The name Ruikbossie (Afrikaans) means aromatic little bush and the leaves are quite strong smelling if crushed, although the smell isn't unpleasant, as many aromatic plants can be. This would go well in a pot pourri. Highly aromatic plants often contain volatile compounds that can be used in herbal medicine although I am not aware of any medicinal use for this particular plant.
These flowers are particularly difficult to photograph because they are so small, the slightest breeze makes the stems tremble and blurs the shot.
It's also very difficult to macro more than one flower because the different heights of the flowers ensure that some of them are going to be out of focus.
