Herbal Medicines (HMs) are playing major roles in the health of the millions of people worldwide. Muslim Religious Leader (MRLs), being an important component of the society with huge influence on it, could contribute a lot to promote HM. This study was aimed at evaluating perceptions of the MRLs, their satisfaction and attitudes towards HM in Bangladesh.
This cross-sectional study collected data from a purposive sample of 503 MRLs using an interviewer-administered structured questionnaire during December 2010 and January 2011. Main outcome measures included sociodemographic variables, MRLs' preferences in using HMs, their satisfaction and intent to use HMs in the future, and finally MRLs' attitudes toward HM use.
Although two-fifth (40.4%) of the MRLs preferred HM among different form of complementary and alternative medicines, they used orthodox medicine (OM) more frequently than HM in last one year. Majority believed that HM was effective for all age groups (52.6%) and both sexes (74.5%). One-third felt that HM was more effective for chronic diseases, 68.5% felt that it only promotes health, and 40.8% said it keeps them relaxed. About 98.0% of the respondents experienced 'no harm' but 'benefit' from HM; naturally, they were satisfied with HM and were willing to recommend it to others. Urban, older (>40 years), and 'single' respondents were more likely to use HM (gender and education adjusted odds ratios = 1.7 [95% confidence interval, CI = 1.1-2.6], 1.9 [95% CI = 1.3-3.0], and 1.6 [95% CI = 1.2-2.1], respectively). Overall, respondents exhibited very positive attitude towards HM with mean score of 4.2 (range, 3.7-4.6) of a 5-point Likert scale (Score 5 for strongly agree to 1 for strongly disagree).
We report adequate perceptions, satisfaction, and very positive attitudes towards HM among MRLs. Mass media had a significant contribution towards its promotion. If HM are to assume a respected place in the contemporary healthcare, its acceptance among general population needs to be established through incorporating MRLs in the process of HM promotion in Bangladesh.

Complementary and Alternative Medicine (CAM) includes medical and healthcare systems, practices, and products that are not currently considered as an integral part of orthodox medicine (OM) . In spite of existence of modern and sophisticated healthcare systems in the Western world, millions are turning back to traditional herbal medicines in order to prevent or treat many illnesses, and a reasonable proportion of drugs dispensed in community pharmacies now contain drugs extracted from plants . The higher use of CAM among western society is also reflected in the developing world, indicating that its use is increasing worldwide [3–5]. This may in part reflect a need to fill gaps in conventional Western medical care, including a need for improved therapeutic efficacy, greater cultural or linguistic relevance, and alignment with personal beliefs . It is estimated that 30% to 50% of the general adult population of industrialized nations use one form of CAM or another . The overwhelming majority of people in South Asia including India, Sri Lanka, Bangladesh, and Nepal has been looking up to Ayurveda in its pure form or some of its variations in some form or other, for relief of various ailments .
Many studies done in western countries have documented that CAM use is both very common and varies among populations . No doubt that CAM has good values in treating many diseases, which can save lives of many, particularly in the developing countries . In the country like Bangladesh, CAM can play a pivotal role for the country's ever poor public health sector.
In Bangladesh, CAM has long been practiced and it is estimated that 70-75% population of the country still use CAM for management of their health problems of various kinds . Bangladesh is full of medicinal plants which is a potential source of drugs. Drugs from these herbal plants have been widely used even in this modern era. Traditionally it is believed that these herbs have very little side-effects and it cost almost nothing in few cases. So, it can solve the economic problem for the poor . Broadly speaking, four types of CAM are primarily practiced in Bangladesh namely herbal, homeopathy, religious, and magical methods. Based on the existing rich local plant diversity, the tradition of indigenous herbal medicine systems has formed a very important component of the primary healthcare system of Bangladesh . The herbal method of CAM mainly uses plant derived medicines and consists of ayurvedic and unani systems in Bangladesh, of which Ayurveda is the most popular. Both registered and unregistered (locally known as Kabiraj) herbal practitioners are practicing in the country at present. Homeopathy is based on the basic principles of law of similarity, direction of cure, principles of single remedy, the theory of minimum diluted dose, and the theory of chronic disease which is intended to trigger immune system of human body . Religious and magical methods include torture, charms, magic, incantations, religious verses, amulets and rituals like sacrifices, appeasement of evil spirits, etc. Spiritual/Jharfuk is a form of religious method of CAM where religious verses are recited to spiritually heal the ailment of the patient. Although religious methods are widely practiced in Bangladesh, they are not officially recognized as scientific medicines or methods of treatment . Notwithstanding Ayurvedic and Unani medicines are very similar in origin from plants, few people can differentiate these subtle differences. Therefore we intended to know respondents' opinion for herbal medicines (HMs) as a whole, not specifically on Ayurvda or Unani system.
