FAQ for OEM buyers

Q. Is sugi a cross-reactive concern for cedar-pollen-allergic consumers?
Sugi (Cryptomeria japonica) pollen is the dominant cause of springtime hay fever in Japan; the leaf extract is a separately processed material and not equivalent to pollen exposure, but brands should still consider patch-testing and clear allergen messaging. Consider noting genus on allergen-aware product Q&A.
