Five compounds (phytochemicals) were found that might contribute to the healthfulness of teeth and gums:
- oleanolic acid
- oleanolic aldehyde
- nic acid
- 5-(hydroxymethyl) -2furfural
Laboratory tests showed that phytochemical slowed or stopped the growth of two different types of bacteria commonly found in the mouth: Streptococcus mutans, which cause cavities, and Porphyromonas gingivalis, which causes gum disease; and prevented cavity-causing bacteria from sticking to surfaces.
