Introduction
In general, fennel can to some extent help alleviate edema. However, the effect of fennel in reducing edema is relatively mild and cannot replace treatments targeting the underlying cause. Excessive consumption may, due to its irritant properties, adversely affect gastrointestinal or kidney function, thereby impairing fluid metabolism. Effective management of edema requires identifying the underlying cause, adjusting diet, and undergoing appropriate medical treatment when necessary.
In general, fennel can assist in alleviating edema to a certain extent. The detailed explanation is as follows:
Fennel contains volatile oil components that can promote blood circulation, accelerate blood flow, help improve local blood stasis, and reduce edema caused by poor circulation. Its diuretic effect can promote urine production in the kidneys, increase urine output, aid in the removal of excess water from the body, and thereby relieve edema symptoms. Additionally, fennel is warm in nature and can regulate qi and promote water movement, assisting in alleviating edema caused by stagnation of qi and fluid retention by improving the body's water metabolism.
The effect of fennel in reducing edema is relatively mild and cannot replace treatments targeting the underlying cause. Excessive consumption may irritate the gastrointestinal tract or impair kidney function due to its stimulating properties, thus negatively affecting water metabolism. To reduce edema, it is important to identify the underlying cause, adjust diet, and apply necessary standardized treatments. Fennel can be used as a complementary dietary ingredient alongside other diuretic foods. Individuals with impaired kidney function should limit their intake of fennel to avoid increasing the burden on the kidneys due to its diuretic effect.
