Epigenomics is the study of epigenetic changes in gene expression that occur without commensurate changes in DNA base pair sequences; these changes may be transmissible to subsequent generations. Recent research in the emerging field of Epigenomics strongly supports the probabilities of therapeutic transgenerational herbalism. Epigenomics is developing in response to research showing very convincingly that many cancers are initiated and controlled by transmissible extrachromosomal mechanisms.
