It primarily treats gu poison (parasitic poisoning), wild poisons, and various toxic pathogens, as well as xinqi guizhu (a condition attributed to spiritual possession or mental disturbance), and eliminates odors such as those of the yakhu bird. Chen states: Its fragrance consists of twelve leaves, making it the essence of all herbs. According to "Wei Lue", it grows in Qin State. It flowers in February and March, resembling Honglan flower; flowers are harvested in April and May for use as a spice. (Currently appended) Twelve leaves form a strand, rubbed and boiled for use as Chang wine (sacrificial aromatic wine), regarded as the essence of all herbs. When combined to brew wine, it is used to invoke deities. Based on this description, it is a herbaceous plant and should not be classified under the woody section.

[Euonymus] Bitter in taste, cold in nature, non-toxic. It treats women's bengzhong xiexue (metrorrhagia and leukorrhea with bleeding), abdominal fullness with sweating, dispels evil pathogens, kills ghost toxins and guzhu, treats zhong'e abdominal pain, expels white worms, reduces skin wind-toxin swelling, and soothes the genital area. Also known as Guijian (Ghost Arrow). It grows in the valleys of Huoshan Mountain. Harvested in August, dried in shade.

Tao Hongjing states: It is found everywhere in mountains and wilderness. Its stems have three barbs, resembling arrow feathers, commonly called Guijian by the populace. However, its usage is rare; when used, the bark and barbs are peeled off. Currently, physicians use Guijian to treat women's blood and qi disorders, with significant efficacy. Ministers Yuxi et al., according to "Yaoxing Lun", state: Guijian, also known as Weimao, has slight toxicity. It can break down old blood stasis, induce abortion, and treat zhong'e lumbar and abdominal pain as well as various evil spirits and demons. Rihua Zi states: Guijianyu (Euonymus branchlet) tastes sweet and astringent. It regulates menstruation, breaks up masses, stops metrorrhagia and leukorrhea, kills abdominal parasites, and treats postpartum blood-stasis abdominal pain.

"Tujing" states: Weimao is Guijian. It originates from the valleys of Huoshan Mountain and may currently be found in Jianghuai prefectures. Stems emerge after March, growing about four to five chi tall. The trunk has three barbs, resembling arrow vanes. Leaves resemble Camellia, green in color. Branches and stems are harvested in August, November, and December, and dried in shade. The wood is also called Gougou (Dog Bone). "Cui Shi Fang" treats malignant guzhu affecting the heart with unbearable pain using Guijianyu Decoction. "Jiyan Fang" treats sudden severe cardiac pain or poisoning by evil qi using Dahuang Decoction which also incorporates Guijian, both being major prescriptions.

Lei Gong states: When processing, do not use Shimao, as its root head resembles Guijian but differs in upper leaves and taste. After harvesting, only the arrowhead part is used. The red hairs on it must be wiped off, and it is slowly stir-fried with butter until the butter is absorbed. For every liang processed, one fen of butter is used, frying until the butter is fully consumed. "Waitai Miyao": Treats lack of lactation. Five liang of Guijian, six sheng of water, boiled down to four sheng. Take eight he per dose, three times daily. Alternatively, administer as an ash-water decoction using a square-inch spoon, three times daily, with great efficacy.

"Yanyi" states: Weimao is found in valleys everywhere, but never seen in flat lands. Leaves are extremely scarce. The stem is yellowish-brown, resembling Cypress bark. Three
