Ever looked at that sticky, forgotten bottle of essential oil in your cabinet and wondered if it’s still okay to use? Let’s talk about the “Rancidity Clock” and why it matters.
Essential oils aren’t immortal. Once that cap is cracked, the clock starts. Oxidation turns botanicals into potent skin and respiratory irritants. If a bottle has that gummy residue like the one in this photo, it’s officially past its prime. 🕒
For our feline friends, this is a major deal. Cats lack the specific liver enzymes needed to process many of these compounds. What smells like a relaxing spa day to an adult can be an overwhelming load for a cat or a respiratory irritant for small children.
Scent is wonderful, but safety comes first. If it's sticky, gunky, or smells "off," it’s time to retire that bottle. 🌿
