The bark of this exotic tree is especially famous among the Chinese for use when one is experiencing emotional problems such as a broken heart and the experience of great loss. It is also used to help overcome excessive worry, fright, paranoia and insomnia. It is considered to be a Spirit tonic which nourishes the heart and strengthens the body.

Both the bark and the flower are considered to have these qualities, but the flower is more rare and is believed to be one of the ultimate Shen tonics.
