Cuscuta chinensis Identity & Plant Part
The botanical entity is Cuscuta chinensis Lam., Chinese dodder or tu si zi, a thread-like parasitic vine of the Convolvulaceae that twines over host plants and has no true leaves of its own. The part used is the seed, small, round and brown. Stems, flowers and the vine itself are not part of this ingredient.
Dodder is a genus of many look-alike species, and Cuscuta australis and Cuscuta japonica seed is sometimes traded under the same name. The botanical name is therefore the safe identifier. Cuscuta chinensis seed carries flavonoids including astragalin and hyperoside, along with chlorogenic acid, lignans and polysaccharides, named only as constituent families.
Cuscuta chinensis seed is harvested after the parasitic vine has set fruit, and cleaned seed is the starting material for the extract.
