CHICAGO (AP) — U.S. authorities in Illinois have seized nearly 90,000 bottles of a beverage containing the herbal ingredient Kratom (KRAT’-um).

A Wednesday statement from the U.S. attorney’s office in Chicago says the bottles are valued at more than $400,000. Prosecutors filed a civil forfeiture complaint that enabled officials to seize them.

Kratom is conclude that Kratom doesn’t pose health risks. It derives from a substance grown in Thailand, Malaysia, Indonesia and Papua New Guinea.

The complaint says Kratom can used by some as a dietary ingredient. The complaint says there isn’t enough information to have stimulant and narcotic effects.

It says the product was manufactured for and held by a company in South Beloit — a community in northern Illinois along the Wisconsin state line.
