Iris (Yuanwei): Bitter in taste, neutral in nature. It primarily treats gu poison and evil qi, gui zhu (a highly contagious malignant disease), various toxins, breaks up masses and accumulations (abdominal lumps), promotes urination, and expels three types of parasites. Grows in mountain valleys.
Wu Pu states: Iris can treat gu poison (cited from *Taiping Yulan*).
*Bencao Jing Jizhu* (Collected Commentaries on the Materia Medica) states: Iris is also known as Wuyuan. It grows in Jiuyi Mountain. Harvested in May.
Note: *Guangya* records: Iris is Wuyuan, which is also Shegan (It is suspected that the original text contains an error, likely meaning "Iris is Wuyuan; [Unknown Character] is Shegan," indicating these are two different substances). The *Tang Bencao* commentary states: Iris is completely different from Shegan.
Rhubarb (Dahuang): Bitter in taste, cold in nature. It primarily promotes the discharge of blood stasis, treats amenorrhea due to blood obstruction, and alleviates chills and fever. It breaks up masses and accumulations, clears stagnant fluid retention and leftover food, purges the intestines and stomach, eliminates the old to generate the new, promotes water passage, kills parasites (*Taiping Yulan* adds the character "dao" here), harmonizes the middle jiao, aids digestion, and calms and harmonizes the five zang organs. Grows in mountain valleys.
Wu Pu states: Rhubarb is also known as Hualiang, Huocan, and Furu. Shennong and Leigong considered it bitter and toxic; Bian Que considered it bitter and non-toxic; Li Shi considered it slightly cold and classified it as a "Middle General" herb. Some grow in northern Shu Commandery, others in Longxi. In the second lunar month, flowers emerge; leaves are yellow-red, arranged four by four opposite each other; stems are about three chi high. In the third month, flowers are yellow. In the fifth month, fruits turn black. Roots are harvested in the third month; they contain yellow juice, are sliced, and dried in the shade (*Taiping Yulan*).
*Bencao Jing Jizhu* states: Rhubarb is also known as Hualiang, growing in Hexi and Longxi regions. Roots are harvested in the second and eighth lunar months and dried over fire.
Note: *Guangya* records: Hualiang is Rhubarb.
(Old editions write Tingli; *Taiping Yulan* writes Tingli)
Tingli (Descurainia Seed/Semen Descurainiae): Pungent in taste, cold in nature. It primarily treats masses, accumulations, qi stagnation, and diseases caused by diet, chills, and fever. It breaks up hard accumulations. Also known as Dashì and Dashe. Grows in marshes and fields.
*Bencao Jing Jizhu* states: Tingli is also known as Xiali and Hao. It grows in Cheng. After Lixia (Start of Summer), fruits are harvested and dried in the shade. Processing with wine enhances its efficacy.
Note: *Shuowen Jiezi* records: [Character], is Tingli. *Guangya* records: Gouqi and Dashì are Tingli. *Erya* records: [Character], is Tingli. Guo Pu stated: Its fruits and leaves resemble those of mustard. *Huainanzi · Miucheng Xun* records: Tingli cures Zhang's ailment. *Xijing Zaji* records: Tingli matures during midsummer.
