I have found an 8 oz bottle of patchouli EO and a 4 oz bottle of Clary Sage EO. They have been in dark brown bottles, in cool dry place, and completely unopened for about 15-16 years...... Think they've gone bad?
Patchouli EO is fantastically shelf stable, and often lasts a decade or more with little drop in potency. If you find that they smell "off" or you just don't want to risk it in a body product, they'd probably still be fine in a household cleaning product.
I got the patchouli from The Scent Shack, they seem to no longer be in business, but I looked up From Nature with Love and they are still around. Maybe I'll send them an email.
