You are on a road trip and someone comes down with earache, a rash, a sore throat or needs a little help with the daily, well, let’s just say that they need help.
And there is not a pharmacy in sight. Fear not. There is help at hand. As close as the side of the road.
South Africa has many medicinal plants – 3 000 species are used as medicine. In fact, many of the plants that surround us are used in primary health care throughout the country…
South Africa has well over 30 000 species of what science calls ‘higher plants’ (not mosses, liverworts or lichens; in other words plants with roots, seeds or flowers).
The Cape Floral Kingdom alone has almost 9 000 species and a diversity that rivals tropical rainforests in terms of richness in species.
Here are 10 wild South African plants for your first-aid kit when travelling. They form an emergency stop-gap for common gripes and ailments…
