A composition of a fatty acids, essential oils, plant extracts, phenols, and terpenoids and used for treating Lyme disease is disclosed. Compositions as a mix of ingredients was tested in various combinations and concentration against active (spirochetes), as well as persistent/latent forms, (knob-shaped/rounded-forms) and biofilm of the bacteria, i.e., Borrelia burgdorferi and Borrelia garinii. The results document pleiotropic effects of the tested combinations against all tested forms of Borrelia sp. and show their better efficacy than doxycycline—the current antibiotic treatment against Lyme disease.
