As a healing oil for those winter-time, upper-respiratory infections, I recommend the use of eucalyptus oil.
Simply heat a pot of water to boil, and remove from heat....allow to simmer, add a few drops of oil, drape a towel over the head, close the eyes tight and breathe the steam. Opens the sinuses and clears congestion, *(but be warned....this will sting the eyes if they are left open).
The best thing about eucalyptus oil, for me, is that it's smell is reminiscent of the vicks vaporub that my mother used to put on me when I was a sick child. It makes me feel loved, comforted and safe. :tup:
