Here is my tried and true flu fighter recipe using umhlonyana and other ingredients from the garden. It’s my own version of firecider (as I don’t have horeseradish).

Artemisia afra, also known as African wormwood or umhlonyana in isiZulu, is a highly aromatic shrub with a long history of traditional medicinal use in South Africa. Umhlonyana is commonly used for coughs, colds, influenza, sore throats, and asthma. The vapour from heated leaves is inhaled to clear nasal passages. It is also used to reduce fever. I use it to make a natural cold and flu remedy ahead of winter.

I am not a physician - this is not clinical advice.
