INTRODUCTION
The practice of Indigenous Medical Knowledge (IMK) by asing’anga in Zambia is a legalized matter. There are four categories of asing’anga namely diviners, spiritualists, herbalists and midwiferies. All activities pertaining to their practices are regulated and protected by Traditional Health Practitioners Association of Zambia (THPAZ) formed in 1967 under the British Act and the new 2016 Act. Therefore, the association registers and issue certificates to asing’anga who are practicing in different part of the country. The use of IMK is promoted by local people who rely so much on indigenous knowledge to make their decisions on various aspects of their lives. This is related to activities such as growing of food, preservation and preparation of food, medicines as well as their roles in society as males and females. However, IMK is in danger of diminishing because of modern medical facilities and yet there are inadequate efforts from national and organizational institutions to capture this knowledge. This study investigated the preservation measures employed by asing’anga in order to preserve IMK. The paper outlines prevalence of IMK in Southern Africa in the background, the research methodology used, findings and discussion and finally the conclusion.
IMK has existed since the beginning of humanity as Mawere (2014) observed that this knowledge has survived the test of time and history. He further adds that the tacit nature of IMK is intergenerational thus; it is passed by word of mouth from generation to generation by the custodians who hold it such as the elders in society. However, this knowledge is in danger of obliteration as its custodians die and those that remain do not have the whole story or look down upon IMK as backward and also view it as the knowledge of the poor and illiterate; an effect of colonialism that necessitated the adoption of a different way of knowing that devalued most of the IMK present in communities (Makinde & Shorunke, 2013). The colonizer asserts that just like Indigenous Knowledge, traditional medicine does not undergo rigorous testing hence raising a great deal of suspicion. This has been influenced by western knowledge system which is built upon the idea of positivism where truth is established by logical, scientific or mathematical testing (Agrawal, 1995). But Kaniki and Mphahlele (2002) argue that IMK represent the beliefs of a community based on its culture and religion; thus, respect of deities and the conviction that ancestors are the community’s intercessors with God, if not gods in their own right (Kaniki & Mphahlele, 2002).
On the other hand, knowledge preservation denotes the protection or the keeping safe of knowledge, especially indigenous knowledge, from being lost to future generations. Kaniki and Mphahlele (2002:6) assert that indigenous knowledge is mostly passed on by word of mouth. Additionally, arguments may arise because of the perceived fact that preservation is what has necessitated the human race to survive, adapt and adjust over generations. It is also safe to say that people acquire and transfer knowledge with preservation in mind (Maluleka, 2017). However, the ongoing introduction of new technologies put its preservation at greater risk.
In this circumstance, preservation is used to signify the management of indigenous knowledge through the use of both traditional methods such as oral traditions, folklores and other traditional technological method. Modern methods of preservation were used to signify preservation of indigenous knowledge by codifying, documenting and digitizing it. Numerous indigenous knowledge proponents agree that indigenous communities have had their methods and tools of managing and preserving indigenous knowledge such as oral tradition, apprenticeship, artefacts, spirituality, food and seed drying systems; agricultural management technologies such as permaculture and folklores (Stevens, 2008).
This article is an extract from a study that sought to investigate the acquisition, transfer and preservation of Indigenous Knowledge by Traditional Healers in Chibombo District of Zambia. The author makes a case on the need to preserve and promote IMK. Chibombo district of Zambia is located in Central Province and shares boundaries with Chisamba, Kabwe, Kapiri Mposhi, Lusaka, Mumbwa, Ngabwe and Shibuyunji districts. The area has an estimated population of 224,215 as recorded by the Central Statistical Office (CSO, 2010). The district still recognizes a traditional hierarchy of leadership hence falls under the control of a Chief and many Headmen/women who look after the smaller constituent villages. In addition, the area sits between 27 and 29 degrees GMT, hence receiving between 800 and 1,200 millimetres of rainfall every rainy season making it a farming district with a mixture of commercial and peasant farmers where cotton, maize and wheat are grown on a large scale with fishing in the Lukanga Swamps and livestock rearing being the mainstay of the local people’s livelihoods (Daily Mail, 2014). The district faces a number of health challenges such as inadequate health facilities, shortages of personnel, lack of equipment, stock out of drugs and low budgetary allocation which hampers delivery of primary health care. In addition, physical and economic barriers are major obstacles which people face in accessing primary health care facilities and services (Shikabi, 2013).
