- In the past two decades, the links between bio-cultural diversity and the richness of plant species in South Africa have contributed to ongoing attempts to develop traditional medicines for use in the modern complementary and alternative medicines sector. Eventually this will aid in the discovery of new drug entities for pharmaceutical industries.
- African traditional medicines are divided into two streams. The first involves the informal trading of herbal remedies and medicinal plants sold by traditional healers or sangomas and bushdoctors. But there is also a more formal market in which medicinal plants like buchu and African potato extract are sold as over-the-counter drugs.

- It is estimated that 80% of the globe’s population relies on traditional medicines. In South Africa, studies show there is one traditional healer for every 700 to 1200 patients [however, find Essop, R. 2015 and Wilkinson, K. 2013 under heading 6 on these statistics]. The primary health care system is inaccessible to many and this drives people’s reliance on medical plants.
- Geo-climatic regions produce plants that are popular as traditional medicines. In the Western Cape, where fynbos (fine bush) dominates, leaf material is used by traditional healers from the KhoiSan culture. Elsewhere, in the Eastern Cape, KwaZulu-Natal and Gauteng, barks, roots and bulbs are all harvested from the wild for medicinal use. KwaZulu-Natal is also home to one of the largest medicinal markets in Africa.
- Many of the medicinal plants are harvested in the wild, some becoming very rare and facing extinction.
- The trade in traditional medicines was estimated at around R2.9 billion annually (Mander, Ntuli, Diederichs & Mavundla, 2007).
- Because cultivating medicinal plants ensures their availability, protects the ones in the wild and creates job opportunities, the intervention of cultivation technologies is supported by government and other role players.

Farming medicinal plants
Increases in market prices for certain medicinal plants have been linked to localised species extinctions and declining supplies of these plants. The declining supplies are directly attributed to over-harvesting of certain popular target species for medicinal use. This has resulted in researchers calling for the cultivation of indigenous medicinal plants as an intervention to address biodiversity and market sustainability issues. There is, however, much debate around the pro’s and con’s of medicinal plant cultivation. Concerns are largely focused on: (i) The potential loss of cultural and indigenous values associated with wild harvesting of medicinal plants; (ii) Potentially reduced production of secondary metabolites (the active ingredients in most medicinal plants) in farmed plants compared to wild stocks; and (iii) Genetic contamination of local species populations through cultivation with plants from alternative genetic stocks.
Cultivation trials and pilot projects conducted to date have shown that medicinal plant cultivation has good economic potential for supplying commercial-scale volumes of medicinal plants. Fast-growing species can be supplied in sufficient quantities to meet market demand within a few years. However, slow-growing trees, particularly forest trees, are unlikely to supply the quantities of medicinal bark demanded in the short-term; nor does the production of bark from these trees present an economically viable production system. The production of alternative tree-based products (such as tree leaves) has thus been investigated.
However, little is known about the effects of farming (cultivation) on the medicinal properties of plants. Cultivation aims to increase plant yields by improving growing conditions through addition of agro-chemicals and controlling the growing climate. Many Traditional Healers believe that cultivated plants treated with agro-chemicals (including fertilisers, pesticides and insecticides) do not have the same medicinal strength as wild plants. The active medicinal compounds that make medicinal plants so useful are mostly ‘secondary metabolites’ that are produced by the plant to protect it from attack by pathogens, insects and browsers or grazers. These secondary metabolites may also play a role in protecting the plant from extreme climatic conditions (e.g. frost). Plants that are stressed by these attacks or extreme climatic conditions tend to produce greater concentrations of secondary metabolites as a survival mechanism. Plants cultivated using agro-chemicals under controlled climatic conditions experience minimal stress and consequently produce less secondary metabolites. Chemical testing of cultivated plants has shown that the beliefs of many Traditional Healers with regards to cultivated plants having less medicinal strength than wild plants may, in fact, be true for many species. This has created the challenge of finding cultivation techniques that increase plant growth rates, but do not decrease the medicinal properties of the plants.
In a survey undertaken in South Africa in which farmed stocks of raw and stabilised (freeze-dried) rare / scarce medicinal plants were introduced into a medicinal market through traders and Traditional Healers, there was a general acceptance of the farmed plant materials by most Traditional Healers and their clients. Where the strength of medicinal compounds had been reduced through the farming techniques or processing technologies used to stabilise the products, the Traditional Healers simply prescribed higher dosages of the plants and plant products. This acceptance of farmed plant material is most likely attributable to the growing scarcity and associated cost of certain popular medicinal plants.
There is simply no other way to meet market demand for certain remedies that use scarce plants than to accept the farmed plant material in these cases. For species where availability or scarcity is less of an issue, Traditional Healers would probably be less accepting of farmed plant material. However, for commercial-scale production and supply of medicinal plants and products, farming is a necessity to sustainably achieve the volumes of plant material required.
Therefore, it is likely that medicinal plant farms are the reality for the future provision of both scarce and commercially sought-after medicinal plant species in southern Africa.

National strategy and government contacts
- Access to South Africa’s biodiversity is legally controlled by the Biodiversity Act (No. 10 of 2004). The Government Gazette No. 8831 of 8 February 2008 also applies, carrying the Commencement of Bio-Prospecting, Access and Benefit-Sharing Regulations, 2008.
- In line with the National Health Act, government has also developed Regulations governing the implementation of the Traditional Health Practitioners Act, 2007 (Act No 22 of 2007).
- The trade in indigenous medicinal plants is unregulated and so side-effects are not known or catalogued. After calls to monitor this, the Medicines and Related Substances Act was amended in 2009. It now stipulates that phytopharmaceuticals must undergo tests to prove their safety.
- In 2014 the Traditional Health Practitioners Act was passed to standardise and regulate the affairs of all traditional healers. In 2015 additional regulations were published to give effect to the act. Find a discussion on these at http://ewn.co.za/2016/01/22/OPINON-SA-and-regulating-traditional-healers-its-not-easy.
- Read the discussion “Comments on the Protection, Promotion, Development and Management of the Indigenous Knowledge Systems Bill” at www.golegal.co.za/iks-bill-indigenous-knowledge-systems/. The bill follows the Intellectual Property Laws Amendment Act, 2013.
The National Development Plan (NDP) includes in its strategy collaborating with traditional healers (page 321).
The Department of Science and Technology established the National Indigenous Knowledge Systems Office (NIKSO) as one of its Programmes. The aim of NIKSO is to protect and promote African indigenous knowledge systems (IKS). NIKSO is also viewed as the growth engine for IKS knowledge development and knowledge management. Investment in the harvesting of IK through documentation from oral sources, systematisation and development holds the potential of contributing to the scientific and technological solutions for the future challenges of poverty and diseases in South Africa. IKS will also preserve and affirm local communities by incorporating these communities into the knowledge economy. Visit www.dst.gov.za.
The Department of Environmental Affairs is the South African government authority responsible for the environment. Visit www.environment.gov.za.
The Department of Health‘s support for African traditional medicines research has included a R6 million grant channelled through the Medical Research Council for research into the safety, efficacy and quality of traditional medicines used as immune boosters by people living with HIV and AIDS. The department has a legislative framework to encourage the development of natural products for human health through the Medicines and Related Substances Act (Act 101of 1965). The Act seeks to regulate the use of complementary, alternative, African Traditional and other categories of medicines in South Africa to ensure quality, safety and efficacy. See www.health.gov.za.
