Dietary massoia-bark-oil intake via Cryptocarya-massoia-flavoring food-additive cohort + traditional-Indonesian-medicine cohort produces gastrointestinal irritation + sensitizer systemic effects. FDA VCRP + EU Cosmetics Reg 1223/2009 Annex II/III + Council of Europe natural-source restriction frame the consumer-cohort safe-use envelope; finished-product massoia-lactone concentration limits per IFRA 51st Amendment apply.
