Why Gongjindan·Gyeongokgo over Red Ginseng?
Dongui Bogam contains no mention of red ginseng

Red ginseng was created for long-term storage when exporting Korean ginseng to China, made by repeatedly steaming and drying ginseng to prevent decay over extended periods.

Side Effects of Ginseng 
人參動肺火凡吐血久嗽面黑氣實血虛陰虛之人勿用代以沙參可也
Ginseng stirs lung fire, so it should not be used for those who spit blood, have chronic coughs, dark complexion, excessive qi, blood deficiency, or yin deficiency. Instead, Adenophora (Radix Adenophorae) should be used as a substitute.

Ginseng and red ginseng have warm properties, so people with excessive body heat who take them for extended periods may experience insomnia, dizziness, skin itching, spots, allergies, loss of appetite, indigestion, constipation, diarrhea, and sex hormone-related symptoms such as breast pain, breast swelling, vaginal bleeding, and amenorrhea.


Psychiatric side effects include mania, excessive euphoria,

and cardiovascular side effects include elevated blood pressure, tachycardia, heart palpitations, and chest tightness.

Especially students and pregnant women

should be more cautious when taking them.

In Europe, the daily dosage of red ginseng has been limited to 2g.

"Is the ginseng in Gyeongokgo safe?"

Gongjindan and Gyeongokgo are 

not single herbs

but combinations of multiple medicinal herbs that balance their effects.

They are optimal combinations that enhance effectiveness

while eliminating side effects,

which is why they have been beloved 

for over a thousand years.

Why Gongjindan·Gyeongokgo over Red Ginseng?
Red ginseng is not found in Donguibogam

Red ginseng was manufactured for long-term storage when exporting Goryeo ginseng to China,

and was made to prevent decay for extended periods by repeatedly steaming and drying the ginseng.


Side Effects of Ginseng
人參動肺火凡吐血久嗽面黑氣實血虛陰虛之人勿用代以沙參可也
Ginseng stirs lung fire, so it should not be used for people who vomit blood, have chronic cough, have a dark complexion, excess qi, blood deficiency, or yin deficiency. Instead, it is better to use Adenophora root (Sasam) as a substitute.



Ginseng and red ginseng have warm properties, so when people with excessive body heat take them for long periods,

they may experience insomnia, dizziness, skin itching, spots, allergies, loss of appetite, indigestion, constipation, diarrhea, and

sex hormone-related symptoms such as breast pain, breast tenderness, vaginal bleeding, and amenorrhea.


Psychiatric side effects include mania and excessive euphoria,

while cardiovascular side effects include elevated blood pressure, tachycardia, palpitations, and chest tightness.

Students preparing for exams and pregnant women should be especially careful when taking it.

In Europe, the daily dosage of red ginseng has been limited to 2g. 


 "Is the ginseng in Gyeongokgo safe?"

Gongjindan and Gyeongokgo balance their efficacy by combining multiple medicinal herbs rather than using a single herb.

As the optimal combination that enhances effects while eliminating side effects, 

they have been cherished for over a thousand years.
