This is a higher plant belonging to the Gastrodia Elata family and has no fine roots. The name 'Cheonma' means 'yam fallen from the sky'. It is a parasitic plant that cannot consume nutrients by itself because it has no leaves and roots. As such it can grow only by parasites in the mulberry mushroom mycelium, and does not receive nutrients from the soil. When the surrounding oak mushroom fungus is cultivated as its growth environment, it can grow as a parasitic plant and reproduces by receiving nutrition through mycelium, such as hair, having a lifespan of 2 years. People can eat Cheonma with confidence because it is grown in a 100% eco-friendly farming method that does not use any pesticides or chemical fertilizers.
The difference between 'Gastrodia Elata' and 'Dioscorea Japonica'
As is commonly known, yam (麻) is a plant of the yam family and grows through its own nutrient absorption and photosynthesis, while Cheonma (天麻) is a plant of the Orchid family and grows by parasite to mushroom fungi. The difference between Cheonma and general yam is the same as that of wild ginseng to bellflower. In other words, the appearance and the name are similar, but there is a huge difference in efficacy.
Gastrodia Elata Blume

No roots or nodes.
It's juice is not viscous.
Botanical Classification : Yam
It has roots.
It's juice is viscous.
Nutrient of Gastrodia Elata
It's sweet, bitter, salty, spicy, and sour tastes, Cheonma has a variety of tastes including mild, savory, etc.
While most foods have one or two flavors, Cheonma has various flavors and thus a greater appeal.
General Ingredients : Contains 89.8% carbohydrate and 6.2% crude protein, so the protein content is higher than that of other crops.
Amino Acids : Contains even amounts of essential amino acids, arginine and histidine, as well as 1,272 aspartic acid and 1,249 glutamic acid, containing these ingredients more than other plants.
Fatty Acids : Its fatty acids are mainly composed of unsaturated fatty acids.
Minerals : Potassium content is 1,265, which is the highest, and it is effective in regulating the physiology of the human body as it is composed of phosphorus, calcium, sodium and magnesium.
Fell before the sap rises while it is stopped (After autumn leaves fall and before shoots sprout).
Cut the hardwood at 40 cm length after moisture control is done.
Mixing the soil / Flattening soil
After mixing the soil 50~60 cm, flatten back to its original shape. This is done to use the hardwood arrangement.
Arrange the cut hardwood neatly as if laying a solid wood floor on a flattened bank.
Inoculation of Spawn
After the arrangement of the hardwood is finished, insert the Cheonma spawn one by one between the hardwoods. At this time, it is desirable to work such that the hardwood and the spawn are in close contact.
Placing Cheonma Seed
After spawn inoculation is over, place Cheonma seed around the hardwood and spawn.
Making a Ridge
After inoculation and planting Cheonma seed, cover the ridge with 15~20 cm of the soil next to it. At this time, make the shape of the ridge oval to ensure good drainage.
Covering Work (covering with rice straw)
When drainage work is complete, cover it about 5 cm or more with fallen leaves or rice straw, and cover the light-shield so that it is not blown by the wind. This has the effect of preventing drought damage or avoiding rain during the rainy season.
Cheonma is a medium-low temperature plant whose growth temperature ranges from 10 to 30℃. Its ideal growth temperature is from 15 to 25℃. For reference, it grows at natural temperatures from early spring to early winter, and there is no need to pay special attention to the temperature.
The harvest period is from November to early December or from March to April of the following year. Remove the cover of the ridge, and get rid of the ridge soil using a hoe, etc. Then harvest the Cheonma on the ridge or between the ridges. At this time, the grown Cheonma is harvested and the young Cheonma is used again as a seed. (It is possible to harvest Cheonma continuously for about 2 to 3 years, which is the period when the nutrients of the oak tree are lost)
