Lotus is a plant that grows in lakes and rivers. The flowers, seeds, leaves, and parts of the underground stem (rhizome) are used to make medicine.

People use lotus for bleeding, cough, fever, liver and stomach problems, and other conditions, but there is no scientific evidence to support these uses.

In Asia, various parts of the lotus plant are commonly used for cooking, baking, and adding flavor to beverages.
When taken by mouth: Lotus is LIKELY SAFE when eaten as food. However, there is not enough known about lotus to know if it is safe when used as a medicine. It can cause allergic reactions such as skin itching in some people.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking lotus as medicine if you are pregnant or breast-feeding. Stay on the safe side and avoid use.

Diabetes: Lotus might lower blood sugar levels in some people. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully if you have diabetes and use lotus as a medicine.

Surgery: Lotus might lower blood sugar levels. There is concern that taking lotus as a medicine might interfere with blood sugar control during and after surgical procedures. Stop using lotus at least 2 weeks before a scheduled surgery.
