A species of geranium unique to South Africa, Pelargonium Sidoides also goes by the name Umckaloabo (or Umcka). Umckaloabo has been used to treat the common cold and flu virus – working to alleviate sinus inflammation congestion and sore throat, especially useful in cases of childhood infection that do not always respond well to antibiotic treatment, such as in Staph Aureus infection.
Umcka has also been shown to effectively treat bronchitis and other upper respiratory tract infections. It has been shown to significantly and effectively shorten the duration of acute-stage bacterial and viral infections.
Umcka's Key Health Benefits & Latest Research
Studies have shown that Umckaloabo has both antibacterial and anti-viral effects in the body, thanks in large part to two major constituents; coumarins and gallic acid.
Umckaloabo has been shown in studies to prevent both viruses and bacteria from attaching to the cells in the mucous membranes (sinuses, throat and respiratory tract), thereby preventing both bacteria and viruses from replicating. Studies have also confirmed that Umckaloabo activates macrophages within the body. These cells are responsible for engulfing and digesting pathogens, as well as recruiting other lymphocytes within the body to respond to pathogens.
When there is excess mucous congestion, usually thick and sticky, in the sinuses, throat and chest it is a breeding ground for bacteria and viruses to multiply. Umckaloabo is an expectorant herb, meaning that any infection that does manage to attach itself is ultimately expelled within this contaminated mucous. This further eliminates the potential for these infections to grow. Gallic acid has also been shown to be immunomodulatory, meaning that Umckaloabo helps to balance out the immune system, regulating the inflammatory process.
Tips For Taking Umcka Supplements
Umckaloabo can be found as a standalone supplement in liquid, both by the drop or in a syrup form, in various tasty flavours. When using drops of the standardized root extract, adults are recommended to take 30 drops 3 times per day. Children ages 6-12 are advised to take 20 drops, 3 times per day.
Umckaloabo can also be paired with other immune system herbs. Some complimenting herbs include:
- Elderberry
- Andrographis
- Echinacea
Umckaloabo works best when taken within 48 hours of the start of cold and or flu symptoms.
Potential Side Effects & Considerations
Talk to your healthcare professional before combining Umckaloabo with warfarin or other anticoagulant medications, although not universally the case, some individuals have found it to have blood thinning effects. Due to a lack of data, it is not advised during pregnancy or while breastfeeding.




Talk about flower power!Umcka seems to have numerous benefits. As someone with chronic sinusitis who responds poorly to traditional medications, I am going to have to learn more about Umcka! Anyawy, I had not heard of the term "expectorant" before this article. Thank you for explaining the definition, eg that for an expectorant herb, any infection that does manage to attach itself is ultimately expelled within this contaminated mucous. Being expectorant sounds like a really great benefit and I am so glad that I always learn something new though reading your articles :)
