is widely used in Ayurveda. Crude extracts of various parts of Terminaliabelerica plant have been found to contain constituents such as Glucoside, Gallo-tannic acid, colouring matter, resins, ellagic acid, gallic acid, lignans, termilignan, ethyl gallate, phenyllemblin Tannins, mannitol, fructose, rhammnose. These compounds are responsible for the pharmacological activities i.e. antimicrobial, antioxidant,antisalmonella, hepatoprotective, antispasmodic, and anticancer activities. Further the plant is used in the treatment of gastric ulcer, constipation, piles. Hence, this plant provides a significant role in the prevention and treatment of disease. Further evaluation needs to be carried out in order to explore the concealed areas and their practicals clinical applications, which can used for the welfare of the mankind.
