Chive Drug Interactions, Uses, Safety & More

Chive is a small, grass-like herb in the same plant family as onions and garlic. Its thin, hollow green leaves are widely used to add a mild onion flavor to foods like soups, eggs, potatoes, and salads. The plant also produces pretty purple flowers that are edible too.

Chive grows in many parts of the world, including Europe, Asia, and North America, and is easy to grow in home gardens. Most people use chive simply as a culinary herb rather than as a medicine, though it is sometimes promoted for general health because it contains vitamins, minerals, and plant antioxidants.

People most commonly use chive as a flavorful, low-calorie food. Traditionally, herbs in the onion and garlic family have been used to support digestion, freshen breath, and provide nutrients. Some people also believe chive may help the immune system or act against germs.

The scientific evidence for chive as a treatment is very limited. Most research on the Allium family has focused on garlic and onion, not chive specifically. Any antimicrobial or antioxidant effects of chive come mainly from laboratory studies, not well-designed human trials. At this time, there is not enough reliable evidence to say chive treats or prevents any disease. Its clearest benefit is as a nutritious part of a healthy diet.

Like other plants in the onion and garlic family, chive contains sulfur-based compounds that give it its smell and flavor. It also provides vitamin C, vitamin K, folate, and plant pigments called flavonoids and carotenoids, which act as antioxidants.

In laboratory and animal studies, Allium compounds have shown antioxidant and germ-fighting activity. However, these effects are mostly seen in test tubes or animals and may not happen the same way in people eating normal amounts of chive. The proposed mechanisms should be considered preliminary.

Chive is widely eaten and is considered safe for most people in the amounts used in cooking. People who are allergic to onion, garlic, leeks, or other plants in the onion family may also react to chive and should be careful.

Pregnancy and breastfeeding: Eating chive as a normal part of food is likely fine. However, the safety of concentrated chive supplements or extracts has not been studied in pregnant or breastfeeding women, so it is best to avoid those higher-dose products unless your doctor approves.

If you have a bleeding disorder, are scheduled for surgery, or take medicines that affect blood, talk to your pharmacist before using large amounts, since onion-family plants may have mild blood-thinning effects.

In normal food amounts, chive rarely causes problems. Some people may experience mild digestive upset, gas, or heartburn, especially if they eat a lot. Bad breath or body odor can also occur, similar to garlic and onion.

Allergic reactions are possible but uncommon. Stop using chive and seek medical care if you notice a rash, swelling, itching, or trouble breathing.

There is no established medicinal dose for chive. It is normally used in whatever amount tastes good in food. Concentrated chive supplements are not common, and standardized dosing has not been determined by research.

If you choose to use a chive supplement, follow the directions on the product label and check with your pharmacist or doctor first, especially if you take other medicines or have a health condition.
