Melissa or Lemon Balm Oil
Tekel et al. (1997) determined that the use of uracil herbicides (Bromacil,Lenacil or Terbacil) during the life cycle of Melissa officinalis L. did not affect the composition of the main oil components such as citronellal,neral, geranial, geranyl acetate,beta-caryophyllene and caryophyllene oxide. Although the authors did not determine the herbicide residues of the oil, they did determine that the highest residues in the plant material were 0.005–0.007 mg/kg.
An oil produced from the air-dried leaves of the ‘Citra’ cultivar of M. officinalis grown in the Slovak Republic was analyzed by Holla et al.(1997).
