Health benefits of green rooibos tea

Where does green rooibos tea come from?


When it comes to rooibos, people tend to be more familiar with red rooibos or ‘redbush’. However from the same plant as red rooibos you can also get green rooibos. Both are from the Apalathus Linearis plant, but undergo differential processing to achieve the red or green version of rooibos tea. Red rooibos comes through the oxidation of the leaves which occurs if they are simply left exposed to air, turning them a deep redish brown colour. However, for green rooibos this process is prevented and the leaves are stopped from oxidising by instead quickly drying the leaves after harvesting them. This allows them to retain the distinct green colour.


How is it different from green tea?


The process for green tea production is the same as green rooibos. This involves quickly drying the leaves after they have been harvested to prevent them from oxidizing and maintaining the green colour. However a fundamental difference is that green rooibos comes from Apalathus Linearis plant, whereas green tea comes from Camellia Sinensis plant. Further, the rooibos plant does not contain any caffeine so green rooibos maintains a naturally caffeine free status. This makes green rooibos tea an excellent choice to be sure you will give yourself the best chance of a good nights sleep.


What are the health benefits of green rooibos tea?


Many people are aware that green tea has higher benefits than black tea and decaf tea alternatives. It is much the same with rooibos tea. The minimal processing used for green rooibos compared to red rooibos means that the leaves preserve an even greater amount of antioxidants. Importantly, two antioxidants; aspalathin and nothofagin are abundant in green rooibos (1). Aspalathin has been suggested to have the potential to improve lipid and glucose metabolism (2) which is helpful for obese or diabetic individuals (3, 4). Further a study where a number of adults consumed 6 cups of rooibos tea everyday found that compared to the control period, they had an improved lipid profile which is relevant to heart disease and the development of cardiovascular disease(5).


Also similarly to red rooibos, green rooibos is very low in tannins which are normally the reason that an over-brewed cup of tea tastes bitter. Therefore you can brew your loose leaf rooibos tea for as long as you like and it will not become bitter, but rather maintain a delicate and light flavour.


So, do you think you will switch and try our delicious green rooibos tea?
