Cornsilk is considered very safe, gentle, and well-tolerated. It has a long history of traditional use.

Cautions

Medication interactions (possible):

Cornsilk contains vitamin K; use caution with anticoagulant/antiplatelet medications.

Its diuretic effect may increase clearance of some drugs or interact with pharmaceutical diuretics.

Hypokalemia risk:

Strong or prolonged diuretic use could theoretically lower potassium, although cornsilk is naturally potassium-rich, making this uncommon. 

Diabetes / blood sugar:

Some evidence suggests cornsilk may modestly affect blood glucose; individuals with diabetes should monitor for changes.
