Songluo (Pine Mistletoe), its detailed description is appended under the entry for Sangjisheng (Taxillus chinensis).

Ruihe (Prunus mume seed), grows in Hangu Chuan Valley and Baxi, and is now also found in Hedong. The tree is five to seven chi high, with thorns on the stems; the leaves are slender and similar to Gouqizi (Lycium chinense) but sharper and longer; the flowers are white, and the fruits are red-purple, growing attached to branches and stems, resembling Wuweizi (Schisandra chinensis), maturing in June. Fruits are harvested in May and June; the pits and shells are removed, and it is dried in the shade. In ancient and modern prescriptions, it is used only for treating eye diseases. The method recorded by Liu Yuxi in *Chuanxin Fang* is particularly remarkable. He stated: For eyes suffering from wind-induced tearing and itching, or developing nebula (corneal opacity), or redness, this can be used to treat all such conditions. Take Xuanzhou Huanglian (Coptidis Rhizoma), crush and sieve into powder; take Ruihe Ren (Prunus mume seed kernel), remove the skin, and grind into a paste. Because this substance is slightly moist, it cannot be mixed directly as powder with Huanglian; instead, mix the Ruihe paste and Huanglian powder in equal proportions. Take three dry jujubes without defects, cut off a small portion of the top and set aside, remove the pit, and fill the cavity completely with the two substances. Replace the cut-off jujube top and secure it. Wrap it in a small amount of cotton, preferably thin cotton. Place half a large teacup measure of water in a silver vessel, and decoct using moderate or strong heat until the volume reduces to approximately that of one chicken egg. Filter through cotton, wait for it to cool, and instill into the eyes; the effect will be infallible. Dozens of trials have been effective. Current physicians also use this method frequently with good results, so it is appended here.

Wujiapi (Acanthopanacis Cortex), grows in Hanzhong and Yuanju, and is now available in various prefectures of Jianghuai and Hunan. Sprouts emerge in spring; stems and leaves are green, growing in clumps, with reddish stems, resembling vines, three to five chi high, covered with black thorns. Leaves clustered in fives are considered best; those with four or three leaves are most common but of inferior quality; each leaf has a thorn beneath it. White flowers bloom in March and April; small green fruits form, turning gradually black by June. The root resembles Jinggen (Vitex negundo root); the bark is yellow-black, the flesh white, and the wood hard. Stems are harvested in May and July, roots in October, and dried in the shade for use. People in Qizhou call it Muguzhi. Another view states that there are several types currently used as Wujiapi: Those from the capital region and northern areas are large pieces resembling Qinpi (Fraxini Cortex) or Huangbai (Phellodendri Cortex), flat and board-like, white in color, with no distinct odor, quite effective for treating wind-pain, but others are not used medicinally; in Wuzhong, the bark of wild Chun trees (Toona sinensis) is peeled and used as Wujiapi, which is flexible and tasteless, a significant error; what is produced in the Jianghuai region today is the true variety, resembling Digupi (Lycii Cortex), light, crisp, and aromatic. Its shoots and stems have thorns like Rosa roxburghii, some growing over a zhang long; leaves are palmately compound with five leaflets like peach blossoms, with an aroma similar to olive; fruits form in spring, bean-sized and flat, green in spring, turning purple-black after frost. These are also abundant in Wuzhong, commonly known as Zhuifengshi (Wind-Chasing Envoy) or Citong (Thorn-Penetrator). When peeled and soaked in wine to treat wind disorders, people do not realize it is Wujiapi. In Jianghuai and Wuzhong, it is often used as hedging, resembling Rosa roxburghii or Rubus corchorifolius, exactly as described above. However, people in the north rarely know to use this type. It can also be used to brew wine; drinking it treats wind-bi (wind-damp obstruction) causing spasms and stiffness in the four limbs.
