Herbal medicine is widely used worldwide and is associated with side-effects such as skin eruptions. Herbal drugs are often produced by combining multiple crude drugs, mostly of plant origin. Determining which medicinal plants are associated with the herbal drugs that induce skin eruptions can therefore be difficult. This study investigated mRNA expression of several cytokines in pe- ripheral mononuclear cells (PBMCs) from two patients with herbal drug-induced skin eruptions; one reacted to

PBMCs (1×10 6 ) from the 2 patients were cultured for 24 h with the supernatant from the medicinal plants from KBG or senna in various concentrations, and a reverse transcription-polymerase chain reaction (RT-PCR) analysis was performed. A high mRNA level of interleukin (IL)-4 and IL-5 was detected in PBMCs stimulated by KBG and two of its components. Senna stimulated a high level of IL-4 and IL-5 mRNA levels in PBMCs from patient with senna-induced drug reaction.
