Octacosanol can be considered safe for human use as a therapy, because it is a food-based compound and believed to show no side effects.
Highlights
- Wheat germ oil, rice bran oil, sugar cane and beeswax contain Octacosanol which acts as an antioxidant.
- Octacosanol reduced corticosterone level in blood plasma, which is a stress marker.
- Octacosanol also restored stress-affected sleep back to normal in mice.
The research group led by Mahesh K. Kaushik and Yoshihiro Urade of the International Institute for Integrative Sleep Medicine (WPI-IIIS), University of Tsukuba, found that octacosanol reduces stress and restores stress-affected sleep back to normal.
Octacosanol is abundantly present in various everyday foods such as sugarcane (thin whitish layer on surface), rice bran, wheat germ oil, bee wax. The crude extract is policosanol, where octacosanol is the major constituent. Policosanol and octacosanol have already been used in humans for various other medical conditions.
In the current study, the effect of octacosanol on sleep regulation was tested in mildly stressed mice by oral administration.
- Octacosanol reduced corticosterone level in blood plasma, which is a stress marker.
- Octacosanol-administered mice showed normal sleep, which was previously disturbed due to stress.
- Octacosanol mitigates stress in mice and restores stress-affected sleep to normal in mice.
- The sleep induced by octacosanol was similar to natural sleep and physiological in nature.
Octacosanol can be considered safe for human use as a therapy, because it is a food-based compound and believed to show no side effects. Octacosanol/policosanol supplements are used by humans for functions such as lipid metabolism, cholesterol lowering or to provide strength.
"Future studies include the identification of target brain area of octacosanol, its BBB permeability, and the mechanism via which octacosanol lowers stress," Kaushik says.
