With her condition, getting sick with a cold is terrible as her symptoms will get much worse. Between January 2013 and June 2013 (before we discovered therapeutic grade essential oils) she was on antibiotics 4 times, being sick for over 3 weeks each time, with her POTS symptoms becoming unbearable at times. Essential oils allow me to support her immune system. I use a protective essential oil blend (Wild Orange, Cinnamon, Clove, Eucalyptus, Rosemary) on the bottom of her feet. When she is around people that have a cold, she also takes it internally (additional oils black pepper and oregano) several times a day for an even greater boost. Her immune system has become so much better! To help her sleep better we use Lavender and Vetiver on the bottom of her feet. I also diffuse citrus oils and an uplifting blend of essential oils to create an atmosphere that helps reduce feelings of stress and will get her in good spirits. Her favorite essential oil is Wild Orange.
