Pelargonium sidoides

Pelargonium sidoides

Also known as: African geranium, umckaloabo, kalwerbossie

A small herbaceous perennial pelargonium endemic to South Africa's grasslands and karoo edges, with deep-purple flowers and tuberous roots used in traditional Khoisan, Xhosa, and Sesotho medicine. The root extract is the basis of umckaloabo — a commercial respiratory-tract phytomedicine with substantial clinical evidence behind its use for bronchitis and acute respiratory infections.

Scientific

Pelargonium sidoides is in the family Geraniaceae. The plant is a low-growing rosette with velvety grey-green leaves and tall stems bearing very dark red-purple flowers. The medicinal part is the underground tuber.

Traditional medicine

Used in Khoisan and Xhosa traditions for respiratory conditions, tuberculosis, gastrointestinal upset, and wound healing. The Khoekhoegowab and Xhosa names — kalwerbossie, umckaloabo — carry the species into commercial European phytomedicine through the early 20th-century work of Charles Henry Stevens.

Modern phytomedicine

Standardized root extract is the active ingredient in umckaloabo and related preparations. Multiple clinical trials support efficacy for acute bronchitis and acute rhinosinusitis. South Africa’s commercial wild-harvesting of the species has raised conservation concern, which is part of why cultivated nursery supply (e.g., [[happy-by-nature]]) matters.
