I tried dripping it off their nose after drawing it up in a syringe (without the needle) but they just sat there letting it run off their chins! SO, my daughter would wrap the dragon in a washcloth just under the neck to secure the front legs & body. She'd hold the dragon upright, as if it were standing on it's back legs like a human does, then by gently pulling on the beard with one hand, the dragon will open it's mouth and I kinda slowly squirt the tea in their mouth from the syringe in my other hand while still holding onto the beard. With the dragon in the upright position, the tea will go down the throat into the right place. I had no luck with trying to give it with the dragon on a table, in a horizontal position.
Your partner will have to be good at keeping them from squirming once they start feeling better, it's not too much of a challange when they feel bad.
As far as the dose goes, I believe it was B22 who said that he gives 1cc of the tea per each 100 grams of the dragons weight, 1/2cc for a 50 gram dragon, 2cc for a 100 gram dragon, etc. That is the formula I used since none of them would actually drink it, some dragons will drink it on their own from what I hear, but not mine.
I would give it once daily and was thrilled with my dragons improvement on the 5th and 7th days of giving it.
Please feel free to ask anymore questions, no problem
