Description

Chmielewski and co-authors check whether herbal supplements on Polish shelves were secretly irradiated, in this 2026 pilot study. Irradiation kills microbes and extends shelf life, but European rules demand a label whenever it is used. The team focused on products containing valerian root.

A lab test that reads stored light in minerals was run on fifteen samples from eleven products. Seven samples showed the glow pattern typical of past irradiation. Every positive sample contained valerian root, including repeat batches of two brands. None of the positives declared irradiation on the label. The authors flag a gap between market practice and labeling law. They call for routine checks on supplement supply chains.
