Sometimes the air conditioning units in hotels just make my nose stuffy. That is when I reach for RC, Young Living essential oil. RC is a blend of oils known to help with allergies, sinus issues, and colds. Basically, RC stands for Respiratory Conditions. This blend of eucalyptus, myrtle, marjoram, and pine (among others) is the best oil to carry while traveling because it not only helps calm the muscles around the sinuses, it helps to open up the airways, a must for sleeping at night. I say it acts much like the commercial chest rubs without the petroleum oils that seep into our systems. The scent is much lighter too. Diffuse and apply to the chest and back for the best benefit. This oil can be applied to the bottoms of the feet of younger folks or added to a bowl of steaming water. Place a towel over the head and inhale for sinus relief.
