Nombulelo Shange, Lecturer in the Department of Sociology, asks what it would look like if we looked inward and invested in our own indigenous methods of nurturing and encouraging this and similar practices? Could other important scientific innovations emerge from it?

Opinion article by Nombulelo Shange, Lecturer in the Department of Sociology, University of the Free State.
Last year I wrote an opinion piece on the importance of indigenous knowledge, especially in healing practices. The piece detailed the origins of modern vaccines as an old, culturally appropriated African practice that was instrumental in fighting smallpox in 1700s Europe. That piece is perhaps even more significant this year, as many Africans are afraid of the COVID-19 vaccine. The hesitancy comes from a distrust of Western medicine, which has been responsible for many atrocities all over the world, as well as the South African biological warfare created by the apartheid government and led by Wouter Basson, who was dubbed ‘Dr Death’. 

African knowledge systems have come a long way – from being overlooked as valuable sciences or being misrepresented by Western scholars, who for a long time saw themselves as the only suitable custodians of our experiences, ideals, history, culture, and knowledge. Today, although a lot more needs to be done, we are seeing a rise in African intellectuals, practices, and solutions. In the academy, we see this in the calls for decolonised education, which has emphasised the importance of Southern African scholarly contributions locally and internationally. 

In our day-to-day lives, we also see this shift towards reclaiming African solutions to deal with modern-day challenges. Practices such as visiting sangomas/traditional healers and the general practising of African traditional religion were seen as taboo or often labelled as hedonism. Many were forced to acknowledge their ancestors or perform sacrifices in private. But today, many are openly practising their cultural rituals when they want to give thanks for good fortune, when they are struggling to find employment, and for both physical and emotional healing that individuals or the collective needs. Although not ‘scientifically verified’, the African herb called umhlonyane helped many during the COVID-19 pandemic, especially during the major waves that overwhelmed and threatened to cripple our healthcare system. Many have turned to this herb as a solution to help them fight COVID-19. Umhlonyane is commonly used by sangomas for a variety of reasons; to boost the immune system, for patients with illnesses that attack the respiratory system, and many other things. This kind of revitalisation and mainstreaming of indigenous knowledge systems and epistemological pedagogies can undo challenges such as vaccine hesitancy and general distrust of biomedicine, while elevating African knowledge.

The missing link

Despite these and many other positive strides that place African knowledge at the forefront, something is still missing, because we are still far from where we need to be as a continent. There are many things we can draw from to make sense of why the progress is slow. We could draw from the usual arguments around the missing, undervalued African Renaissance. We could also argue that while African ideals are gaining prominence, they are often only invoked as an ‘alternative’ or afterthought. Arguably, even with umhlonyane, it was only from desperation that people turned to it. All of these are valid, but I also what to argue that we are limited by a kind of epistemological slavery, where we use conflicting Western systems of knowledge production in producing African knowledge. We rely on Western methodologies for knowledge production, Western schooling systems for how we engage with and use the knowledge, and even Western systems for how we store and preserve the knowledge. 

Trapping African knowledge in Western epistemology

The April Cape Town fire, which has spread to the University of Cape Town and destroyed the African Studies library, is one illustration of the danger of trapping African knowledge in Western epistemological systems. Much of what was lost in the fire is work that will most likely be lost forever; it is possible that no other records of it exist elsewhere. The issue is that in Africa, knowledge is communally produced, shared, and owned. Western systems encourage the containment and individual ownership of knowledge. Traditionally, African knowledge is often shared in the sense that the process of producing and sharing this knowledge is done as a collective and is built into the day-to-day practices rather than being crafted as a separate experience in the way that mainstream Western education and research is done. 

Reimagining African epistemology 

There is an important method of passing down useful skills that you still find in African households even today. As kids, we often hated it, because it took us away from our games, watching TV, or general leisure time. As Zulus, we refer to it as ukuthunywa/thuma – the English translation of ‘running errands’ does not adequately represent what it means, but it will do. I want to argue that this practice has traditionally been an important epistemological tool for producing and sharing knowledge. As a child growing up in a family of farmers, for example, you are taught how to be a farmer through these ‘errands’. You might start off with small requests, such as having to watch while the grown-ups or older children perform certain tasks; as time goes on, you are expected to take on more and more responsibilities in the family trade or even in helping neighbours and other community members. Even when it came to storing and preserving knowledge, it was done in such a way that it was still easily accessible. It would be stored as rock art, songs and performances, everyday crafts, and practices. And contrary to Western beliefs that Africans never wrote or documented, for cultures such as the Egyptians and Ashanti, knowledge was even stored as written inscriptions. 

When we move away from ukuthunywa towards the more Western mainstream, some challenges arise. Students are almost exclusively taught in theoretical ways, separate from their everyday experiences, which makes it difficult to understand and value the knowledge and its place in society. Knowledge goes from being communally owned to being owned by an individual researcher or institution, which limits who has access to the information, who has the right to use it, and even limitations on how it can be used. At times, even the communities from which the knowledge originally came, are limited by copyright laws. I want to argue that if we had created African knowledge using African practices or possible methodologies such as ukuthnywa, the loss of the UCT African Studies section wouldn’t have felt so bad, because the knowledge would be actively existing in society and the ability to recreate and redocument it would feel within reach. 

