It cannot be eaten directly, and it is toxic to a small poison.

pharmachologic effect. Antipyretic effect.

Andrographolide and neoandrographolide both have the effect of inhibiting and delaying the increase in body temperature caused by pneumococcus and hemolytic beta streptococcus, while the latter is not as strong as the former. For rabbits with fever caused by typhoid paratyphoid vaccines or rats with fever caused by 2,4-dinitrophenol, deoxyandrographolide, andrographolide, neoandrographolide, lactone, and dehydrated andrographolide all had certain antipyretic effects, among which dehydrated andrographolide had the strongest effect. Deoxyandrographolide and neoandrographolide intraperitoneal injection in suspension can delay the time of body temperature rise and weaken the degree of body temperature rise in rabbits with fever caused by simultaneous subcutaneous injection of pneumococcus pneumococcus and hemolytic streptococcal cultures.

Anti-inflammatory effect. The use of xylene and acetic acid to increase the permeability of mice ** or abdominal capillaries, and gavage of deoxyandrographolide or dehydrated andrographolide can reduce the exudation of capillary walls, compared with the control< It has a significant inhibitory effect on hemorrhagic necrotizing exudation and deoxyandrographolide caused by croton oil in rats.

Deoxyandrographolide, andrographolide and neoandrographolide at a high dose of 100 mg capsule had a significant inhibitory effect on the migration of leukocytes in rat CMC sac. The experiment also observed that these four andrographolides had different degrees of stimulatory effects on the adrenal cortex function of mice, with dehydrated andrographolides being the strongest. Andrographolide and neoandrographolide have the effect of inhibiting E. coli.

If you want to plant andrographis, you can do it between spring 2 and 3 or autumn July. After the seeds are germinated, they are planted in loose and fertile seedbeds, keeping the soil moist. During the curing period, it is necessary to control the water and temperature to stabilize the temperature between 25 and 30 degrees, so that the seeds can germinate in the later stage.

After the seeds germinate and grow leaves, they need to be given sufficient light, water and fertilizer.

Andrographis is an annual herbaceous plant of the family Andrographis in the family Andrographis, and the main mode of reproduction is sowing and propagation. Andrographis can be sown in spring 2 to 3 or autumn around July, and needs to be soaked and germinated before sowing. Choose a loose, breathable and fertile seedbed, loosen it, and sow the germinated seeds in the seedbed.

After sowing the seeds of andrographis, it is necessary to stabilize the temperature of the environment between 25 and 30 degrees. During the maintenance period, it is also necessary to keep the soil moist, and under the conditions of suitable temperature and sufficient soil moisture, the seeds of andrographis can germinate quickly. After the seeds germinate and grow leaves, they can be given sufficient light, water and fertilizer for their growth.

In the later stage, after the andrographis grows steadily, it can be transplanted into deep and soft soil. During the curing period, it can be given enough light to allow it to photosynthesize. During the maintenance period, it should be noted that the light is too strong in summer, and the andrographis seedlings are not tolerant to strong light, so it is necessary to do a good job of shading to avoid the seedlings being sunburned.

Andrographis loves moisture and is suitable for growing in humid climates. During the maintenance period, the andrographis should be given plenty of water, but it should be watered in moderation to keep the soil moist. During the maintenance period, it is necessary to fertilize andrographis in an appropriate amount, and the fertilizer is mainly compound fertilizer containing nitrogen, phosphorus and potassium, which can promote the growth of andrographis branches and leaves.

Andrographis is a relatively famous medicinal material, it is an annual herbaceous plant, and the cultivation area in the south of our country is relatively extensive. Andrographis can not only be fried as a vegetable, but also a kind of medicinal material, which has the effect of clearing heat and detoxifying, reducing inflammation and relieving pain. So how is andrographis grown?

