+Cyclopia intermedia E. Mey. - Fabaceae - Kouga Honeybush-tea, honeybush (tea), **Honigbusch**
 Subshrub endemic between Port Elizabeth and the edge of the Langkloof in South Africa; leaves trifoliate, yellowish green; flowers bright yellow... The leaves of honeybush are commonly used to make herbal teas (healthy beverage) considered antioxidant.
 "There are dozens of species of honeybush tea found in the wild, of which mainly 4 or 5 are in widespread home or commercial use." \\

+"This species is experiencing a decline primarily due to the overharvesting of wild plants for the honeybush tea industry, constituting 85% of the commercially wild-harvested honeybush crop."

 "Plants from the genus Cyclopia are easily recognized by their sweetly, scented yellow, pea flowers. All 23 species of Cyclopia occur only in fynbos; from the Cederberg Mountains, southwards to the Cape Peninsula and eastwards to Port Elizabeth. Usually species are restricted to very small areas and then also to very specific habitats like high mountain peaks, marshy areas, shale bands and wet southern slopes. \\
-Honeybush tea [Cyclopia genistoides (L) R.Br.] was traditionally harvested only for home use, but has recently developed into an exciting, new commercial product as the demand has increased from tea-lovers around the world. Other species such as Cyclopia intermedia (bergtee) and Cyclopia subternata (vleitee) and Cyclopia sessiliflora (Heidelbergtee) are also harvested for tea.

 "The fermented leaves and stems of Cyclopia intermedia are used to brew Honeybush tea, a herbal tea indigenous to South Africa. The plant is also used to manufacture a sweet herbal infusion used for restorative properties such as soothing coughs and alleviating bronchial complaints including tuberculosis, pneumonia, and catarrh. It is claimed to have a low tannin content and no caffeine and contains various antioxidants. Continued investigations into the phenolic content of the leaves and stems of C. intermedia yielded [[https://en.wikipedia.org/wiki/Tyrosol|tyrosol]] and a methoxy analogue,... five glycosylated flavonols, two isoflavones, four flavanones, two isoflavones, and two flavones." \\

+More than 20 Cyclopia species of honeybush grow in the wild, but only Cyclopia intermedia, Cyclopia
+subternata, and Cyclopia genistoides, are currently commercially exploited to manufacture tea. Many of the terpenoids identified in C.intermedia and C.genistoides like α-terpineol, nerol, geraniol, linalool, linalool oxides, and eugenol, are known to have floral, sweet, sweet-woody, floral-woody, or spicy odors. "Sensory descriptive analysis showed that C. subternata differs from C. genistoides with respect to their sensory profile with C. subternata predominantly having a fruity sweet and apricot jam-like flavor note as opposed to C. genistoides having a vegetative sweet aroma." \\

+"The “characteristic” sensory profile of honeybush can be described as a combination of “sweet-associated”, “floral”, “fruity”, “woody” and “plant-like” aromas with a sweet taste and a slightly astringent mouthfeel... C. sessiliflora samples were associated with “green” aroma (“plant-like” and “green grass”), as well as a sour taste, and C. genistoides with “apricot jam” aroma and a slightly bitter taste. C. intermedia did not display a distinct profile as most positive attributes were perceived at moderate intensities. Although certain compounds can be linked to specific a roma notes, it is important to realize that aroma notes of different compounds can mask or suppress one another, and combinations of aroma compounds can produce new aroma characteristics." \\
