T author, from Imperial College London and Great Ormond Street Hospital, said: "This journey, which reflects the artemisinin of the Qinghao herb, may so far reveal another source of potent anti-infective treatment."  "Like the use of Qinghao, many traditional cultures prescribe a hot broth to treat fever, and each has attributed miraculous healing powers, such as Jewish grandmother's chicken soup. There really is some evidence that these broths really contain antibiotic properties. "
The recipes for vegetarian, chicken and beef-based broths varied, with no particular ingredient common to those who displayed the strongest antimalarial activity.
A red cabbage soup was among those who showed success, showing that chicken was not the only broth that appeared to have medicinal properties, researchers said.
The active ingredients in the bullies studied have not yet been identified and tested in clinical trials, researchers said.
They said it was also a successful exercise to teach children about the relationships between herbal remedies, traditional medicine and evidence-based drug discovery.
They said: "At a time when there is a resurgence voice against evidence-based medicine, such exercises are of great importance to educate the next generation on how new drugs are discovered, how they can work and how unused resources are still in the fight against global disease of importance. "
The results are published in the Archives of Disease in Childhood.
