TL;DR: South Africa is home to one of the six recognised plant kingdoms of the world, with over 20,000 species — many with documented medicinal properties. Indigenous plants like Cancerbush (Sutherlandia frutescens), Sceletium (Sceletium tortuosum), and Rooibos (Aspalathus linearis) have been used for centuries and are now backed by peer-reviewed research. Terupharma's mission is to make these plants — and the world's best adaptogens — accessible to every South African through alcohol-free, triple-extracted liquid sprays.
A Kingdom of Plants, Largely Forgotten
South Africa is home to the Cape Floristic Region — one of the six recognised plant kingdoms of the world, and the richest in terms of plant diversity relative to its size. With over 20,000 plant species, nearly a third of which are found nowhere else on earth, South Africa sits on one of the most extraordinary botanical treasuries in existence.
For generations, the people of this land knew it. Communities across Southern Africa developed deep, sophisticated knowledge of which plants healed, which plants strengthened, and which plants restored. This knowledge was passed down through families, communities, and healers — a living pharmacopoeia rooted in centuries of observation and experience.
Much of that knowledge is now at risk of being lost.
Why the Knowledge Is Fading
Modernisation, urbanisation, and the dominance of pharmaceutical medicine have all contributed to a generational disconnect from plant-based wellness. Many young South Africans have grown up without access to the botanical knowledge their grandparents carried naturally. The plants still grow — but fewer people know their names, their uses, or their power.
At Terupharma, we believe this is a loss worth reversing. Not out of nostalgia, but because the science increasingly supports what traditional knowledge has always held: these plants work.
Some of Africa's Most Remarkable Medicinal Plants
Cancerbush (Sutherlandia frutescens)
Perhaps Southern Africa's most celebrated medicinal plant, Cancerbush has been used across the region for immune support, stress resilience, and recovery from illness. It contains a unique combination of L-canavanine, pinitol, GABA, and antioxidant flavonoids that make it one of the continent's most potent native adaptogens.
A review published in the Journal of Ethnopharmacology (2007) documented Sutherlandia's widespread traditional use across Southern Africa and noted its significant immunomodulatory, anti-inflammatory, and adaptogenic properties. The authors concluded that the plant's phytochemical profile supports its traditional reputation as a broad-spectrum tonic.

Sceletium (Sceletium tortuosum) — Kanna
Used by the Khoikhoi and San peoples of Southern Africa for centuries, Sceletium is one of the world's most fascinating mood-supporting plants. It works by inhibiting the reuptake of serotonin and by interacting with PDE4 — mechanisms that support emotional balance, reduce anxiety, and promote a sense of calm and wellbeing. It was traditionally chewed, smoked, or used as snuff. Today, concentrated liquid extraction delivers its benefits far more efficiently.
A 2013 randomised controlled trial published in the Journal of Ethnopharmacology found that a standardised Sceletium extract (Zembrin®) significantly reduced anxiety and improved cognitive flexibility in healthy adults. The study confirmed the plant's dual mechanism of action — serotonin reuptake inhibition and PDE4 inhibition — making it unique among natural mood-support compounds.

Rooibos (Aspalathus linearis)
Known globally as a tea, Rooibos is far more than a beverage. Native to the Cederberg region of the Western Cape, it is extraordinarily rich in antioxidants — particularly aspalathin, which is unique to Rooibos and has demonstrated anti-diabetic, anti-inflammatory, and cardioprotective properties in research.
A 2019 review in Molecules summarised the growing body of evidence on Rooibos's bioactive compounds, noting that aspalathin and nothofagin show significant antioxidant, anti-inflammatory, and metabolic-protective effects. The authors highlighted Rooibos as an underutilised South African botanical with substantial therapeutic potential.

Buchu (Agathosma betulina)
One of South Africa's oldest medicinal exports, Buchu has been used by the Khoikhoi for centuries as a digestive tonic, anti-inflammatory, and urinary tract support. Its essential oils — particularly diosphenol — give it potent antimicrobial and diuretic properties. Buchu was officially listed in the British Pharmacopoeia in the 19th century, making it one of the first African plants to receive formal Western medical recognition.
And Beyond Africa's Borders
The Terupharma philosophy extends beyond South Africa's borders to embrace the best of what the earth's plant kingdoms offer globally. Several of the world's most studied adaptogens come from other indigenous traditions:
- Ashwagandha — the cornerstone of Ayurvedic medicine for over 3,000 years, used for stress resilience, hormonal balance, and vitality. A 2019 study in Medicine found that 240mg of standardised Ashwagandha extract significantly reduced cortisol levels and self-reported stress in adults over 60 days. (PubMed)
- Rhodiola — a high-altitude adaptogen from Siberia and Scandinavia, prized for combating fatigue and mental burnout. A 2009 randomised trial in Planta Medica found Rhodiola rosea extract significantly reduced fatigue in night-shift physicians. (PubMed)
- Eleuthero (Siberian Ginseng) — used in Russian and Chinese medicine for endurance, immune support, and cognitive performance
- Reishi (Ganoderma lucidum) — the mushroom of immortality, revered in East Asian medicine for immune modulation, stress resilience, and longevity. → Shop Terupharma Reishi Liquid Extract
- Tongkat Ali — a Southeast Asian root with a long history of use for hormonal balance, libido, and physical vitality
- Schisandra — the five-flavour berry of Chinese medicine, used for liver support, endurance, and mental sharpness

Frequently Asked Questions
What is the most powerful medicinal plant in South Africa?
Cancerbush (Sutherlandia frutescens) is widely regarded as Southern Africa's most potent medicinal plant. It has the broadest traditional use profile of any indigenous plant in the region and contains a unique combination of bioactive compounds — L-canavanine, pinitol, GABA, and flavonoids — that work synergistically as an adaptogen, immune modulator, and anti-inflammatory.
Are South African indigenous plants scientifically proven to work?
Yes — increasingly so. Plants like Sutherlandia frutescens, Sceletium tortuosum, and Aspalathus linearis (Rooibos) have been the subject of peer-reviewed research published in international journals. The science is still growing, but the evidence base for many Southern African medicinal plants is now substantial enough to support their traditional use.
What is the difference between a traditional remedy and a liquid extract?
Traditional remedies — teas, decoctions, poultices — are effective but inconsistent in potency. The concentration of active compounds varies depending on the plant material, preparation method, and storage. A triple-extracted liquid extract standardises the process: the same extraction method, the same concentration every time. You get the benefit of traditional plant wisdom with the consistency of a modern preparation.
Is it safe to use South African herbal extracts alongside conventional medicine?
Many people do, but it is important to consult your healthcare practitioner before combining herbal extracts with prescription medication. Some plants — particularly those with immune-modulating or hormonal effects — can interact with certain drugs. Your healthcare practitioner can advise based on your specific medication and health profile.
