What is Bofutsushosan?

Bofutsushosan is a herbal medicine that has both a laxative effect to improve bowel movements and a function to expel excess heat and waste products through sweating and diuresis. It is said to be suitable for people with a "sturdy build" who have strong physical strength and tend to accumulate fat around their abdomen.

The approved indications and effects are "various symptoms in people with a lot of subcutaneous fat in the abdomen and a tendency to constipation: accompanying symptoms of high blood pressure (palpitations, stiff shoulders, hot flashes), obesity, swelling, and constipation." It is a rare medical herbal preparation among weight loss drugs that officially includes obesity as an indication.

Recommended for people who:

  • Have relatively strong physical strength and a sturdy build
  • Tend to be constipated
  • Are concerned about fat around their abdomen
  • Sometimes experience stiff shoulders or hot flashes

Not suitable for people who:

  • Have low physical strength or are thin
  • Have a weak stomach and are prone to diarrhea
  • Are elderly (as sweating and laxative effects can deplete physical strength)
  • Have high blood pressure, heart disease, hyperthyroidism, prostatic hypertrophy, etc. (see the section on Ephedra below)
  • Are pregnant or breastfeeding

18 crude drugs and 4 functions

Bofutsushosan is composed of 18 types of crude drugs and is designed to expel excess substances accumulated in the body through four routes.

Function Main Crude Drugs Content
Diaphoresis Ephedra, Schizonepeta, Ledebouriella Expels excess heat through sweat
Purgation (bowel movements) Rhubarb, Mirabilite Stimulates the intestines and expels waste as stool
Diuresis Talc, Atractylodes Rhizome Expels water and waste products as urine
Clearing heat Gypsum, Scutellaria, Gardenia, Forsythia Cools down heat accumulated in the body

The daily dose of 7.5g includes talc 3.0g, scutellaria 2.0g, licorice 2.0g, platycodon 2.0g, gypsum 2.0g, atractylodes rhizome 2.0g, rhubarb 1.5g, schizonepeta 1.2g, gardenia 1.2g, etc. (varies by product). Since it contains licorice, rhubarb, ephedra, and gardenia, the precautions described later are important.

Expected effects and how they manifest

Bofutsushosan is not a "fat-burning drug that works simply by taking it." It is a medicine that leads to results by expelling excess substances through bowel movements, sweating, and diuresis, and by adjusting the body's imbalances. It is more effective when combined with a review of diet and exercise.

Period Guideline
A few days to 1 week Many people feel a change in bowel movements
2-3 months Period to evaluate changes in abdominal fat and body constitution
No change after 1 month of continued use Your body constitution (sho) may not be suitable. Do not continue aimlessly; please consult us about switching.

Kanpo (traditional Japanese herbal medicine) has a clear characteristic: "it works for those it suits, and it doesn't work for those it doesn't." Individual results may vary.

Differences from other diet medications

Type Mechanism of action Suitable for
Diet Kanpo Regulates body constitution, bowel movements, and water balance Those who are reluctant to take strong medication, tend to be constipated, or are prone to swelling
Metformin Suppresses glucose production and improves insulin sensitivity Those who want to continue gradually and affordably for a long time
SGLT2 inhibitors Expels excess sugar as urine Those who eat a lot of rice, noodles, or sweets
Xenical Suppresses fat absorption Those who eat a lot of fried or fatty foods
Rybelsus / Mounjaro Suppresses appetite and maintains satiety Those who want to suppress appetite itself or lose a significant amount of weight

Since the mechanisms of action differ, we may combine Kanpo, which regulates body constitution, with other treatments. Please consult us during your examination about the possibility of concurrent use.

How to take

  • Take the daily dose divided into 2-3 times, before meals or between meals (on an empty stomach).
  • The doctor will adjust the dosage according to your constitution and condition. If your stools become too loose, the dosage can be adjusted by reducing it.
  • If you miss a dose, do not take two doses at once; return to your usual schedule from the next dose.
  • Since it has diaphoretic and diuretic effects, please drink water frequently.

Side effects and precautions

Main side effects

Symptom Description and Management
Diarrhea, soft stools, abdominal pain Caused by the purgative effect of rhubarb. The intensity of the effect varies among individuals. If the effect is too strong, the dosage can be adjusted by reducing it, so please consult us instead of discontinuing on your own.
Loss of appetite, stomach discomfort, nausea These symptoms are common in people with sensitive stomachs. If they persist, please consult us.
Palpitations, tachycardia, insomnia, excessive sweating, mental excitation Caused by the sympathomimetic effect of Ephedra (see below)
Urinary dysfunction Effect of Ephedra. Special caution is needed for those with prostatic hypertrophy.
Pseudoaldosteronism, myopathy Caused by licorice. Low potassium levels, increased blood pressure, swelling, weight gain, numbness and weakness in limbs. If these appear, stop taking the medicine and consult us.
Rash, itching (rare) Stop taking and seek medical attention.

