7. Onion
This traditional home remedy involves boiling a few onions in 4 cups of water with a little salt. Take 3 times daily for a few days to increase urine output and prevent kidney stones (13).
8. Lemon Juice
Lemons and other citrus fruits improve the elimination of excess fluid and waste.
These acidic fruits can wear down your tooth enamel, so dilute the lemon juice with warm water and drink it every morning (14).
9. Apple Cider Vinegar
Apple cider vinegar regulates sodium levels in blood pressure levels in the body (15). Since sodium causes water retention, this kind of vinegar is a simple solution to help you lose the extra weight.
For best results, take a teaspoon of vinegar in a glass of water twice a day. You can also add ¼-1/2 a cup of vinegar to your bath water.
10. Essential oils
Some essential oils stimulate the lymphatic system to enhance fluid drainage (16).
Add 20 drops of oils such as juniper, geranium, or cypress to your bath water and soak for 10 minutes.
For optimal edema relief, increase your intake of high-fiber and high-water foods like cucumber and watermelon. Make sure to get plenty of water too, since dehydration can actually worsen your condition. You should also exercise, get plenty of sleep, and avoid sugar, salt, and alcohol.
