The transport of the Rooibos tea flavonoid aspalathin across the skin and the intestinal epithelium
The aqueous extract of rooibos has been used for more than three hundred years since its discovery by the indigenous people. Currently, rooibos is gaining popularity in the cosmetic industry and incorporation of rooibos extracts in topical cosmetic formulations has become a fashionable trend. Both topical and intestinal absorption of rooibos tea were investigated. The transport of aspalathin in the unfennented (green) rooibos aqueous extracts and aqueous solution of pure aspalathin were studied.
