Overview

Overview Information

Purple nut sedge is a plant that resembles grass. The tuber is eaten as a source of starch. The tubers and above-ground parts are also used to make medicine.

People use purple nut sedge by mouth for conditions such as diabetes, diarrhea, and indigestion, and apply it to the skin for acne, dandruff, and many other conditions, but there is no good scientific evidence to support these uses.

How does it work?

Purple nut sedge is an antioxidant. It might reduce blood sugar and prevent the growth of certain bacteria, including the type that causes dental cavities. Purple nut sedge might also help break down fat to increase weight loss.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if purple nut sedge is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Bleeding disorders: Purple nut sedge might slow blood clotting. This might increase the risk of bruising or bleeding in people with bleeding disorders.

Slow heart rate (bradycardia): Purple nut sedge might slow down the heartbeat. This could be a problem in people who already have a slow heart rate.

Diabetes: Purple nut sedge might lower blood sugar levels. People with diabetes should monitor their blood glucose levels closely. If you have diabetes, it's best to check with your healthcare provider before starting purple nut sedge.

Gastrointestinal tract blockage: Purple nut sedge might cause "congestion" in the intestines. This might cause problems in people who have a blockage in their intestines.

Stomach ulcers: Purple nut sedge might increase secretions in the stomach and intestines. There is concern that this could worsen ulcers.

Lung conditions: Purple nut sedge might increase fluid secretions in the lung. There is concern that this could worsen lung conditions such as asthma or emphysema.

Seizures: There is concern that purple nut sedge might increase the risk of seizures.

Surgery: Purple nut sedge might lower blood sugar or slow blood clotting. There is some concern that it might interfere with bleeding or blood sugar control during surgery. Stop using purple nut sedge at least 2 weeks before a scheduled surgery.

Urinary tract obstruction: Purple nut sedge might increase secretions in the urinary tract. There is concern that this could worsen urinary obstruction.
