The hot syndrome refers to any feverish conditions during a pathological development, a sub-health phenomenon, and is a potential risk for human health. The metabonomics study on the hot syndrome may provide insight into understanding of its pathology and play a role in the prevention and treatment of its related diseases. In this paper, the rats were dosed with the hot syndrome prescription, ginseng and water. The corresponding urine samples were identified by rapid resolution liquid chromatography combined with quadrupole time-of-flight tandem mass spectrometry. More than 1,000 metabolic compounds from different urine samples could be further differentiated by principal component analysis. As a result, the rat body temperature and weight were recognized as the hot syndrome related factors. Some specific metabolites have been discovered as a pattern of the potential biomarkers for the hot syndrome. The results showed that ginseng cannot cause the hot syndrome in a reasonable dose, but the hot syndrome prescription can. It is suggested that ginseng cannot be used only as a tradition Chinese medicine but also as a nutrient. The work showed metabonomics method is a valuable tool in studying mechanism of the hot syndrome.
