[Litsea Fruit]
Taste: bitter. Nature: cold. Toxicity: slightly toxic. Indications: Treats warm diseases (exogenous febrile diseases caused by warm pathogens), severe high fever, irritability, and mania caused by Shanghan (cold damage); kills intestinal parasites; treats scabies and skin ulcers; promotes urination through the water passages. Root: Nature: slightly cold. Indications: Treats ascariasis; promotes bowel movement. Habitat: Grows in the valleys of Mount Jing.
[Willow Flower]
Grows everywhere. Folk custom dictates that on the fifth day of the fifth lunar month, people gather flowers and leaves to wear as amulets, claiming they ward off evil. Grinding the root with vinegar and applying it to scabies is very effective. Boiling the juice to make porridge for consumption. [Note]: This plant has two types: male and female. The male type has a red root, produces no fruit, is toxic, and ingestion often causes unceasing vomiting, sometimes leading to death. The female type has a white root, bears fruit, is slightly toxic, and the female should be selected for use.
Taste: bitter. Nature: cold. Toxicity: non-toxic. Indications: Treats Fengshui (edema accompanied by wind-pathogen symptoms), jaundice, facial heat and darkening, crusted scabies, malignant sores, and metal weapon wounds. Also known as Liu Xu (willow catkins). Leaves treat equine scabies and crusted sores. Taking the decoction to wash horses with scabies leads to immediate recovery. Also treats intra-abdominal blood stasis, relieves pain, primarily treats suppurating carbuncles, and expels pus and blood. Juice from seeds treats thirst. Habitat: Grows in Langya.
Willow refers to the current Shuiyang (water poplar/willow). Flowers mature and scatter with the wind, resembling flying snow. When Chen Yuanzheng used it as a metaphor, he likely referred to its state before unfurling; seeds also fly with the flowers, corresponding to the method of soaking in water to extract juice. Willow flowers are also suitable for topical application on moxibustion sores; bark and leaves treat lacquer dermatitis. [Note]: Willow and Shuiyang are completely different. Shuiyang leaves are round, broad, and reddish, with short, stiff branches; willow leaves are narrow and long, green, with long, soft branches. This discussion concerns willow, not Shuiyang. Although Shuiyang has therapeutic effects, it is not recorded in this Materia Medica. Branches, insect frass within the wood, and branch bark: Taste: bitter. Nature: cold. Toxicity: non-toxic. Indications: Treats phlegm-heat strangury; can be used as an emetic decoction; boiled for washing to treat wind-induced swelling and itching. Decocted in wine and held in the mouth treats toothache. Insect frass from the wood can be used in bath water to treat wind-induced pruritus and urticaria, with significant efficacy. This is the common willow tree found among humans. Tao Hongjing stated that Shuiyang is not... [text fragment regarding moxibustion sores].
[Tung Leaf]
Taste: bitter. Nature: cold. Toxicity: non-toxic. Indications: Treats erosive sores affecting the genitalia. Bark treats five types of hemorrhoids and kills three types of parasites. Treats Ben Tun Qi disease (a condition characterized by gas rising from the lower abdomen to the chest/throat). Flowers applied to pig sores cause pigs to gain three times their weight when fed. Habitat: Grows in the valleys of Tongbai Mountain.
There are four types of Tung trees: Qingtong (Green Tung), with green stem bark and leaves resembling Wutong but without fruits. Wutong (Chinese Parasol Tree), with white coloration, leaves resembling Qingtong and bearing fruits, which are plump and edible. Baitong (White Tung) is indistinguishable from Gangtong except for having flowers and seeds; flowers open in March, yellow-purple in color, as mentioned in the *Book of Rites*: "The tung tree blooms first." Gangtong bears no fruit and is used for making qin and se musical instruments. Since this text mentions flowers, it must refer to Baitong. Baitong can also be used to make musical instruments and is also known as Yitong; households often plant it. [Note]: Ancient Materia Medica records that feeding tung flowers to pigs causes them to triple in weight. The claim here that it is applied to sores is likely erroneous. Who would intentionally wound a pig and then apply tung flowers?
