Achenes are black, linear, slightly flat, ridged, with sparse tubercle-like protrusions and bristles on the upper part, and 3-4 thorns at the tip with barbed hairs. Flowering period: spring.

[Habitat distribution] Ecological environment: grows beside villages, on roadsides and on barren slopes.

【Properties】 Identification of properties: The stem is obtuse and quadrangular, with a base diameter of up to 6mm. The middle leaves are opposite, and the leaves at the bottom of the stem are smaller and often wither before flowering; the middle leaves are opposite and petiolate, ternate, the leaflets are elliptical or ovate-elliptical, and the leaf margins are coarsely serrated; the terminal leaflets are slightly larger and opposite or alternate. The involucre of the capitula is herbaceous, green, with short soft hairs on the edges; the scapula is membranous, brown on the back, and yellow-brown on the edges; the flowers are yellow-brown or yellow-brown, and there are no ligulate flowers. Sometimes more than 10 long, 4-sided fruits can be seen; the fruit is brown-black, with 3-4 needle-like pappus at the tip and barbs. Slight odor, light taste.

[Pharmacological action] Antimicrobial and antiparasitic effects: 1-phenyl-1,3,5-heptatriene in cecum has obvious broad-spectrum antimicrobial activity against bacteria and yeast. It is effective against all fungi and can inhibit Bacillus subtilis, Streptococcus faecalis, Escherichia coli, Proteus mirabilis, and Candida albicans. Microorganisms such as gypsum spores. Its MICs against Gram-positive bacteria, Gram-negative bacteria, dermatophytes, Rhizoctonia solani and Saccharomyces cerevisiae are 5.20μg/ml, 100-200μg/ml, 10-50μg/ml, 10μg/ml and 10-50μg/ml, respectively. When the concentration is lower than the inhibitory concentration, the spore formation of Microsporum canis can be inhibited. It has been reported that light with wavelengths less than 400 nm is required for antimicrobial activity. The petroleum ether, methanol/water extracts of the dry product of Cecum Officinale and the extracted linolenic acid and linoleic acid also have antimicrobial activity. 1-Phenyl 1,3,5-heptatriene is susceptible to some digenetic trematode cercariae and has a biodegradative effect. 0.3×10(-6) can cause irreversible paralysis of schistosome and echinostoma cercariae within 1-15 minutes. Ultraviolet light has no obvious synergistic effect on killing cercariae.

[Toxicity] When the dried leaves of cecum herb were mixed in the food in a ratio of 1:4 and administered to rats for 1-2 weeks, the [3H]-thymidine incorporation into esophageal endothelial DNA increased by 2.3 times. The ethanol extract and one component of the leaves had a slightly weaker effect. The cecum grass can also be heated and boiled before consumption to increase the dosage. Male rats were given 50 g/kg of dried leaves of cecum herb while induced to carcinogenesis by methyl-n-pentylnitrosamine (MNAN). The rats were killed at 20-45 weeks, 46-52 weeks, and 53-72 weeks. It was found that cecum herb significantly increased the proliferation of esophageal cancer induced by MNAN, and the incidence of carcinogenesis increased significantly with time. However, if not induced by MNAN, cecum herb did not show tumor-inducing effect. The median lethal dose of 1-phenyl-1,3,5-heptatriene for subcutaneous and intraperitoneal injection in mice is 4245 mg/kg and 525 mg/kg.
