(Natural News) Researchers at Kyung Hee University, Chung-Ang University, and Gachon University in South Korea looked at the efficacy of Aralia continentalis extract on cognitive memory and post-traumatic stress disorder (PTSD). They published their findings in the journal BMC Complementary and Alternative Medicine.
- The researchers aimed to develop a novel treatment for trauma-associated disorders like PTSD, a disease associated with the experience of traumatic stress.
- The traumatic experience results in the development of a prolonged stress response that impairs memory function and increases inflammation in the hippocampus.
- A. continentalis is traditionally used in oriental medicine. It has been reported to possess pharmacological properties, such as anti-inflammatory, anti-cancer, anti-atherosclerotic, and anti-diabetic effects.
- However, its effects on cognitive memory and PTSD are not yet fully understood.
- For the study, the researchers evaluated the effect of A. continentalis on spatial cognitive impairment caused by single prolonged stress in a rat model of PTSD.
- They first induced chronic stress in rats, then treated them with different doses of A. continentalis for 21 consecutive days.
- Treatment with 100 milligrams per kilogram (mg/kg) of A. continentalis inhibited cognitive impairment caused by single prolonged stress.
- It also significantly reduced memory-related reductions in brain-derived neurotrophic factor (BDNF) mRNA and protein levels in the hippocampus.
- Overall, A. continentalis substantially inhibited the cognitive deficits caused by single prolonged stress.
These findings suggested that A. continentalis reversed the behavioral impairments and inflammation triggered by single prolonged stress-derived traumatic stress, indicating its potential as a treatment for PTSD.
