Iron stick yam is one of the varieties of Dioscorea opposita.

Iron stick yam can be divided into two types due to different soil qualities:

1. Cropland iron stick yam: It grows naturally in the crop field, and the growth environment is relatively harsh. Because the soil is hard and viscous, it looks crooked. Although it is not very beautiful, it belongs to iron stick yam, which has good taste and high nutritional value and is recognized by more people.

2. Sand iron bar yam: It is planted on sand, and the yam on sand is generally longer and straighter than the yam on loam. Because the sandy land is soft and the yam in the sandy land is moist, its taste is not as good as that in hilly land, and its nutritional value is slightly lower than that in hilly land.

However, the nutritional value of yam is still much higher than that of ordinary yam or foreign yam.

Third, Chinese yam-efficacy.

1, spleen and stomach, help digestion

Yam contains amylase, polyphenol oxidase and other substances, which is beneficial to the digestion and absorption function of the spleen and stomach. Blindly nourishing the spleen and stomach is a dual-purpose product of medicine and food. Both spleen yang deficiency and stomach yin deficiency can be eaten. Clinically, it is often used with Weichang Decoction to treat spleen and stomach weakness, anorexia, fatigue, diarrhea and other symptoms.

Yam contains saponin and mucus, which can lubricate and moisten dryness, so it can benefit lung qi, nourish lung yin and treat lung deficiency with excessive phlegm and persistent cough.

Yam contains a lot of mucin, vitamins and trace elements, which can effectively prevent the deposition of blood lipids on the blood vessel wall, prevent heart disease, and achieve the effects of benefiting the heart, calming the nerves and prolonging life.

Four. Yam-taboo

Who can't eat?

1, constipation

Yam is rich in starch, and patients who are prone to constipation should stay away from or eat less yam. Because yam is hot and warm food, letting secret patients eat yam is tantamount to adding fuel to the fire.

2. People who love hot pot

Many people like to eat spicy hot pot, but spicy hot pot is a spicy thing that gets angry. Adding yam when eating hot pot will make people get angry. This leads to dry throat, sore throat and acne.

3. People with diabetes should not eat more.

Although yam contains mucin, it has the function of lowering blood sugar, but yam is a rhizome food with high starch content. If you eat too much, it will not lower your blood sugar, but will lead to an increase in your blood sugar. Therefore, diabetics should not eat too much yam at a time. If some patients prefer to eat yam, then the amount of staple food should be reduced appropriately, otherwise it will be counterproductive.

4. Prostate cancer patients and breast cancer patients

Diosgenin contained in yam can synthesize hormones such as testosterone and estrogen in human body. Therefore, it is not suitable for male prostate cancer patients and female breast cancer patients.
