I found a lump in my breast last week.  It wasn't hard, but it was clearly not "normal".  I immediately started putting frankincense on my breasts 2-3 times a day.  The lump is gone.  I'm going to keep up the frankincense for a while anyway.  I find I don't really need to know what it was or have undeniable proof that the frankincense worked.  I just use these oils when needed and good things keep happening with my body.
 
Grace and peace
