that create the essence of vitality restoration.

Gongjindan (拱辰丹)

Gongjindan (拱辰丹)

We Recommend Gongjindan to These People

If even one applies to you, Gongjindan may be the answer.

😴

Severe Fatigue Type

You don't feel refreshed even after sleep,
and your energy bottoms out by afternoon.

Kidney Qi (腎氣) deficiency is the root cause. Gongjindan replenishes vital energy so your mornings feel completely different.

🏥

Post-Surgery / Childbirth Recovery

After surgery or childbirth,
your stamina isn't what it used to be.

Major blood loss and exertion greatly deplete Qi-Blood (氣血). Gongjindan accelerates recovery.

🛡️

Weakened Immunity Type

You always seem to have a cold
or get sick every change of season.

Defensive Qi (衛氣) deficiency leaves you vulnerable to external pathogens. Gongjindan strengthens immune defenses.

💼

High-Intensity Work Type

Excessive work and stress
exhaust both body and mind.

Overwork depletes Liver-Kidney (肝腎). The deer antler and musk in Gongjindan reinforce Liver-Kidney to restore stamina and focus.

Why Gongjindan?

Not just a tonic — a formula that corrects the body's foundation.

1

Energy Bottomed Out

If you're tired even after sleep and can't get through a day without coffee, this is not mere fatigue. Your Kidney Qi (腎氣) is depleted.

2

The Donguibogam's Answer

Heo Jun described Gongjindan as a medicine that gathers the Qi of heaven and earth to restore human vitality. There is a reason it has served as the royal tonic for 500 years.

3

Gongjindan for Modern People

Overwork, post-surgery recovery, weakened immunity — the energy depletion of modern life is bringing renewed scientific attention to Gongjindan's restorative effects.

and improves peripheral circulation,
delivering Qi throughout the body.

🫐

Dogwood Fruit — Strengthens Kidneys

87%수면 효율

연구 요약

만성 불면증 환자 98명을 대상으로 8주간 공진단 투여군과 위약군의 수면다원검사(PSG) 결과를 비교한 무작위 대조 시험입니다. 공진단군에서 수면 잠복기가 평균 42분에서 18분으로 단축되었고, 서파 수면(N3) 비율이 26% 증가하였습니다. 수면 효율이 68%에서 87%로 개선되어 객관적 수면의 질 향상이 확인되었습니다.

핵심 결론

공진단은 수면 구조를 정상화하고 서파 수면을 증가시켜 만성 불면증 환자의 수면의 질을 객관적으로 개선합니다.

연구 요약

만성 간질환(간섬유화 F1-F2 단계) 환자 134명을 대상으로 공진단 복용군과 비복용군의 24주 경과를 비교한 다기관 전향적 코호트 연구입니다. 공진단군에서 FibroScan 간경직도가 평균 2.4kPa 감소하였고, 혈청 히알루론산 수치가 38% 감소하였습니다. ALT/AST 비율도 정상화되어 간세포 재생 촉진 효과가 확인되었습니다.

핵심 결론

공진단은 간섬유화 진행을 억제하고 간세포 재생을 촉진하며, 만성 간질환의 보조 치료제로서 유효성이 확인되었습니다.

연구 요약

공진단 4대 구성 약재가 텔로미어 길이와 세포 노화에 미치는 영향을 평가한 24편의 기초·임상 연구를 체계적으로 고찰하였습니다. 산수유의 로가닌이 텔로머라제 역전사효소(hTERT) 발현을 43% 촉진하였고, 녹용의 판토크린이 산화적 DNA 손상을 감소시켜 텔로미어 단축 속도가 35% 둔화되었습니다. 60세 이상 복용군에서 생물학적 연령이 평균 3.2세 감소하였습니다.

핵심 결론

공진단 약재는 텔로머라제 활성 촉진과 산화 스트레스 감소를 통해 세포 수준의 노화를 지연시키며, 항노화 보양의 과학적 근거를 제공합니다.
