Gut health is so important...but something that goes along with that, and not discussed as frequently, is your stomach lining and tissue. If there's a chance that you've damaged either of those, Celery Seed essential oil can help to calm and soothe them.
You can take 2-3 drops in a veggie cap every morning and night, for support. If you'd like to enhance the benefits, I recommend adding 1-2 drops of each of these oils to that veggie cap: Turmeric, Ginger and Cardamom. Do this as often as needed.
