Rating (out of 5): 2

The silk tree (Albizia julibrissin), also known as mimosa, has a long history of use in traditional Chinese medicine, where it is called "He Huan Pi" (bark) or "He Huan Hua" (flower). In traditional practices, it is regarded as a "calm spirit" herb, used to relieve symptoms such as sadness, irritability, stress, and insomnia. These effects are considered to be related to what is now understood as mood support, and by extension, the serotonin system, though traditional sources do not explicitly reference serotonin.

Scientific studies on silk tree’s direct effects on the serotonin system in humans are limited and primarily preclinical. Some in vitro and animal studies suggest that extracts from Albizia julibrissin may have antidepressant-like properties, possibly by modulating neurotransmitters including serotonin, but the exact mechanisms are not well elucidated. Human clinical trials are lacking, and there is insufficient scientific evidence to confirm its effects on the serotonin system specifically.

In summary, the use of silk tree to support the serotonin body system is justified by traditional use, with some preliminary scientific interest but no definitive validation. Its reputation as a mood-calming herb is well-documented in traditional sources, but rigorous clinical evidence is currently lacking.
