Reduced ability to control emotions may be diagnosed as pseudobulbar affect, pathological laughter and crying, emotional lability, emotionalism, emotional dysregulation, or, more recently, involuntary emotional expression disorder (IEED) is a characteristic of several conditions. including Chronic Fatigue Syndrome, Alzheimer’s disease, and brain injury. Brain injury includes many types of neurological disease, including stroke, tumors, and neurodegenerative gray and white matter disorders. It is also associated with complications of disorders of the adrenal glands which likely includes andrenal fatigue .There are no US Food and Drug Administration-approved treatments for this.
The depression that comes from CFS may be associated with less severe injury or injury in other locations. Studies have found that it appears to be associated with certain areas of the brain being impacted  other studies believe it is a disruption of the pathways involving serotonin and glutamate.
Checking on PubMed for “Emotional Lability herbs” found nothing. I have experienced this and found that the following herbs dampen the emotional swings.
It was interesting to note that a Chinese Medical Guide gives only one mixture for treating emotion lability, “Strenght Heart” containing
- Chinese salvia root (dan shen)
- jujube seed
- schisandra fruit
- lophatherum leaf & stem
- ophiopogon tuber
- polygala root
- Chinese licorice root
- lotus seed
- lotus plumule
- Asian ginseng
Jujbe seed alone, is reference on other chinese medicine pages for this condition. I was unable to find any Ayudevia pages citing which herbs to treat it with.
