In coriander, flavor plus health benefits

Gin, curries, chutneys, Mexican dishes and Mediterranean dips often have an ingredient in common: Coriandrum sativum. Known as coriander, Chinese parsley or cilantro (when referring to the leaves alone), the plant is used in cuisines worldwide. This ancient herb (Egyptian writings reveal it was used more than 3,000 years ago) is also reputed to rev up appetites and calm upset stomachs.

Uses: In folk medicine traditions, coriander has been used to treat vomiting, heartburn, sore throat, coughing, chest pain, diarrhea, hemorrhoids, measles and anthrax, and to increase longevity. Supplements containing the seed are touted as expectorants.

Dose: Three grams a day, taken in three separate doses. Coriander is sold in capsule form. The leaves can also be dried and crushed to make an herbal tea (use two teaspoons of dried herb per cup of water).

Precautions: Some people may be allergic to the spice.

Research: In several lab studies, oils from coriander seeds have destroyed fungi and bacteria, including salmonella. Animal studies suggest the herb spurs digestive enzymes into action, which may explain its reputation as an appetite enhancer. Recent experiments suggest the herb can also lower levels of harmful cholesterol in the blood.

Dietary supplement makers are not required by the U.S. government to demonstrate that their products are safe or effective. Ask your healthcare provider for advice on selecting a brand.
