Common Name: Honeybush Tea

General Information

Cyclopia intermedia is an erect, much-branched shrub
This species is one of the major sources of honeybush tea. It is collected in large quantities from the wild and is also sometimes cultivated. The tea is commonly drunk in S. Africa and is also becoming more popular on a global basis.

Cultivation Details

Cyclopia intermedia is native to the Mediterranean climate of southern S. Africa, where it experiences hot, dry summers and moister, mild winters. Whilst able to tolerate occasional light frosts, it is killed by hard frosts[].
Requires a sunny position, growing best in a well-drained sandy soil[]. Grows best in an acid soil, being able to succeed in a pH as low as 3.5[].
Plants are adapted to growing in areas where fires often occur naturally. Although top-killed by the fire, they generally resprout freely from the base[]. In cultivation, the plants can be pruned severely every few years to keep it tidy[].
The flowers have the aroma of honey, which attracts beetles that are responsible for most of the pollination[].
This species has a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[].

Edible Uses

A tea is made from the leaves and young stems[]. The tea has a distinct sweet taste and aroma. It is brewed in the same way as China tea (Camellia sinensis), except that simmering enhances the flavour. The tea is said to promote good health, to stimulate the appetite and also the milk flow of lactating mothers[]. A popular local drink and also traded internationally, the tea contains no caffeine and also has a much lower tannin content than the oriental teas (Camellia sinensis)[].
The leaves are often fermented to make the tea. The stems and leaves are chopped into small pieces, wet and then left in heaps where they ferment spontaneously, They may also be heated in an oven to about 60 - 70°c in order to enhance the process. After sufficient fermentation, the tea is spread out in the sun to dry and then sifted[].
To make 'green' honeybush tea, the fermentation process is skipped, resulting in a lighter-coloured tea that does not have the characteristic sweet flavour of the fermented tea. However, green honeybush tea has a higher antioxidant activity and is therefore popular with health-conscious consumers, and also has applications in cosmetics and functional foods.

Medicinal

The leaves and young shoots are anticholesterolemic, antioxidant, appetizer, expectorant, hypoglycaemic and restorative[, ]. A tea made from the leaves and young stems (and also sometimes the flowers) is used to treat coughs. The tea is also believed to be of use in the treatment of diabetes and menopausal symptoms, to reduce blood lipids and to increase the flow of milk in nursing mothers[].

The plant contains pinitol, a modified sugar similar to inositol. Pinitol has been shown to be expectorant and also appears to lower blood-sugar levels, making it of service in the treatment of diabetes[].
The plant also contains flavones, isoflavones, coumestans, luteolin, 4-hydroxycinnamic acid, polyphenols, and xanthones. These all have antioxidant properties and may help to lower blood lipid levels[].
The isoflavones and coumestans are also phytoestrogens and can be of help in the treatment of menopausal symptoms[].

Other Uses

A leaf extract of the plant is used in commercial cosmetic preparations as a humectant and skin conditioner[].

Propagation

Seed. Like many species within the family Fabaceae, once they have been dried for storage the seeds of this species develop a hard outer skin and will benefit from scarification before sowing in order to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing[].
Species in this genus grow in areas where fires commonly occur naturally, and the seeds are adapted to respond to the smoke of the fire, with many seeds germinating with the first rains after a fire. Burning a small amount of paper over the seed, and then sowing the ashes together with the seed, can improve germination rates (so long as the fire was not intense enough to damage the seed!).
The seed should be sown on a medium with good drainage and a low pH of 3.5 to 5. Germination usually takes place within two weeks[].

Tip cuttings root fairly easily, especially if rooting hormone is used[].
