The resin supplier, Resinate, addresses food safety in their FAQs indicating their resins are safe for incidental contact with food. Although ‘herb’ is not necessarily considered a food item, I still highly recommend placing a layer of waxed paper, parchment paper, or similar between the jar and its loose contents, or store in its original packaging inside the jar. For expected prolonged contact with the tray, the same is recommended. It will help to ensure your safety, and prolong the life of the item as well..
