Often referred to as "umcka," pelargonium is an herbal remedy thought to treat coughs and colds. Long used in traditional South African medicine, pelargonium has been found to knock out viruses and stimulate the immune system in a number of test-tube studies.
While relatively few clinical trials have tested the cold-fighting effects of pelargonium, there's some evidence that using liquid preparations of the herb may help ease cold severity and shorten the duration of sickness. In addition, several studies suggest that pelargonium may help relieve bronchitis.
If you're looking for a natural cold remedy, research shows that herbs like echinacea and astragalus may also provide cold relief. Getting plenty of sleep, gargling with warm salt water, and drinking lots of water and tea can help soothe your symptoms as well, according to the National Institutes of Health.
