How to take supplements in winter to prevent diseases

　　As the saying goes, "Winter nourishes three to nine". It’s a good time to take supplements again. Many people will choose some Chinese herbal medicines to supplement the nutrients needed by the body. Perhaps it is based on the wish of “three-nine supplements for one winter and fewer illnesses in the coming year”, or because of the popular health theory. However, there are many mysteries hidden in these nourishing Chinese medicinal materials, especially some precious Chinese medicinal materials, which are not accessible to everyone. What are the specific requirements?

　　1. Ginseng

　　(1) Types and classification of ginseng: Types of ginseng vary according to different classification methods. According to botany, it is divided into ginseng and American ginseng; according to traditional Chinese medicine processing and efficacy, it is divided into wild ginseng, raw sun-dried ginseng, red ginseng, and American ginseng; according to its origin, it is divided into Jilin ginseng, Korean ginseng (also known as Korean ginseng, and American ginseng) and American ginseng. The second classification method is the most commonly used.

　　(2) Efficacy of ginseng: Wild ginseng restores and strengthens the veins, strengthens the vitality (neutral nature); removed wild ginseng and raw sun-dried ginseng have the same effects as wild ginseng but less powerful; Korean red ginseng restores the veins and strengthens the veins, replenishes qi and generates blood (warm nature); American ginseng nourishes the lungs and reduces fire, nourishes the stomach and produces fluid (cool nature).

　　(3) Suitable crowd: Suitable for sub-healthy crowds and patients with chronic debilitating diseases. Korean red ginseng is suitable for people with a cold (Yang deficiency) constitution; American ginseng is suitable for people with a hot (Yin deficiency) constitution; wild ginseng has a milder nature and can be taken by people with general physiques. It is generally not suitable for children to take.

　　(4) Contraindications: Traditional Chinese medicine believes that ginseng cannot be taken together with hellebore, saponaria, Wulingzhi, radish, and radish seeds. Also don’t drink strong tea. For people with heat (yin deficiency) constitution, eating red ginseng can easily cause constipation, nosebleeds, and increased blood pressure. People with cold constitutions are prone to stomach pain and diarrhea when eating American ginseng. Ginseng is not suitable for people with acute illnesses such as colds, fever, and diarrhea.

　　(5) Identification of ginseng quality

　　①American ginseng is best for its uniform size, fine and clean surface, dense ring patterns, hard texture, light body, fragrant smell and strong taste.

　　②Wild ginseng depends on the "five shapes". Reed: There are dense bowl-shaped scars on the reed, commonly known as "reed bowl". Wild ginseng reeds are more slender and the reed bowl is tight. Grain: There are fine and deep spiral horizontal grains on the shoulders, and the grains are fine, deep and tight. Body: The main root is short and thick, the shoulders are wide, the body and legs are obviously separable, and there are usually two legs. Skin: The outer skin is fine, clean and tight, yellow-white or yellow-brown in color, and looks old. Beard: thin and long, sparse but not messy, with obvious bumps on the beard, commonly known as "pearl spots".

　　③Don't directly divide it into three categories: heaven, earth, and human beings. The roots are preferably thick, hard and uniform in color. It is difficult for non-professionals to identify. When purchasing, be sure to look for the brand and reputable pharmacy or company.

　　(6) How to eat ginseng and its suitable seasons

　　①Make tea: American ginseng and raw sun-dried ginseng can be cut into thin slices. Take 3 to 5g per day and brew it with boiling water.

　　②Stew and take: 1 small branch of wild ginseng (3-5g for large ones), put it into a porcelain bowl, add water and rock sugar, cover the mouth of the bowl, place it in a pot and steam and stew for 2-4 hours, and take it in three days (take it with the residue on the last day). If you want to take it again, you need to stop taking it for 7 days and then continue taking it. The stew method of Bie Zhi Ginseng is the same as above. Take it in 3 days, or take 1 stick several times. Take 3 to 5g each time, add appropriate amount of water, simmer in water for more than half an hour, then drink the juice or drink it with the dregs. Once a day, take it until it is finished. Generally, 1 stick per season is enough. You can also take an appropriate amount and stew it with chicken, duck and other meat.

　　It is better to take ginseng and wild ginseng from the beginning of winter to the beginning of spring, especially around the winter solstice.

　　2. Cordyceps sinensis

　　(1) Efficacy: warm in nature, nourishing the lungs and kidneys, and relieving asthma and cough. It has a good preventive effect on people with low immune function, especially those with reduced respiratory resistance, repeated colds, asthma, and chronic bronchitis. It is also very effective for kidney diseases such as chronic kidney disease, diabetic kidney disease, tinnitus, backache, decreased sexual function, and poor work energy.

　　(2) Traditional way of serving: Cordyceps and old duck in pot. Stew 5 Cordyceps cordyceps, a skinny old duck, some salt and seasonings. Repeat once a week.

　　3.Bird’s nest

　　(1) Efficacy: neutral in nature, moistening the lungs and nourishing yin, tonifying the middle and strengthening the kidneys. "Compendium of Materia Medica" states that it "enters the lungs to invigorate, enters the kidneys to nourish water, and enters the stomach to nourish the spleen."

　　(2) Traditional way of taking it: 1 cup of Bai Yan, soak in water for 4 hours, add wolfberry, red dates, lotus seeds, rock sugar, etc., and simmer for more than 40 minutes. Take 3 times. Repeat once a week.

　　(3) Regarding blood swallows: Because blood swallows are very rare and precious, some so-called blood swallows on the market are artificially processed from inferior white swallows and contain a large amount of nitrite, the so-called "poisonous blood swallows", which are carcinogenic. Therefore, it is best to go to regular hospitals, manufacturers or pharmacies to buy Baiyan.

　　4. Husky Toad (Rana Oil)

Ganoderma spore powder is the seed of Ganoderma lucidum and contains the essence of Ganoderma lucidum. Only 1 gram of spore powder can be collected from 1000g of mature Ganoderma lucidum, so it is relatively precious. Studies have shown that its efficacy is equivalent to 75 times that of Ganoderma lucidum fruiting bodies, and is more effective than liver protection, liver protection, prevention and auxiliary treatment of various tumors.

　　6. Polygonum multiflorum

　　It is slightly warm, nourishes the liver and kidneys, replenishes essence and blood, relieves constipation and detoxifies. It is suitable for people with kidney deficiency accompanied by constipation and premature graying of hair.
