Albizia julibrissin, better known as the mimosa tree, is the source of an ancient herb also known as the “calming spirit” or “happiness herb.” The herb usually contains both the bark and the flowers of the mimosa tree, although they are sometimes used separately. In the Chinese Materia Medica, the bark is attributed with “anchoring” the spirit while the flowers “lighten” it.
Ancient medical applications included: calming sedative, effects of grief, depression, melancholy, anxiety, insomnia, amnesia, sore throat and contusion as well as anger due to “constrained emotions.” Although ancient formulas often employed much stronger dosing than contemporary usage, there are no known side effects. However, it is contra-indicated during pregnancy as it may stimulate uterine contractions .
In modern studies, albizia appears to enhance neurotransmitter secretion and regulation. It demonstrates sedative activity, anti-depressant effects and neuroprotective effects. It has also been shown to be anti-inflammatory and to stimulate immune function.
In summary, albizia appears to nourish and stabilize the nervous system through multiple mechanisms. Sounds like a happiness pill with no detriment! Mother Nature in support of human health, again.
