Abstract
|
|
|
|
The effects of inhaling three essential oils (lavender [Lavendular angustifolia], silver fir [Abies alba], and grapefruit [Citrus paradise]) against restraint stress were investigated in mice. Serum cortisol levels were significantly increased in the 1h-restraint group. Also, silver fir and grapefruit oils prevented the elevation of cortisol levels under experimental conditions. Inhalation of 10% lavender oil for 30 min before inducing stress significantly inhibited restraint-induced hypothermia. We also investigated the effects of restraint stress on triglycerides, total cholesterol, and high-density lipoprotein cholesterol. It was found that the concentration of triglycerides in the serum samples increased after restraint stress. Silver fir essential oil inhibited elevation of triglyceride levels. Taken all together, the correlation of herb essential oil inhalation against restraint stress in animals can partly be explained.
