Local plant names vary between regions. A seller’s use of taflan or bay does not establish that the correct species for food has been identified.
The scientific name is decisive
Kew distinguishes culinary bay, Laurus nobilis, from poisonous Prunus laurocerasus, also called cherry laurel. Do not use the leaves of these species interchangeably.
Do not judge food safety by appearance
Leaf colour, shine or smell alone is not a reliable food-suitability check. Do not use unidentified material for food, tea or oil preparation. Compare the label’s identity with the supplier’s product documentation.
What purchasing documents should state
Specify Laurus nobilis, leaves, dried product, required grade and intended use. Match the sample and shipment to their batch identity. If a local name differs, clarify identity in writing before treating it as a synonym.
