Nothing in there that I would consider effective against parasites. Unless you have a fecal float test done before and after use, to confirm efficacy, I wouldn't count on it working. Not seeing worms in droppings doesn't mean they are gone. I tried herbal stuff many years ago, I found it completely ineffective as a treatment, had sick and dead birds. There may be some benefit as a preventative, but that is not proven anywhere, so without consistent testing, who knows. I would use a proven medication if I know I'm actually treating a worm load.
