Background
  • Coriander (Coriandrum sativum) is an annual herb in the Apiaceae family. The leaves are also called coriander leaves, Chinese parsley, or cilantro. "Coriander" refers to both the plant itself and the spice produced from coriander seeds.
  • Recipes that call for "fresh coriander" are referring to the leaves (cilantro). Both coriander and cilantro are commonly used in soups, salads, dressings, salsa, and chutney. The leaves are used in curry and guacamole. The roots are used in some Thai recipes. The seeds are used to produce the well-known coriander spice.
  • Ground coriander seed has a distinctive taste, like that of citrus and sage combined. It is quite versatile and can be used in desserts and sweet pastries, Indian curries, meat and seafood dishes, stews, and marinades. It is often used in recipes from Southeast Asia, especially Thailand, as well as China, Mexico, eastern India, South America, and southern Spain.
  • Limited research suggests that coriander may help treat constipation and irritable bowel syndrome, as well as improve vision, digestion, blood sugar, and cholesterol. However, more evidence is needed before conclusions can be made regarding the use of coriander for any medical condition.

You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

Allergies

  • Avoid in people with a known allergy or sensitivity to coriander, its parts, or members of the Apiaceae family. Avoid if allergic or sensitive to mugwort or birch pollen, celery, caraway, fennel, garlic, onion, anise, or dill.

Side Effects and Warnings

  • Drowsiness or sedation may occur. Use caution if driving or operating heavy machinery.
  • Coriander may cause low blood pressure. Caution is advised in people taking drugs, herbs, or supplements that lower blood pressure.
  • Coriander may lower blood sugar levels. Caution is advised in people with diabetes or hypoglycemia, and in those taking drugs, herbs, or supplements that affect blood sugar. Blood glucose levels may need to be monitored by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary.
  • Coriander may cause skin inflammation and hives when touched.
  • Coriander may cause asthma, cough, chest tightness, dry and irritated throat, genital tract infection, inflammation of the eyes, liver problems, lung spasms, narcotic effects, or rhinitis (inflammation of the nose).
  • Use cautiously in people with excessive sun exposure. Coriander may increase sensitivity to light.

Pregnancy and Breastfeeding

  • Use cautiously in pregnant or breastfeeding women. Coriander is likely safe when eaten in amounts generally found in foods in nonallergic women. There is currently a lack of scientific evidence on the use of coriander during pregnancy or breastfeeding.

Interactions

Interactions with Drugs

  • Coriander may lower blood sugar levels. Caution is advised when using medications that may also lower blood sugar. People taking insulin or drugs for diabetes by mouth should be monitored closely by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary.
  • Coriander may cause low blood pressure. Caution is advised in people taking drugs that lower blood pressure.
  • Coriander may interfere with the way the body processes certain drugs using the liver's cytochrome P450 enzyme system. As a result, the levels of these drugs may be increased in the blood and may cause increased effects or potentially serious adverse reactions. People using any medications should check the package insert and speak with a qualified healthcare professional, including a pharmacist, about possible interactions.
  • Coriander may increase the amount of drowsiness caused by some drugs. Examples include benzodiazepines such as lorazepam (Ativan®) or diazepam (Valium®), barbiturates such as phenobarbital, narcotics such as codeine, some antidepressants, and alcohol. Caution is advised while driving or operating machinery.
  • Coriander may also interact with agents for liver damage, agents that may increase light sensitivity, agents that remove heavy metals, antibiotics, anticancer agents, antifungal agents, anti-inflammatory agents, antiparasitic agents, cholesterol-lowering agents, diuretics, fertility agents, gastrointestinal agents, laxatives, and muscle relaxants.

Interactions with Herbs and Dietary Supplements

  • Coriander may lower blood sugar levels. Caution is advised when using herbs or supplements that may also lower blood sugar. Blood glucose levels may require monitoring, and doses may need adjustment.
  • Coriander may cause low blood pressure. Caution is advised in people taking herbs or supplements that lower blood pressure.
  • Coriander may interfere with the way the body processes certain herbs or supplements using the liver's cytochrome P450 enzyme system. As a result, the levels of other herbs or supplements may become too high in the blood. It may also alter the effects that other herbs or supplements possibly have on the cytochrome P450 system.
  • Coriander may increase the amount of drowsiness caused by some herbs or supplements.
  • Coriander may also interact with antibacterial herbs and supplements, anticancer herbs and supplements, antifungal herbs and supplements, anti-inflammatory herbs and supplements, antioxidants, antiparasitic herbs and supplements, cholesterol-lowering herbs and supplements, diuretic herbs and supplements, gastrointestinal herbs and supplements, herbs and supplements for liver damage, herbs and supplements that may increase light sensitivity, herbs and supplements that may promote fertility, herbs and supplements that may remove heavy metals, laxatives, and muscle relaxants.
