About OCIMUM BASILICUM LEAF

Basil leaf — aromatic but complicated. Some chemotypes contain estragole, a genotoxic concern, so chemotype matters.

Detailed Analysis

Ocimum basilicum (sweet basil) leaf is used as extract or essential oil for aromatic, antioxidant, and antimicrobial claims. Composition varies by chemotype: methyl-chavicol (estragole)-rich chemotypes raise genotoxicity concerns flagged by EFSA and the European Medicines Agency, while linalool-rich chemotypes are preferred for cosmetic use but contain linalool and eugenol (EU Annex III fragrance allergens). No positive SCCS opinion specific to basil oil. In well-controlled low-estragole chemotypes at restricted levels the risk profile is manageable, but uncontrolled source material is a genuine concern. Evidence moderate — mechanism and regulatory context are clear.
