Coriander is a plant. Both the leaves and fruit (seeds) of coriander are used as food and medicine. However, the term "coriander" is typically used to refer to the fruit. Coriander leaves are usually referred to as cilantro. In the following sections, the term "coriander" will be used to describe the fruit.
Coriander is taken by mouth for stomach and intestinal problems including upset stomach, nausea, diarrhea, intestinal gas, constipation, and irritable bowel syndrome (IBS). It is also taken by mouth for convulsions, insomnia, anxiety, and to treat infections caused by bacteria and fungus. Coriander is also taken by mouth for diabetes, worms, and joint pain and swelling.
Some breast-feeding women use coriander to increase milk flow.
In foods, coriander is used as a culinary spice and to prevent food poisoning.
In manufacturing, coriander is used as a flavoring agent in medicines and tobacco and as a fragrance in cosmetics and soaps.
How does it work?
Coriander might stimulate the gut and increase the production of stomach acid. This might help people with conditions such as indigestion, constipation, or intestinal gas. Coriander my also reduce muscle spasms in the gut. This might help treat stomach conditions such as diarrhea. Coriander may also lower blood sugar by stimulating insulin production. Coriander may also lower blood pressure by causing blood vessels to dilate and working like a "water pill" (diuretic).
Insufficient Evidence to Rate Effectiveness for...
- Constipation. Early research suggests that drinking a specific tea containing fennel, senna, licorice, orange peel, cassia cinnamon, coriander, and ginger (Smooth Move by Traditional Medicinals) for one month can reduce constipation in older people.
- Irritable bowel syndrome (IBS). Early research shows that taking 30 drops of a product containing lemon balm, spearmint, and coriander (Carmint, Pour Sina) three times per day after meals for 8 weeks reduces stomach pain and discomfort in people with IBS when used along with diarrhea medicine (loperamide) or psyllium.
- Bacterial or fungal infections.
- Intestinal gas (flatulence).
- Joint pain and swelling.
- Nausea and diarrhea.
- Stomach upset.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Coriander is LIKELY SAFE in food amounts and POSSIBLY SAFE for most people when taken by mouth in appropriate medicinal amounts.
When taken by mouth or inhaled, coriander can cause allergic reactions. Symptoms of such reactions can include asthma, nasal swelling, hives, or swelling inside the mouth. These reactions appear to be most common in people who work with spices in the food industry.
When coriander comes in contact with the skin, it can cause skin irritation and inflammation.
Allergies. People who are allergic to mugwort, aniseed, caraway, fennel, dill, or similar plants might have allergic reactions to coriander.
Diabetes. Coriander might lower blood sugar levels. If you have diabetes and take coriander, monitor your blood sugar levels closely.
Low blood pressure: Coriander might decrease blood pressure. This could cause blood pressure to go to low in people with low blood pressure. Use cautiously if you have low blood pressure or take medications to lower your blood pressure.
Surgery: Coriander might lower blood sugar. There is some concern that it might interfere with blood sugar control during surgery. Stop using coriander at least 2 weeks before a scheduled surgery.
Medications for diabetes (Antidiabetes drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Coriander might lower blood sugar. Diabetes medications are also used to lower blood sugar. Taking coriander in medicinal amounts along with diabetes medications might cause your blood sugar to go too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.
Some medications used for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.
Medications for high blood pressure (Antihypertensive drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Coriander might decrease blood pressure. Taking coriander in medicinal amounts along with medications for high blood pressure might cause your blood pressure to go too low.
Some medications for high blood pressure include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), Amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.
Sedative medications (CNS depressants)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Coriander might cause sleepiness and drowsiness. Medications that cause sleepiness are called sedatives. Using coriander in medicinal amounts along with sedative medications might cause too much sleepiness.
The appropriate dose of coriander depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for coriander. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
