Rooibos exports set a record in 2025 while the crop behind them did not grow. That gap is the entire story for anyone buying rooibos as a cosmetic active in 2026.
South African growers produced roughly 15,000 tons in 2025, down from about 17,000 tons in 2023, while exports passed the 10,000-ton mark for the first time and reached approximately 10,930 tons, up from around 5,900 tons a decade earlier, according to the South African Rooibos Council. Combined domestic and export demand sits near 18,000 tons a year. Japan alone took 33 percent of exports, about 3,606 tons.
Those are tea numbers. Cosmetic formulators are buying from the same fields, competing for a narrow grade of the same crop, and most of them have never seen the supply constraints written down.
The tea trade sets the ceiling
Rooibos (Aspalathus linearis) is a leguminous shrub harvested from the mountains and sandveld of South Africa’s Western and Northern Cape. Production has swung between roughly 13,000 and 25,000 tons a year over the past two decades, tracking rainfall and planting cycles rather than demand. The council’s chair, Dawie de Villiers, framed the industry position plainly in February: rooibos is not a volume-driven commodity, and its long-term value rests on quality, origin integrity and stewardship.
That is a defensible position for a tea industry. It is a constraint for a cosmetic buyer. Extract demand has to be met from a crop that is not expanding, is already running below combined demand, and prioritizes long-standing tea contracts in Japan, Germany, the Netherlands, the United Kingdom and France. The industry provides income to roughly 8,000 agricultural workers and sells into more than 50 countries. There is no large idle capacity waiting to absorb a new category.
Green rooibos is the grade cosmetics actually wants
The compound driving cosmetic interest is aspalathin, a C-glucosyl dihydrochalcone that occurs in commercially meaningful quantities only in Aspalathus linearis. It sits at the center of most rooibos antioxidant claims.
Aspalathin does not survive processing. Conventional red rooibos is oxidized, commonly called fermentation in the trade, and that step destroys as much as 90 percent of the aspalathin present in the fresh leaf, which corresponds to roughly a 70 percent drop in measured antioxidant activity. Unfermented green rooibos retains around ten times the aspalathin of the fermented product and can be standardized above 25 percent total polyphenols, according to South African extract house Zuplex.
The published work points the same way. A 2021 study in the journal Plants isolated linearthin, aspalathin and nothofagin from rooibos and tested them on human keratinocyte and melanocyte lines exposed to UVB. Low-concentration pretreatment preserved cell viability, reduced caspase 3 activation and lowered lipid peroxidation markers, with linearthin the strongest performer. The authors were explicit that green rooibos is the better starting material for isolating these compounds because fermentation depletes the dihydrochalcones, per the study.
For procurement this means a cosmetic-grade purchase order is not a rooibos order. It is a green rooibos order, made from material dried under controlled conditions to prevent oxidation, produced in far smaller volume than the red tea that funds the industry.
The extract market is small, and that is the point
Rooibos extracts move into four end uses: food and beverage, cosmetics and skin care, nutraceuticals, and pharmaceutical research. The green rooibos extract segment specifically is valued at about $141 million and is projected to reach roughly $227 million over five years at a 6.3 percent compound annual growth rate, according to processor Rooibos Ltd.
A market that size cannot outbid the tea trade for raw material, and it does not have to. It needs a small, reliable allocation of a specific grade. The risk is not price. The risk is that a cosmetic brand scales a hero product faster than its supplier can secure green leaf in a drought year.
Origin is a legal fact here, not a marketing line
Rooibos carries protection that very few botanicals have. The European Commission registered Rooibos and Red Bush as a Protected Designation of Origin on 31 May 2021, making it the first African food product on the EU register, according to SAnews. Under that registration the name cannot be applied to material that was not cultivated or wild-harvested in designated local municipalities of the Western and Northern Cape.
Two practical consequences follow. First, the common shorthand that rooibos grows only in the Cederberg is imprecise. The protected area spans designated municipalities across two provinces, not a single mountain range, and supplier origin claims should match the registration rather than the folklore. Second, the protection attaches to the name. Formulators writing “rooibos” on a carton sold in the EU are making an origin claim, and their supplier documentation has to support it.
The benefit-sharing levy is part of the landed cost
South Africa treats rooibos as an indigenous biological resource with recognized traditional knowledge holders. In May 2019 the industry concluded an access and benefit-sharing agreement with the Khoikhoi and San communities, described by Natural Justice as the first of its kind anywhere in its interpretation of the Nagoya Protocol, because it covers an entire industry rather than a single company.
The mechanism is a levy of 1.5 percent of the farm gate price, applied from 1 January 2019. The first payment cycle produced R12.2 million, per the rooibos council, and total distributions to traditional knowledge holders reached R42.7 million across 2019 to 2024, according to Bizcommunity’s coverage of the industry’s 2026 briefing.
Buyers should ask for the levy and permit documentation by name. A supplier who cannot show benefit-sharing compliance is a supplier whose material may not be lawfully placed on some markets, and that exposure travels downstream to the brand on the carton.
Climate is the supply variable to watch
Every structural risk in this crop reduces to water. The growing region is semi-arid, and irregular rainfall with rising temperatures has been pressuring yields for several seasons. The council named climate variability its most significant structural risk in February and said the season then underway could not yet be estimated reliably. No revised figure has been published since.
Longer term, modelling of rooibos under warming scenarios points to range contraction, with cultivation shifting upslope and to the southeast and marginal lowland sites dropping out first. The industry’s answer so far is breeding. In October the council, MaxIQ Space and the South African National Space Agency plan to send rooibos seed to the International Space Station, exposing it to microgravity and radiation to study stress-response genetics in service of more drought-tolerant varieties, per AgriNews. Any resulting cultivar is years from a commercial field.
What to specify when buying cosmetic-grade rooibos
The documentation gap between a tea contract and a cosmetic actives contract is where most sourcing failures start. A workable specification covers the following.
- Grade stated as green or unfermented rooibos, never simply “rooibos”, with the oxidation step excluded in writing.
- An aspalathin or total polyphenol assay with a defined minimum and a stated analytical method, on every lot.
- Harvest year and growing area named at municipality level, matching the terms of the protected designation.
- Benefit-sharing levy and bioprospecting permit documentation held by the exporter, provided on request.
- Microbial specification and a declared decontamination method, since dried botanicals for leave-on cosmetics face tighter limits than tea.
- Allocation terms rather than spot pricing, with volumes committed before the January to April harvest window rather than after it.
Rooibos is one of the better-governed botanicals a cosmetic formulator can source. It has a protected origin, an industry-wide benefit-sharing agreement, a council publishing production and export figures, and more than 700 peer-reviewed studies behind its compound profile. What it does not have is spare volume. Buyers who treat green rooibos like an ordinary catalog extract will find that out in the first dry season.
