5. Green and Black Tea
Tea made from camellia Sinensis is a great afternoon pick-me-up thanks to its caffeine content. This very caffeine, most concentrated in green and black teas, has diuretic effects (25).

According to WebMD, “The fruit acids in hibiscus may work like a laxative.” (27) One particular species of hibiscus “roselle,” (Hibiscus sabdariffa) has diuretic, natriuretic, and potassium-sparing effects by influencing aldosterone activity (28).
To relieve temporary edema, here are a few other tricks you can use (29):
Keep moving: moving your muscles helps pump excess fluids to your circulatory system and kidneys.
Elevate: Hold the swollen part of your body above the level of your heart several times a day or while you sleep.
Massage the area of the excess fluid to stimulate blood flow and make it easier for your body to eliminate the excess fluid.
Compression: Your doctor may recommend wearing compression garments to prevent fluid from accumulating in your tissues.
Protection: Protect your edema-affected areas from injury and care for the skin around it, which may become itchy and cracked.
Now that you know the water retention causes above and how to treat the condition, you can finally get some relief. However, keep in mind that it’s always best to speak with your doctor to find out if edema is truly the reason for of your symptoms and to treat the underlying cause.
