When considering diet methods, the question "Would Korean medicine or Western medicine be better?" often comes up. To answer directly: Korean medicine works through increasing basal metabolic rate and improving constitution, while Western medicine works through central nervous system appetite suppression—they work differently. Rather than one being inherently better, the suitable approach varies depending on individual constitution and health status, so understanding the exact differences between the two is important first.
What is the core difference between diet Korean medicine and Western medicine?
Diet Korean medicine and Western medicine are fundamentally different in 'through what pathway weight is lost.'
Korean medicine approaches by increasing basal metabolic rate and enhancing satiety through changes in the autonomic nervous system and hormones. Simply put, it's a method of adjusting the constitution itself so the body can use energy more effectively. Health information from Hidoc also introduces diet Korean medicine as utilizing autonomic nervous system and metabolic regulation pathways.
In contrast, Western medicine (phentermine class) acts on the central nervous system to regulate dopamine and serotonin secretion, thereby suppressing appetite itself. According to health information from Soonchunhyang University Gumi Hospital, phentermine is classified as a psychoactive medication with concerns about addiction and withdrawal symptoms, so it must be taken under prescription from a specialist.
Both require prescription from a doctor or Korean medicine doctor, and the suitable choice varies depending on constitution and current health status. Rather than unconditionally choosing one side, it's important to first assess your own situation.
Mini Q&A
Q. Does diet Korean medicine also require a prescription?
Yes, Korean medicine is also prescribed individually by a Korean medicine doctor after confirming constitution and health status. The principle is not to prescribe even identical ingredients if they don't match your constitution.
Ingredients and mechanisms of action — Ephedra (ephedrine) vs. phentermine and GLP-1
The differences become clearer when comparing ingredients and mechanisms of action side by side.
| Category | Main ingredients | Mechanism of action | Main precautions |
|---|---|---|---|
| Diet Korean medicine | Ephedra (ephedrine) | Stimulate sympathetic nervous system → promote thermogenesis → body fat decomposition | Caution for those with cardiovascular disease or hypertension |
| Western medicine (appetite suppressant) | Phentermine | Central nervous system stimulation → dopamine and serotonin regulation → appetite suppression | Psychoactive medication, concerns about dependence and withdrawal |
| Western medicine (fat absorption inhibitor) | Orlistat | Digestive enzyme (lipase) inhibition → block fat absorption | Possible decreased absorption of fat-soluble vitamins |
| Western medicine (GLP-1 class) | Semaglutide, etc. | Mimic intestinal hormone → slow gastric emptying → increase satiety | Injectable form, gastrointestinal side effects such as nausea and vomiting |
Ephedrine, the main component of ephedra, is classified as a thermogenesis promoter that stimulates the sympathetic nervous system and increases 24-hour energy expenditure. According to clinical data, a group taking ephedrine-containing preparations for 90 days showed an average body weight reduction of 5.3kg and 16.1% body fat reduction (academic paper from Ewha Womans University DBpia). However, this is an average result, and results may vary depending on individual circumstances.
GLP-1 class medications, as introduced in health information from the National Medical Center, work by mimicking intestinal hormones to slow gastric emptying and increase satiety. Although recently receiving attention, they are in injectable form and may have gastrointestinal side effects, so specialist consultation must be done beforehand.
According to drug materials from the Health Insurance Review and Assessment Service, phentermine has an amphetamine-like structure with concerns about rebound weight gain and dependence upon discontinuation. Since the side effect profile differs by ingredient, we strongly recommend consulting with a specialist before taking these medications.
How is mail100yr kmd daily weight-loss pills different?
Dr. Won-seok Song from mail100yr kmd, who began research directly for his wife whose weight did not return after childbirth, has prescribed and improved the daily weight-loss pills for over 10 years. The daily weight-loss pills are designed so that if uncomfortable reactions such as headaches or nausea occur, you can immediately lower the dosage level and take them safely by adjusting the number of pills from 1-8 stages.
The prescription principles of daily weight-loss pills can be summarized as follows:
✓ Transparent disclosure of ephedra (ephedrine) ingredients — The fact that ingredients are contained is clarified from the start, and the principle is not to prescribe if they don't match your constitution.
✓ Fine adjustment prescription from 1-8 stages — If uncomfortable reactions such as headaches, nausea, or insomnia appear, the number of pills can be immediately reduced to minimize side effects.
✓ Accumulated prescription data of over 70,000 cases — Continuously improved based on over 10 years of prescription experience.