Bangladesh as a Muslim country is highly influenced by religion and Islamic values influence every aspect of people's life. Muslim religious leaders (MRLs) are very influential and trustworthy personnel who are important in shaping social values . Considerable influence of the MRLs can have a positive role in raising the awareness of the society about healthy and nondiscriminating behaviours towards HM. They can stimulate a political response and create a supportive environment in favor of HM. They also can play an important role in spiritual counselling and care for patients and their families.
Despite being in use of CAMs for more than 3000 years, few properly designed trials have scientifically examined the clinical potential and peoples' trust on Herbal and other medications . In Bangladesh also, there has been a great paucity of information on it. Exploring the perceptions and attitudes of MRLs will pave the way to incorporate HM in the healthcare system and to plan culturally appropriate evidence-based strategies to combat diseases and assist health care providers in providing needed treatment and care. Therefore, this study was aimed to explore MRLs' perceptions on HM and their attitudes towards it. This study is a unique one as no study has been carried out till date to determine the perceptions and attitude of the MRLs about HM in the country. This study may be a dependable host of information required for further studies in the relevant fields.
Design and sample
This cross-sectional survey was conducted by face-to-face interview by trained staffs using a structured questionnaire during December 2010 to January 2011. Four data collecting staff were trained on how to collect data from the respondents. Their interviewing skills were assessed through pretesting the questionnaire and interview among 15 MRLs. Participants were chosen purposively from MRLs with educational background in Islamic religion under Madrasah education system. Madrasah education system, a unique system of Islamic religious education, are divided into five distinct levels - Ibtedai (elementary, 1-5 years), Dakhil (secondary, 6-10 years), Alim (higher secondary, 11-12 years), Fajil (undergraduate, 13-14 years), and Kamil (Masters, 15-16/17 years) . These Madrasahs teach all the required modern subjects, such as English, Bengali, Social studies, Maths, Geography etc. in addition to religious subjects . The sample size was consists of 503 MRLs from urban and rural areas of two districts (Dhaka and Brahmanbaria) of Bangladesh. Majority of the participants were involved in teaching in Madrasah and leading prayers in the mosques as 'Imam'. Participants with educational qualification at least Dakhil and age group between 19-60 years were included in this study. Participants who did not use any form of CAM in their life-time were excluded. The subjects were informed that they were free to decline answering any question with which they were not comfortable. Anonymity of their personal identity was preserved. Written informed written consent was obtained from every participant before interview. As this study was not involved in experimental research involving human subjects, ethical approval was exempted.
The questionnaire was divided into three parts: Part A contained socio-demographic information of the study participants, such as age, sex, marital status, monthly income, occupation, and self-rating of their health status; Part B contained information about their use of HMs; and part C contained 13 positive questions to assess attitudes of the respondents towards HM. The questionnaire was generated with modification of Patterson and Arthurs' published questionnaire . Then it was validated by three expert reviews for clarity, comprehensibility, and contents. Finally, the questionnaire was translated into Bengali and changes were made to make it understandable for the respondents before data collection in the field and back translated into English. To measure the attitudes of the respondents towards use of HM, we used 13-item scales. The participants were asked to indicate their level of agreement with items on a 5-point Likert scale ranging from 1 = "Strongly disagree" to 5 = "Strongly agree". The total possible score were ranged from 13 (Negative attitude to use HM) to 65 (positive attitude to use HM).
Standard methods of exploratory data analysis (means, standard deviations [SDs], medians, frequencies) were used to depict the distribution of the principal variables. Univariate tests of statistical significance, such as independent sample t tests for continuous variables and Chi-square tests for categorical variables were used to draw preliminary conclusions. Inferences from these results were further explored using multivariable logistic regressions to estimate odds ratio (OR) and 95% confidence interval (CI). Level of statistical significance were set at P = .05.
