I had some parsley to use up, so I made a tincture. I used a 1:2 ratio in 95% Everclear, putting it in a dark cabinet for 4 weeks, shaking every day or two.
I read that parsley is a diuretic so it's good for kidney stones & urinary tract infections. I also read that it helps remove toxins from the blood, reduces pulmonary congestion, and helps with bad breath.