1. Land selection and land preparation. To choose sufficient fertility, loose soil, good permeability and heat preservation of the acidic soil, the selection of good soil needs to be carried out in a timely manner, the depth of land preparation can not be less than 30 centimeters, in the land preparation needs to pick up all the weeds in the soil, after ploughing enough amount of base fertilizer, and then do a good job of disinfection.

2. Sowing seeds at the right time. When choosing seeds, we must choose excellent seeds that have no diseases, good genes, and no cracks and wounds, and try to avoid rainy weather at the time of sowing, and determine the number of seeds according to the planting area. In sowing, the seeds should be treated, the seeds should be cleaned, and then they should be mixed in the firewood ash, because the firewood ash can promote the germination of seeds and improve the speed of their growth.

After mixing, the seeds are sown on the soil by sowing, and then covered with a layer of about one centimeter of soil after sowing. The main purpose of spraying with double rose agents and other agents is to reduce the incidence of cataplexy and blight, and then do a good job in water and fertilizer retention of the soil.

3. Field management. After sowing, when the seedlings grow to a certain extent, they should be transplanted in time to maintain a good planting density. After transplanting, it should be watered in time to promote the rooting and development of the roots of the seedlings, and then about 21 days can be carried out a tillage, and it should be carried out together with additional fertilizer when tillage.

When topdressing, you must apply more nitrogen fertilizer, and you can use farmhouse fertilizer after full decomposition. It is very important to manage in the summer, andrographis is the key to grow in the summer, at this time we need to increase the number of topdressing and watering, which is conducive to the good growth of the plant, when the plant grows taller, we need to cultivate the soil in time to prevent the phenomenon of lodging.

4. Prevention and control of pests and diseases. Standing blight and cataplexy are the main diseases of andrographis, and standing blight usually occurs when the seedlings grow about two leaves. After the onset of the disease, it is necessary to control the frequency of watering to prevent the soil from being too wet, and then use carbendazim and other agents for prevention and control.

Pay attention to the ventilation of the garden, control the surrounding environment, especially the temperature, the temperature is too low will hinder the growth of the plant, strengthen the permeability of the garden, timely uproot the diseased plant, and do a good job of pruning and pruning. Reduced morbidity conditions, reduced probability.

When the andrographis grows to the flowering period, it can be harvested, and it is necessary to use a knife to harvest 2-3 nodes of the roots, and it can be dried after harvesting. Planting andrographis can be harvested twice a year, and the yield per mu can reach 500-800 kg per year.

Hello. Andrographis is an annual rejuvenating herb that wilts and dies at the end of the planting season and decays to become organic fertilizer. If you want to grow other crops on the same plot, consider clearing the remaining plants, roots and fallen leaves, and then applying the right amount of organic and mineral fertilizer to improve soil fertility.

In addition, depending on the crops being grown, factors such as soil pH, moisture content, and aeration may need to be adjusted to ensure the growth and development of crops. It is best to carry out scientific crop rotation according to the ecological environment requirements of different crops to maintain the health of the soil and the stability of the yield.

Andrographis is an invasive plant with fast growth, strong vitality and strong fecundity. Because its root system is abundant and the root system can nourish the surrounding plants, it is difficult for plants and trees to survive in areas where andrographis has been planted. Therefore, it is not recommended to continue to grow other crops on the land where the andrographis has been planted, but the andrographis should be removed first, the root system should be cleaned, and then the land should be maintained so that the land can be fully restored.

If you need to grow other crops on the land where andrographis grows, consider using some shade-tolerant plants and improving the soil. For example, in the case of andrographis that has a short growth time and is not dense, some lawn or ground cover plants can be planted; Or add a lot of organic fertilizer to the soil, so that the soil can be effectively improved, increase soil fertility, and be more conducive to the growth of other plants. However, it should be noted that in particularly serious andrographis invasion areas, it is recommended to cut off the photosynthesis of andrographis first, and carry out root removal treatment, and wait until the seeds and roots of andrographis in the soil are completely removed before planting other crops.
