I would throw some salt in there.Swollen ankles, feet and legs (oedema)
Sometimes my feet get swollen, so I make this drink. It really makes me pee and takes away the swollen feet.
I don't know if it will work the same for you, but you could try it.
1 quart water
1 Tablespoon raw honey
2 Tablespoons apple cider vinegar
1 Tablespoon lemon juice, it can be a lemon juiced or the lemon juice concentrate.
If this recipe doesn't seem strong enough in flavor you can always add more of each to your quart.
I hardly ever make just one quart. I usually make a gallon and drink all of it in a day, plus water as well.
