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.

UFS scientists involved in groundbreaking research to protect rhino horns

Scientists at the University of the Free State (UFS) are involved in a research study that will help to trace the source of any southern white rhino product to a specific geographic location.

This is an initiative of the National Zoological Gardens of South Africa (NZG).

Prof. Paul Grobler, who is heading the project in the Department of Genetics at the UFS, said that the research might even allow the identification of the individual animal from which a product was derived. This would allow law enforcement agencies not only to determine with certainty whether rhino horn, traded illegally on the international black market, had its origin in South Africa, but also from which region of South Africa the product came.

This additional knowledge is expected to have a major impact on the illicit trade in rhino horn and provide a potent legal club to get at rhino horn smugglers and traders.

The full research team consists of Prof. Grobler; Christiaan Labuschagne, a Ph.D. student at the UFS; Prof. Antoinette Kotze from the NZG, who is also an affiliated professor at the UFS; and Dr Desire Dalton, also from the NZG.

The team’s research involves the identification of small differences in the genetic code among white rhino populations in different regions of South Africa. The genetic code of every species is unique, and is composed of a sequence of the four nucleotide bases G, A, T and C that are inherited from one generation to the next. When one nucleotide base is changed or mutated in an individual, this mutated base is also inherited by the individual's progeny.

If, after many generations, this changed base is present in at least 1% of the individuals of a group, it is described as a single nucleotide polymorphism (SNP), pronounced "snip". Breeding populations that are geographically and reproductively isolated often contain different patterns of such SNPs, which act as a unique genetic signature for each population.

The team is assembling a detailed list of all SNPs found in white rhinos from different regions in South Africa. The work is done in collaboration with the Pretoria-based company, Inqaba Biotech, who is performing the nucleotide sequencing that is required for the identification of the SNPs.

Financial support for the project is provided by the Advanced Biomolecular Research cluster at the UFS.

The southern white rhino was once thought to be extinct, but in a conservation success story the species was boosted from an initial population of about 100 individuals located in KwaZulu-Natal at the end of the 19th century, to the present population of about 15 000 individuals. The southern white rhino is still, however, listed as “near threatened” by the World Wildlife Fund (WWF).
