Coriander

Coriander seed comes from the coriander plant, native to the southwestern Asia and Mediterranean region. The dried fruit (commonly called seeds) is widely used in cuisines across India, Latin America, the Middle East, and Europe. It has a warm, slightly citrusy flavor and appears in curry blends, pickling spices, baked goods, and beverages. The fresh leaves—commonly called cilantro—are a different culinary product with a distinct, fresh, herbal flavor.

Coriander seeds are low in calories and macronutrients when used as a spice in typical serving sizes (1 teaspoon ≈ 2 grams). They contain volatile oils including linalool and alpha-pinene, along with small amounts of fiber and minerals such as manganese and iron. The seed's composition has been studied in traditional medicine for potential digestive effects, though culinary portions are too small to meaningfully alter macronutrient or fiber intake.

Digestive Effects

Traditional use of coriander seed centers on digestive support. Laboratory studies show that coriander seed extract has antimicrobial activity in vitro, and some animal studies suggest effects on gut motility and gas formation. Human clinical evidence is sparse. One small human study found that coriander seed extract reduced bloating symptoms in people with irritable bowel syndrome more than placebo, but this finding has not been replicated at scale and is not established clinical practice. At typical culinary doses, coriander is unlikely to cause digestive harm and may support overall spice diversity in meals.

Tolerance and Considerations

Coriander is well tolerated by most people at culinary doses. Allergic reactions are rare but documented, primarily in individuals with existing pollen allergies to the Apiaceae family (carrots, celery, parsnips, fennel). No established maximum daily intake exists for this spice. People taking anticoagulants or with bleeding disorders should note that some in vitro evidence suggests coriander may have mild antiplatelet effects, though clinical relevance at food doses is unclear; medical consultation is appropriate if concerned. Coriander is not considered a significant source of oxalates or histamines at normal usage levels. FODMAP content at typical culinary serving sizes is considered low, though individuals following a strict low-FODMAP diet should verify current guidance from Monash University.
