Introduction
Kanna (Sceletium tortuosum) is a unique South African succulent with a history steeped in traditional use by the San and Khoikhoi peoples. Revered for its mood-enhancing and stress-relieving properties, Kanna has been used in various forms—chewed, brewed as tea, or smoked—to combat fatigue, reduce hunger, and enhance well-being during arduous hunting trips in the arid regions of Namaqualand and the Karoo (1, 3).
In recent years, the global wellness market has embraced Kanna, recognizing its potential to support mental health and cognitive function. Research highlights the plant’s active alkaloids, including mesembrine and mesembrenone, which act as serotonin reuptake inhibitors (SRIs) and phosphodiesterase-4 (PDE4) inhibitors, mechanisms that may explain its effectiveness in managing stress and anxiety (2, 3). These bioactive compounds have not only brought scientific validation to Kanna's traditional uses but have also spurred the development of standardized extracts such as Zembrin®, a product renowned for its consistent alkaloid profile and clinical efficacy (2, 3).
However, the rising demand for Kanna products presents challenges in ensuring quality and ethical sourcing. The variability in alkaloid concentrations due to environmental factors and cultivation methods makes it imperative to seek out reliable suppliers (4). Additionally, ethical sourcing is crucial to preserving the cultural heritage of Kanna while supporting the indigenous communities who have safeguarded this botanical treasure for centuries (1, 3).
This article explores the growing importance of quality assurance and ethical practices in the Kanna industry, providing insights into trusted suppliers and the benefits of choosing standardized, responsibly sourced products. By understanding these factors, consumers can make informed decisions to safely integrate this remarkable plant into their wellness routines.
The Importance of Quality in Kanna Supplements
When it comes to Kanna supplements, quality is not just a preference but a necessity. The effectiveness of Kanna relies heavily on its active alkaloid profile, which includes compounds like mesembrine, mesembrenone, and mesembrenol. These alkaloids are responsible for Kanna’s mood-enhancing, stress-relieving, and cognitive benefits, making it critical to choose products that standardize and quantify these active ingredients (2, 3).
Understanding Standardized Extracts
Two standout products in the Kanna market are Zembrin® and KannaEase™, both of which exemplify the importance of standardization and sustainability in delivering consistent therapeutic benefits.
Zembrin®
Zembrin® is a proprietary 2:1 hydroethanolic extract derived from the dried leaves and stems of Sceletium tortuosum. This standardized product is cultivated on Global Good Agricultural Practice (GAP) certified farms in South Africa, ensuring minimal pesticide use and rigorous testing for contaminants like heavy metals, aflatoxins, and microbiological hazards. The extracted material is processed under EU-GMP-certified facilities and spray-dried to achieve an alkaloid content of 0.35–0.45% by weight. Each batch of Zembrin® is tested to ensure the presence of mesembrenone and mesembrenol (≥60%) and mesembrine (<20%), guaranteeing a precise and effective profile (5).
KannaEase™
KannaEase™ is another premium extract of Sceletium tortuosum, designed to support mood enhancement, stress reduction, and cognitive function. Produced by Afrigetics, KannaEase™ adheres to stringent ethical and environmental standards, including compliance with the Nagoya Protocol to ensure equitable benefit-sharing with indigenous knowledge holders.
This fine, spray-dried powder is standardized to deliver >4mg of total alkaloids per gram, making it a highly potent option for various applications such as tablets, capsules, syrups, and gummies. A single kilogram of KannaEase™ yields up to 40,000 effective doses (25mg per dose), offering a cost-effective solution for manufacturers. Afrigetics emphasizes sustainability by actively cultivating Sceletium in the arid regions of the Cape Province, reducing the pressure on wild populations while maintaining a high-quality, ethically sourced product.
Why Standardization Matters
Inconsistent levels of active alkaloids in non-standardized Kanna products can lead to variable effects, undermining both safety and efficacy. Products like Zembrin® and KannaEase™ address this challenge through meticulous standardization, ensuring that each dose provides the desired therapeutic benefits without unexpected side effects (3, 4).
Commitment to Sustainability and Ethics
Both Zembrin® and KannaEase™ represent a commitment to sustainable and ethical practices. Afrigetics, the producer of KannaEase™, operates under a bio-prospecting license and follows FSSC22000 manufacturing standards. By cultivating Sceletium in controlled environments and collaborating with local communities, they ensure that their products are not only high-quality but also environmentally friendly and socially responsible (3).
Choosing the Right Product
Whether you’re seeking stress relief, cognitive enhancement, or mood support, selecting a trusted brand like Zembrin® or KannaEase™ ensures a safe and effective experience. These products set a benchmark for quality and ethics in the Kanna supplement industry, allowing consumers to enjoy the full spectrum of benefits this remarkable plant has to offer.
Ethical Sourcing and Partnerships in the Industry
The sourcing and commercialization of Kanna (Sceletium tortuosum) have brought significant attention to the importance of ethical practices in the natural products industry. Ethical sourcing not only preserves the cultural and biological heritage of this remarkable plant but also ensures that the communities who have nurtured this tradition for centuries are fairly compensated and involved in its global success.
The Framework of Ethical Sourcing
South Africa has implemented robust regulations to ensure the sustainable and ethical use of indigenous biological resources like Kanna. The National Environmental Management: Biodiversity Act (NEMBA) of 2004, aligned with the Nagoya Protocol, governs the conservation and sustainable use of biological diversity while ensuring the equitable sharing of benefits from bioprospecting activities (6). This legislation mandates benefit-sharing agreements (BSAs) and material transfer agreements (MTAs) for all stakeholders along the supply chain, from harvesters to processors and exporters.
NEMBA also recognizes indigenous knowledge as intellectual property, protected under the Indigenous Knowledge Systems Act of 2019. This legislation ensures that indigenous communities, such as the Khoi and San, receive fair recognition and benefits for their traditional knowledge of Kanna’s applications (6).
The Role of Afrigetics in Ethical Sourcing
Afrigetics, a South African company specializing in herbal products, exemplifies these ethical practices in its production of KannaEase™. This standardized extract of Sceletium tortuosum is produced under a bio-prospecting license in compliance with NEMBA. Afrigetics collaborates with local communities and supports sustainable cultivation practices to ensure the long-term availability of Kanna while honoring its cultural heritage. The company's efforts extend beyond regulatory compliance, fostering socio-economic development and environmental sustainability in the regions where Kanna is cultivated (6).
Challenges and Innovations in Ethical Sourcing
Despite these advancements, the implementation of ethical sourcing regulations remains complex. Ensuring compliance at every stage of the supply chain—harvesting, processing, and export—requires meticulous documentation, which can deter companies from adhering to these guidelines (6).
To address these challenges, companies like Afrigetics and Zembrin®’s producers actively invest in transparency and community partnerships. By supporting education, local employment, and sustainable farming practices, they are setting a standard for how the natural products industry can responsibly source and commercialize traditional medicinal plants (6).
Why Ethical Sourcing Matters
Ethical sourcing is not just a regulatory obligation; it is a commitment to preserving the cultural and ecological integrity of Kanna. Supporting companies that prioritize ethical practices allows consumers to contribute to a fairer global market while enjoying the benefits of high-quality, sustainably sourced products. As the demand for Kanna continues to grow, maintaining these standards will be crucial to ensuring its availability for future generations.
