Goat's Rue and Ear Infections

I am searching for information regarding Goats Rue. I am told that it is very helpful in treating ear infections. Do you know anything about this?

The leaves and stems of Goat's Rue (Galega officinalis) lower blood sugar and are sometimes used to support diabetes therapy. Goat's Rue promotes milk flow in nursing mothers and is diuretic. I haven't heard of its use for ear infections.
Risk: grazing animals have been poisoned by Goat's Rue.
