Xu Changqing and Vaccaria seed are both traditional Chinese medicines, but their indications and effects are different and cannot be compared.

Xu Changqing, also known as the turtle fairy, is a perennial erect herb. It is used to treat traumatic injury, toothache and stomachache with excellent effect. In addition, it can also treat intractable skin diseases such as urticaria and eczema.

Liuwang Liuhang, also known as Liuzi and Mailanzi, is a kind of millet. It has a certain effect on reducing swelling of breast, promoting blood circulation and dredging menstruation.
