Sixteen essential oils were screened in vitro for their fungitoxicity
against the two dermatophytes Trichophyton rubrum and Microsporum gyps
eum. Five oils (from Artemisia nelagrica, Caesulia axillaris, Chenopod
ium ambrosioides, Cymbopogon citratus and Mentha arvensis) showed stro
ng activity and were assessed for their fungitoxicity against eight ot
her dermatophytes as well as against Aspergillus fumigatus and Cladosp
orium trichoides. These five essential oils by formulation of ointment
s were able to cure experimental ringworm in guinea pigs within 7 to 1
2 days. Artemisia oil was found to be the most effective essential oil