METHODOLOGY
The study employed hermeneutic phenomenology as it investigated structures of experience of texts whether public, private in form of art or in other material forms (Grbich, 2007). 29 ng’anga registered with Traditional Health Practitioners Association of Zambia (THPAZ) participated in the study from Chibombo District. Data was collected using a semi-structured interview guide through face-to-face interviews which were conducted in different settings, thus part of the interviews was conducted at home of the participants and the other was conducted from the practicing offices at a date and time determined by them. The interview guides were translated into Lenje and Nyanja languages to suit the language they understood well and location. The study utilized linear snowball sampling. Thus, all participants were located through referral by the interviewed ng’anga and so on.
RESULTS
Method of preservation of Indigenous Medical Knowledge by Traditional Healers
In an attempt to keep the unique practice of traditional healing, majority of the healers preserved the knowledge through training interested individuals as well as relatives. One healer [TH:09] said:
“I am training my grandchildren to make sure that this knowledge remains when I am no more. I believe that the knowledge should always be passed on to continue helping those in need within our villages and beyond.”
Another healer [TH:17] added:
“I have been training my children for the past 2 years. I have witnessed them administer herbs to different patients with different illnesses. I know that even if I am no more today, they will continue practicing what they were trained in. Due to the negative perception of the practice from our society, I have not engaged non-relatives in the training even though most of them have shown interest.”
Additionally
“I am training my wife who has now become my assistant. She knows everything because I have engaged her in every process of healing. I also tried to engage my children in the same but they seem not to be interested. In times when we go into the wild for days with my wife to dig the roots and other herbs, our children usually remove the poster for my advertisement.” (TH:22).
Challenges during preservation of Indigenous Medical Knowledge
The study found that the current environment seemed to be contributing to most healers abandoning or refusing to take up practicing roles.
One healer [TH:05] narrated that,
“Most of the people are not willing to learn or be trained in this practice; this can be observed from how fast they forget when we teach them. For instance, I have ten children and I have trained all of them, unfortunately only four have mastered and seem interested.”
Another healer [TH:11] said,
“Those I have trained already reveal challenges of failing to recognize some of the trees we used to create certain herbs from. Further, most individuals are unwilling to take up our role when we are no more.”
The second challenge recorded was expiration.
One healer [TH:02] stressed that,
“The herbs lose power if kept for a long time without being used or administered to any patient. This is determined on were such herbs are kept. So in short the temperature plays a role in either preserving or expiring herbs.”
The third challenge established in this study was spirituality.
A healer [TH:26], who got the knowledge through visions and dreams narrated,
“The fact that I got the healing powers from ancestral spirits, transferring and preserving is quite challenging because for me to know the ailment a patient is suffering from and what I should administer to them, I need to be possessed by the spirits.”
DISCUSSION
Research findings showed that majority of traditional healers were training their families and other interested individuals as a way of preserving the knowledge. The methodologies implored in the process of training involved demonstration (23), documentation (05) as well as mastering (1). These findings infer into a number of things about knowledge preservation. The first process on one hand revealed that trainers demonstrated and engaged interested trainees to acquire the knowledge for continuity sake. On the other hand, healers also exchanged such knowledge among themselves as a way of passing on new skills and practices at individual level. At communal gathering, healers were called upon to demonstrate the value of their skills in preserving and protecting communal events such as traditional ceremonies, through such many healers acquired and in the same vain shared new knowledge and skills for preservation.
As noted by one of the healers in the study, new knowledge was passed to him on how to administer one herb in different ways to treat more than one ailment. A study by Olatokun (2010) aimed at revealing indigenous knowledge of traditional medical practitioners in the treatment of sickle cell anaemia in South-western Nigeria found that knowledge of traditional medical practice was orally preserved and transmitted by word of mouth from generation to generation. Olatokun’s study compliment the findings from this study in that the method of knowledge preservation used is similar and this can be attributed to the fact that most African communities use informal means as a way of training (inculcating skills) the young ones.