The freeing of our indigenous knowledge systems requires that we shift from looking outwards for solutions. For example, instead of looking towards dangerous fossil fuel and expensive Western renewable energy solutions to address our ongoing energy crisis, why not look inward and invest in our own indigenous methods of creating cheaper, sustainable biogas using animal and food waste. Imagine if we did it in ways that empowers black rural women who are the custodians of this knowledge, so that while dealing with the energy issues, we simultaneously address poverty and environmental degradation. What would it look like if we continued to nurture and encourage this and similar practices? Could other important scientific innovations emerge from it? Could it grow to the level of informing global discourse? Could we finally be uhuru?

Mushrooms have so many medicinal applications that humans have a substance in hand to promote long healthy lives. And it is not only humans who benefit from these macrofungi growing mostly in dark spaces.

“The substrate applied for growing the mushrooms can be used as animal fodder. Keeping all the medicinal values intact, these are transferred to feed goats as a supplement to their daily diet,” said Prof Bennie Viljoen, researcher in the Department of Microbial, Biochemical and Food Biotechnology at the UFS.

Curiosity and a humble start
“The entire mushroom project started two years ago as a sideline of curiosity to grow edible gourmet mushrooms for my own consumption. I was also intrigued by a friend who ate these mushrooms in their dried form to support his immune system, claiming he never gets sick. The sideline quickly changed when we discovered the interesting world of mushrooms and postgraduate students became involved.

“Since these humble beginnings we have rapidly expanded with the financial help of the Technology Transfer Office to a small enterprise with zero waste,” said Prof Viljoen. The research group also has many collaborators in the industry with full support from a nutraceutical company, an animal feed company and a mushroom growers’ association.

Prof Viljoen and his team’s mushroom research has various aspects.

Growing the tastiest edible mushrooms possible
“We are growing gourmet mushrooms on agricultural waste under controlled environmental conditions to achieve the tastiest edible mushrooms possible. This group of mushrooms is comprised of the King, Pink, Golden, Grey, Blue and Brown Oysters. Other than the research results we have obtained, this part is mainly governed by the postgraduate students running it as a business with the intention to share in the profit from excess mushrooms because they lack research bursaries. The mushrooms are sold to restaurants and food markets at weekends,” said Prof Viljoen.

Natural alternative for the treatment of various ailments
“The second entity of research encompasses the growth and application of medicinal mushrooms. Throughout history, mushrooms have been used as a natural alternative for the treatment of various ailments. Nowadays, macrofungi are known to be a source of bioactive compounds of medicinal value. These include prevention or alleviation of heart disease, inhibition of platelet aggregation, reduction of blood glucose levels, reduction of blood cholesterol and the prevention or alleviation of infections caused by bacterial, viral, fungal and parasitic pathogens. All of these properties can be enjoyed by capsulation of liquid concentrates or dried powdered mushrooms, as we recently confirmed by trial efforts which are defined as mushroom nutriceuticals,” he said.

Their research focuses on six different medicinal genera, each with specific medicinal attributes:
1.    Maitake: the most dominant property exhibited by this specific mushroom is the reduction of blood pressure as well as cholesterol. Other medicinal properties include anticancer, antidiabetic and immunomodulating while it may also improve the health of HIV patients.
2.    The Turkey Tail mushroom is known for its activity against various tumours and viruses as well as its antioxidant properties.
3.    Shiitake mushrooms have antioxidant properties and are capable of lowering blood serum cholesterol (BSC). The mushroom produces a water-soluble polysaccharide, lentinan, considered to be responsible for anticancer, antimicrobial and antitumour properties.
4.    The Grey Oyster mushroom has medicinal properties such as anticholesterol, antidiabetic, antimicrobial, antioxidant, antitumour and immunomodulatory properties.
5.    Recently there has been an increased interest in the Lion’s Mane mushroom which contains nerve growth factors (NGF) and may be applied as a possible treatment of Alzheimer’s disease as this compound seems to have the ability to re-grow and rebuild myelin by stimulating neurons.
6.    Reishi mushrooms are considered to be the mushrooms with the most medicinal properties due to their enhancing health effects such as treatment of cancer, as well as increasing longevity, resistance and recovery from diseases.

Valuable entity for the agricultural sector
Another research focus is the bio-mushroom application phenome, to break down trees growing as encroaching plants. This research is potentially very valuable for the agricultural sector in the areas where Acacia is an encroaching problem. With this process, waste products are upgraded to a usable state. “It is therefore, possible to convert woody biomass with a low digestibility and limited availability of nutrients into high-quality animal fodder. By carefully selecting the right combination of fungus species to ferment agro-wastes, a whole host of advantages could become inherently part of the substrate. Mushrooms could become a biotechnological tool used to ‘inject’ the substrate that will be fed to animals with nutrition and/or medicine as the need and situation dictates,” said Prof Viljoen.
