An ethnobotanical survey and pharmacological evaluation of medicinal plants used by the Garo tribal community living in Netrakona district, Bangladesh.


Throughout history plants have been used by human beings for medicinal purposes and even in modern times have formed the basis of many pharmaceuticals in use (Schmidt, et al, 2008). Plants produce a vast array of secondary metabolites as defense against environmental stress or other factors like pest attacks, wounds, and injuries. The complex secondary metabolites produced by plants have found various therapeutic uses in medicine from time immemorial. The early history of modern medicine contains descriptions of plant-derived phytochemicals, many of which are still in use. Some examples are the discovery of cardiotonics in foxglove, salicylic acid in willow bark, and morphine in poppies (Rishton, 2008). Various terpenoid compounds, which are synthesized in plants as secondary metabolites are proving their potential in modern scientific studies against inflammatory diseases and cancer (Salminen, 2008). A recent review has shown that approximately 25% of modern medications have been plant derived, while 75% of new drugs against infectious diseases that have arrived between 1981 and 2002 originated from natural sources (Bedoya, et al, 2009). Herbs and spices have been used from ancient times not only to increase palatability in foods but also for their health beneficial effects. Scientific studies have demonstrated the anti-oxidative potential of many herbs and spices, which is important since oxidative damages have been implicated in major diseases like atherosclerosis, arthritis, and diabetes. The cholesterol-lowering effect of garlic, use of ginger in ameliorating arthritic knee pain, and the effect of several herbal supplements on psychological and cognitive function has been reviewed by Tapsell et al (2006). Despite the progresses in modern medicine, it has been reported that more than 70% of the developing world's population still depends on complementary and alternative systems of medicine, otherwise known as traditional medicine (Shaikh, 2005).

The advent of allopathic medicine shifted scientific and general population interest from traditional medicinal preparations. However, in recent years, a major paradigm shift has taken place. Interest has refocused on traditional medicine, because of the high cost of modern drugs, time and expenditure that is necessary to bring a drug to market after appropriate clinical trials, serious side-effects of a number of modern drugs, and drug-resistance developing in both microorganisms and parasites. As a result, scientists are now taking an active interest in traditional medicinal preparations of indigenous peoples, which mostly are plantbased. One example is the renewed interest in anti-inflammatory traditional medications. Inflammatory diseases are common in the aging society of developed and developing countries; yet, the drugs used to combat inflammatory diseases like rheumatoid arthritis often have serious side-effects. Several leads from plant sources, like curcumin, resveratrol, baicalein, boswellic acid, betulinic acid, ursolic acid, and oleanolic acid are now studied as possible drugs for the future against inflammatory diseases (Gautam, 2009). Edible plant extracts have shown promising anti-tumorigenic activity (Amara, et al, 2008). Anti-cancer agents from plant sources currently being used or undergoing clinical trials include vinblastine, vincristine, nevelbine, etoposide, teniposide, taxol, taxotere, topotecan, and irinotecan (Wang, 1998). A large number of traditional medicinal preparations used in various countries of the world have shown promise as treatment for herpes virus infections, which cannot be completely cured by the available anti-herpes drugs like nucleoside analogs (Chattopadhyay, 2008). The various ailments for which searches are going on in plants for newer drugs are too numerous to mention; to cite just a few examples, new plant-derived compounds are being searched for treatment of malaria because of the increasing resistance of Plasmodium falciparum against currently available anti-malarial drugs (Batista, et al, 2009; Kihampa, et al, 2009), searches for anti-fungal, molluscicidal and larvicidal compounds in African medicinal plants has been reviewed by Marston et al (1993), anti-leishmanial activity in Israeli plants has been reviewed by El-On et al (2009), and anti-trypanosomal and cytotoxic activities of pyrrolizidine alkaloid-producing plants of Ethiopia has been reported by Nibret et al (2009).

