Safety

Carcinogenic concern

Carcinogenic concern based on 0.3 percent methyleugenol content.

Methyleugenol is a rodent carcinogen at high doses.

Per studies, oral β-myrcene caused reproductive toxicity in pregnant rats at 500 mg/kg. African bluegrass does not require specific limits on this front.

No specific skin irritation data. From composition, skin reaction risk is low.
