Chaenomeles speciosa Identity & Plant Part
The botanical entity is Chaenomeles speciosa (Sweet) Nakai, the flowering quince, a thorny Rosaceae shrub with bright red-orange spring blossoms. The part used is the fruit. Leaves, flowers and seeds are not part of this ingredient. In Chinese herbal trade the fruit is known as mu gua, and that name is also applied to related quince fruits.
That shared name is the identity risk. Chaenomeles sinensis is a sister species with larger, smoother fruit, and common quince, Cydonia oblonga, is a different genus. Chaenomeles speciosa fruit carries organic acids, procyanidins, triterpenic acids and pectin, named only as families.