Since indigenous peoples have a long history and expertise in the use of medicinal plants, it is important that their plant usage be documented as the basis for development of lead compounds before this knowledge is lost due to the influences of modern civilization. Bangladesh has a number of indigenous people or tribes, including the Chakmas, Garos, Santals, Marmas, Oraon, Mrus, Rakhains, Tripuras and others. We have previously conducted ethnobotanical surveys among the Rakhains and Tripura tribes residing in the Chittagong Hill Tracts region, the Santals residing in Rajshahi district, and the Garo tribal community inhabiting the Madhupur forest region (Tangail district) of Bangladesh (Hanif, et al, 2009; Hossan, et al, 2009; Shahidullah, et al, 2009; Mia, et al, 2009). The Garos (once a nomadic tribe of the Bodo group of Mongoloids) are a large tribal community spread among the north-central districts of the country like Mymensingh, Netrakona, Gazipur, Sherpur and Tangail. A number of Garos have recently adopted Christianity; however, they still basically follow their own religion with its associated customs and rituals. They have their own traditional medicinal practitioners, known as khamals or kamals, who besides practicing medicine, also conducts vows and arranges festivals. The khamals possess considerable expertise on medicinal plants, which is learnt through teachers or "gurus", family members, and trials on patients. This knowledge is usually confined to the family and passed on from generation to generation. Because the Garo communities lack any alphabet and because they are spread-out among the different districts, the traditional uses of medicinal plants for treatment of various ailments differ among the khamals of different districts. The objective of this present study was to conduct an ethnobotanical survey among the khamals of the Garo community living in Netrakona district, Bangladesh to document their medicinal plant usage and to compare their use of medicinal plants with that of the Garo community living in the Madhupur forest region of the country.

2. Materials and methods

2.1. Study area

Netrakona district in Bangladesh is situated roughly between 90[degrees]30-91[degrees]15 E and 24[degrees]35- 25[degrees]15 N. The district is comprised of several sub-districts. The present survey was conducted among the khamals of Garo communities living in the villages of Ranikong, Madhavpur and Bipinganj, all villages being situated within Durgapur sub-district.

2.2. Data collection and sampling techniques

A total of five khamals were interviewed in the present survey. They were all males and named Raja, Xavier, Sentu, Semintas, and Badsha. Among them Xavier has adopted Christianity and regularly goes to a church located between Madhavpur and Bipinganj villages, where he has picked up acquaintances with the church doctor (a modern allopathic doctor). Xavier, however, practices the traditional system of Garo medicine (including diagnosis and treatment of ailments), which he has picked up from his family. Nevertheless, he has picked up a few medical terms like cancer and diabetes from the allopathic doctor. However, his diagnosis and choice of medicinal plants for treatment of the above two diseases did not differ from the other khamals, who diagnose diabetes and cancer, respectively, by the sweetness of urine, and by the presence of symptoms like weakness, loss of appetite, fever, itches that do not heal, or swellings, and which cannot be attributed to any of their known ailments. It needs to be pointed out in this respect, that diabetes is a known ailment of the khamals who refer to it as "chini-rogh", "chini" standing for sugar and "rogh" standing for disease. Cancer is a modern term picked up by the khamals, who do not understand it properly and attributed it to unexplained symptoms as described earlier.

Informed consent was obtained from the healers prior to the survey. The purpose of the survey was explained to them in details and they were told that the survey had no other intentions apart from documentation of their medicinal plant usage. The survey was conducted with the help of a semi-structured questionnaire. Interviews were conducted in the Bangla language, all healers being fluent in the language spoken by over 95% of the Bangladesh population. The local names of the medicinal plants, however, were given in the Habeng language spoken by the Garos and which was found to have similarities to the Bangla language. The basic survey method was that of the guided field-walk method as described by Martin (1995) and Maundu (1995). In this method, the khamals took the interviewers to the areas from where they collected their medicinal plants and gave information as to plant name, plant parts used and ailments treated. All information was cross-checked with the khamals in later evening sessions. Plant specimens were collected and dried on site and brought back to the Bangladesh National Herbarium for identification, where voucher specimens were also deposited.

