O
Orégano (Origanum vulgare) é uma planta aromática mediterrânea utilizada
tradicionalmente para reforçar as funções digestivas, respiratórias e
articulares, composta por óleos essenciais
como timol, carvacrol, ácido rosmarínico, além de outras propriedades como: flavonóides,
magnésio, zinco, potássio entre outras.

O óleo essencial
extraído do Orégano é
conhecido em largo espectro, como agente antiviral, antifúngico, antibacteriano
e anti-séptico. Um grande número de estudos in
vitro mostrou que o seu óleo essencial destrói um vasto leque de bactérias
e de fungos.



Um dos
principais ativos por esta ação antibacteriana é o Carvacrol, um monoterpenóide
fenol naturalmente encontrado nos óleos essenciais de segurelha (Satureja hortensis/montana), tomilho (Thymus vulgaris) e no orégano (Origanum vulgare), que contém cerca de
80% de carvacrol em sua composição.

O Carvacrol é um
poderoso agente antimicrobiano, eficaz contra as bactérias Escherichia coli, que quase sempre são as responsáveis pelas
infecções no trato gastrointestinal e urinário, e contras as Bacillus cereus, associadas a doenças de
origem alimentar. Já sua ação anti-inflamatória está relacionada com a enzima
COX-2 (Ciclooxigenase-2), que atua neste processo. 

In vitro, o Carvacrol exercia as suas propriedades antifúngicas contra a
candidíase e sobre uma candidíase oral induzida experimentalmente em ratos
imunodeprimidos, o que sugere que pode constituir um tratamento eficaz da
candidíase oral. Além disso, outras pesquisas mostram a eficácia do Carvacrol
em células tumorais do pâncreas. Conforme um estudo
da Universidade de Long Island,
conduzido pela Dr. Supriya Bavadekar, demonstra que carvacrol estimula a
apoptose em células de câncer de próstata.

Sendo assim
passa a existir um crescente interesse na utilização de óleos essenciais,
devido as suas propriedades, como agente antioxidante, antimicrobiana e anticancerígeno.
Embora a utilização deste material ocorra em maior quantidade nas indústrias de
alimentos, este também vem sendo utilizado em indústrias farmacêuticas em razão
de suas propriedades terapêuticas.