MRLs' attitudes toward the use of HM were determined first by computing a total score on the 13-item questionnaire. The mean total score was 54.8 (SD ± 3.7) out of a possible 65. To examine the association of the attitude score with respondents' demographic characteristics, the total score was dichotomized at the median . Accordingly, scores in the range of 0-55 were defined as 'negative attitude' and low likelihood to use HM, whereas scores between 56 and 65 were defined as 'positive attitude' and higher likelihood to use HM.

To the best of our knowledge, this is the first study focusing on the perceptions of HM use and attitudes towards it among the MRLs in Bangladesh. The key findings of this study were: 1) majority of the MRLs preferred HM over other CAMs; 2) higher satisfaction of MRLs towards HM and their willingness to recommend it to others in their family, friends and so on; and 3) their positive attitudes to HM.
Although there had been a notable advancement in the field of HM in the Western countries, Bangladesh is still struggling to give HM a respectable position in the mainstream healthcare system. Following independence of Bangladesh, the Board of Unani and Ayurvedic Systems of Medicine, Bangladesh was restructured with Bangladesh Unani and Ayurvedic Practitioners Ordinance of 1972 . Since then, several steps had been taken to strengthen HM in Bangladesh. However, to date there appears to be no harmonized system of overseeing the practice of HM in Bangladesh. But efforts to formulate a law to recognize, coordinate and regulate the practice of HMs are underway.
We found that preference for HM use was very high among the respondents which are consistent with the findings of other published reports of similar design . However, their health seeking behaviour contradicts their saying that 'they prefer OM - if the treatment cost were same'. This discrepancy may be explained by understanding that the treatment sought is determined by the ailment one is suffering from. For easily diagnosed ailments and for those with well-established cures, e.g. malaria, they prefer to go to OM practitioners (OMPs), but for difficult to diagnose and chronic illnesses they seek the services of HM practitioners (HMPs) . Affordable cost of HM may be another reason of such discrepancy. In Bangladesh, HM use is still limited to the middle- and low-income groups of general population. Because of lack of a health insurance system, patients must pay treatment costs out of their pocket. Middle- and low-income people naturally choose to use HM first, not because of their choice, but because HM is cheap, more closely corresponds to their ideology, and is less paternalistic than OM . However, preference of HM may be higher in our study than in general population, especially respondents with higher income chose HM more than those with lower income (P = .04). Religious affiliations may also appear to influence the pattern of use of HM in every population . This is also reflected in our result that 'Spiritual/Jharfuk' was the second popular CAM among them. Religious influences over HM is also reported by Ezeome et al. in their study saying that the high proportion of Catholics among their study population explains the increased prevalence in the use of religious relics and items such as black stone, olive oil, and mustard seed . Other explanations of liking HM but using OM may be: their less confidence on the scientific basis of HM; OM is more effective than HM; OMPs make better diagnoses of illnesses; the people are more familiar with OM; and some charlatans charge a lot of money to cure simple ailments . There are not enough scientific evidences which can surely indicate that scientific basis of HM is beyond doubt and comparable with modern medicines like Allopathy . Over- and inappropriate use of HM is also rampant. There is a obvious shortage of skilled human resources in the field of HM as it was reflected from the report of Ashraf et al. . Still now after a long time of Ashraf et al.'s study, there has been no remarkable improvement in the HM system. Quackery in the field of HM is also quite common. Even a layman without proper know-how can become an HMP to look for additional earnings. This type of practice may pose serious threats to public health often by erroneous diagnosis and incorrect treatment using wrong or fake medications .
Surprisingly, we did not find any differences in preferences of HM by gender and level of education which has been observed in many other studies [7, 21, 22]. This could be subject of sampling or reflect an aspect of preferences by MRLs. However, urban and older participants showed significantly higher preference to HM. Similar findings were reported by many other studies [21, 22]. It is expected that increased age is commonly associated with greater health ailments, especially chronic diseases [7, 23–25], and higher familiarity with traditional methods, and reluctance over OM .
