This duo includes 2 of my favorites.
Lavender and Eucalyptus.
Lavender is universally known for its calming effects.
Rub a drop on your feet to calm and relax.
Place a drop of lavender on your palms, rub on to your pillow case to help aid sleep.
Drop lavender on a cut to help stop bleeding, cleanse a wound and kill bacteria.
Put a drop of lavender oil on a bug bite or bee sting to help stop itching and reduce swelling.
Eucalyptus aids to open the lungs and encourages breathing.
Helps clears clogged nasal passages and bronchial congestion making eucalyptus one of the best known cold remedies.
I put a couple drops in my shower every morning and enjoy its clearing benefits.
