Appraisals of Bangladeshi medicinal plants used by folk medicine practitioners in the prevention and management of malignant neoplastic diseases.

1. Introduction

Cancer is defined as an abnormal growth of cells caused by multiple changes in gene expression leading to deregulated balance of cell proliferation and cell death. Cancer is those tumors [1] that have developed the ability to invade the surrounding normal tissues. Cancers are caused by exogenous chemical, physical, or biological carcinogens in humans and the mechanisms of carcinogenesis are often multifactorial and complex. Different factors may act by different mechanisms and at different stages of tumor development [2]. A cancerous cell is traveling throughout the body using the blood or lymph systems, destroying healthy tissue in a process called invasion, and that cell manages to make new blood vessels to feed itself in a process called angiogenesis. Tumors may activate angiogenic inhibitors (angiostatin and endostatin) that can modulate angiogenesis at both the primary site and downstream sites of metastasis [3, 4], when a tumor successfully spreads to other parts of the body using the blood or lymph systems known as metastasis.

Cancer is a leading cause of death in the western world. In the United States and a number of European countries, cancer is the second leading destroyer after cardiovascular diseases [5]. Cancer can occur at any age and the average age at the time of diagnosis for cancer is 67 years, and about 76% of all cancers are diagnosed at the age of 55 or older. Although cancer is relatively rare in children, it is the second leading cause of death in children ages of 1-14. In this age, leukemia is the most common cause of death. The overall death rates due to cancer have almost tripled since 1930 for men and gone up over 50% for women [6]. World Health Organization (WHO) estimates that some 84 million people will die of cancer between 2005 and 2015 around the world. In 2007, there were 7.9 million deaths from cancer, around 13 percent of all deaths.

1.1. Cancer Epidemiology in Bangladesh. The National Institute of Cancer Research and Hospital (NICRH) started a cancer registry in 2005 for the first time in Bangladesh along with the World Health Organization (WHO). This report covers three years from 2005 to 2007. Data were collected from 24,847 cancer patients who appeared in the NICRH for the first time [7]. Among them, 10,847 (57.6%) were males. Lung cancer was the leading cancer (17.3%), followed by cancers of breast (12.3%), lymph nodes and lymphatics (8.4%), and cervix (8.4%) for sexes combined in all ages. In males' lung (25.5%) and in females breast (25.6%) and cervical (21.5%) cancers were predominant. In children aged 14 years or younger, lymphoma, retinoblastoma, osteosarcoma, leukemia, and kidney cancers were most prevalent. Lung cancer in males and cervical and breast cancer in females constitute 38% of all cancers in Bangladesh [7]. According to the WHO data published in April 2011, oral cancer deaths in Bangladesh reached 11,562 or 1.21% of total deaths. The age adjusted death rate is 12.52 per 100,000 of population ranking Bangladesh 4 in the world. There are more than one million (10 lakh) cancer patients in Bangladesh while approximately 200,000 new patients, mostly women, are added every year creating a social burden on the country [8, 9].

Various plants have been used against cancer and tumor in traditional medicine system of Bangladesh since many years. Traditional medicinal knowledge has been a means towards the discovery of many modern medicines [10]. Traditional medicine is practiced in Bangladesh by folk medicine practitioners, also known as Kabirajes who utilize various formulations of medicinal plants in most of their preparations. We have observed that the Kabirajes of various districts and areas use diverse varieties of plants for the treatment of schizophrenia and psychotic problems [11], cardiovascular problems [12], eye infections [13], snakebite [14], diabetes [15], gastrointestinal disorders [16, 17], HIV/AIDS related infections [18], rheumatoid arthritis [19], cattle diseases [20], and so on.

It was objective of the present study to conduct a randomized ethnopharmacological survey to learn more about the medicinal plants used by folk medicine practitioners of Bangladesh for the treatment of cancer and also to do comprehensive study on several published articles attributed to the in vivo or in vitro anticancer properties of these species. The anticipation was that the medicinal plants used by the Kabirajes can prove to be a useful source for further scientific studies leading to discovering more efficacious antineoplastic drugs.

