Blue Bush

Pteronia incana, known across the Karoo as blue bush, is better known to farmers, ecologists, and rangeland scientists than to herbalists. Its silvery grey, resin-scented foliage has long been a familiar sight on South African sheep and goat farms, where its spread across a paddock was read by generations of stockmen as a quiet signal that the land had been grazed hard and needed rest. Reliable, well-documented records of it being used as a home remedy or medicinal herb are thin, so rather than guess at uses that were never clearly recorded, this entry focuses on what is confidently known: its identity, its ecology, and its character as a tough, good-looking garden shrub. In keeping with a commitment to accuracy over invention, no herbal preparations are offered for this species.
