And, do you know what 200C means? My vet prescribed this for my bird 2x a day who eventually died.I had to go look at the container because thankfully I have only had to use it one time and that was almost two years ago. It is 30C. That is the strength you need. You dissolve it in a teaspoon of distilled water and drip it in the bird's mouth and nostrils, make sure they move their beak up and down so you know it's getting into their sinuses. You don't have to use the whole teaspoon, just a few drops..five or six, as I remember. Look at the OP's instructions. The hen we treated started out limping, later was unable to walk or even stand, she was rolling on her back. She was a pullet at the time. I have no idea what her problem was, but we treated her with the Hypericum, and as far as I know she has made a full recovery. She is a hen now, of course, and currently tryiing to produce a family.
