Parsley, bladder disorders,
I feel sure that even Shakespeare would not be unhappy with the licence I've taken with one of his famous lines when it's pointed out that after men pass the age of 50, it is very common for them to experience the need to get up several times during the night to urinate..
This is, at the very least, an annoyance, and in the worst of cases symptomatic of some serious problems.
If you are experiencing this you need to know about parsley.
The paradox is that while parsley is a diuretic, which means that aids in the elimination of liquid from the body, drinking a small amount of a tea prepared boiling a handful of parsley (preferably fresh) in about a quart or liter of water, will cut down on the number of times you will feel the need to get up in the night to visit the bathroom.
I don't know where I first learned about this, but I've tried it, and I find that if I brew up about a liter of the tea and keep it in the fridge, drinking about 2 wine glasses of this a day, my need to get up in the night, is at least cut down by half, and I can often pass an entire night without making those little excursions.
The flavor is not particularly disagreeable, and you may even find it pleasant once you get used to it.
Parsley, in different forms has various other health benefits, but this use alone puts it near the top of my list of favorite vegetables.
