In March the seedlings, frost leaf pinch, root is practicing node, winter and early spring, dig fruit, cooked food must be gray soup, peeled, but not hemp astringent halberd person pharynx and. The stems can be DIE. The taro, arrowhead is two, arrowhead leaf, its root powder, Wu taro with stems leafless, its roots, different odor, attending is also different, and the" don't record" error by aunt as the taro, that its leaves such as taro.

[ ] the original morphology
1arrowhead, erect perennial aquatic herb. There are runners, branch end dilated into bulb. Leaves with long handle, long 20-40cm; leaf shape is extremely variable, usually hastate, generous, even the basal lobes long 5-40cm,0.4-13cm wide, apex obtuse, basal lobes short, equaling or longer and leaves, much to the two sides to carry out. Scapes with panicles long 20-60cm;3-5 flower flower for the 1 round, unisexual, lower 3-4wheel as the female, with a short stalk, and upper wheel was male, with slender pedicels; bracts lanceolate; outer tepals 3, sepaloid, ovate, apex obtuse; inner tepals 3, petaloid, white, base often purpura; stamens numerous; carpels numerous, densely into spherical. Achene obliquely obovate, diameter 4-5mm, dorsal and ventral sides of the winged; seeds brown, with small bulges. Flowering8-10.

[ ] habitat distribution
Ecological environment: born in 1 in swamps, ponds, often cultivated in paddy field.
Born in 2 in lakes, ponds, marshes, paddy fields and other waters.
Resource distribution:1 are distributed on the south.
2located in the northeast, north, northwest, East, Southern China and Sichuan, Guizhou, Yunnan and other places.
Cultivated [ ]
Biological characteristics of hi warm and sunshine of the climate, wind resistance, cold-resistant ability is extremely weak, because of aquatic plants, during the growth period, the water can not be lack of. Like organic matter rich loamy, slightly viscid cultivation in the fertile ground. Avoid continuous cropping.
Cultivation techniques with corm. Harvest date selection of head medium and full bulbs made kind, by sand storage until next spring planting date. In early autumn cold in late May to early April, appropriate planting; warm autumn warm regions, planting date can be delayed until early summer late May to late6. Dense spacing of 60cm x21cm, except for Dan Zhi, also with rice intercropping.
Field management after planting and seedling height of 15-21cm, when weeding, until late August, then2-3time weeding. During the growth period, should always maintain the shallow water, not dry. To frost blight, can only be discharged Tian Shui.
[ character ] character identification of fresh goods, showing long ovoid or ellipsoid, length 2.2-4.5cm, diameter 1.8-3.2cm. Surface pale yellow or yellow brown, some slightly purple, with vertical lines and horizontal ring Festival, festival of residual red brown scales, scales fall off and is significant, greenish yellow. Top to bud, long 5-7cm, or bud off round marks; the base obtuse or truncate, cut surface is white, more water, rich in starch. Dry goods more longitudinal or cross section into blocks, grey and white. Powder of. Gas micro, bitter sweet.

Pharmacological action [ ]
1for a variety of proteases extracted from arrowhead effect of multifunctional protease inhibitor I, II on trypsin, chymotrypsin and soothing kallikrein has obvious inhibiting effect. Medium energy equivalent to inhibit trypsin and chymotrypsin, on kallikrein inhibition is weak. On equivalent inhibition of 2mol / L trypsin, of kinin release inhibition of enzyme activity higher than that of I, but for chymotrypsin inhibition of less than1.
2 pairs of sperm in vitro fertilization in vitro experiments demonstrate, arrowhead proteinase inhibitor at a dose of 330g / ml, can inhibit the sperm acrosin activity at the top, the acrosomal protease hydrolysis of egg cell loss of the capacity of the zona pellucida, thereby allowing the sperm cannot penetrate the zona pellucida and egg, sperm fertilization effect. The experiment also proved a step, arrowhead proteinase inhibitor on human, rabbit, rat, hamster and mouse sperm acrosomal protease has obvious inhibition, and with the increase of dosage and the inhibitory effect of reinforced.
