Is all propylene glycol the same???? I received the propylene glycol I ordered online and have some questions for you all. It says the following on the label: "Dosage: Cows, orally, 8 ounces twice daily for four days." "Indications: An aid in the treatment of bovine ketosis (Acetonemia) FOR ANIMAL USE ONLY" Do you guys think this will work for cigars? I assume propylene glycol is propylene glycol and it should be fine, just wanted to get everyone's opinion. And no, this is not a joke!!
