[Hinews] Sitting or standing all day often leaves legs heavy and swollen. While many dismiss this as simple fatigue, edema may indicate underlying issues such as poor fluid regulation, excessive sodium intake, or impaired kidney or liver function. Persistent swelling can interfere with blood pressure control and glucose metabolism, underscoring the importance of proactive management.
In Korea, traditional remedies like herbal teas have long been used to alleviate edema. Among them, corn silk tea and pumpkin tea stand out, cherished for centuries and now backed by scientific research for their health benefits beyond folklore.
Corn Silk Tea: A Potent Diuretic with Cardiovascular Benefits
Corn silk tea, brewed from the golden threads surrounding corn cobs, has earned its reputation as a go-to remedy for edema. Rich in polyphenols, flavonoids, saponins, and alkaloids, it promotes waste elimination and diuresis. Its high potassium content helps promote sodium excretion through the kidneys, supporting blood pressure control and hypertension prevention.
Studies support these claims. A research team from Chungnam National University found that corn silk extract reduced vascular inflammation and edema in animal models. The effects were most pronounced when consumed preventively, highlighting its anti-inflammatory and diuretic properties.
The compound maysin in corn silk has been shown to protect liver cells and may help in managing fatty liver disease, giving the tea added benefits for both edema relief and liver health. However, its strong diuretic effect demands caution. Excessive intake may lead to dehydration, electrolyte imbalance, or constipation. For those with kidney conditions like renal insufficiency, it could be harmful. Experts recommend one to two cups daily, paired with adequate water intake.

Pumpkin Tea: Cleansing Blood and Boosting Overall Health
Pumpkin tea, a staple in Korean households, is particularly renowned for reducing postpartum edema. Rich in beta-carotene, a powerful antioxidant, it helps neutralize free radicals and supports vascular health. Its potassium and pectin content aids in expelling sodium and waste, while its diuretic properties help reduce swelling. Notably, mature pumpkins contain higher beta-carotene levels than many other vegetables, such as butternut squash or red bell peppers, contributing to cardiovascular benefits.
Beyond edema relief, pumpkin tea provides vitamins A, C, and B, along with iron and fiber, supporting immune function and blood sugar regulation. A study cited by the U.S. National Cancer Institute reported an association between higher pumpkin intake and a reduced risk of lung cancer, underscoring its broader health benefits, including anti-cancer properties, glucose control, and eye health support.
Caution is warranted, however. Its diuretic effects may cause dizziness or lethargy in those with hypotension, and excessive intake during early pregnancy could lead to discomfort. Since pumpkin tea is often sweetened with honey or rice syrup, people with diabetes should opt for unsweetened versions and consume them in moderation. Experts advise steaming, drying, or boiling clean pumpkins for the safest, most effective preparation, with one cup daily promoting gentle fluid metabolism and overall wellness.

Choosing the Right Tea for Your Body
Both corn silk and pumpkin teas help reduce edema due to their potassium and antioxidant content, which support fluid balance and aid blood pressure control. Yet, their distinct profiles call for tailored choices based on individual health needs.
Corn silk tea, with its strong diuretic and liver-supportive properties, may be suitable for individuals with generalized or facial edema, hypertension, or elevated blood sugar levels. Pumpkin tea is particularly beneficial for postpartum recovery, immune support, and eye health, making it well-suited for individuals in recovery or with weakened immunity.
Both teas require moderation due to their diuretic potency. Individuals with renal disease, hypotension, or diabetes should consult a healthcare provider before consumption. Experts emphasize that while these teas are valuable adjuncts, they work best alongside a balanced diet and healthy lifestyle. Persistent edema, especially with systemic fatigue or weight gain, may signal underlying conditions beyond simple fluid retention, necessitating medical evaluation.
