What is Boiogito (Bōiōgitō)?
Boiogito is a traditional herbal medicine (Kampo) that helps remove excess body fluid (water retention) and regulates perspiration. It is considered suitable for individuals with a pale complexion, a plump physique, who tend to sweat easily, tire easily, and accumulate fluid in their joints (kyo-sho or water retention type). This formula is described in the classic Chinese medical text "Jinkui Yaolue" and has been used in Japan for a long time.
Unusually for a medication used for dieting, "obesity (so-called water retention type with loose muscles)" and swelling are approved indications and effects for this medical Kampo formulation. If it suits your constitution, it can be an easy option to continue.
Recommended for those who:
- Have a pale complexion, more fat than muscle, and a plump physique
- Tend to sweat easily
- Tire easily and experience swelling
- Are concerned about lower body swelling due to standing work, etc.
- Tend to accumulate fluid in their knee joints
- Are hesitant about appetite suppressants or strong medications and wish to improve their constitution from within
Conversely, for those with a sturdy build, good stamina, who are prone to constipation, and accumulate fat around their abdomen, a different Kampo might be more suitable (please refer to the distinction table below).
Component Herbs
Boiogito consists of six types of crude drugs. The daily dose of 7.5g is composed as follows:
| Herb | Quantity | Main Role |
|---|---|---|
| Ougi (Astragalus root) | 5.0g | Regulates body surface fluid balance and suppresses excessive sweating |
| Boi (Stephania root) | 5.0g | Alleviates swelling and joint inflammation through diuretic action |
| Sojutsu (Atractylodes rhizome) | 3.0g | Aids fluid drainage and supports gastrointestinal function |
| Taiso (Jujube fruit) | 3.0g | Soothes the gastrointestinal tract and harmonizes the overall formula |
| Kanzo (Licorice root) | 1.5g | Harmonizes the overall formula. Also a subject of caution for side effects (see below) |
| Shokyo (Ginger rhizome) | 1.0g | Warms the body and aids gastrointestinal function |
*Amounts may vary by product.
Expected Effects and How They Manifest
Boiogito is not a medication that directly reduces body fat. It works by expelling excess fluid, leading to a reduction in swelling and a corresponding change in weight and appearance. Therefore, individuals with severe swelling are more likely to notice changes, while those with fatty obesity may not experience significant changes.
| Period | Guideline |
|---|---|
| 2 weeks to 1 month | Many people begin to notice changes in swelling, ease of sweating, and body sluggishness. |
| 2 to 3 months | Period aimed at constitutional improvement. Continued evaluation. |
| No change after 1 month | Your constitution (sho) may not be suitable. Do not continue blindly; consult us about switching. |
Kampo is a medicine that either works for those it suits or doesn't work for those it doesn't suit. The effects vary from person to person.
Distinction of 3 Types of Diet Kampo
The diet Kampo treatments we offer are distinguished by constitution. Please check which type you are closer to.
| Boiogito | Bofutsushosan | Daishaikoto | |
|---|---|---|---|
| Physical Strength | Weak to normal (water retention type) | Strong (sturdy type) | Strong (sturdy type) |
| Body Type Characteristics | Pale complexion, plump, soft muscles | Fat around abdomen, subcutaneous fat type | Sturdy, epigastric distension |
| Concerning Symptoms | Swelling, sweating easily, fatigue | Constipation, hot flashes | Stress, irritability, stiff shoulders, constipation |
| Main Action | Expels excess fluid | Excretion through sweating, diuresis, and bowel movements | |
| Regulates qi circulation and promotes bowel movements |
Which formula is appropriate will be determined by a doctor based on the medical interview and examination.
Our doctor will select and deliver the appropriate formula for your constitution.
Differences from other diet medications
Kampo's role differs from medications that directly affect appetite or the absorption of sugars and lipids. Because it approaches by correcting constitutional imbalances, its effects are gentle and characterized by minimal burden on the body.
| Type | Mechanism of Action | Recommended for |
|---|---|---|
| Diet Kampo | Regulates constitution, water balance, and bowel movements | Those hesitant about strong medications, prone to swelling, or constipation |
| Metformin | Suppresses glucose production and improves insulin sensitivity | Those who want to continue gradually and affordably for a long time |
| SGLT2 inhibitors | Excretes excess sugar through urine | Those who consume a lot of rice, noodles, and sweets |
| Xenical | Suppresses fat absorption | Those who eat a lot of fried and greasy foods |
| Rybelsus / Mounjaro | Suppresses appetite and maintains satiety | Those who want to suppress appetite itself and lose a significant amount of weight |
Since the mechanisms of action differ, it is sometimes possible to combine Kampo, which regulates the constitution, with other treatments. Please consult us during your examination regarding the possibility of co-administration.
How to take
- Take the daily dose in 2-3 divided doses, before meals or between meals (on an empty stomach).
- The doctor will adjust the dosage according to your constitution and condition.
- If you miss a dose, do not take two doses together; resume the usual schedule from the next dose.
- For swelling countermeasures, combining with lifestyle adjustments such as reducing salt intake and avoiding prolonged sitting or standing will likely yield more noticeable changes.
About side effects
Boiogito contains 1.5g of Glycyrrhiza (licorice root) per daily dose, and long-term, high-dose administration carries a risk of pseudoaldosteronism.
| Symptom | Description and Action |
|---|---|
| Gastric discomfort, loss of appetite | May occur when taken on an empty stomach. If it persists, please consult us. |
| Pseudoaldosteronism | Hypokalemia, elevated blood pressure, swelling, weight gain, numbness or weakness in limbs. If you experience swelling or weight gain despite taking a medication to reduce swelling, this may be a side effect. Discontinue use and consult us. |
| Myopathy | Weakness and muscle pain may occur as a result of hypokalemia. |
| Rash and other allergic reactions (rare) | Discontinue use and seek medical attention. |
Caution with concomitant use of licorice-containing medications
Concomitant use with the following medications increases the risk of pseudoaldosteronism and hypokalemia. Please be sure to inform us during your medical interview about any medications, Kampo, or supplements you are currently taking.
- Kampo medications containing licorice (e.g., Shakuyaku-kanzo-to, Hochu-ekki-to, Yokkan-san, Kakkon-to)
- Preparations containing glycyrrhizin (e.g., liver function improvers, some gastrointestinal medications)
- Diuretics (may further lower serum potassium)
In these cases, we recommend an in-person consultation.
- Individuals receiving treatment for high blood pressure
- Cases where swelling suddenly worsens (may indicate underlying heart, kidney, or thyroid conditions)
- Cases where only one leg suddenly swells, accompanied by pain or warmth (seek medical attention promptly)
- Individuals concerned about interactions with other Kampo medicines or supplements being taken concurrently
- Pregnant or breastfeeding women, or those who may be pregnant
