Inhalation of phlai-containing essential oil enhances cognition: a comparison with olive oil in healthy adults.

ABSTRACT:

Background/objectives

Phlai (Zingiber montanum and Zingiber tenuiscapus), traditionally valued for its anti-inflammatory properties, has potential applications as a functional ingredient in sustainable food systems. However, its effects on cognitive function are not well understood. This study investigates the acute cognitive effects of inhaling Phlai-containing essential oil in healthy adults, aiming to explore its potential as a basis for developing plant-based cognitive enhancers within the context of nutritional sustainability.

Methods

A double-blind, randomized, controlled trial was conducted with 40 healthy male volunteers. Participants were assigned to either an olive oil group (n = 20) or an essential oil blend (ESOB) group (n = 20), with Phlai as the p
