Sweet and frozen kudzu weather

Chrysanthemum originated in China and has been domesticated for thousands of years.

I like cold, cold, growth temperature 18-2 1℃, underground roots are drought-tolerant, and waterlogging is the most taboo. I like high terrain, deep soil, rich humus, loose and fertile soil with good drainage. It can grow in slightly acidic to slightly alkaline soil. And Ph6.2-6.7 is the best. As a short-day plant, it grows nutritionally under the long sunshine of 14.5 hours every day. Darkness above 12 hours per day and night temperature of 10℃ are suitable for flower bud development.

Edit the practice of this section

Chrysanthemum likes places with cool climate, plenty of sunshine and good ventilation. Cold-resistant and frost-resistant, afraid of extremely hot rain and waterlogging. It is best to plant in neutral soil rich in humus.

Chrysanthemum has strong adaptability, vigorous growth, easy cultivation and simple management. Propagation is mainly based on cutting and grafting. As people say, plants are divided in March, transplanted in April, grafted in May and squeezed in June. The methods are as follows:

Division method: dig out all the roots of the plant, divide 1-3 buds into a nest according to the number of tillers, plant them in the whole flower bed or flowerpot, water them enough and shade them, and they can survive for 5- 10 days. The seedlings thus propagated are robust, fast-growing and unchanged.

pharmacological action

1. Effects on cardiovascular system;

Chrysanthemum decoction and alcohol precipitation preparation can significantly dilate isolated rabbit coronary arteries and increase coronary flow. Injecting 1g crude drug into the constant pressure perfusion solution near the cardiac catheter can increase the coronary flow by about 62% and slow down the heart rate by about 20% in 2 minutes. High dose can also increase coronary flow by about 40% and myocardial oxygen consumption by 27% on average. It can alleviate the ST segment depression of ischemic electrocardiogram caused by electrical stimulation of rabbit central nervous system, and the heart rate has no change or slowdown, which is basically consistent with the experimental results of isolated rabbit heart. It can also increase the coronary flow and myocardial oxygen consumption of isolated hearts of rabbits with experimental coronary atherosclerosis. Chrysanthemum water extraction and alcohol precipitation preparation was extracted with ethyl acetate and chloroform and divided into different parts, each part had the effect of increasing coronary flow. However, it is not as strong as the original preparation, indicating that chrysanthemum contains a variety of cardiac active components, which embodies the synergistic effect on the heart. In the study of phenolic components of Chrysanthemum morifolium, it was found that the phenolic parts of Chrysanthemum morifolium could increase the coronary flow of isolated guinea pig hearts and improve the tolerance of mice to decompression and hypoxia. In a word, Chrysanthemum morifolium preparation can dilate coronary artery, thus alleviating myocardial ischemia. Although it can strengthen myocardial contractility and increase oxygen consumption, it seems that coronary artery dilatation is still dominant.

2. The role of pathogenic microorganisms:

The decoction or aqueous extract of Chrysanthemum morifolium has certain inhibitory effect on many pathogenic bacteria, as well as influenza virus PR8 and leptospira, and the MIC is about 1: 10- 1: 80. The bacteriostatic test of mice showed that the volatile oil extracted from fresh whole grass (aerial part) had strong bacteriostatic effect on Staphylococcus aureus, Escherichia coli and Shigella flexneri, but had weak bacteriostatic effect on Pseudomonas aeruginosa and no effect on pneumococcus.

3. Other functions:

After three weeks of oral administration of Chrysanthemum morifolium in rats, the activity of liver microsomal hydroxymethylglutaryl coenzyme A reductase was inhibited, and liver microsomal cholesterol 7A- hydroxylase was activated. The combination of chrysanthemum with Achyranthes bidentata, Radix Rehmanniae Preparata and Rhizoma Dioscoreae can prolong the silkworm age and affect the activity of glutathione peroxidase and the content of lipid peroxide in blood of mice. Feeding chrysanthemum powder into the stomach of rabbits can shorten the clotting time, and the effect of baking chrysanthemum powder into charcoal medicine is stronger than that of raw medicine. Chrysanthemum preparation can also inhibit the increase of local capillary permeability caused by intradermal injection of histamine, and its 10mg effect is equivalent to rutin 2.5mg.

Chemical constituents of traditional Chinese medicine

Flowers contain volatile oil, mainly borneol, camphor, chrysanthemum ketone and luteolin -7- glucoside. Cosmosiin is apigenin -7-O- glucoside [1], acacia -7-Orhamnoglucoside, apigenin, apigenin -7-O- rhamnoside, acacia -7-O- glucoside, quercetin -3-O- galactoside and luteolin-.

Usage and dosage 5 ~ 9g.

Store in a cool and dry place, sealed, mildew-proof and moth-proof.

(1) Chrysanthemum is weak in dispelling wind and good in clearing heat. It is often used with mulberry leaves to treat exogenous wind-heat and can also be used with Scutellaria baicalensis Georgi and Gardenia Gardenia to treat excess heat and irritability. Chrysanthemum can be used to treat red eyes, whether it is caused by liver fire or wind-heat. Because it can clear liver and purge heat, it is often combined with cicada slough and tribulus.

Chrysanthemum has a good effect of clearing away heat and toxic materials, and is an important medicinal material for surgery. Mainly used for the symptoms of toxic heat, sore, swelling and pain, especially for furuncle and swelling and pain. It can be taken orally or mashed for external application. Clinically, it is often used with heat-clearing and detoxicating herbs such as Viola yedoensis and Taraxacum mongolicum. Chrysanthemum can calm liver yang, and is often used with mother-of-pearl and kudzu root to treat dizziness caused by hyperactivity of liver yang.

(2) Chrysanthemum is a kind of medicine, which is mainly divided into Chrysanthemum morifolium, Huang Ju and Chrysanthemum indicum. Both Huang Juhua and White Chrysanthemum have the effects of dispelling wind and heat, calming the liver and improving eyesight, and clearing away heat and toxic materials. White chrysanthemum is sweet, slightly weak in clearing heat, and better at calming the liver and improving eyesight; Huang Juhua tastes bitter and has strong heat dissipation, and is often used to evacuate wind and heat; Chrysanthemum indicum tastes bitter, and has strong heat-clearing and detoxicating effects. The stems and leaves of Chrysanthemum indicum have similar functions to flowers, and are effective for both oral and external use. Mulberry leaves and chrysanthemum can disperse wind and heat, clear lung and liver, so they are often used for exogenous wind and heat, fever and headache, red eyes and swelling and pain. Mulberry leaves have a better effect of dispelling wind and clearing lung, so mulberry leaves are often used instead of chrysanthemum to treat lung dryness and cough; Chrysanthemum is good at calming liver yang and clearing away heat and toxic materials.

In ancient China, chrysanthemums were also called "saving flowers" and "female flowers".
