This is one of my favorite methods of essential oil application for many acute conditions. It is very useful to allow essential oils to penetrate in a particular area of the body.
1) Mix 6 drops of essential oil(s) and 1 tablespoon salt in an empty bowl
2) Fill bowl with hot or cold water
3) Soak a piece of cloth, wring it out and cover the affected area
4) Repeat this process for 5 to 15 minutes, as needed.
For alternate compresses fill one bowl with very warm water, and the other one with iced water .
Here are some examples:
I mixed 3 drops of Grapefruit essential oil and 3 drops of Fennel essential oil with 1 tablespoon of regular salt and added to one bowl.
I created another mixture and added to the other bowl. One bowl was filled with hot water, the other one with iced water.
Fennel and Grapefruit are said to be litholytic which means they can dissolve stones. 
She was crying and initially would not even allow me to touch her. I applied one compress at a time, first the hot one, then the cold one for about 15 minutes.
The pain subsided, she literally woke up and went to the bathroom, expelled the stone and went to dance!
After the party I made a massage oil with orange, grapefruit, fennel and other detoxing oils, she applied it on her lower back and lower abdomen every day and never complained about a kidney stone again. I have recommended this method to many more friends and clients, they have always reported great results.
Aromandina’s recommendation: Detoxing Body Oil
MENSTRUAL CRAMPS – DYSMENORRHEAI’m one of those lucky women who hasn’t had a problem like that, but since I have worked in several spas I knew how my fellow coworkers felt on one of those days when they could not do a treatment out of the pain they were feeling. The essential oil that have worked very well for me are: Frankincense if the pain is excruciating. I remember that every time I applied these compresses I could feel their organs moving, almost like dancing, like stretching.
After 10 minutes, the pain was gone!
I then recommended them to use a massage oil with the same oils on a regular basis in order to not only address the symptoms but also to start regulating their bodies and hormonal system.
Aromandina’s recommendation for compresses: RADIARE Essential Oil, for massage oil: Woman’s Help Body Oil Memoria Blend, for daily application: Headache Begone Roll On
NOTE: Headaches and migraines are usually symptoms of many other conditions. This is just a method to help with the pain, but I highly recommend visiting a holistic practitioner who can help you get to the root of the causes.
FEVERSI always tell my students and clients that my son, in his 13 years of life has had only 5 infections. He doesn’t remember if he ever had a fever, and yes, his last fever was when he was 8 years old where he had an ear infection.
For fevers, think about cool oils like Spearmint and Lavender.
Apply cold compresses on the forehead, abdomen and feet.
OTHER USESMuscle Pain: peppermint, rosemary, lavender, marjoram, birch – cold or hot compresses
Stomach Cramps: ginger, cardamom, fennel, cinnamon