Precautions due to containing Ephedra (Maō)

Bofutsushosan contains Ephedra (Maō). Ephedra contains ephedrine-like substances and stimulates the sympathetic nervous system, which can increase the likelihood of insomnia, excessive sweating, tachycardia, palpitations, general weakness, and mental excitation when combined with the following medications or products:

  • Other Kanpo medicines containing Ephedra (e.g., Kakkonto, Shoseiryuto, Maoto)
  • Ephedrine-like substances found in over-the-counter cold and nasal medicines (e.g., pseudoephedrine, dl-methylephedrine)
  • MAO inhibitors, thyroid hormone preparations, catecholamine preparations, xanthine derivatives such as theophylline

Overlapping with over-the-counter medications can be difficult to notice on your own. Please be sure to inform us of any over-the-counter medications or supplements you are currently taking during your consultation.

Precautions for long-term use (Mesenteric Venosclerosis)

Gardenia (Sanshishi), contained in Bofutsushosan, is known to cause mesenteric venosclerosis, which involves abnormal colon color, edema, erosions, ulcers, and strictures, with long-term use (often 5 years or more). Cases requiring intestinal resection have also been reported.

  • If you experience recurring abdominal pain, diarrhea, constipation, or abdominal distension, stop taking the medicine and consult us.
  • Please also consult us if your stool occult blood test is positive during a health checkup.
  • For those continuing long-term, we recommend regular CT scans and colonoscopies.

Serious side effects

Although rare, if any of the following symptoms appear, discontinue use and seek medical attention promptly:

  • Interstitial pneumonia: cough, shortness of breath/difficulty breathing, fever
  • Liver dysfunction/jaundice: severe fatigue, loss of appetite, yellowing of whites of eyes or skin, dark urine

Concomitant use with other Kanpo medicines and drugs

  • When combining with other Kanpo preparations, please be careful about overlapping crude drugs. In particular, concomitant use with preparations containing rhubarb may result in excessively strong laxative effects.
  • Concomitant use with Kanpo medicines containing licorice (e.g., Shakuyakukanzoto, Hochuekkito, Yokukansan) or preparations containing glycyrrhizinic acid increases the risk of pseudoaldosteronism.
  • Since this product contains sodium sulfate, caution is required for continued use by those who need to restrict dietary salt for medical treatment.
  • For breastfeeding mothers, components of rhubarb may transfer to breast milk and cause diarrhea in the infant.

We recommend in-person consultation in the following cases:

  • Patients being treated for high blood pressure or heart disease
  • Patients with thyroid disease or prostatic hypertrophy
  • If symptoms such as swelling, palpitations, or severe weakness occur
  • If abdominal pain, diarrhea, constipation, or abdominal distension occurs repeatedly
  • Patients who are taking other herbal medicines, over-the-counter drugs, or supplements and are concerned about drug interactions

Frequently Asked Questions

Q. How long does it take for Bofutsushosan to take effect?
A. Many people experience changes in bowel movements within a few days to a week, and for changes around the abdomen, it typically takes 2-3 months of continuous use. If there is no change at all after about one month, it may indicate that your body constitution (sho) is not suitable, so please consult us instead of continuing aimlessly. Individual results may vary.
Q. Is it a medicine that burns fat and helps you lose weight?
A. It is not a "fat-burning pill that you just take." It is a medicine that helps with weight and abdominal changes by expelling excess waste through bowel movements, sweating, and urination, and by balancing bodily constitution. You are more likely to see results when combined with a review of your diet and exercise.
Q. Can I take it with over-the-counter cold medicines or rhinitis medicines?
A. Caution is required. Bofutsushosan contains ephedra, and if taken with ephedrine-like substances found in over-the-counter cold medicines and rhinitis medicines, it can easily lead to palpitations, insomnia, excessive sweating, and mental excitement. The same applies to other Kampo medicines containing ephedra, such as Kakkonto. Please be sure to inform us of any over-the-counter medications you are currently taking.
Q. I'm experiencing diarrhea. What should I do?
A. Bofutsushosan contains rhubarb, and the effectiveness of its laxative action varies from person to person. If it is too effective, it can often be improved by adjusting the dosage, so please consult us instead of stopping on your own. It is not suitable for those who are prone to diarrhea or have a weak gastrointestinal system.
Q. Is it safe to take for a long time?
A. There are precautions when continuing long-term. It is known that long-term use (often 5 years or more) of gardenia, which is included, may cause a bowel disease called mesenteric venosclerosis. If you experience repeated abdominal pain, diarrhea, constipation, or abdominal bloating, stop taking it and consult us. We recommend regular check-ups for those who continue long-term. Also, caution is required for pseudoaldosteronism due to licorice.
