I work in an emergency room as a Registered Nurse. I have had allergies and terrible PMS my entire young adult life. Young Living oils have totally changed my life. I use lavender and peppermint for all seasonal allergies and was able to get off Claritin and Flonase. It is amazing how much it has helped me. I put it on neat a couple times a day. As for the really bad PMS with horrible cramping, I started Progessence Serum about 2 months ago and it has drastically changed my PMS symptoms. I have started using oils to treat all ailments. Lavender for burns worked great just like I'd never had a burn. My favorites are: Peppermint, Thieves (this one has the best smell and is great to keep infections away), Progessence Serum, Joy (smells like perfume and works wonders on your mood), Lavender, Valor, Panaway (takes care of any pains I've experienced, great for back ache, headache and tendinitis), and all citrus oils. It's actually hard to name my favorites because I love them all!!!