3. Results and discussion

3.1. Plants and their distribution into families

The result of the present survey shows that the khamals of the Garo community of Netrakona district used 74 plants distributed into 45 families for treatment of various ailments (Table 1). The Fabaceae family contributed the largest number of species (eight). Other families contributing more than one plant per family included the Araceae, Asteraceae, Moraceae, Solanaceae and Verbenaceae families (three plants per family), and the Acanthaceae, Anacardiaceae, Euphorbiaceae, Poaceae, Rutaceae and Zingiberaceae families (two plants per family). Some plants were not obtained from the wild. Among plants cultivated for both home consumption and commercial purposes were Mangifera indica (mango), Areca catechu (betel nut), Borassus flabellifer (sugar palm), Cocos nucifera (coconut), Ananas comosus (pineapple), Carica papaya (papaya), Luffa cylindrica (vegetable sponge), Emblica officinalis (Indian gooseberry), Manihot esculenta (cassava), Cajanus cajan (spotted pigeon pea), Lablab purpureus (hyacinth bean), Tamarindus indica (tamarind), Punica granatum (pomegranate), Moringa oleifera (drumstick tree), Musa sapientum (banana), Psidium guajava (guava), Syzygium cumini (black plum), Averrhoa carambola (star fruit), Piper betle (betel leaf), Ziziphus mauritiana (Indian jujube), Aegle marmelos (wood apple), and Zingiber officinale (ginger).

3.2. Plant parts used and mode of preparation

The various plant parts used included whole plant, leaf, root, stem, flower, seed, bark, gum, fruit, petiole, and rhizome. Of the 107 uses observed in the present survey, leaves formed the part predominantly used (33.6%), followed by whole plant (15.9%), fruits (15.0%) and stems (11.2%). For a number of plants, multiple plant parts from the same plant were used. For instance, the roots of Achyranthes aspera were used to treat snake bite and diabetes, while seeds from the same plant were used for treatment of gonorrhea. A combination of bark and seed of Thevetia peruviana was used to treat mental disorders. The mode of administration was either oral or topical. For oral administration, generally juice was extracted from the plant part following crushing and then taken. However, in the case of Cocos nucifera, juice of the fruit (coconut juice) was directly taken for treatment of diarrhea. The barks and seeds of Syzygium cumini are also directly taken for diabetes, while a combination of leaf and petiole paste of Piper betle is taken as treatment for bronchitis, indigestion, and as antidote to poison. For topical applications, usually a paste of the plant part (e.g. Mikania cordata) or powdered plant part (e.g. bark of Crataeva religiosa) was applied.

3.3. Medical applications

A plant or plant part may be used to treat a single ailment or multiple ailments. The leaves of Lannea grandis were used for diuretic purposes in case of urinary problems. Similarly, crushed whole plants of Typhonium giganteum were topically applied to reduce pain. On the other hand, the roots of Areca catechu were used to treat both helminthiasis and constipation. The leaves and fruits of Ananas comosus were used to treat fever, helminthiasis, and jaundice. In this case, the fruits were used for treatment of fever, while leaf juice was used to treat helminthiasis or jaundice. Mostly the uses of medicinal plants were for common ailments like respiratory tract disorders (cough, pneumonia, asthma, bronchitis), gastrointestinal problems (diarrhea, dysentery, constipation), skin diseases (scabies, eczema, itches), bone fractures, and cuts and wounds. However, the khamals used medicinal plants to treat more complicated diseases like heart diseases, hypertension, diabetes, urinary calculus, sexual disorders, malaria, and leprosy. One plant, Argyreia speciosa, was used to treat small pox when the disease was prevalent.

