Kiwi pear root is a common Chinese medicine in clinical practice. For people with poor physical constitution, eating kiwi pear root can help us maintain better health. Today I will introduce kiwi pear root to you.

【Other name】 Fujin pear root

[Source] Medicinal material source: Actinidia arguta (Sieb. et Zucc.) Plarich. exMiq． Root.

[Original form] Actinidia arguta is a large vine that can grow over 30 meters in length. Young branches are sometimes covered with grayish white sparse soft hairs, while old branches are smooth; pith is brown and flaky. Simple leaves are alternate; petioles and veins are often black when dry; leaf blades are membranous or papery, ovate, elliptical-ovate or oblong, 16-13cm long, 5-9cm wide, with pointed or short-tailed tips, rounded or cordate bases, rarely nearly cuneate, with sharp serrations on the edges, light brown or grayish white soft hairs in the vein axils on the underside, and otherwise glabrous. Cymes are axillary, with 3-6 flowers; flowers are unisexual, dioecious or unisexual and bisexual flowers coexist; flowers are white, 1.2-2cm in diameter; perianth is 5-membered; sepals are hairy only on the edges; stamens are numerous; styles are filiform and numerous. The berries are spherical to oblong and smooth. The flowering period is June-July, and the fruiting period is September.

[Habitat distribution] Ecological environment: Growing in mountain thickets or forests at an altitude of 1900m.

[Chemical composition] The root contains ursolic acid, oleanolic acid, succinic acid and dancosterol. The whole herb contains actinidine. Leaves contain chlorophyll. Lutein, carotene, potassium, sodium, etc. The leaves also contain quercetin-3-O-[α-rhamnopyranosyl-(14)-rhamnopyranosyl-(1-6)-β-galactopy-ranoside], kaempferol-3-O-[α-rhamnopyranosyl-(1-4)- rhamnopyranosyl-(1-6)-β-galactopyra-noside], etc.

[Pharmacological action] Intramuscular injection of 0.2 g/kg of the water-soluble component of Actinidia arguta root for 8 consecutive days has a significant inhibitory effect on mouse cervical cancer 14 (U14). It can promote lymphocyte transformation of C3H mice in vitro and enhance the cytotoxic effect of natural killer (NK) cells of these mice on 125I-dUrd-labeled U14 target cells in vivo. In addition, it can inhibit the production of hemolysin in C57 mice in vivo. These results indicate that the drug has the effects of resisting mouse U14 solid tumor, enhancing cellular immunity and inhibiting humoral immunity. Its anti-tumor effect may be partly related to its promotion of lymphocyte transformation and enhancement of NK cell activity. Actinidia arguta stem polysaccharide 70-560 μg/ml stimulated mouse spleen cell proliferation in a dose-dependent manner in vitro and enhanced the responsiveness of spleen cells to concanavalin C (C0nA) stimulation. The polysaccharide alone cannot induce IL-2 production, but can enhance the IL-2 content in the supernatant of Con A-induced spleen cell culture. After subcutaneous injection of 150 mg/kg of the polysaccharide for 9 consecutive days, the spontaneous transformation of spleen cells, the proliferation of lymphocytes, the proliferation response stimulated by Con A and the production of IL-2 were significantly higher than those of the control group. This shows that this polysaccharide has a positive regulatory effect on cellular immunity.
