Calm down first step. It was the other day Tango was into the aloevera plant right. You would have seen effects by now. My Vixen pulls the leaves of any flowers that come into the house but never eats them. It is possible he never touched them. If you want to be on the safe side call the vet emergency number and have the vet call you back. They will advise as to what should be done. I think he is probably just fine if he isn't behaving any differently than before. Give yourself the peace of mind and call the emergency number. You can induce vomiting but call the vet first.
