From what I’ve been learning and researching and asking people that sale Worm Oil they say worm oil is nothing but mineral oil with other ingredients add to make it Worm Oil the other ingredients I guess we will never know but this is what I have found out I took worm oil and mineral oil the 30 day test and basically saw no difference let them sit in the mineral oil for a month and no difference only difference one had a light like industrial oil smell when the other had no smell meaning that was the mineral oil.. and mineral oil is nothing but petroleum based.. mineral oil you’re buying in the store is considered food grade Hope this makes sense
