[Ai Xiang (Mugwort Fragrance)]
Taste: Sweet. Nature: Warm. Toxicity: Non-toxic. Removes foul odors, kills parasites, and primarily treats cold-induced diarrhea and dysentery in the abdomen. *Guang Zhi* states: It originates from Western Regions countries, resembling fine mugwort. There is also a green moss on pine bark, also named Ai Na. It can be blended with other fragrances; when burned, it gathers its smoke into a cohesive, non-dispersing blue-white plume, which differs from this substance. (This entry was appended later.)
Minister Yuxi et al., according to ancient pharmaceutical poetry, state: "Where do traveling Hu people come from? What do they bring from various states? Qushu, Wumu Xiang, Rosemary, Mugwort, and Duliang." These refer to such substances.
Chen Cangqi states: Primarily treats tinea and repels insects. *Hai Yao Ben Cao* records: According to *Guang Zhi*, it grows in Piao State, is warm and neutral in nature. It treats Shanghan (Cold Damage), five types of diarrhea, Zhu Qi (accumulated pathogenic qi) in the heart and abdomen, expels Taenia solium (pinworms/roundworms), and stops borborygmus. Burning it repels epidemics; combined with treatments for insect stings, or used for bathing to treat Hongxiangjiao (tinea pedis/granuloma inguinale), it is very effective.
[Gansong Xiang (Nardostachys Root)]
Taste: Sweet. Nature: Warm. Toxicity: Non-toxic. Primarily treats foul odors, sudden epigastric and abdominal pain with fullness, and is used to blend with various fragrances. It grows in clusters with fine leaves. *Guang Zhi* states: Gansong Xiang originates from Guzang. (This entry was appended later.)
Minister Yuxi et al., citing Ri Hua Zi, state: It treats epigastric and abdominal distension and directs Qi downward. Made into a bath decoction, it makes the body fragrant.
*Tujing* states: Gansong Xiang originates from Guzang; currently found in Qian, Shu prefectures, and Liao Zhou. It grows in clusters in mountains and wilds, with leaves as fine as thatch grass and extremely dense roots. Harvested in August, boiled for bathing to impart fragrance to the body.
Chen Cangqi states: Grows in clusters with fine leaves, originating from Liangzhou. *Hai Yao Ben Cao* records: According to *Guang Zhi*, it originates from Shengyuan State, with slender stems growing by trailing vines. Chen's notes state: It primarily treats black skin lesions, wind-related dental caries, and "wild chicken hemorrhoids." It works well when combined with Bai Zhi (Angelicae Dahuricae Radix) and Fu Zi (Aconiti Lateralis Radix Praeparata). It is excellent for blending fragrances and fumigating clothes.
[Yuan Yi (Wall Moss)]
Taste: Sour. Toxicity: Non-toxic. Primarily treats jaundice with vexation, coughing with rebellious Qi and blood, acute heat in the stomach and intestines, and internal blockage from metal wounds. Long-term consumption tonifies the Middle Jiao and benefits Qi, enhancing complexion. Also known as Xi Xie, Wu Jiu, Yuan Lei, Tian Jiu, and Shu Jiu. Grows in the shade of old walls or on roofs. Harvested on the third day of the third lunar month, dried in the shade.
Tao Hongjing states: Not widely used in prescriptions; rarely seen in common practice. It is mentioned in *Li Sao*. Some say it is Tian Suan. *Tang Ben Cao Zhu* states: This is the green moss growing on the north side of old walls. Those growing on stones are named Xi Xie, also known as Wu Jiu. Since there are few walls in Jiangnan, Tao stated it is rarely seen. *Ben Jing* records it; those on roofs are named Wu You. Listed in the Lower Grade, their shapes are similar, and therapeutic effects are roughly the same. *Bie Lu* states: It primarily treats acute facial paralysis with jaw lock (kou jin), metal wounds, and is effective when taken after wine infusion. Minister Yuxi et al., citing Ri Hua Zi, state: Yuan Yi is cold in nature. He also states Di Yi (ground moss) is cold and slightly toxic. It treats sudden heart pain and evil Qi invasion. Formed into pills using human dirt and grease, seven pills per dose. This refers to moss rising from damp ground exposed to sun, mixed with oil to apply to equine ulcerative sores, which is effective.
*Tujing* states: See textual content under the Seaweed (Hai Zao) entry.
