Also known as Snake's beard, Dwarf lilyturf is a plant native to Southeast Asia. As its name suggests, it is a distant cousin of our famous lily of the valley. In Chinese pharmacopoeia, its root (Mai dong) is known to be a Yin tonic.

Indeed, Mai dong is traditionally used to moisten the Lung and nourish the Yin. Thus, its use is especially recommended after a cold stroke having weakened the Lung.
