Use caution if you have hypoglycemia, diabetes or low blood pressure. Consult a physician before use if you are pregnant or nursing, have low potassium levels, using medications for blood pressure, blood-thinning or lowering blood sugar, or if you have gallstones or kidney stones, or obstructed bile duct. Taking corn silk along with other diuretics may result in a sharp decrease in potassium levels.

I suggest consulting a pharmacist or physician before starting any herbal supplement if you are taking a prescription medication or have serious underlying health concerns. 

Energetic/traditional use: Corn is associated with a sweet, neutral, bland energetic orientation. As a food staple throughout history, it also has ties to fertility, abundance and prosperity. Some say it has female energy, but it also has been affiliated with the sun, and the elements of earth and fire. It is commonly used as an offering in harvest ceremonies and Shamanic rituals, due to its associations with the sacredness of nature.
