Does my cat have antifreeze poisoning? Is Herbal Tea safe for a cat? Please Respond Soon!?

One pupil is more dilated than the other and one is a bit constricted, This usually straightens itself out in about 5 minutes and her pupils are the same size again. In addition, the corner membrane is closing when her eyes are not closed. We saw her walking in from the garage 2 days ago liking her lips. Would it be safe to give her celestial seasonings (Trademark) Detox A.M Herbal Tea with NO caffeine? The good news on the other hand is that right now she is running around the house playing with her toys and jumping about and meowing, just as she always does. We have already called the vet and gotten all the info we need, however the only place thats open right now is the emergency clinic 30 miles away and the cost of that place is triple what a normal vet look over would be. So we are gonna wait until morning to take her to the vet?