2. Methodology

2.1. Geographical Location of the Survey Area. The present randomized surveys were carried out between October 2013 and March 2014, among the Kabirajes of three districts of Bangladesh, namely, Jessore, Khulna, and Narail. Jessore district geographically is in the southwestern region of Bangladesh. It is located at 23[degrees]10'0" North, 89[degrees]13'0" East, bordered by Khulna and Satkhira district to the south, India to the west, Magura and Narail district to the east, and Jhenaidah district to the north. Khulna and Narail district geographically coordinate at 22[degrees]48'0" North, 89[degrees]33'0" and 23[degrees] 10'0" North, 89[degrees]30'0" East, respectively. These three districts (Figure 1) are a part of Khulna division.

The surveys were conducted with the help of a semistructured questionnaire and the guided field-walk method [21, 22]. A total of 5 Kabirajes (36-60 years) were interviewed during the surveys. Kabirajes were asked whether they know about cancer and whether they treat the cancer on a regular basis. Kabirajes were selected based on their confirmatory answer to both questions. The Kabirajes mentioned the plants with which they treated cancer and took the interviewers to spots from where they collected the plants. All interviews were conducted in the Bangla language. The plants were shown along with providing of local names and the parts used. Plant specimens were collected and dried in the field and later brought back to Dhaka for complete identification at the Bangladesh National Herbarium. Nomenclature of the identified species was documented from the plant list database [].

3. Results

A total of 20 plant species were obtained from the Kabirajes of the three districts surveyed. The results are summarized in Table 1. These plant species are wild and belonged to 17 families. The Acanthaceae, Cucurbitaceae, and Fabaceae family contributed two plants each; the rest of the families contributed one plant each. Whole plant as well as plant parts like leaves, barks, roots, fruits, and seeds was used for preparing medicine. Leaves constituted the major plant part used, forming 40.6% of total uses. Roots, fruits, and seeds each constituted accordingly 15.6%, 12.5%, and 9.4% of total uses. The other plant parts (whole plant, stem, bark, flower, and tuber) mentioned constituted, respectively, 9.4 and 3.1% of total uses (Figure 2).

3.1. Types of Cancer. Among developed countries, the incidence and mortality rates for various cancers are almost the same. Lung cancer is the most common cancer among men in both developing and developed countries of the world and breast cancer is the most common cancer in women. Annually, the global death rate for cancer is estimated to be more than 6 million people and over 22 million individuals have been diagnosed with cancer worldwide [23]. Table 2 has listed the types of cancer.

4. Discussion

Many developing countries have intensified their efforts in documenting the ethnomedical data and scientific literature on medicinal plants. In 2000, natural product derivatives were involved in 14 of the top 35 drugs based on worldwide sales [24]. Cancer chemoprevention with phytochemical compounds is a developing plot [25]. Medicinal plants have been used for cancer treatment in many countries of the world from a prolonged period of time [26,27] and the treatment or prevention is attributed to their safety, low cost, and oral bioavailability as well; natural plant derivatives claimed extensive scientific screening and clinical experiments for the development of anticancer drugs [28]. Over 3000 plants species have been reported to have anticancer properties [29] and about 35000 plant samples from 20 countries have been collected and around 114,000 extracts were screened against tumor systems used as a primary screen [30]. Clinically active antineoplastic agents should be able to prolong the survival and decrease the leukocyte count of blood of tumor-bearing animals [31]. Examples of some well-known plant-derived antineoplastic lead compounds along with their specific mechanism of actions are summarized in Table 3.

4.1. Appraisement of Bangladeshi Medicinal Plants Used by the Folk Medicine Practitioners for Antineoplastic Properties. Secondary metabolites are compounds belonging to varied chemical groups that exert biological activities both on human and animal cells. Products of secondary metabolites are the main phytochemical constituents with various pharmaceutical properties serving either as protective agents against various pathogens or growth regulatory molecules. These physiological functions are the effects on cancer cells or tumor development inhibition. Plant-derived commercial anticancer drugs (vinblastine and vincristine from Catharanthus roseus) are still produced by isolation from growing plants [32]. In Table 4, we have listed some reported plantderived chemical compounds from the antineoplastic plants used by the Bangladeshi folk health practitioners in the treatment of cancer.

4.2. Abelmoschus moschatus (Musk Mallow). Hydroalcoholic seed and leaf extracts of Abelmoschus moschatus exhibited antiproliferative activity against colorectal adenocarcinoma and retinoblastoma human cancer cell lines [33].

