I will have to check when I am home to see exactly what type we were given. There was one kind that you had to sit in hot water to heat it back to liquid form, as Jo said, the oils are a bit high and rich for some. I had such trouble getting my kids to take it, no matter what I mixed it in they seemed to detect it. One of my old boys was willing to take it off my finger, but he only tolerated limited doses; I don't know if he found it too rich or what.
There was another type, I think the one for birds, that we were given. It did not have to be heated, but despite the flavoring it still tasted kind of awful.
My vet (who isn't the best tbh) said they did not know if it would help or not, but it was all they could think to do for my little guy with the chronic resp issues, aside from traditional antibiotics. Perhaps I could have been more diligent in my attempts to get everyone to take this stuff, but given the cost and all the kids' general intolerance of it, we kind of gave up on it. If I want to try having them on immune boosters in the future, I'll probably do the echinacea thing, as they seem a lot more willing to have that.
