Seasoned bracken with green vegetables

The Sansam family likes bracken, so they often eat it, but during the Chuseok holiday, they boiled bracken muknamul and seasoned bracken, and some were cut into small pieces to put in mung bean pancake.

When I went down to the countryside last spring, I bent the e-mail bracken, boiled it, dried it, and made it into a few keys. I think I bent it a lot because it’s enough to send a box of 1 kilogram to my sister-in-law and sister.


The current Korean name bracken is based on the Joseon Botanical Hyangmyeong Collection (Joseon Museum Research Association, Jeong Tae-hyun et al. 3, 1937). It is said that Gosa-ri became Gosa-ri due to the omission of 에서 from the name of Goksari in Chinese characters. 絲里는 is the name derived from the dried shape of the stem when the sprouts of Gosa appear, and the thread-like white thing is attached to the plant body.


Eastern brakenfern

perennial plant of ferns and ferns

The scientific name Pteridium aquilinium (L.) Kuhn var. latiusculum (Desv.) Underw. ex A. Heller

The genus name Pteridium is derived from the Greek word pteron, which means wing, and is associated with Iksangbokyeop, and the species name aquilinum means “poisonous, curved”, and the variant name latiusculum means “pretty wide”.

the effect of bracken

The young leaves are boiled and dried, then eaten, and starch is collected from the roots, and in oriental medicine, the young leaves are called gwal and the root of bracken is called gwalgeun.

It is recorded that dried and powdered bracken’s roots are effective for parasites, and American Indians ate them raw as a treatment for bronchitis.

Gosari is a calorie food per 100g, which is rich in dietary fiber and helps eliminate constipation.

bracken has the effect of improving diuretic effects and edema symptoms. In addition, since it has an antibacterial effect, itching caused by eczema can be alleviated by mixing fern-burned powder with garlic juice and attaching it to the affected area.

bracken is particularly rich in potassium and phosphorus among minerals, and when bracken is dried, minerals such as potassium, magnesium, and iron become more abundant. It protects the skin and mucous membranes, is good for skin beauty, clears the head, and strengthens teeth and bones.

It is good for children, pregnant women, and the elderly by preventing anemia and osteoporosis, and is effective in facilitating metabolism and discharging waste from the body. It is also effective in increasing immune function and reducing cholesterol and preventing arteriosclerosis.

Gwol, a young leaf of bracken, has the effect of blue fever, yunjang, Ganggi, and Hwadam. It treats sikkyeok, qigyeok, and jangpung fever. In addition, the lack of intestines is compensated, the energy blocks the meridional musculoskeleton, and the poison (contagious developing substance) is treated. In addition, it has the effect of causing a burst of heat and transferring waterways.

Geolgeun, the root of bracken, is dug up in autumn and winter, washed clean, and dried in the sun. It has the effect of blue fever and foreign habit.

Forsythia toxicity and side effects

There is a myth that “eating bracken weakens your energy.” As supporting this, the Food Maincho recorded, “It weakens the strength of the legs, causing difficulty in walking, depriving the yang and causing the penis to shrink.”

In addition, in Bonchomongjeon, “Yanggi weakens and legs and knees weaken.” It says, “A side dish that should never be eaten too much.”

Even Donguibogam recorded that “If you eat a lot, the energy of the sheep decreases and your legs become weak and you cannot walk.” These side effects may be the side effects of raw fangs.

The side effect of losing strength in the legs is related to thiamine deficiency. Raw ferns contain thiamine, or thiaminase, a vitamin B1 degrading enzyme. Especially when it’s a new year. Thiamine promotes human energy metabolism and is a necessary nutrient for nerve and muscle activities.

The representative disease that appears when this is insufficient is keratosis. Depending on the invading organ, sensory deterioration, symptoms of loss of strength in the limbs, cardiovascular disease, eye movement abnormalities, walking abnormalities, and memory disorders appear.

There is no clear study that thiamine is related to sexual desire and sexual function. However, experts speculate that lack of this ingredient can lead to fatigue and depression, which can result in poor sexual vitality.

For reference, studies have shown that sulfutiamine, a thiamine-induced compound, improves sexual desire and is effective in erectile function. Therefore, it is not only vain that bracken reduce sexual desire. However, thiaminase is easily removed by simply immersing ferns in water.

Removal of bracken toxicity found in old literature

According to the method of storing bracken (Janggul) in a mountain song written by Jeon Soon-ui, who was a doctor during King Sejong’s reign, “Boil the soft bracken and mix it with dry ash and dry it. Wash the ash, dry it in the sun, and store it. It is said to be softened by soaking it in boiling water when using it.

In this sentence, we can find out two main processes of bracken processing. First, it means to boil ferns and mix them with dry ash to make them alkaline, and if you blanch them in a medium-sized bath (baking soda, sodium carbonate) and leave them in water for more than 5 hours, the astringency will fade, the water will turn purple, and the fern will soften.

This is because creating weak alkaline conditions increases the removal of carcinogens from ferns by more than 25% rather than just blanching them in water.

Second, in the text, it is said to be dried and stored in the sun to remove vitamin B1 degrading enzyme in ferns. This is because enzymes are decomposed by heating, but they are more completely decomposed through a drying process that removes moisture.
