South African Geranium

South African Geranium

What is it?

Umckaloabo, which is scientifically known as Pelargonium sidoides, is a medicinal plant that belongs to the Geranium family and originates from South Africa. So, it is also called South African Geranium. The name umckaloabo is a combination of two separate Zulu words, “umkhuhlane” that means cough and fever-related diseases, and “uhlabo” that means chest pain.

For centuries, native South Africans have been treating diarrhea, dysmenorrheal, liver disorders and respiratory diseases by using the roots of Pelargonium sidoides as a traditional medicine. Ever since 1983, German natives have been buying extracts of the root from local pharmacies without prescription for the treatment of respiratory tract, remedies for sinusitis and curing throat infections. Studies have proven that conditions like acute bronchitis, common cold and acute pharyngitis can be potentially treated using EPs 7630, which is an aqueous formulation of the Umckaloabo roots.

Note: Ever since 1983, in Germany, an extract of the roots of Pelargonium reniforme and Pelargonium sidoides has been marketed as “Umckaloabo.”
