“Essential oil of thyme at…3% had consistent antibacterial activity against the 3 mastitis-causing pathogens tested. (Staph. aureus, Staph. chromogenes, and Strep. uberis)” K. A. Mullen, et. al An in-vitro assessment of the antibacterial activity of plant-derived oils. Journal of Dairy Science 2014 Sep; 97(9):5587-91.

“Using thymol as a marker, Phyto-Mast® was detectable and quantifiable in plasma beginning with the 15-minute post-treatment sample, but was no longer detectable in the 4-hour post-treatment sample. Thymol residues were only detected in the 12-hour post-treatment milk sample. An inflammatory response was not evident following phytoceutical administration.” C.S.
