Storage method

Packed in galvanized iron drums or glass bottles. Store in a cool and dry place. Keep away from fire and heat sources

Synthesis method

1. Natural sassafras mainly exists in natural plant essential oils such as sassafras oil, camphor oil, South American Brazilian sassafras oil, and North American sassafras oil. It can be isolated from the above essential oils.
