Ginseng has a history of 1000 years in China, and can be used for cooking and medicine.
According to legend, when Emperor Kangxi came to visit incognito, he spent the night in a farmhouse. After accidentally eating this vegetable, he was full of praise. Because it was born in the soil and shaped like a worm, it was named "Cordyceps sinensis" and was introduced into the palace, which was well known to the public.
The following small series will talk about this ginseng.
1, the value of ginseng
(1) nutritional value
Rehmannia glutinosa is rich in nutritional value.

Rehmannia glutinosa also has good medicinal value and can be used as medicine after drying. Its stems and leaves have the functions of promoting blood circulation, diuresis, dredging menstruation, nourishing yin and moistening dryness, regulating blood lipid, benefiting joints, nourishing qi and blood, and treating women's weakness and pallor.
Many functions of rhizome are equivalent to Cordyceps sinensis.
Rehmannia glutinosa belongs to rhizome crops, but its stems and leaves can also be eaten. Young stems and leaves can be picked in spring and summer for cooking and cold salad. The main edible roots can be dug from late autumn to next spring, with crisp taste, fried, soup and pickled vegetables.
But also has a good health care function, which can refresh the mind, stimulate appetite and strengthen bones and muscles.

3. Planting techniques of Glehnia littoralis
Ginseng is widely distributed in China, and it is still in the wild to a great extent, mainly distributed in Northeast China, Hebei, Shaanxi, Sichuan, Hunan, Hubei, Jiangsu and other places.
The most important thing is that this crop is very easy to grow, with strong adaptability, cold resistance, heat resistance, drought resistance and humidity resistance, and basically no pests and diseases. After planting, there is basically no need for management, and the underground part can withstand the low temperature of -35℃ at the lowest, with strong rooting ability. Generally, after planting, a ginseng can naturally multiply to hundreds a year, but as long as it is not completely dug up and left in the soil, it will stay in the next year.
Of course, if you want to plant in the field, it is also possible, because it has strong adaptability, so I will simply say that the planting row spacing is 40-50 cm, the plant spacing is 10 cm, the ditch depth is 10 cm, and the seeds can be planted in autumn, east and spring. Loose sand soil is the most suitable.
This is the introduction of Gleditsia sinensis root. In particular, I want to remind my friends that Gleditsia sinensis can't be eaten raw. Whether it is used as medicine or as food, it should be cooked before eating, because raw saponin has a strong spicy taste. If eaten raw, it will stimulate the stomach and endanger your health.
