Frequently asked questions

Can I give star anise tea to my baby?

No. Seizures, irritability and vomiting have been reported in infants given star anise tea, and toxic Japanese star anise was found in products. Do not give it for colic; ask your doctor.

Is star anise good for cough?

Germany's Commission E accepted its traditional use for cough and bronchitis. No clinical trials confirm this.

Is star anise the same as anise?

No. Anise (Pimpinella anisum) is a seed from the carrot family, while star anise (Illicium verum) is the fruit of a tree. They taste similar because both contain anethole.

How can you tell Japanese star anise apart?

It is hard to tell by eye, as the two species look almost the same. Buy from a reliable source with Illicium verum on the label.

Does star anise help with gas?

It is used for gas and digestive complaints, but its benefit has not been well studied.
