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.

Childhood obesity should be curbed early

Serious intervention by parents is required to deal

If your child is overweight when they start school at the age of six, unless you do something about it at that point, the indications are they are going to be overweight teenagers and obese adults. This is according to University of the Free State’s Prof Louise van den Berg.

Evidence has shown that overweight children and teenagers have a greater risk of developing lifestyle diseases such as type 2 diabetes, hypertension and cardiovascular disease later in life, and dying prematurely.

Obesity is a global pandemic rapidly spreading among adults and children, in developed and developing countries alike.

Dr Van den Berg worked with Keagan Di Ascenzo, Maryke Ferreira, Monja-Marie Kok, Anneke Lauwrens, all PhD students with the Department of Nutrition and Dietetics, to conduct the study. Their research found that children who are overweight by the time they turn six should be screened for weight problems.

Why six-year-olds?
Children who are overweight between the ages of two and five are five times more likely to be overweight when they are 12. There are two periods in a normal life cycle when the body makes new fat cells. The first is in the uterus and the second is around the age of six. The second phase lasts from the age of six to puberty.

The study assessed the prevalence of obesity in six-year-olds as part of a campaign in South Africa to raise awareness of the problem among parents and educators.

A total of 99 children were chosen from seven schools in Mangaung, the capital city of Free State. The schools were chosen from quintile four and five schools, which when measured by their own resources and economic circumstances, are well resourced and serve largely middle-class and wealthy communities.

The children’s weight, height and waist circumference were measured and used to calculate a body mass index score and waist-to-height ratio. Both these figures are good predictors for future lifestyle disease risks such as type 2 diabetes, hypertension and cardiovascular disease. A person with a good waist-to-height ratio can wrap a piece of string equal to their height around their waist at least twice.

When the children had a higher body mass index, they also had an increased waist to height ratio. The study found one in four children from the schools surveyed were overweight when they started primary school.

Nipping the fat in the bud
Although there are many factors that play a role in preventing childhood obesity, parents’ perceptions of their children’s weight play an important role. A recent study found that more than 50% of parents underestimate the weight of their obese children. These parents remain unaware of the risks their children face and are not motivated to take any action.

At least half of the parents whose children are overweight struggle to recognise their children’s weight problems fearing that they will be labelled or stigmatised. By the time they turn six overweight children should be referred to dieticians and nutritionists who are qualified to guide their parents in getting them to eat well and be more physically active at pre-primary and primary school.

The high prevalence of weight problems among six-year-olds found in this study is an urgent call to healthcare professionals to step up and empower parents, educators and children with the necessary skills for healthy dietary practices and adequate physical activity.
