Abstract: The present disclosure provides methods of increasing proliferation of adult salivary stem cells, methods of protecting adult salivary stem cells and improving salivary gland function. The methods include contacting adult salivary stem cells in vivo, in vitro, or ex vivo with a therapeutically effective amount of at least one isolated monoterpene and subjecting the adult salivary stem cells to radiation treatment. Increasing proliferation of adult salivary stem cells can be carried out to provide for an increase in the number of adult salivary stem cells and improve salivary gland function in an individual undergoing radiotherapy for head and neck cancer. The methods also include treating an individual with dry eye with a therapeutically effective amount of at least one isolated monoterpene.
