This 2020 study in Brazil evaluated the bacteriological quality of six medicinal plants from community gardens, including Cymbopogon citratus and Aloysia citriodora. Analysis of cold extracts revealed bacterial contamination, with Plectranthus barbalus showing the highest aerobic mesophile count and Aloysia citriodora the highest coliform count at 45°C. However, the study concluded that heat treatment (boiling for teas) can significantly reduce or eliminate this bacteriological contamination, making the plants safe for consumption.
