This was the top pinned image of the month! I love it when the image contains the instructions too. I just ordered some lavender essential oil on Amazon (this one is the #1 best seller and has great reviews).
Psoriasis, eczema and dermatitis: Add 5 drops of lavender oil to 1 teaspoon of cold-pressed, extra virgin olive or coconut oil and apply to the area two or three times a day. (For large areas, you can mix larger amounts and store them in a tightly sealed, dark-colored glass container. You can buy brown glass bottles with an eye-dropper in sizes from ½ oz. to 2 ozs. that are ideal for this purpose.)
