What is herbal diet medicine? Principles, effects, side effects, and how to take it: a complete guide

Herbal diet medicine is not a medicine that makes you 'eat less'; it is a prescription that returns the body to a 'state where weight comes off easily.' Korean medicine views obesity as the result of broken metabolic function and balance. So herbal diet medicine works through three principles together.
The 3 principles of herbal diet medicine
1. Boosting metabolism
A body with a low basal metabolic rate is like a car with poor fuel economy: even a little food leaves leftover energy that piles up as fat. Herbal diet medicine wakes up the mitochondria, the cells' energy factories, to increase heat production and energy use. The energy you use even at rest goes up.
2. Regulating appetite
Much of the hard-to-resist appetite is 'false hunger' caused by stress (liver qi stagnation) or heat built up in the stomach (stomach heat). Instead of suppressing the brain, herbal medicine addresses these causes and helps restore a normal sense of fullness, so you feel satisfied eating a moderate amount.
3. Clearing the body's waste
Dampness-phlegm (濕痰) and blood stasis (瘀血), waste stagnating in the body, get in the way of metabolism. Herbal medicine smooths qi-blood circulation, urination, and bowel movements to clear swelling and waste and make the body feel lighter.
Main herbs
| Herbs | Main role |
|---|---|
| Ephedra (麻黃, mahuang) | Activates the sympathetic nervous system; boosts heat production and metabolism; regulates appetite |
| Hawthorn (山査) | Breaks down fat; aids digestion |
| Astragalus (黃芪) | Strengthens energy and immunity |
| Atractylodes (白朮) · Poria (茯苓) · Coix seed (薏苡仁) | Water metabolism; eases swelling; strengthens digestive function |
| Rehmannia root · Goji berry | Replenishes energy; blood sugar and hormone balance |
| Gongjindan (musk, deer antler, cornus fruit, angelica root) | Replenishes the qi, blood, and stamina that drop during weight loss (GONG BI JIN YAK) |
The actual prescription is adjusted by constitution and stage. You can see the herbs for each Miple prescription on the MYCUT and GONG BI JIN YAK pages.
Side effects and precautions
During the early adjustment period, you may notice nausea, palpitations, hand tremor, headache, or poor sleep. Your body is responding to the urgent situation of burning body fat, a kind of good stress, and it does not mean the medicine is wrong for you. Most people feel better within a few days to 1-2 weeks. Drink plenty of water and do not cut salt too much. Only in rare cases such as chest pain or shortness of breath should you stop taking the medicine and contact us. At Miple Korean Medicine Clinic, no serious side effects related to the liver, kidneys, or hormones have been reported over 15 years of prescribing to more than 20,000 people and in more than 100,000 prescriptions.
When you must take it only after a consultation
- If you are pregnant or breastfeeding
- If you have high blood pressure, heart disease, or a thyroid condition
- If you take other medication (especially GLP-1 injections, diabetes medicine, or psychiatric medication)
How to take it

Frequently Asked Questions
Does herbal diet medicine work?
Herbal diet medicine supports weight loss through the principles of boosting metabolism, regulating appetite, and clearing waste. Effects vary from person to person with constitution and lifestyle, and testing before prescribing and stage adjustment shape the result.
Does the weight come back if I stop herbal diet medicine?
If you stop right after weight loss, appetite returns while metabolism is lowered, so the yo-yo effect is easy to occur. A soft landing of 3 to 6 months or more with a maintenance-stage prescription at a lower stage helps the new weight settle in.
How is herbal diet medicine different from Wegovy and Mounjaro?
Wegovy and Mounjaro are injections that mimic satiety hormones to suppress appetite, while herbal diet medicine activates metabolism so the body uses energy on its own. You can see a detailed comparison in the health column 'Wegovy and Mounjaro vs herbal diet medicine.'
Curious about a prescription that fits your body?
After a body composition test, the head doctor consults with you in person.
