Pelargonium sidoides

Pelargonium sidoides is a plant native to South Africa. Its common names include African geranium and South African geranium.

Description[edit]

African geranium forms a basal rosette of cordate leaves with a velvet texture and a few short trichomes on long petioles.[1] Its flowers have five dark red to nearly black petals, two of which are sometimes fused. It is often found in flower nearly year-round. It prefers to grow in grasslands with rocky soils. It can be difficult to distinguish from Pelargonium reniforme which grows in a similar area, but tends to have more kidney-shaped leaves.

Uses[edit]

A 2013 Cochrane review found limited to no evidence of benefit with Pelargonium sidoides root extract for the symptoms of acute bronchitis, the common cold and acute rhinosinusitis.[2] A summary of this review found that all studies were "from the same investigator (the manufacturer) and performed in the same region (Ukraine and Russia)."[2]

Root extract of Pelargonium sidoides may be sold as a dietary supplement or traditional medicine under various brand names, including Umckaloabo and Zucol, but there is limited high-quality clinical evidence it provides any benefit.[3]
