Oedema caused by kidneys’ imbalance – use fresh or dried urtica leafs, it is suggested not to boil the herbals' leafs rather, pour boiled water upon it and waits until it is almost cold. Use it regularly, 2-3 cups a day.
Oedema caused by heart and lungs’ imbalance – use fresh parsley, 2-3 cups a day.
If you’re not sure about the reason for an Oedema you can mix them together; it has some additional healing affects that can improve the situation.
Note: most of the time I suggest that some Stivia leaf will be added to give some sweetness to the tea and also dandelion leafs to improve the liver’s function and stomach ulcers.