4.3. Acanthus ilicifolius (Holly Mangrove). The ethanol leaves' extract of the plant was found [34] to be cytotoxic towards lung fibroblast cells in MTT assay. Another study [35] reported that the plant extract has been shown to prevent DNA alterations in a transplantable Ehrlich Ascites carcinoma-bearing murine model and in enlargement of the survival of the animals against the proliferation of ascites tumor. Ethyl acetate extract of the whole plant of A. ilicifolius has a potential cytotoxic activity on HeLa cell and KB cell lines by comet assay [36]. Active compounds of A. ilicifolius flower play a role in killing Artemia salina nauplii and can be considered as potential cytotoxic agents as well as future candidate for cancer therapy [37].

4.4. Aristolochia indica (Indian Birthwort). The cytotoxicity and antitumor activity of the chloroform extracts of Aristolochia indica were assessed in human breast cancer cell line by MTT assay using taxol as standard and showed pronounced anticancer activity against Ehrlich Ascites Carcinoma cell line [38, 39]. Aristoloside compound was reported to inhibit carcinogenesis [40]. Aristolochic acid was reported to possess various biological activities including antiadenocarcinoma, antineoplastic [41], and antitumor activities [42].

4.5. Borassus flabellifer (Asian Palmyra Palm). Dammarane triterpenoid 1, isolated from Borassus flabellifer seed coat, inhibits tumor necrosis factor-[alpha] and showed good antiproliferative activity against pancreatic cancer cell line. Apoptosis inducing activity was confirmed based on increased sub-G0 phase cell population in cell cycle analysis, loss of mitochondrial membrane potential, elevated levels of cytochrome c, nuclear morphological changes, and DNA fragmentation in MIA PaCa-2 pancreatic cancer cells [43]. B. flabellifer seed coat extracts were screened in another study [44] for their possible anticancer activity on growth of the HeLa cells and these preliminary studies indicated that even the lower concentrations of plant extract showed significant antiproliferative activity.

4.6. Blumea lacera (Blumea). There is an in vitro study [45] that showed that Blumea lacera exhibited broad spectrum antileukemic activity against K562, L1210, P3HR1, and U937 leukemia cells. Methanolic extract of B. lacera leaves has also showed cytotoxic activity against human gastric adenocarcinoma cell line, human colorectal adenocarcinoma cell line, and human breast ductal carcinoma cell line [46].

4.7. Cannabis sativa (Hemp). The interest in anticarcinogenic properties of cannabinoids was renewed after the discovery of the endocannabinoid system [47]. The administration of A9THC, A8-THC, and cannabinol inhibited the growth of Lewis lung adenocarcinoma cells in vitro as well as in vivo after oral administration in mice [48]. Antitumorigenic mechanisms of cannabinoids are showing their ability to interfere with tumor neovascularization, cancer cell migration, adhesion, invasion, and metastasis [49]. The mechanism of cannabinoids' anticancer action depends on the ability of their agents to stimulate autophagy-mediated apoptotic cancer cell death; thus, cannabinoid action helps in cancer cell death, impairs tumor angiogenesis, and blocks invasion and metastasis [50] and cannabinoids are currently also being tested as anticancer agents in phase I/II clinical studies [51].

4.8. Cucurbita maxima (Pumpkin). Methanol extract of Cucurbita maxima aerial parts has been performed against Ehrlich Ascites Carcinoma model in mice by Saha et al. [52] for the antitumor activity and the results revealed that C. maxima possesses significant anticancer activity which may be due to its cytotoxicity and antioxidant properties. Lasparaginase is an antineoplastic agent, identified from fruit of C. maxima, used for treatment of a type of cancer that is acute lymphoblastic leukemia and non-Hodgkin's lymphoma [53] as well as being experimentally used as an anticancer agent in human patients [54, 55].

4.9. Dillenia indica (Elephant Apple). Leaf powder of Dillenia indica is given in treatment of breast cancer [56]. The methanolic extract of D. indica has been found to have significant antileukemic activity in human leukemic cell lines U937, HL60, and K562 [57]. Methanolic extracts of betulinic acid were prepared from the D. indica fruits inducing apoptosis in HT-29 cells via mitochondrial dependent pathway and proving to be a potential therapeutic agent for colon cancer [58].

