Ticks are obligatory arthropods hematophagous presenting wide distribution and transmission
of various diseases to humans through the association with bacteria, viruses, protozoa among
others. Rhipicephalus sanguineus initially described in 1806 by Latreille, as Ixodes sanguineus,
is a tick considered the most common ectoparasite in dogs. The most common harbourer
diseases are babesiosis caused by Babesia vogeli and erlichiosis caused for agent Ehrlichia canis
which can lead the dog to develop depression, fever and anorexia. The formulations developed
for the control of this type of parasits besides causing resistance to the ticks due to its continuous
use, have toxicological effects that must be taken into consideration, since these substances
(isoxazolines) may accumulate in non-target organisms leading to larger consequences both for
the health of the animal and for the environment in which it lives. As a more effective alternative
to reduce these damage, the use of medicinal plants has been used to eliminate or reduce the
action of these parasites. Plants are recognized as a rich source of biologically active extracts,
essential oils and isolates. Scientific reports on the use of medicinal plants such as Sapindus
saponária, Hyptis suaveolens (L.) Poit e Lippia sidoides with acaricidal action have intensified
in the last decade aiming at the search for active principle for the control of ectoparasites. Given
this, this literature review aims to contribute to the knowledge about the use of medicinal plants
with acaricidal potential already reported in the last 12 years.
