Thank you this is very helpful!

Yes, there are contraindications and there are three things that should be done:
1) Check each E.O. for contraindications with each resident's meds.
2)Know the E.O. effects thoroughly.
3) Check allergy to the blend (not the E.O. neat) on the inside of the elbow.

There is no one E.O. fits all but typically the safest is Lavender(Lavandula angustifolia), not Lavendin ( Lavandula intermedia). The first has the most medicinal constituents (ie relaxation) whereas Lavandin is actually a stimulant.
