Diet herbal medicine is not a one-size-fits-all approach—the dosage timing and method vary according to your constitution and current condition. I emphasize this because I initially struggled myself without understanding the constitutional aspect. First, a Korean medicine clinic will identify key mechanisms such as Pi deficiency (脾虛), Phlegm-fluid (痰飮), or Blood stasis (瘀血) through constitution assessment and pulse diagnosis. The combination of these three determines the core of the administration method. - **Pi deficiency (脾虛) dominant**: The spleen function is weak, leading to poor digestion and easy bloating. Herbs that act like digestive enzymes are included. Take them with lukewarm water 30 minutes to 1 hour after meals. Taking them before meals may burden the stomach. - **Phlegm-fluid (痰飮) tendency**: Excess moisture and waste accumulate in the body. Take the medicine about 30 minutes before meals to boost metabolism. If the formula contains warming herbs like cinnamon (肉桂) or atractylodes (蒼朮), drink it warm. - **Blood stasis (瘀血) issue**: Poor blood circulation with localized stagnation. Usually, take it on an empty stomach in the morning. Herbs like peach kernel (桃仁) or safflower (紅花) improve blood flow, but taking them in the evening may disturb sleep. Mixed conditions are common, and dosage or frequency may be adjusted based on individual reactions. For example, those with a cold constitution might reduce from three times to two times daily, or if the formula contains many hot-natured herbs, dissolve it in warm water rather than cold. Ultimately, the correct answer is 'follow the prescription given after consultation,' but understanding these principles can ease any anxiety. Feel free to ask during your visit—I too found that diet herbal medicine is far more effective when approached systematically with a professional rather than alone.