✓ Liver safety data available — Based on 17,089 prescribed cases, abnormal liver function was confirmed to occur in less than 0.3%. BMJ (2015) research also confirmed that hepatotoxicity from ephedra-containing Korean medicine is at a similar level to general medications.
✓ Designed for body fat-focused reduction — Focuses on reducing body fat without muscle loss through increased basal metabolic rate. Based on in-person visits, the body fat-focused reduction rate is 89.9%.
✓ Operates rebound management packages — Provides up to 6 months of rebound management options for maintenance after weight loss.
The Journal of Health and Medical Science 12(1), 2024 review of safety in obesity treatment using ephedra and ephedrine also confirms safety when used within appropriate doses. The daily weight-loss pills manage side effect risks through personal customized stage adjustment based on this evidence.
These people need to be careful
Both diet Korean medicine and Western medicine require first confirming 'whether it matches my body.' If any of the items below apply to you, please consult with a specialist before taking them.
✓ People with cardiovascular disease or hypertension — According to health information from Kormedi, if the ephedrine ingredient acts excessively, cardiovascular side effects such as blood pressure elevation and increased heart rate may occur. This applies to both Korean and Western medicine.
✓ People with thyroid disease — If you have a metabolism-related condition, interactions may occur in the process of adjusting basal metabolic rate, requiring special caution.
✓ People currently taking Western medicine appetite suppressants — According to the Korean Association of Oriental Medicine for Obesity, concurrent use of ephedra-containing Korean medicine and Western medicine appetite suppressants is listed as a contraindication. Be sure to inform your prescribing doctor or Korean medicine doctor of your current medications first.
✓ Pregnant women and nursing mothers — Due to ingredient characteristics, intake is not recommended, and even if postpartum diet is needed, prescription after weaning is recommended.
✓ People who experienced severe palpitations or insomnia after taking ephedra ingredients — If you have previously experienced uncomfortable reactions to similar ingredients, determine constitutional suitability first before deciding on prescription.

If in-person visits are difficult, nationwide delivery receipt is available.
If you're curious about what direction suits you, confirm through consultation.
If you're curious about what direction suits you, check your constitution and current health status first through mail100yr kmd's non-face-to-face consultation — nationwide delivery receipt is possible all at once.
Whether Korean medicine or Western medicine is more suitable cannot be determined by looking only at current weight and body shape, but must be based on a comprehensive assessment including basal metabolic rate status, lifestyle patterns, medications being taken, and presence of underlying diseases. Finding 'the method that suits my body' rather than simply 'the method that loses the most weight' is the key to maintaining results without rebound.
Related medical information emphasizes that preventing rebound requires identifying obesity causes by constitution and using personalized metabolic activation approaches. The 72% re-prescription rate and 89.9% body fat-focused reduction rate of daily weight-loss pills reflect results designed with post-weight-loss maintenance management included.
If you're hesitant about starting, there's also an option to first check how your body responds with a 1-month short-term option (110,000 won). If you're very concerned about rebound after weight loss, you can manage systematically through a 2-3 month weight loss + 6-month rebound management package.
Results may vary depending on individual circumstances. We recommend first consulting to confirm the prescription direction that matches your constitution.
You're curious about these things
Q1. Can I take diet Korean medicine and Western medicine together?
Concurrent use is not recommended. Both ephedra (ephedrine) and Western medicine appetite suppressants act on the sympathetic or central nervous system, so combined use may result in overlapping side effects such as blood pressure elevation and increased heart rate. If you're currently taking Western medicine, be sure to inform your prescribing doctor or Korean medicine doctor first.
Q2. Is herbal medicine containing ephedra (ephedrine) really safe for the liver?
Based on 17,089 prescribed cases, abnormal liver function was confirmed to occur in less than 0.3%, and BMJ (2015) research also confirmed that hepatotoxicity from ephedra-containing Korean medicine is at a similar level to general medications. However, if you have existing liver disease or are taking other medications, consultation before use is needed, and results may vary depending on individual circumstances.
Q3. After stopping Western medicine appetite suppressants, I experience severe rebound. Can I manage it with herbal medicine?
Western medicine appetite suppressants often have rapidly returning appetite after discontinuation. Herbal medicine aims for increased basal metabolic rate and constitutional improvement, so it approaches maintaining metabolic status even after stopping medication. Daily weight-loss pills operates a maximum 6-month rebound management package after weight loss, allowing you to manage systematically through the maintenance period. However, since prescription is decided after constitutional confirmation, we recommend first consulting.
