Small signals sent by the body
For me, enduring busy days,
and for parents who are not as they used to be.
It is time to examine the current state of the body.
When fatigue persists as work and daily life accumulate.
When fatigue persists for a long time.
Feeling easily tired even during usual tasks,
and sensing a decrease in vitality.
After illness, when energy is depleted
and you want to take care of your body.
Taking care of the health of parents and myself
step by step when you want to do so.
The causes of fatigue are diverse. JAIMDANG assesses the current condition and together determines whether Gyeongokgo is appropriate.
What kind of herbal tonic is Gyeongokgo?
Gyeongokgo is a traditional Korean herbal prescription based on fresh Rehmannia root, ginseng, white Poria, and honey. The traditional method combines the herbs’ juice and powders with honey and heats the mixture in a water bath.
The character ‘go (膏)’ in the name means a thick paste form. Unlike swallowing pills or mixing powders, it is a formulation taken by scooping the instructed amount.

The Four Foundations of Gyeongokgo
02 / FOUR INGREDIENTSThe concept of traditional Korean medicine that considers the balance of energy, body fluids, and the spleen and stomach
can be read in the composition of the herbal ingredients.

An herb used in traditional Korean medicine to nourish yin and body fluids. In the traditional preparation of Gyeongokgo, juice is extracted from raw Rehmannia.
Traditionally used to replenish original energy and the energy of the spleen and stomach. In Gyeongokgo, finely powdered ginseng is blended together.
Described in traditional Korean medicine as an herb that aids the spleen and stomach and regulates water metabolism. It forms the prescription together with raw Rehmannia, ginseng, and honey.
A material that binds the juices and powders of the herbs and forms the base of the paste formulation. Confirm before use if sugar intake management is necessary.

ANTI-AGING RESEARCH
04 / ONGOING RESEARCHBeyond classical records, current research
examines the effects of Gyeongokgo on cells and organisms.
In cultured human skin fibroblasts, an increase in collagen precursors and inhibition activity of MMP-1 were observed.
Resistance to heat stress and oxidative stress was tested and related activities were reported.
In mice exposed to ultraviolet radiation, wrinkle formation and changes in collagen-related genes were observed.
This is preclinical research in cells and animals, not a clinical trial establishing benefits in people or an anti-aging effect of JAIMDANG’s product.

Please consult together so that the health status and medications of the person who will take it can be confirmed. Prescription and administration methods are guided based on the actual person who will take it.
Gyeongokgo contains honey. Please inform us of diabetes diagnosis, blood sugar control status, and medications during consultation to determine suitability and dosage.
We do not judge solely based on the feeling of having 'excessive internal heat'; we consider actual symptoms and the overall prescription composition together. Please inform us about your digestive condition, sleep, and any medications you are currently taking.
It varies depending on age, purpose of intake, and current condition. Rather than promising a fixed duration or effect uniformly, guidance is provided while monitoring progress after consultation.
Please inform us of all medications and health supplements you are currently taking during consultation. After checking the types of medicines and your health status, we will advise on whether concurrent use is appropriate. Please also consult us first if you are pregnant or breastfeeding.
Please follow the storage method and usage period provided at the time of preparation. Use clean and dry utensils, do not put back any taken-out Gyeongokgo, and close the lid after use for storage.
With a heart that cares for the health of your precious ones.
