Hehuan (Albizia julibrissin)
(Same as Jiaozhi Tree)
Sweet in taste, neutral in nature. Non-toxic. Mostly produced in Yongzhou and Luozhou regions, (both belonging to Henan Province.) Often planted in courtyards and on steps. Leaves resemble those of the locust tree, very dense and luxuriant; wood resembles paulownia but branches are soft. Its branches interlock with each other, naturally separating when the wind blows, hence named Hehuan (Happy Union), commonly called Jiaozhi Tree (Interlocking Branch Tree). Bark and leaves can be harvested at any time of the year. Benefits the mind and will, nourishes Yin, calms the five Zang organs, and brightens the eyes. Makes people's affairs go smoothly, bringing frequent peace, joy, and freedom from worry. Bark decocted into a thick paste can dissipate swelling and carbuncles, and reconnect broken bones and tendons; leaves crushed to extract concentrated juice can wash clothes to remove black stains and mildew.

Jiegu Mu (Sambucus williamsii)
Sweet and bitter in taste, neutral in nature. Slightly toxic. (The *Shennong Bencao Jing* states: non-toxic. This is an error.) Trees grow about one or two zhang high, light and hollow-hearted; branches inserted into soil take root easily, widely planted near the capital. Flowers and leaves resemble *Eupatorium fortunei* (Luying) and water celery, hence also named Mushu Diao. Specifically used to reconnect tendons and bones, capable of restoring life from death. For fractures and injuries, frequently soaked in wine and swallowed; for wind-induced itching, suitable for medicinal baths. Regardless of whether boiled three times or more, the efficacy remains the same. Also expels various postpartum disorders, frequently used in gynecological prescriptions. Leaves treat malaria; fresh leaves crushed for juice ingestion, (seven leaves for adults, three for children,) induces vomiting of cold and heat pathogens, leading to complete relief. Root bark collected and decocted orally can eliminate phlegm-malaria, abdominal distension, and dysentery. Stop medication upon seeing effects; do not finish the entire course. Another variety called Zheshang Mu is mostly produced in mountainous areas of Zizhou (Sichuan Province). It is a vine winding around large trees to grow long, with leaves round and thick like fennel grass. Harvest stems in August and September, dry them in the sun. Has special merit in treating fracture injuries to bones and tendons, and immediate effect in dispersing postpartum blood stasis and dysentery. Decocted with wine and water for drinking, same as previous methods.

Mujin (Hibiscus mutabilis)
Bitter in taste, neutral in nature. Non-toxic. Stems are not tall, found everywhere. Flowers pale red, opening in morning and closing at dusk; leaves pale green, withering in autumn and regenerating in spring. Planted along roadsides, they can serve as hedges; for medicinal use, flowers and branches are used separately. Branches treat heat and thirst after dysentery, induce sleep; juice extracted dyes silk, making it soft, smooth, and easy to dye. Flowers treat diarrhea, dysentery, and intestinal wind, astringe intestines, stop bleeding; decocted as tea gradually dispels wind-induced itching. Both parts should be stir-fried before use.
