title: Bamboo charcoal inhibits growth of HeLa cells in vitro.
abstract: The purpose of this work was to investigate the far infrared spectral characteristics of bamboo charcoal powder and its effect on cancer cells for use in the dental field. To analyze the effects of the powder, HeLa and WI-38 cells were used and then assessed by cell adhesion assay and WST-1 assay. The powder emitted far infrared rays at wavelengths between 4 to 16 microm. The multiplication rate of WI-38 cells showed no significant differences between the conventional culture (control group) and culture on the powder (FIR group). However, at six days after incubation, HeLa cells of FIR group had a significantly lower multiplication rate compared with the control group. Based on the far infrared rays emitted in this study, bamboo charcoal powder proved to be a promising dental filler material for cancer prevention.
