What kinds of motherwort are there?
There are two kinds of motherwort: motherwort and motherwort.
Leonurus japonicus: annual or biennial herb with a height of 60- 100cm. Stems erect, quadrangular, and puberulent. Leaves opposite; Various leaf shapes; The petiole is 0.5-8 cm long. The basal petiole of annual plants is long, the leaves are slightly round, the diameter is 4-8 cm, and there are 5-9 lobes with 2-3 blunt teeth, and the base is heart-shaped; The leaves in the middle of the stem are short-stalked, 3-lobed, the lobes are nearly lanceolate, the central lobe is often 3-lobed again, and the lobes on both sides are 1-2-lobed again. The width of the last section is usually greater than 3mm, the apex gradually tapers, and the edge is sparse and serrated or close to the whole edge. The uppermost leaves are undivided, linear, subsessile, green above, strigose, light green below, sparsely pilose and glandular spots. Cymes axillary, with 8- 15 flowers; Bracteoles acicular, pedicellate; Calyx bell-shaped, puberulent outside, with 5 teeth at the apex, spiny, the lower 2 teeth longer than the upper 2 teeth, persistent; Corolla is lip-shaped, reddish or purplish red, 9- 12mm long, externally pilose, with the upper lip almost as long as the lower lip, the upper lip is oblong, the edge is ciliate, the lower lip is 3-lobed, and the central lobe is large and inverted heart-shaped; Stamens 4, strong enemy, inserted in the middle of corolla, filaments sparsely scaly, anthers 2-loculed; Pistil 1, ovary 4-lobed, style filiform, slightly longer than stamens, stigma 2-lobed. Nutlets are brown, triangular, broad and flat at the top, wedge-shaped at the base, 2-2.5 mm long and about 65438 0.5 mm in diameter. The flowering period is from June to September, and the fruiting period is 7-65438+1October.
2. Motherwort: an annual or biennial herb with a height of 80 cm. Stem erect, quadrangular, strigose, leaves opposite. The petiole is 0.5-5 cm long; The lowest leaf of the stem caducous, the middle leaf is ovate, palmately 3-lobed, about 5cm long and 4cm wide, and the lobes are whiplike, and then pinnately split into 3-lobed linear lobules, usually1-3 mm wide; The uppermost leaves are obviously 3-lobed, lobules are linear, subsessile, green above, sparse cymes axillary, flower-shaped; Pediceless; Bracteoles acicular, shorter than calyx tube, strigose, calyx bell-shaped, externally pilose, apex 5-toothed, spiny, upper 3 teeth shorter than lower 2 teeth, persistent. Corolla lip-shaped, red or purplish red, long 15-20 mm, densely villous outside, upper lip about14 longer than lower lip, oblong from lip, entire, lower lip 3-lobed, central lobe oval; Stamens 4, strong, inserted in the middle of corolla, filaments sparsely scaly, flowers 2-loculed; Pistil 1, ovary 4-lobed, style filiform, slightly longer than stamens, stigma 2-lobed. Nutlets are brown, trigonous, broad and flat at the upper end, wedge-shaped at the base, and about 2.5 mm long. Leonurus heterophyllus blooms from June to September, and the fruiting period is 7-65438+1October.
What is the composition of motherwort granules?
Main ingredients: motherwort. The auxiliary material is sucrose.
The function of motherwort:
1. Effects on uterus: Leonurus japonicus decoction, ethanol extract and Leonurine have exciting effects on isolated uterus of rabbits, cats and other animals.
2. Cardiovascular effect: Leonurus japonicus can significantly increase the coronary flow of isolated guinea pig hearts and slow down the heart rate. Intravenous injection of motherwort preparation can obviously increase coronary artery flow, reduce coronary artery resistance, slow down heart rate, reduce cardiac output and left ventricular work in anesthetized dogs.
3. Anti-platelet aggregation and anti-thrombosis: In vitro experiments show that Leonurus heterophyllus and its extract can antagonize platelet aggregation induced by ADP in normal animals. In vivo experiments have also proved that Leonurus japonicus can significantly reduce the total number of platelets in peripheral circulation and platelets and their aggregates in capillaries of alveolar wall. Leonurus japonicus has obvious dissolving effect on red thrombus in pulmonary circulation of rabbits. In addition, motherwort can also enhance the cellular immunity of the body.
4. Other effects: The alkaline subcutaneous injection of Leonurus japonicus has central inhibitory effect, and the MLD is 0.4-0.6g/kg. Intravenous injection of leonurine 1mg/kg in rabbits significantly increased urine output. Leonurine can hemolyze rabbit blood suspension at high concentration. The alkaline aqueous extract of Leonurus japonicus was diluted by test tube method (1:1:1:kloc-0/0), which had inhibitory effects on Mucor Xu Shi, Microsporum wool, Epidermophyton rubrum and Nocardia stellata. Motherwort decoction was prepared by plain paper method, which had inhibitory effect on Escherichia coli and Shigella dysenteriae.
Motherwort granules are used for promoting blood circulation and regulating menstruation. Used for irregular menstruation caused by blood stasis, with symptoms of less menstrual flow. The main component of motherwort granules is motherwort. From the above introduction, I believe everyone has understood its function.
