[Other names] Wild taro, rock taro

[Source] Medicinal material source: The tuber of Colocasia esculenta of the Araceae family.

[Original form] Colocasia esculenta, perennial herb. The tuber is spherical, 1-2 cm in diameter, and has a yellow-brown skin. Scale leaves are numerous, long-lanceolate, 2-3cm long, often fibrous and torn, persistent; petiole is cylindrical, green, 25-40cm long, with sheath in the lower 1/3; leaf blade is leathery, dark green on the surface, light green or bluish-purple on the back, ovate or oblong-ovate, 8-20cm long, 7-12cm wide, with sharp tip and cordate base. The inflorescence stalk is cylindrical, 6-10cm long, and light green; the spathe tube is green, oblong-ovate, 1.2-1.5cm long, 1cm thick, and the two sides of the eaves are light yellow or yellow-green. It is erect at first, and then tilted backward when flowering. The lower 1-2cm is swollen into a sphere, half-expanded when flowering, constricted upward, and genu-flexed to transition into a long flat boat-shaped eaves, 13-19cm long, 1.8-2.5cm wide when flat, oblong-lanceolate, and the apex is long and gradually pointed; spadix, the female inflorescence is light green, 6-8mm long, the female flower ovary is green, without style, and the stigma is oblate; the sterile male inflorescence is rhombus-shaped or rectangular, flat; the fertile male inflorescence is short rod-shaped, bluish-purple, 1cm long, 4mm thick, and the pollen is yellow. Flowering period is from May to July.

[Habitat distribution] Ecological environment: Growing on limestone in dense forests or shrubs at an altitude of 1000-2800m.

[Pharmacological action] 1. Effect on immune function: 1.1. Effect on IgE antibody level: Wild taro flower water extract was administered to rats at a dose of 20 g (raw drug)/kg for 4 consecutive days. The serum IgE antibody titer was determined and the result showed that the increase in serum IgE level after injection of Trichosanthes kirilowii was significantly inhibited. In addition, using an in vitro allergic histamine release test, it was found that the percentage of allergic histamine release in the lung tissue was half of that in the control group, indicating that the IgE antibody level in the lung tissue also decreased. The inhibitory effect still exists in adrenalectomized rats, indicating that it is not produced indirectly by stimulating the adrenal glands to secrete adrenaline or adrenal cortex hormones, but is a direct effect. In addition, 10g (crude drug)/kg of wild taro flower water extract and 20g (crude drug)/kg of root, stem and leaf water extract were administered to rats for 10 consecutive days, and serum was collected for passive skin allergy test (PCA). The inhibitory effect of 20g/kg of wild taro root water extract (crude drug) and 10g/kg of its flower extract on serum IgE antibodies is equal to or slightly stronger than that of the flower, but the effect of stems and leaves is not obvious. In contrast, after immunizing C57BI pure strain mice with the same antigen, the serum IgE antibody levels of mice in the three dose groups were significantly higher than that of the control group at 10g/kg, 20g/kg and 40g (raw drug)/kg of wild taro flower water extract for 14 consecutive days, while the increased level in the low dose group was not lower than that in the medium and high dose groups. 20g/kg of wild taro flower water extract was gavage-administered to C57BI mice for 14 consecutive days, and blood and spleen were collected for serum (1:120) PCA and spleen (1×106 cells) heterologous inherited skin allergy test (HACA), respectively. The results showed that the serum PCA and spleen cell HACA IgE antibody levels in the wild taro flower group were significantly higher than those in the control group, and more specific IgE antibody-producing cells appeared in the spleen, which has a similar effect to PHA. In addition, there was no significant effect on the cAMP content in the spleen and thymus. However, when CFW mice were given 20 g/kg of wild taro water extract 4 days before the second intraperitoneal injection of Trichosanthes kirilowii immunization and on the second day after the second immunization, both were administered orally for 5 days. These two dosing regimens could not significantly change the secondary IgE antibody response level of CFW mice.
