Eucalyptus is a wonderful herb that opens up the lungs and can help deepen your breath.
Eucalyptus creates more ease to breathe and clears blockages of mucus or phlegm. It is a wonderful aid if you are experiencing congestion.
Use eucalyptus essential oil on Lung 9 (located on the inner side crease of the wrist on thumb side) and run it in a diffuser at night while you sleep.
Hanging fresh eucalyptus in your shower is also beneficial.
