PROVATA L’AZIONE FARMACOLOGICA SUL SONNO DELL’OLIO ESSENZIALE DI VETIVER

Gli oli essenziali sono stati largamente sfruttati per modulare le funzioni mentali anche se la maggior parte dei dati sono stati ottenuti da metodi soggettivi di valutazione.

Gli effetti diretti degli oli essenziali sulla funzione cerebrale sono stati tuttavia in gran parte confermati con prove scientifiche.

Alcuni ricercatori indiani (Cheaha D, Issuriya A, Manor R, Kwangjai J Rujiralai Kumarnsit E) hanno voluto verificare gli effetti farmacologici dell’ olio essenziale di vetiver.

Gli esperimenti sono stati condotti tra novembre 2013 e febbraio 2014 su modelli in vivo (ratti) e sono stati eseguiti impiantando degli elettrodi sul cranio degli animali per effettuare un elettroencefalogramma.

Al termine della ricerca è stato confermato che l‘inalazione di olio essenziale di vetiver ha interferito sulla quantità e qualità del sonno.

E’ stato in particolare osservato come l‘inalazione dell’olio essenziale di vetiver diminuiva l’attività alfa e beta1 sia nella corteccia frontale che in quella parietale e aumentava l’attività gamma nella corteccia frontale.

I ricercatori hanno osservato come i cambiamenti in queste aree cerebrali variavano non appena gli animali iniziavano ad inalare l’olio essenziale. Questi dati suggeriscono proprietà rinfrescanti del Vetiver  sull’attività cerebrale elettrica e la vigilanza.
