How often should I eat Gastrodia elata? How to plant it? Can there be side effects if you eat too much?

Gastrodia elata is generally dug in winter and spring, and the quality is good for those who pick it in winter, and the quality is not as good as that for spring. Many friends do not know how often it is better to eat Gastrodia elata, and many farmers begin to plant Gastrodia elata, but their income is depressed due to improper methods. Then let me introduce you to the planting techniques of Gastrodia elata.

Planting techniques of Gastrodia elata

I. selection and preparation of land

It is appropriate to choose gentle slope land and valley gully land rich in organic matter for planting, and the soil quality is loose loam, well-drained sandy loam or sandy soil, especially wasteland. Soil PH5~6 is suitable. Avoid clay and waterlogged waterlogged land, avoid stubble. In addition, Gastrodia elata can be planted in air-raid shelters, caves, basements and other places.

II. Methods of reproduction

1. Tuber propagation: planted in winter or spring. The inoculation rate of Gastrodia elata planted in winter is high and grows fast, and the time is in November. Spring is planted from March to April. The bacterial bed should be cultivated before planting. The tree species suitable for the growth of Armillaria mellea are commonly used in Fagaceae, such as green stem, mistletoe oak, cork oak, chestnut and so on, and the broad-leaved trees with thick bark, hard nature and strong rot resistance are better. The selected wood is sawed into sticks 40-50 cm long and the bark is cut into fish scales. In the selected plot, 2-3 months before planting, dig a cellar with a depth of 25 cm, a width of 60 cm and a length depending on the topography. The loose soil at the bottom of the pit is leveled, a layer of dry leaves or humus soil is laid, and the treated new stick is separated from the wood with Armillaria mellea (commonly known as fungus). The distance between the two adjacent rods is 6-7 cm, and the branches of some broad-leaved trees can be sandwiched in the middle. Fill the gap with humus soil to prevent contamination by miscellaneous bacteria, and then cover the soil 3-4 cm. The second layer is placed in the same way, and the soil is covered with 10 cm. Keep the cellar moist, cover with weeds to shade, cool and moisturize to make Armillaria mellea grow normally, that is, the adult bed. The tubers without disease spot, frost injury and decay were selected for planting, separated in size and cultivated separately. When planting, put the seed hemp parallel in the ditch between the bacterial sticks, close to the bacterial sticks, fill the gap with humus soil, and then cover it with 3 cm, so that you can not see the bottom fungus material. The second layer is planted in the same way, and finally covered with 10-15 cm, covered with a layer of leaf weeds to keep the soil moist and thicken the soil layer during overwintering to prevent frost damage.

If it is cultivated in artificial bacterial bed and plastic bag, the seed hemp is white flax and rice flax, which can be cultivated from November to April of the following year due to the use of artificial temperature control.

2. Seed propagation: select Gastrodia elata with a weight of more than 100 grams, plant along with picking according to the above method, prevent sunlight when heading, and carry out artificial pollination when flowering. The time of pollination can be chosen at about 10:00 on a sunny day, when the edge of the cap appears slightly. After pollination, the ear is wrapped in a plastic bag, and when a small amount of seeds are scattered from the lower fruit, it will be harvested with ripening from the bottom to the top. As the seed life of Gastrodia elata is short, the capsule picked should be sown in time. When sowing, take out the fungus material in the upper layer of the fungus bed, pick out the soil on the lower fungus material, scatter the withered and wet leaves on the lower fungus material, flatten it slightly, spread the seeds evenly on the leaves, cover a thin layer of moist fallen leaves, sow the second layer of seeds, cover the soil with 3 centimeters, cover a layer of moist leaves, put them into the soil layer fungus, and finally cover the soil with 10 centimeters of soil. For example, 10 fungi per cellar can sow 810 capsules, and each capsule has about 30,000 seeds, which can be planted properly, some Arrow hemp, white hemp, seed hemp and a large number of rice flax can be received in the next autumn, which can be used as tuber propagation.

III. Field management

Gastrodia elata should be carefully managed after cutting, and human and animal trampling is strictly prohibited. Thicken the soil and cover the leaves against freezing before overwintering; during the high temperature period from June to August, we should build a shed or intercropping tall stalk crops to shade, clear the drainage ditch before the rainy season, and remove stagnant water in time to prevent tubers from rotting. Spring and autumn seasons, should accept the necessary eye exposure, in order to maintain a certain temperature.

IV. Pest control

1. Disordered root disease

There are two reasons for the occurrence of disorderly root disease: one is that miscellaneous bacteria invade the roots of Gastrodia elata, and the other is that too much Rain Water during the growing period makes Gastrodia elata root disorder.

Prevention and cure method: choose the ground planting Gastrodia elata with good drainage. The fungus material has no miscellaneous bacteria infection, and the gap between the fungus materials should be filled up. Always pay attention to drainage.

2. Grub

The larvae bite off the stem or eat the hemp root, resulting in a broken stem and a hole in the root.

3. Mole cricket

Adults and nymphs harm the stem of Gastrodia elata and make tunnels underground, and the cross section of the injured Gastrodia elata is in the shape of hemp filaments.

Control methods: the above two diseases are trapped and killed by light, or irrigated with 1000 times of 90% trichlorfon or 75 times of phoxim EC. Poison bait was trapped and killed with 0.025 kg of chlordane EC mixed with 5 kg of fried wheat bran and an appropriate amount of water and sprinkled in the field or border in the evening.

In general, Gastrodia elata is not suitable for daily consumption. After all, Gastrodia elata is a kind of traditional Chinese medicine, and it is easy to have some side effects if you eat too much. Let's take a look at it in detail.

Is there any side effect of eating Gastrodia elata every day?

There are side effects.

Although Gastrodia elata has many effects, Gastrodia elata itself has certain toxic and side effects. Taking Gastrodia elata every day will make toxins accumulate and cause toxic side effects.

1. Allergy

Gastrodia elata contains gastrodin, vanillin and other ingredients, belongs to allergen, Gastrodia elata may have allergic reactions, dizziness, nausea and vomiting, chest tightness, skin papules with itching, urticaria, allergic purpura may also be caused by allergies, individual face or whole body edema, or even hair loss.

2. Poisoning

Gastrodia elata has certain toxic and side effects. If you eat too much, you may be poisoned. The general toxic dose is more than 40 grams, and the poisoning incubation period is 1 to 6 hours, which can cause acute renal failure, heartbeat and respiratory acceleration and even coma.

How often should I eat Gastrodia elata? How much should I eat at a time?

Gastrodia elata can promote blood circulation, analgesia and calm the mind, in general, it can be eaten twice a week, but to play a good role in adjuvant treatment, it still needs to be taken many times in order to have an effect, and the taking time should not be too close to avoid poisoning.

Gastrodia should not eat more, not more than 40 grams at a time, if it is fried soup, it is best to control at about 3-10 grams, if it is Gastrodia powder, the dosage is even less, generally about 2 grams at a time.