4.10. Dioscorea bulbifera (Air Potato). Petroleum ether fraction of the plant showed potential effects against HepA with microstructure abnormality of HepA cells surface [59]. Immune system modulation might be related to antitumor effects of D. bulbifera rhizome, as reported in S180 and H22 tumor cells bearing mice [60].

4.11. Emilia sonchifolia (Lilac Tasselflower). The aqueous and methanolic extracts of the leaves of Emilia sonchifolia gradually exhibit antitumor activities [61]. The n-hexane extract of E. sonchifolia has anticancer effect and is rich in terpenoids [62] and terpenoids were evaluated for their potential antineoplastic activity in various human cancer cell lines such as gastric, pancreatic, and colon carcinomas [63].

4.12. Erythrina variegata (Tiger's Claw). Steroid derived from the stem bark and the leaves of Erythrina variegata showed anticancer activity against in vitro breast cancer cell T47D [64]. Alkaloids (10, 11-dioxoerythratidine and crystagallin A) extracted from the leaves and stem bark of E. variegata plant strongly stated in vitro anticancer activity against breast cancer T47D cell lines in vitro using the Sulforhodamine B (SRB) assay [65].

4.13. Hygrophila auriculata (Marsh Barbel). The effect of H. auriculata on carbohydrate metabolizing enzymes in N-nitrosodiethylamine induced hepatocellular carcinoma in rats [66]. The aqueous seed extract from H. auriculata displayed selective cancer cell cytotoxicity with an IC50 value of 0.22 mg [mL.sup.-1] against colon cancer cells [67]. In vitro study of H. auriculata extracts has reported antitumor and NFkB inhibition [68]. Ahmad et al. reported antitumor activity from plant extract against chemically induced hepatocarcinogenesis in Wister rats [69].

4.14. Moringa oleifera (Drumstick Tree). A hydroalcoholic extract of Moringa oleifera study revealed possible chemopreventive potential against chemical carcinogenesis [70]. Different leaf extracts of M. oleifera produced significant cytotoxic effects on human multiple myeloma cultured cell lines [71]. A study [72] showed that leaves extract of M. oleifera can significantly obstruct the growth of cultured human pancreatic carcinoma cells by inhibiting the NF-[kappa]B signaling pathway. Most of the anticancer studies of M. oleifera have not focused on the molecular basis of the tumor-suppressive activity but strongly suggested that it could potentially be a supreme anticancer candidate specific to cancer cells [73, 74].

4.15. Nymphaea nouchali (Blue Water Lily). The methanolic extract of Nymphaea nouchali roots has showed inhibitory activity towards tumor promoter in the Raji cells [75].

4.16. Persicaria hydropiper (Water Pepper). In vitro antiproliferative activity of Polygonum hydropiper (synonymy) extracts was evaluated against cervix epithelial adenocarcinoma, skin epidermoid carcinoma, and breast epithelial adenocarcinoma cells and the results confirmed substantial cell growth inhibitory activity against one or more cell lines [76].

4.17. Trichosanthes kirilowii (Chinese Cucumber). A triterpenoid compound named cucurbitacin B isolated from Trichosanthes kirilowii showed the potent inhibitory activity against HIF-1 activation induced by hypoxia in various human cancer cell lines. In vivo studies confirmed the inhibitory effect of cucurbitacin B on the expression of HIF-1[alpha] proteins, leading to a decrease growth of HeLa cells in a xenograft tumor model [77]. Cucurbitacin D isolated from the plant has also been shown to suppress proliferation of HT29 human colon cancer cells [78] and the compound could be potent therapeutic agent for breast cancer by blocking tumor cell proliferation and inducing apoptosis through suppression of STAT3 activity [79] and it could also induce apoptosis in human hepatocellular carcinoma cells [80].

5. Conclusions

Among twenty plant species, four of the species used by folk medicine practitioners have no strong published data regarding anticancer or cytotoxic activities. These 4 species are C. inerme, M. paniculata, S. sesban, and V. officinalis. From just a brief survey of the literature, it appears that the rest of the sixteen plants used by the Kabirajes in three districts of Bangladesh present considerable potential in the treatment of cancer. Further scientific studies need to be conducted on these plants towards discovery of lead compounds, which can lead to formulation of new drugs for the prevention and management of malignant neoplastic diseases with giving less or no side effects.