It is well known that South Asian countries, like Bangladesh, India, Nepal, and Sri Lanka bear many cultural and religious practices in common. Especially they are highly influenced by religious rituals in almost every spheres of their life including medication. A major portion of the CAMs in these countries are dominated by use of religious practices. For example, the herb Tulsi also called holy basil (sometimes spelled "Tulasi") has been widely known for its health promoting and medicinal value for thousands of years. Commonly called sacred or holy basil, it is a principal herb of Ayurveda, the ancient traditional holistic health system of India. Holy basil is known as "The Incomparable One", "The Mother Medicine of Nature", and "The Queen of Herbs" . Dhami-jhankri, Pandit-lama-gubhaju-pujari and Jyotishi are the leading 'Faith healers' in Nepal having huge influence on CAM practice in Nepal . Thereby, it is expected that they are also motivated to a great extent by the religious leaders before deciding to use HM in their sickness. Importantly, religious influences are abundant in all classes of population in Bangladesh. For any kind of sickness or other issues people always rely on the suggestion of the MRLs. Again because of faith-related matters, these MRLs prefer to use something which has more natural value like herbs in HM. Their feelings were well reflected in our study where we found that they were very satisfied with HM and they want to recommend others to use HM. This may not be because their higher satisfaction with all aspects of diseases and their treatment with HM, rather because of their belief that HM is less harmful than OM. Given them enough evidence that HM is equally reliable in terms of the scientific basis with OM could convince them more towards HM. Whatever may be the reason, it is a very meaningful observation to promote HM farther in Bangladesh. In addition, they stated very positive attitudes towards questions related to HM which can add momentum in their efforts to promote HM.
We found mass media play the leading role in promoting HM in Bangladesh followed by family members and friends which was in line with other published report . It is evidenced that aggressive advertisements of HM on various media including newspapers have resulted in increased sales all over the world . However, exaggerated and superfluous advertisement in the mass media has also lost its faith especially from the educated people. Very often, less educated and low-income people are deceived out of this advertisement which is again put negative impact on the HM. The advertisements in the newspapers promise to prevent and even cure incurable conditions - AIDS (acquired immunodeficiency syndrome), cancer, heart disease, diabetes, arthritis, multiple sclerosis and so on . Very often they claim that HM can give absolute guarantee of cure even when conventional medicine fails. Consequently, this weapon of attracting people towards HM is getting blunt. At this crucial point, it is necessary to find some alternative to return faith of people towards HM.
Our findings of higher satisfaction and positive attitude towards HM among MRLs could show us an important direction towards promotion of HM in Bangladesh. Nurturing adequate perception about HM, as expressed by the MRLs, lead to attainment of positive attitude towards it. Having such positive attitudes can persuade people to use and advocate HM to the community people. In addition, these MRLs need more exposure with training and orientation about HM to be enough knowledgeable on the scientific basis of HM and its safety. Only then, it may be convenient and cost-effective to seek help from the MRLs in the progression of HM development in Bangladesh. As such, the mass media could regain their lost faith from the people if they can incorporate MRLs to promote HM.
Several limitations of our study need to be pointed. As Ayurveda is an important component of herbal medicines and had its roots from Hindu scripture Samaskrutham, a potential conflict of religious belief among our respondents cannot be ruled out. Despite this possibility, Ayurveda was the most popular among all forms of CAMs in Bangladesh which could justify the rationale of considering these MRLs in HM promotion in Bangladesh. Our questionnaire was developed after review and modification of existing studies, which were from industrialized Western countries. Although we made substantial changes to make it relevant to our local environment, possibility of not conveying important insights on the Bangladeshi respondents exists. A properly designed qualitative study can provide such insights. We included only a small sample of MRLs which might be a threat to the generalizability of the result. Finally, given the long history of HM in Bangladesh, and its intimate integration into daily life, some participants may have been employing Herbal concepts and methods, such as use of specific medicinal herbs or spices in cooking, without recognizing it as such, and therefore underestimation of HM use cannot be ruled out. Despite these shortcomings, we believe this study gives a reliable picture of HM use among MRLs in Bangladesh.
This study reports adequate perceptions about use, effectiveness, safety, availability, and affordability of HM among MRLs. They were highly satisfied with HM and ready to recommend others. Mass media like Radio, Television also had enormous impact on its promotion. Taken together, these findings suggest the need to educate MRLs about the scientific basis of HM and to utilize them generously to solicit information about use of HM. Government's recognition and its implementation in the healthcare machineries are important to promote HM in Bangladesh. Nevertheless, if HM are to assume a respected place in the contemporary healthcare, its acceptance among general population needs to be established through incorporating MRLs in the progression of HM promotion in Bangladesh. Future empirical research with larger sample including leaders of all sects could precisely formulate next step to establish HM in Bangladesh.
