I get weird reactions to many drugs/substances so I would prefer not to take paste that has a lot of other stuff in it. The goo, the flavorings, probably preservative, etc.
I think they could be caused by having a lot of stored vitamin A. Many foods contain vitamin A supplements.
I never eat any pre-prepared foods, never eat out, cook everything from scratch, for decades. So I don’t get any vitamins other than what is in food and herbs.
I did get poisoned by diazanon years ago which pretty much wrecked my health in many ways, got allergies/sensitivities to many things after that. (By a neighbor, I didn’t use it.) Also inherited a proneness for it.
