Just some information on essential oils for your ibs that might help if you're not aware already.
I've used a mix of lavender 2 drops to 1 drop of peppermint oil which can be massaged into the lower abdomen in anti-clockwise circle (this is the way peristalsis or movement of the bowels works) for about 5-10mins .
Peppermint Oil This aromatic oil helps with general digestive symptoms, mostly because it has anti-spasmodic (soothing) properties. It can also ease complaints like gas and bloating, says Dr. Armstrong. Peppermint can be sold as oil or as a supplement that you take orally. If using peppermint as a supplement, Armstrong says to be sure you choose enteric-coated capsules for best absorption.
Basil Oil The essential oil derived from this delicious herb acts as a carminative, which means it can help ease gastric upset, potentially by calming intestinal spasms. Eating basil leaves or making basil tea may also have stomach-soothing benefits.
Turmeric Oil You may know and use this spice, often enjoyed in Indian dishes, but turmeric can also be used as an essential oil. The active ingredient in turmeric is curcumin, which has been shown to reduce inflammation, a key factor in ulcerative colitis. A report published in September 2011 in the Indian Journal of Pharmacology found that oil of turmeric offers significant anti-inflammatory properties.
And apparently patchouli can help in repairing the gut lining. I would think it would be ingested but would need to put into a gelatin capsule first.
I got the information from this website but I also have over 20 years knowledge of aromatherapy & massage & have taken courses in both.
