The plant does so via particular nodules in its roots that create an oxygen-free setting, the place anaerobic micro organism are in a position to convert the nitrogen from air into kinds usable by dwelling organisms.

Rooibos is a nitrogen-fixing legume native to a small area of the West Cape Province of South Africa. Its manufacturing is proscribed to this space, and is weak to local weather change. Rooibos has quite a few constructive results on well being, that are solely starting to be completely studied and understood by science, however the preliminary proof suggests it protects towards radiation and will assist facilitate respiration as properly.
