Has enduring it every month
become your normal?

Menstrual pain is not something you have to endure.
When blood cannot flow out properly and becomes stagnant,
your body signals this through pain.
You prepare them the day before it starts. Taking them helps for two or three hours, but only temporarily, and as years pass, you feel the same medication is becoming less effective.
Last month it was 25 days, this month 38. Unsure when it will begin, you always plan trips and schedules cautiously.
You often hear that your 'body is cold.' Your abdomen always feels cool to the touch, and on those days, your lower belly feels as heavy as a stone.
The color is dark, and it comes out mixed with clots. The pain is most severe when these clots pass, and you feel a temporary relief afterward.
Ongungbichaek is not a food product.
It is a herbal medicine prescribed by a Korean medicine doctor after consultation.
Fourteen herbs are grouped into three pillars.
We openly disclose which herb belongs to which pillar.
This pillar warms a chilled uterus. When the lower abdomen is cold, blood vessels constrict, hindering blood flow. Stagnant blood then clots, leading to pain. Cinnamomi Ramulus warms and opens the meridians, while Zingiberis Rhizoma disperses internal cold. Both herbs have clinical evidence for menstrual pain.
This pillar works to disperse stagnation. Cnidii Rhizoma, known as the 'Qi herb in blood,' promotes blood circulation. Persicae Semen breaks up stubborn blood stasis, while Moutan Cortex addresses blood stasis accompanied by heat. Angelicae Gigantis Radix replenishes blood, ensuring balance rather than just expulsion.
This pillar manages pain and swelling. Paeoniae Radix eases uterine smooth muscle spasms, while Bupleuri Radix relieves qi stagnation caused by stress. Poria, Atractylodis Rhizoma Alba, and Alismatis Rhizoma help reduce the swelling and heaviness that often worsen during menstruation.
The quickest way to eliminate menstrual pain is to block the pain signals. Indeed, that day passes.
The problem lies in the next month. Blocking signals doesn't address why the pain occurred—whether it's due to cold constriction or stagnant blood that can't exit—so it returns each month with the same intensity on the same day. With prolonged use, you might also feel that the same dosage becomes less effective.
Ongungbichaek changes the conditions that create pain. It warms (Cinnamomi Ramulus · Zingiberis Rhizoma), disperses stagnation (Cnidii Rhizoma · Angelicae Gigantis Radix · Persicae Semen · Moutan Cortex), and in the process, alleviates spasms and swelling (Paeoniae Radix · Bupleuri Radix · Poria · Atractylodis Rhizoma Alba · Alismatis Rhizoma). These fourteen ingredients each address different aspects.
It's not about stopping it once, but about changing the cycle. That's why we consider it on a cycle-by-cycle basis, not just for a single day. It's formulated according to the 'Monarch, Minister, Assistant, Envoy' principle, and it's also why Ongungbichaek discloses all its ingredients.
We verify the functions of the herbal ingredients in Ongungbichaek,
through publicly available research. Each paper also indicates
which aspect of this prescription it supports.

Even for the same symptoms, we do not prescribe the same medicine.

We have not changed our prescriptions to follow trending ingredients. For 11 years, we have maintained the same approach in the same location, and the accumulated responses during this time have shaped our current formulations.
The basis for our decisions—whether to promote blood circulation for a specific constitution, or to prioritize clearing heat over warming in certain cases—comes from real-world experience. Records from over 200,000 cumulative patients serve as the standard for determining prescriptions after consultation.
Beyond Korea, we prescribe to patients in 24 countries, including Japan and the United States. Our experience with patients of varying dietary habits and physiques has broadened our range of intensity adjustments.
We directly operate the Paju External Herbal Preparation Facility designated by the Ministry of Health and Welfare. Since everything from herbal ingredient reception to blending, inspection, and packaging is completed in one place, it is possible to adjust the formulation ratios to suit each patient.
Prescriptions are determined by a Korean medicine doctor after reviewing the consultation details.
Even for the same Ongungbichaek, the intensity and formulation vary for each individual.
Formulated according to the Jun-Sin-Jwa-Sa (君臣佐使) principle.

Ongungbichaek is an herbal medicine prescribed by a Korean medicine doctor after assessing your constitution and condition. Even for the same menstrual pain, the formulation differs significantly depending on whether it's caused by coldness or by accumulated heat. During consultation, the doctor will determine the appropriate strength after checking your cycle, pain patterns, blood color, and presence of clots.
Many patients initially take them together and then gradually reduce painkillers as their pain lessens. However, please inform your Korean medicine doctor about any medications and dosages you are currently taking during your consultation, so they can determine the appropriate timing and combination.
This is not a medication to be taken only on 'that day.' The timing of intake is determined by considering your entire cycle. We choose the approach that best suits your condition, whether it's focusing on use during periods of severe pain or maintaining it throughout the cycle.
We assess progress on a cycle-by-cycle basis. Typically, after two to three cycles, we observe changes in pain intensity, frequency of painkiller use, and the presence of clots, then adjust the dosage accordingly.
While some individuals take them concurrently, the combination with hormone medication must always be assessed by a Korean medicine doctor. Please be sure to inform us of the product name and duration of your current medication during your consultation.
After assessing your cycle, pain patterns, and blood condition via KakaoTalk,
our Korean medicine doctor will guide you on the timing and strength of your dosage.
