Lovage is a plant. The root and underground stem (rhizome) are used to make medicine.

Lovage is used for kidney damage in people with diabetes (diabetic nephropathy), indigestion, kidney stones, cough, and many other conditions, but there is no good scientific evidence to support these uses.

In foods and beverages, lovage is used for flavoring.

In manufacturing, lovage is used as a fragrance in soaps and cosmetics.
When taken by mouth: Lovage is LIKELY SAFE for most people when used in amounts commonly found in foods. It is POSSIBLY SAFE for most people when taken as a medicine in appropriate amounts, short-term. Taking lovage may increase sensitivity to the sun. This might put you at greater risk for rashes from the sun, sunburns, and skin cancer. If you are taking lovage, wear sunblock and protective clothing outside, especially if you are light-skinned.

Special Precautions & Warnings:

Pregnancy: Lovage is LIKELY UNSAFE during pregnancy. There are some reports that it might cause the uterus to contract or start a menstrual period. This could cause a miscarriage.

Breast-feeding: There isn't enough reliable information to know if lovage is safe to use when breast-feeding. Stay on the safe side and avoid use.

High blood pressure: There is a concern that lovage might increase the amount of sodium in the body, and that might increase blood pressure.

Kidney problems: Do not use lovage if you have poor kidney function.

Lovage seems to work like "water pills" by causing the body to lose water. Taking lovage along with other "water pills" might cause the body to lose too much water. Losing too much water can cause you to be dizzy and your blood pressure to go too low.

Some "water pills" include chlorothiazide (Diuril), chlorthalidone (Thalitone), furosemide (Lasix), hydrochlorothiazide (HCTZ, Hydrodiuril, Microzide), and others.