From the number of plant species used for treatment of various ailments, it appears that gastrointestinal disorders, respiratory tract infections, skin diseases, sexual disorders, and diabetes are common among the Garos. The number of plants used to treat the above disorders or ailments were 18, 10, 15, 8, and 11. Nine plants were used to treat cuts and wounds. Other ailments treated included bone fractures, urinary tract problems, helminthiasis, heart diseases, hypertension, fever, debility, pain, chicken pox, toothache, jaundice, mental disorders, snake bites, measles, menstrual disorders, malaria, leprosy, insomnia, urinary calculus, and head lice. Certain plants were also used as abortifacient, diuretic, anti-emetic, energy stimulant, insect repellent, or as antidote to poison.

3.4. Reported pharmacological activities on plants used by the Garo tribal healers

The various medicinal plants used by the Garo tribal healers of Netrakona district, Bangladesh were screened in the available scientific literature for reported relevant pharmacological activities. The results are summarized in Table 2. It may be seen from Table 2 that 32 medicinal plants out of the 74 plants used by Garo traditional healers have reported pharmacological activities, which validate their traditional use.


We have previously conducted and published an account of an ethnobotanical survey conducted among the Garo tribal healers of Madhupur forest region, Bangladesh (Mia, et al, 2009). The present survey shows that considerable differences exist in the usage of medicinal plants between the Garo healers of Madhupur and the Garo healers of Netrakona district. While the Garo healers of Madhupur used 65 medicinal plants distributed into 43 families for treatment of various ailments, the Garo healers of Netrakona district used 74 plants distributed into 45 families. Out of these plants, only 18 plants were found to be used in common in both areas. These common use plants can be classified into three groups based on the ailments treated. The first group comprised of the same plant being used to treat the same ailment (e.g. use of Mikania cordata for treatment of cuts and wounds, use of Hibiscus rosa sinensis for treatment of dysentery, and use of Aphanamixis polystachya for treatment of skin diseases). The second group comprised of plants, which although not used for treatment of the same ailment, are used for treatment of related ailments (e.g. use of Cissus quadrangularis to treat bone fractures in Madhupur versus use of the same plant to treat wounds and sprains in Netrakona). The third group comprised of plants used to treat different ailments in the two regions surveyed (e.g. use of Achyranthes aspera as an abortifacient in Madhupur, while the same plant was used for treatment of snake bite, diabetes, and gonorrhea in Netrakona). Thus obviously, the traditional healers of the Garo tribe residing in different areas have developed their own unique system of medicinal plant usage. The differences cannot be attributed to geographical availability of plants, for both Madhupur and Netrakona have closely similar climate and vegetation. Thus this difference has arisen possibly from individual clinical practices of the healers with individually conducted trial and error methods. It is to be noted in this regard that the traditional Garo healers do not have any central database of medicinal plants; rather, each healer has developed his own treatment system, which again is dependent on his teacher and his personally developed expertise. As such, treatment with medicinal plants is a continually developing process among the healers and quite possibly has changed both with time as well as area of residence.

The use of a number of medicinal plants by the Garo healers of Netrakona district finds support from scientific studies conducted on these plants regarding their phytochemical components as well as pharmacological activity studies. This validation indicates that the use of medicinal plants for treatment of specific ailments by indigenous healers need not be ignored by modern science; instead, this ethnobotanical information can form the basis for further studies leading to the development of lead compounds and newer drugs. Certainly, the available studies indicate that plants like Centella asiatica, Ageratum conyzoides, Terminalia arjuna, Moringa oleifera, and Aegle marmelos present excellent potential for development of drugs leading to treatment of both widespread but common ailments like gastrointestinal disorders, as well as complicated ailments like diabetes and heart diseases, which are prevalent throughout the world population and which cannot be treated satisfactorily with modern allopathic medicine. Many other plants have not been studied at all scientifically thus far. The importance of the present survey lies in the knowledge gained from indigenous tribal healers, which can in turn, lead to scientific research on the plants, leading to discovery of novel efficacious drugs. The study, through highlighting these medicinal plant species, can also serve an important purpose in the cultivation and conservation of these plants, many of which are getting endangered in the wild.
