Se Bok San
Simply reducing intake isn't enough.
Releasing what's accumulated lightens your body.
Is this kind of day
familiar to you?
Constipation is often dismissed as something that passes if you endure it.
However, it quietly erodes your daily condition and body shape.
30 minutes in the morning bathroom
Your morning routine is completely taken up by the bathroom. You sit there scrolling on your phone, only to eventually give up and leave without relief, carrying that discomfort with you all day.
The next day after a company dinner, your lower abdomen remains distended
It feels like last night's meal has been lingering in your belly for three days. Your face and legs are swollen in the morning, and your waist feels tight by evening. The problem wasn't what you ate, but what remained.
It takes days whenever you travel
Your rhythm is disrupted when your bathroom changes. You have no bowel movement for three or four days, only to finally go after returning home. Your stomach is on your mind throughout your otherwise enjoyable trip.
Probiotics · Dietary fiber only help for the first few days
You've tried switching products multiple times, but they only offer 'potential help.' For urgent relief, you resort to over-the-counter laxatives, gradually increasing the dosage.
Se Bok San is not a food product.
It is herbal medicine prepared by a Korean medicine doctor after consultation.

Se Bok San Approaches
from Three Angles
We've grouped six herbs into three pillars.
We clearly state which herb addresses which pillar.
Expulsion · Laxative
This pillar expels accumulated stagnation in the intestines. Rhubarb stimulates the intestinal nerves to restart peristalsis, while mirabilite draws water into the intestines via osmosis, softening hard stools. Though their methods differ, their goal is the same.
Lubrication · Softening
This pillar prepares the passage before expulsion. The fatty oils in peach kernel smooth the intestinal lining, and the mucilage in psyllium husk increases stool volume and water content. It creates a state where passage is possible without forceful pushing.
Circulation · Buffering
This pillar tidies up after expulsion. Cinnamon twig opens circulation in the cold, hardened lower abdomen to prevent lingering heaviness, and licorice root suppresses excessive intestinal contractions, buffering harsh stimulation.
Why not use a single approach?
The fastest way to induce a bowel movement is to use a strong stimulant laxative. It is indeed effective—for the first few days.
The problem arises afterward. Relying on stimulation for expulsion leads to significant side effects like abdominal pain, cramps, and watery diarrhea. Once the stimulation stops, the rhythm returns to its previous state. This is why people become dependent on the medication.
This is why Se Bok San uses six herbs. The stimulant effect (rhubarb) is used minimally, while osmotic (mirabilite), lubricating (peach kernel), and bulking (psyllium husk) effects share the burden. Circulation (cinnamon twig) and buffering (licorice root) then manage the lingering heaviness and irritation.
Instead of using one strongly, six herbs share the load slightly. This is the principle of herbal formulation known as Jun-Shin-Jwa-Sa (君臣佐使) in Korean medicine, and it's why Se Bok San discloses all six ingredients.

Why Jaimdang?
同一诊所积累的临床
We haven't changed our prescriptions to chase trendy ingredients. For 11 years, we've practiced in the same location with the same approach, and the accumulated responses during this time have shaped our current formulations.
Cumulative Consultation Data
We know which constitution experienced excessive strength, and in which cases buffering needed to be increased—our judgments are based on case studies. The records of over 200,000 cumulative patients serve as the basis for determining prescriptions after consultation.
Prescriptions Chosen Across Borders
We prescribe to patients in 24 countries, including Japan and the United States, beyond Korea. Experience treating patients with different dietary habits and body types has broadened our scope for adjusting dosage strength.
In-house manufacturing, not outsourced
We directly operate the Paju External Herbal Preparation Center designated by the Ministry of Health and Welfare. Since everything from ingredient receiving to formulation, inspection, and packaging is completed in one place, we can adjust the formulation ratios to suit individual patients.
Prescriptions are determined by a Korean medicine doctor after reviewing consultation details.
Even for the same Se Bok San, the strength and formulation vary from person to person.

查看全部原料与配方
Rhubarb 大黃
The core of expelling the colon
Clears stagnation in the stomach and intestines through purgation (攻下) and guiding stagnation (導滯), and promotes bowel movement by activating blood and resolving stasis (活血祛瘀).
Anthraquinone-class sennosides are metabolized into rheinanthrone in the colon, stimulating the intestinal nerve plexus and increasing peristalsis and water secretion, thus exerting a purgative effect.
Mirabilite 芒硝
Softens hard stools
With its salty and cold properties, it softens hardened and dry stools (軟堅潤燥) and clears accumulated heat (積熱).
Sodium sulfate creates osmotic pressure in the intestinal lumen, drawing in water to soften and increase the volume of stool, thereby promoting defecation.
Peach Kernel 桃仁
Activates blood · Lubricates intestines
Promotes bowel movement by activating blood and resolving stasis (活血祛瘀) and lubricating the intestines (潤腸通便), addressing both blood stasis in the lower abdomen and constipation.
Abundant fatty oils and amygdalin lubricate the intestinal mucosa and improve local blood flow, facilitating smooth bowel transit.
Psyllium Husk 車前子皮
Expels waste with fiber
With its sweet and cold properties, it promotes urination and clears dampness (利水通淋) and heat (清熱), lubricating the intestines to ensure smooth passage.
Water-soluble mucilage absorbs water, increasing stool volume and water retention (bulking laxative effect), and also acts as a prebiotic by serving as a substrate for intestinal fermentation.
Cinnamon Twig 桂枝
Warms yang · Promotes circulation
Warms the meridians (溫通經脈) and disperses cold pathogens (散寒解肌), dispelling coldness and promoting the flow of yang energy.
Cinnamaldehyde induces nitric oxide (NO) production in vascular endothelium, improving microcirculation and aiding in the recovery of intestinal function.
Licorice Root 甘草
Harmonizes · Relieves spasms
Harmonizes the properties of various herbs (調和諸藥) and relieves acute spasms and pain (緩急止痛).
Glycyrrhizin and glycyrrhetinic acid relax excessive smooth muscle contractions and protect the mucosa, buffering irritation.
The combination ratio is adjusted according to the prescription stage, and the final composition is determined after consultation with a Korean medicine doctor.

Se Bok San is herbal medicine prepared by a Korean medicine doctor after assessing your constitution and condition. Bowel response varies by individual, so we adjust the strength based on consultation details. If long-term use is necessary, be sure to consult with your Korean medicine doctor.
FAQ
How is it different from over-the-counter laxatives?
Instead of expelling with a single ingredient, our goal is to promote smooth passage by combining expulsion (rhubarb, mirabilite), intestinal lubrication (peach kernel, psyllium husk), and circulation (cinnamon twig). This is also why licorice root is used to buffer irritation.
Do I have to take it continuously?
No. Once your bowel rhythm is established, we reduce the strength or discontinue use and transition to maintenance management. Your Korean medicine doctor will guide you on when to do this.
How much weight will I lose?
Se Bok San is a prescription designed to release accumulated waste rather than for weight loss itself. We do not promise specific numbers; instead, we set realistic goals together during the consultation.
Can I take it with other prescriptions?
It is often used concurrently with prescriptions like Gongbi-hwan, but the combination and dosage must be determined by a Korean medicine doctor. Do not take them together arbitrarily.
I've been taking over-the-counter laxatives for a long time, is that okay?
We often see patients who have used stimulant laxatives for extended periods. In such cases, we start by increasing the proportion of intestinal lubricants (peach kernel, psyllium husk) and osmotic agents (mirabilite), rather than using strong rhubarb from the outset, to reduce dependency on stimulation. Please inform us during your consultation about the medications you've taken and for how long.
