a phenylpropene and an allyl chain-substituted guaiacol, and
eugenol-related compounds are phenylpropanoids. Because
eugenol is a hepatotoxic substance, excessive ingestion may induce
symptoms such as palpitation, dizziness, vomiting, diarrhea, coma,
spasms, and skin allergies [3e6]. Accidental ingestion of eugenol by
children aged 2 years or younger may cause central nervous system
depression (intoxication) [7], including coma, and metabolic abnormalities
including anion gap acidosis and hypoglycemia, severe
hepatic failure, urinary abnormalities, and coagulation deficits
