Pelargonium sidoides is a medicinal plant native to South Africa. Its common names include Umckaloabo and South African Geranium. Root extract of Pelargonium sidoides is used as cold and flu medicine under various brand names including Kaloba, Umcka and Zucol.

Medicinal uses[edit]

Studies have suggested that extracts from the plant could be used in treating acute bronchitis,[1][2][3] acute non-GABHS tonsillopharyngitis (sore throat) in children,[4] and the common cold.[5]

A 2008 systematic review of these findings by the Cochrane Collaboration concluded that extracts of the plant might be effective in treating adults for acute rhinosinusitis and the common cold in adults, but they noted that this conclusion is not certain. They also wrote that it might be effective in relieving the symptoms of acute bronchitis in adults and children, and also the symptoms of sinusitis in adults.[6]

A 2009 systematic review concluded "There is encouraging evidence from currently available data that P. sidoides is effective compared to placebo for patients with acute bronchitis."[7]

A 2013 update summary of the Cochrane Collaboration however states they "considered the quality of the evidence low or very low for all major outcomes as there were few studies per disease entity, and all were from the same investigator (the manufacturer) and performed in the same region (Ukraine and Russia). Thus, in summary, there is limited evidence for the effectiveness of P. sidoides in the treatment of ARIs."[8]

It has been shown to be antimycobacterial with significant antibacterial properties against multi-resistant Staphylococcus aureus strains.[9] Gallic acid and its methyl ester present in large amounts in P. sidoides and in its active extracts, were identified as the prominent immunomodulatory principle.[10]

The Pelargonium sidoides extract EPs 7630 is an approved drug for the treatment of acute bronchitis in Germany. Determination of virus-induced cytopathogenic effects and virus titres revealed that EPs 7630 at concentrations up to 100 μg/ml interfered with replication of seasonal influenza A virus strains (H1N1, H3N2), respiratory syncytial virus, human coronavirus, parainfluenza virus, and coxsackie virus but did not affect replication of highly pathogenic avian influenza A virus (H5N1), adenovirus, or rhinovirus.[11]

"Pelargonium sidoides extract modulates the production of secretory immunoglobulin A in saliva, both interleukin-15 and interleukin-6 in serum, and interleukin-15 in the nasal mucosa. Secretory immunoglobulin A levels were increased, while levels of IL-15 and IL-6 were decreased. Based on this evidence, we suggest that this herbal medicine can exert a strong modulating influence on the immune response associated with the upper airway mucosa."[12]

A randomized, double-blind, placebo-controlled clinical trial of 200 patients concluded "EPs 7630 was shown to be efficacious and safe in the treatment of acute bronchitis in children and adolescents outside the strict indication for antibiotics with patients treated with EPs 7630 perceiving a more favorable course of the disease and a good tolerability as compared with placebo."[13]
