Coriander is used around the world both as a spice and as a traditional medicinal herb.
It contains many nutrients and bioactive compounds that may have positive effects on the body, though most research is still in its early stages.
Antioxidant properties
Coriander contains several antioxidants that help fight free radicals and protect the body’s cells.
These antioxidants can support immune function, reduce inflammation, and have neuroprotective effects.

This can lead to lower blood pressure, but more human studies are needed to confirm this potential benefit.
May reduce anxiety

It may also strengthen the dermal layer and reduce free radicals that contribute to sun damage.

Distinct flavor and aroma

How to use coriander in your diet
Both seeds and leaves can be used as seasoning. Ground coriander enhances flavor, while whole seeds add texture.

Caution with medications
Because coriander may lower blood pressure and blood sugar levels, it should be used carefully by people taking medications for these conditions to avoid excessive lowering effects.
Interaction with sedatives
Some studies indicate that coriander may have a mild sedative effect similar to Valium.
For this reason, combining coriander with sedative medications may increase drowsiness.
More research is needed
While coriander shows promising health benefits, most evidence comes from lab and animal research. More human studies are needed to confirm its potential effects.