The second process showed that in some cases the trainees were given books bearing a list of herbs and the ailments they heal. Such books could have been passed on to many healers from the actual owners to promote continuity and preservation of such knowledge. In the same way, it was revealed that some trainees opted to recording down what seemed challenging to master, for instance adding papers with a name of an ailment in a bottle containing herbs for easy identification. Key informant further alluded that one way through which such knowledge were preserved was by documentation and making available the knowledge to the community through the library space provided by the council.
A study conducted by Issa, Owoeye and Awoyemi (2018) in Kwara state, Nigeria on examining the attitudes and the practice of documentation of Indigenous Knowledge by the traditional health practitioners (THP) revealed that the traditional healers believed documentation of indigenous practice in form of writing and other methods will prevent the knowledge from going into extinction. The findings from the above study compliment this study and the similarity can be attributed to the fact that healers regardless of the communities they are in have developed a desire to witness theirpractice live on through any means even in their absence.
The third process revealed that, on the part of the trainees observing attentively everything the healer was doing for many weeks, months or years of mastering made them a preserve of that knowledge. Among healers, some revealed that being in the presence of old men or women who had been practicing for many years was seen as an opportunity to master and copy how they practiced without their knowledge. Biyela (2016) conducted a study which looked at management and preservation of Indigenous Knowledge in Dlangubo village, South Africa. The results from the study revealed that the community used memory and artefacts to preserve indigenous knowledge. The results from Biyela’s study compliment this study in that the knowledge which is past on and the ways within which the knowledge is passed require memory to be sustained and better used in the future. Another study by Herman (2013) was conducted which looked at the preservation and transmission of indigenous knowledge in diminishing bio-cultural environment in Botswana and Tanzania. The findings pointed those individuals with unique talents or natural gifts like traditional healers, rain-makers and diviners to pass on their skills to academicians and younger generations so as to have the skills well documented for future use. The study by Herman supports this study as the findings also emphasize the passing on of indigenous knowledge as a way of preserving.
Furthermore, challenges during preservation showed three patterns. The first was unwillingness; some children whose parents were healers showed no interest in learning the practice and taking up the role. Further, the study also revealed that some amongst the relatives who showed willingness were already demonstrating signs of failing to recognize the needed herbs after spending time without practicing. A study by Tabuti et al (2004) stressed that indigenous knowledge is acquired and transferred by the willingness to verbalize and share by custodians. The authors further observed that indigenous people were notconstantly willing to share this knowledge with people from outside their communities. The findings from the study above are different from those of this study. on one hand, this study indicated willingness from the knowledge custodians to share to the knowledge to the unwilling relatives while on the other hand, the above study proved the opposite as custodians were not willing to share such knowledge to any outside their communities regardless of family ties. The difference can be attributed to the values upon which both societies place on indigenous knowledge.
The second pattern was expiration. Healers revealed that some prepared herbs that were not administered for a long time expired due to change in seasons. A study by Maluleka (2017) stressed that it was ordinary knowledge that traditional healers mainly use herbs to heal different ailments and these herbs are mostly kept in huts that are cooler inside designed to keep them for longer. Maluleka added that to be able to use those herbs the healers have a way of knowing which herbs to use at the time. The study by Maluleka compliment the findings in this study as both studies show that the usage of some herbs is determined by changes in weather.
The last pattern revealed spirituality. A healer indicated that it was difficult to preserve the knowledge because the herbs and the processes of administering were revealed by the spirit and this happened only when they possess him. Thus, individuals that are called usually recognize their healing gifts through dreams and messages from ancestors are believed to be delivered to them in their sleep (Maluleka, 2017). The findings present a similar occurrence that manifests from the fact that selection of an individual to take over the practice maybe determined by the ancestral spirits and not from a practicing individual.
CONCLUSION
This paper has discussed the preservation methods used by THs for IMK. However, regardless of the available Act to promote and regulate the use of IMK, the genesis of religion had led to many Zambians demonizing the practice while secretly seeking its use in closed corridors. Therefore, there is need for our medical institutions to collaborate with IMK custodians in an effort to cub different illnesses.
