Maybe I am wrong- but I am using grapeseed oil-- and at other times, hexane free castor oil. Both oils have been giving me good results, and I am always clearing out mucous when using these two.

Maybe if I switched to Sesame or Sunflower, I'd even get better results! I will add those two oils on my future shopping list :-)

For now- I AM having good results with healthy gums, whiter teeth and mucous from deep in my throat being cleared out immediately after 15 minutes of oil swishing with castor or grapeseed oil in my mouth.
