I was going to use it for tea on those days I just can't breathe well. I get a few a year.
It does have side effects and can lower blood sugar erratically.
For eyes it's been used for conjunctivitis or anything that makes eyes goopy. Steep it in the hot water, then bring back to a boil for 30 seconds to kill off anything that was on the plant. Cover and cool. Most things like this will store a day or two in the fridge. Better to just make up small doses fresh.
I was looking up host plants for it. It's semi-parasitic. Grass, clover, and plantain are the preferred hosts. I have a ton of that.
