Background: Obesity is a complex, severe and chronic disease that can have an unenthusiastic effect on many systems in human body. In traditional medication, many medicinal plants have been used to treat obesity. The aim of the present study is to present medicinal plants which are available in Bangladesh that proved their anti-obesity activities have been. Method: Bibliographic study was carried out by analyzing conventional text books and peer reviewed papers, consulting wide-reaching accepted scientific databases. In this review, the investigation terms were “obesity” in addition to (“herbal medicine” or “plant”, “medicinal plants” or “medicine traditional”) with no limiting search objects. Later it was cross checked whether the plants were available in the country or not from the Bangladeshi online medicinal plants databases. Findings: More than 100 plants have anti-obesity potentiality; however, only 23 species are available in Bangladesh. The plants are: Achyranthes aspera Linn, Acorus calamus Linn, Aegle marmelos Linn, Allium cepa Linn, Allium sativum Linn, Bombax ceiba L., Coccinia grandis (L.) Voigt, Cucumis melo L., Hibiscus sabdariffa L., Ipomoea batatas (L.) Lam, Morus alba L., Murraya koenigii (L.) Spreng, Nelumbo nucifera Gaertn, Phaseolus vulgaris L., Punica granatum L., Senna siamea (Lam.) H.S.Irwin & Barneby, Shorea robusta Gaertn, Solanum lycopersicum L., Syzygium aromaticum (L.) Merr. & L.M.Perry, Tamarindus indica L., Zingiber officinale Roscoe, Moringa oleifera and Citrus limon (L.). Conclusion: There are a lot of plants in Bangladesh which seem to be a safe treatment source for obesity control. Further researches are recommended to evaluate this potentiality for presenting effective and safe drugs for obesity in the market.


Anti-obesity, Bangladeshi plants, Herbal medication.


Obesity is fetching one of the most widespread health concerns amongst all populations and age groups all-inclusive, ensuing into a significant amplify in mortality as well as morbidity connected to coronary heart diseases, stroke, diabetes type 2, metabolic syndrome as well as cancers [1-4]. Choosing the best treatment for obesity depends on the accurate analysis. There are numerous complementary and integrative practices, including physical activity, dietary programs, surgical interventions, behavioral therapy, lifestyle modifications, medicinal therapies and the use of medicinal plants [5-10].

There are quite a few pharmacologic substances available as anti-obesity drugs, nevertheless they have risky side effects and therefore natural products have been used for treating obesity in many Asian countries and even in Bangladesh. Side effects with anti-obesity drug can differ depending upon the types of drugs we receive furthermore how the drug works. In the table, drug category and common side effects are mentioned. It is to be mentioned that weight loss medications are used beside a low calorie diet and a doctor-approved exercise plan intended for best results. In addition, it is to know that the majority people will get back some or all of the weight they lost when they discontinue using weight loss drugs if not efforts are made to keep their weight loss with diet and exercise. In the Table 1, generic name along with their category and common side effects are noted [11-15].

Drug Name Drug Category Common Side Effects
Phentermine Appetite suppressant Increased blood pressure along with heart rate, insomnia, restlessness, dependence, nervousness,  abuse or withdrawal may occur with long-term use
Orlistat Lipase inhibitor Flatulence, fecal urgency, soft stools, fecal incontinence
Lorcaserin Appetite suppressant Headache, dizziness, nausea, fatigue, dry mouth, constipation and also euphoria may occur with higher doses
Phendimetrazine Appetite suppressant Increased blood pressure and heart rate, dependence, insomnia, nervousness, restlessness
Bupropion  and naltrexone Antidepressant  and an opioid antagonist Nausea, vomiting, headache, fatigue, constipation,  diarrhea, increased blood pressure, anxiety, tremor, hot flush, unusual taste dizziness, insomnia, dry mouth
Methamphetamine Appetite suppressant Increased blood pressure and heart rate, insomnia, nervousness, restlessness, dependence
Benzphetamine Appetite suppressant Increased blood pressure and heart rate, restlessness,  insomnia, nervousness, dependence
Amfepramone  Appetite suppressant Constipation, restlessness, dry mouth,  insomnia, nervousness, restlessness, increased blood pressure and heart rate, dependence
Liraglutide Regulates appetite and food intake. Nausea/vomiting, diarrhea, constipation, headache, heartburn, fatigue, dizziness,  low blood sugar in type 2 diabetes, increased lipase stomach pain, gas, dry mouth

Table 1: Common side effects of anti-obesity drugs.

At the present time, while of high cost and potentially risky side effects, the need for natural products against obesity is under investigation which may be an alternative strategy for developing effective, safe antiobesity drugs and within economical risk [16-18]. It is also known that natural anti-obesity preparations can induce weight loss through several mechanisms with less risk of side effects [19-21].

To date, many reviews on anti-obesity agents have been consummate but focusing only Bangladeshi medical plants with anti-obesity activities still not found. Therefore, the aim of the present review was to collect or update data on potential antiobesity herbal plants available in Bangladesh and assess the scientific data including active components and mechanisms of action against obesity in human.


Search strategy

Conventional text books and databases such as Web of Science, Scopus, and PubMed were searched for scientific articles published till 2017, using the following descriptors: “herbal medicine” or “plant”, “medicinal plant” or “medicine traditional”, without restriction on the language of the articles and without limiting the search items.

Inclusion and exclusion criteria

Both original works and reviews on medicinal plants were considered, including those that cited the plant species referenced for obesity treatment, with botanical identification correctly described according to the Ethnobotanical Database of Bangladesh (EDB) ( and Medicinal Plants of Bangladesh (http://www.mpbd. info/). Ethnopharmacological articles that presented possible methodological bias in terms of sample quality and authenticity of the species described in the study were not considered.

Data analysis

To analyze and manufacture the objects, an exploratory reading of the bibliographic materials were conducted, assessing the title and abstract of the work. After that, the articles that appeared in the results of all were checked. After completing the exploratory analysis, a selective reading of the articles that included plant species with botanical records were done and were checked in as information contained in the consulted periodicals were performed, thus enabling the collection of the data from the bibliographic review. Information on anti-obesity action was obtained directly from the selected articles [22-50].

Results and Discussion

There were more than 100 medicinal plants available worldwide introduced as anti-obesity plants but in Bangladesh, there were only 23 medicinal plants available for this purpose. For easy understanding, information about these Bangladeshi plants is provided in tables. In the Table 2, there is the list of these plants with local names, common names and their family names. In Table 3, the using parts and mechanism actions of the plants are included. Finally, in Table 4, their short description and chemical composition are provided [51-54].

Dosage of anti-obesity medicinal plants

There were various researches held on anti-obesity medicinal plants and still going on. It is to be mentioned that there is not any fixed dose were found for obesity control. In different experiments, the dose ranges is different.


It is very well known that natural alternatives may provide increased health expectancy in obesity control. In Bangladesh, several plants possess anti-obesity potential but have been poorly studied by the local researchers, while others are not even promoted. More anti-obesity data is needed about those plants, but in order to accomplish this, more researches in this area with well-designed clinical trials focused on both safety and efficacy with these plants materials is required.
