       The varieties of guanzhong have always been very complicated. In addition to the above-mentioned varieties, there are many kinds of rhizomes of ferns that are used as guanzhong in different regions. For example, the rhizomes of Liaodong Liaodong fern are used in Henan, Shandong, and Hunan; the rhizomes of single-bud fern are used in Gansu, Hunan, Yunnan, and Guizhou; the rhizomes of Lepidopteris are used in Tibet; in Xinjiang. In addition, the Phytophthora chinensis plant in the family Lepidopteridaceae is commonly called Guanzhong, which is consistent with the Guanzhong recorded in "Plant Names and Facts", but the rhizome of this plant is rarely used as medicine at present, only in Sichuan and Yunnan It is used by folks in some counties in , Guizhou, Jiangxi and other provinces, as well as in Nanjing, Jiangsu and other places. See "Dizzy chicken head" article.

       Pharmacological effects:
       There are many varieties of Guanzhong, and most of them have not been identified in pharmacological tests.
       1. Deworming effect
       Trichofern chrysalis, that is, Northeast Guanzhong, the root is called Mianma, which contains 49.17% of Drichomyces semen, and can be used as a substitute for Oumianma to drive away tapeworms. Oumianma can paralyze tapeworms and has a long history of application. According to domestic reports, Guanzhong (unidentified variety) is effective against Ascaris suum in vitro. Drichoptera also repels bovine liver leeches. Its compound decoction has curative effect on bovine fascioliasis and broad fluke.
       2. Antiviral effect
       It was reported in Shanghai that Guanzhong has a strong inhibitory effect on influenza virus (primary influenza A PR strain, Asian A virus) in the chicken embryo test, and is also effective in the mouse (instillation method) test. But the effect is weak. This antiviral effect is related to its tannic acid content (containing 14.5%). Shaanxi also reported that Guanzhong has inhibitory effects on influenza virus A (PR6), Asian A (57-4), B (Lee), C (1233), and D (Sendai). In the tissue culture of primary monolayer cells of human embryonic kidney, it has also been proved that Guanzhong is resistant to adenovirus type 3 of No. 479, polio type II of No. 72, Aike type 9 of No. 44, Coxsackie type A9, Coxsackie type Seven representative virus strains including B6 type, Japanese encephalitis (Jingweiyan 1 strain), and herpes simplex No. 140 have strong antiviral effects. Omega's water decoction also has the effect of anti-herpes simplex virus.
       3. Antibacterial effect
       Reports from Jiangxi, Hunan, and Guangdong show that the local rhubarb has some antibacterial effects, but the effect is not strong. It is used for drinking water disinfection or prevention of epidemic cerebrospinal meningitis in rural areas. It is also said to have some inhibitory effect on skin fungi.
       4. The effect on the uterus
       The decoction and the refined active ingredients have a significant excitatory effect on the isolated and eutopic uteri of rabbits, and the contraction is enhanced and the tension is increased. Trichofern dichotome injection has a significant excitatory effect on the isolated uterus of guinea pigs (0.1-0.7 ml. Each ml is equivalent to 50 mg of crude drug) and rabbits (0.8-1.3 ml), and the movement frequency and tension are increased , the amplitude decreases, and a large dose shows a tonic contraction; but after changing the wash, it can still return to normal. The effect of Ermeiziguanzhong on the uterus is not obvious. According to reports, "Zhenxuejing" composed of Guanzhong and Quanshen has hemostatic, analgesic and anti-inflammatory effects when used externally.
