Rooibos (Red Bush)

(Aspalathus linearis)

 

Background:

Red bush tea comes from the leaves of the Rooibos shrub which has needle-like leaves and is a member of the legume, or pea, family and native to the mountain slopes of western Cape Province, South Africa.1 The leaves are cut and aerated and used to make a tisane called Rooibos or red bush tea.

Red bush tea is caffeine free, low in tannin, high in vitamin C and bursting with antioxidants and other healthful plant compounds. It has been popular in southern Africa for generations and is now enjoyed around the world. Rooibos is brewed in the same manner as black tea and can be drunk with milk and sugar to taste, or with a slice of lemon and sweetened with honey.

 

Health properties:

Traditionally red bush tea has been used to relieve infant colic, allergies, asthma and dermatological problems.2 Laboratory studies have shown it has potent antioxidant, immune-modulating and anti-cancer effects.3,4,5

A 2011 study confirmed that a high intake of rooibos tea results in significant reductions in cardiovascular risk factors such as lipid peroxidation, LDL cholesterol, triglycerides, and an increase in heart-healthy HDL cholesterol levels compared with the study control group.6

Emerging data suggests red bush may help nervous tension, allergies and digestive problems.Rooibos tea has also been shown to inhibit in vitro activity of xanthine oxidase, an enzyme which could limit uric acid production and aid in treatment of gout.8
