Mojing (Vitex negundo), grows in the valleys of Hejian, Nanyang, and Yuanju, or on the high banks of Pingshou and Duxiang, as well as in fields. Currently, it is also found in Meizhou, Shuzhou, and areas near the capital. This is the variety used to make canes and sticks, commonly known as Huangjing (Yellow Vitex). Its branches and stems are firm and strong, growing in clumps rather than as vines, hence the name "Mu" (Male). The leaves resemble those of Ricinus communis (Castor bean) but are sparser and thinner; the flowers are red and spike-like; the fruits are small and yellow, about the size of sesame seeds; some say it is the small Jing tree. The fruits are harvested in August and September and dried in the shade. There are two varieties, green and red, with the green one being superior.

According to Tao Hongjing's *Dengzhen Yinjue* (Secrets of Ascending to Truth and Hiding): The flowers and leaves of the Jing tree can connect with spirits and reveal ghostly essences. The annotation states: There are three types of Jing trees. The one simply called "Jing wood" refers to the current type used for making canes; its leaves are fragrant, and it has flowers and seeds, but the seeds are not used in medicine. For Daoist arts, Mojing is used, and Mojing seeds are used medicinally; northerners rarely recognize this tree. *Lujia Yinfu* (Six Jia Secret Talisman) says: It is also named Yanglu, also named Kongshu, with white texture and a hollow center. It regenerates when broken and planted. The current Yanglu also regenerates after cutting and planting, but its flowers and fruits are very minute. It is not the variety used by pharmacists. In the third year of Tianjian, the Emperor was preparing to compound Immortal Rice and issued an edict discussing Mojing: Jing trees have white flowers and many seeds; the seeds are coarse and grow sparsely in distinct clusters, usually only three or two stems per cluster, mostly not round, sometimes flat or irregular, resembling bamboo nodes. The leaves are no different from other Jing trees. Bees often gather from Mojing; Mojing juice is cold and sweet. Other Jing trees, when burned, produce smoky fire odor that is bitter. Mojing has a slow constitution and solid juice, preventing smoke and fire from entering it; it is primarily effective for treating Xin Feng (Wind affecting the Heart). At that time, people searched far and wide but could not find it, so they still used Jing leaves. What is currently available is described as follows: Cui Yuanliang's *Jiyan Fang* (Collected Verified Prescriptions) describes a steaming method for waist and leg pain: take Jing leaves without limit, steam until hot and cooked, place them in a jar, ignite fire underneath to warm it, place the patient among the leaves, cover with remaining leaves, and after a short while, sweating should occur within the medicinal environment. Eat slowly, stop when slightly tired, cover with cotton clothes to avoid wind, and administer Congchi Wine (Scallion and Fermented Soybean Wine) and Doujiu (Bean Wine), continuing until recovery. Additionally, take the stems of this Jing tree, cut them, burn both ends over fire, collect the dripping juice in a vessel, and drink it. It treats insomnia (Bu Shui).
