Research studies behind Camellix’s product development

Camellix’s product development has been supported by world-class research in three major areas which has led to novel and innovative discoveries.

I. Oral Health and Salivary Glands Function

The single most important factor for oral health is one’s own saliva.

  1. In molecular studies employing genomics and proteomics, the research team discovered specific genes that mediate salivary functions and can be modulated by natural compounds.
  2. Studies at the cellular level unveiled the signal transduction pathways involved in damage and repair mechanisms in the salivary gland.
  3. In vivo studies performed by the research team using animal models revealed that signals regulating activities of salivary gland cells can be interrupted by inflammation, medications, and free radicals generated by cancer therapies. More importantly, the investigators found that certain natural compounds can effectively protect salivary gland cells, especially the acinar cells that secret saliva.
  4. A clinical trial (Phase II) enrolling patients suffering from xerostomia and using the MighTeaFlow formula was completed successfully. The team discovered that this formula increased unstimulated salivary flow by 400%, an indication of restoring salivary gland function.

Clinical Trial Teams

Clinical trial for dry mouth funded by “Innovation in Oral Care Award” by IADR/GSK
The dry-mouth clinical trial team from the Georgia Regents University (formerly Medical College of Georgia), College of Dental Medicine, is using our MighTeaFlow formula lozenge to treat dry mouth.

Clockwise from left to right: Dr. Scott De Rossi, Dr. Kalu Ogbureke, Dr. Douglas Dickinson, Bob Wilson (dental student), Dr. Stephen Looney, Gina Hanafi (dental student), Dr. Stephen Hsu, and Dr. Jaisri Thoppay. For more information on each member, please visit the College of Dental Medicine’s website.
