The essential oils I use really depend on what is needed at the moment. For example when my daughter was sick I gave her onguard which is an immunity booster, melalucea which is antifungal, antibacterial that helped get rid of her sore throat and congestion. I then applied Frankicense to help push it into her blood stream faster. However I am currently using more serenity to help my littles get to sleep better at night. So it really depends on what is going on in my life at the time. I have probably 40 that I keep at my house and about 13 that I keep in my classroom at all times. If you have any further questions please let me know and I will try to help out:)
