South Africa is neglecting and overlooking the economic potential of Aloe ferox, forfeiting millions in potential revenue from this ‘green gold’. In doing so, the country is denying farmers and communities the chance to prosper from the land’s true bounty and is also undermining its biodiversity.

While South Africa harvests a mere 200 tons of Aloe ferox annually, its global competitors, such as Mexico, churn out a staggering 400 000 tons of Aloe vera, says Dr Gerard Verhoef, an intellectual property (IP) commercialisation specialist at Barnard Incorporated Attorneys. He gave an oral presentation titled IKS, the public domain and Biotrade during a session on Mountain People's Livelihoods at the second Southern African Mountain Conference (SAMC2025).

Researchers, policy makers, and practitioners from across Southern Africa and beyond came together from 17 to 20 March at the scenic Champagne Sports Resort in the central Maluti-Drakensberg for SAMC2025 themed ‘Overcoming Boundaries and Barriers’.

The next rooibos

SAMC2025, under the patronage of UNESCO and organised by the University of the Free State (UFS) Afromontane Research Unit (ARU) – in partnership with the African Mountain Research Foundation (AMRF) and the Global Mountain Safeguard Research Programme (GLOMOS) – delved into critical issues around mountain ecosystems, communities, governance, and transboundary cooperation.

Aloe ferox could be the next rooibos, which is successfully using its geographical indications (GI) status to unlock value throughout the biotrade value chain, Dr Verhoef said. Other South African plants that are also an underutilised asset with economic potential for the country, include honeybush, baobab, umsuzwane, rose geranium, imphepho, Cape chamomile, Kalahari melon, mafura, sour plum, and African ginger.

A GI consists of the name of the place of origin. It links a product to a specific geographical area, which indicates the origin of where the product is produced, processed, or prepared.

Overlooking the potential of Aloe ferox, which has been scientifically proven to contain double the amino acids and 20 times more antioxidants than its international cousin, Aloe vera, Dr Verhoef explains, South Africa is not only undermining its biodiversity but also the economy. Aloe ferox is most popularly used for its laxative effect (aloe bitters) and as a topical application to the skin, eyes, and mucous membranes. It is also used for many traditional uses as well as cosmetic purposes.

Time to capitalise

According to him, Aloe ferox remains an underutilised asset, relegated to niche markets and small-scale production due to regulatory constraints and the unwillingness to obtain access and benefit-sharing (ABC) permits needed to navigate obstacles in South Africa as well as Namibia, Botswana, Zimbabwe, and Mozambique.

“This is not just an agricultural oversight; it is a glaring economic misstep. It is high time that South Africa capitalises on its green gold, turning the tables on international competitors and finally giving Aloe ferox the global podium it deserves. This is not just an agricultural oversight; it is a glaring economic misstep.

Aloe ferox could be a flagship in the global wellness market, much like rooibos has become for tea. But until we embrace and promote our indigenous resources with the same vigour as we do foreign ones, our ‘green gold’ will remain just out of reach, a latent promise unfulfilled. It’s high time South Africa capitalise and turn the tables on international competitors, finally giving Aloe ferox the global podium it deserves,” said Dr Verhoef.

The path forward, he explains, requires a radical shift in how we view and value our native species. It demands a coalition of dedicated scientists, legal advisers, and farmers to advocate for more accommodating regulations and stronger market support. The pharmaceutical and cosmetic industries – major users of aloe products – must also be brought into the fold to help recalibrate the scales in favour of Aloe ferox. South Africa’s rich biodiversity is a national treasure, yet our approach to leveraging this wealth remains timid and fragmented.

Plant eco-physiologist finds effective solutions for crop optimisation

on a crop.

In a time characterised by society facing increasing population growth, food crises, and extreme climatic conditions such as drought, it is essential for farmers to integrate science with their work practices in order to optimise crops.

Role of photosynthesis and plant sap data

By knowing how to use photosynthesis and plant sap data for determining plant health, fast and effective solutions could be established for the optimisation of crops. This technique, which could help farmers utilise every bit of usable land effectively, is the focus of Marguerite Westcott’s PhD study. She is a junior lecturer and plant eco-physiologist in die Department of Plant Sciences at the University of the Free State.

Westcott uses this technique in her studies to prove that a newly-developed bio-stimulant stimulates plants in order to metabolise water and other nutrients better, yielding increased crops as a result.

Agricultural and mining sectors benefit from research

The greatest part of these projects focuses on the agricultural sector. Westcott and a colleague, Dr Gert Marais, are researching the physiology of pecan and citrus trees in order to optimise the growth of these crops, thus minimising disease through biological methods. Field trials are being conducted in actively-producing orchards in the Hartswater and Patensie areas in conjunction with the South African Pecan Nut Producers Association (SAPPA) amongst others.
 
The principles that Westcott applies in her research are also used in combination with the bio-stimulant in other studies on disturbed soil, such as mine-dump material, for establishing plants in areas where they would not grow normally. This is an economical way for both the agricultural and mining sectors to improve nutrient absorption, stimulate growth, and contribute to the sustainable utilisation of the soil.

The bio-stimulant contributes to the immunity of the plants.
It was tested in these pecan nut orchards (Hartswater).

Soil rehabilitation key aspect in research projects

“One of two things is happening in my research projects. Either the soil is rehabilitated to bring about the optimal growth of a plant, or the plants are used to rehabilitate the soil,” says Westcott.

Data surveys for her PhD studies began in 2015. “This will be a long-term project in which seasonal data will be collected continuously. The first set of complete field data, together with pot trial data, will be completed after the current crop harvest,” says Westcott.
