Based on reports from those who have taken diet herbal medicine, experiences generally fall into two categories. One group feels their metabolism revive and body become lighter—in Traditional Korean Medicine, this is viewed as the expulsion of phlegm-fluid (痰飮, dameum), meaning accumulated metabolic waste. As excess moisture and toxins are eliminated, swelling decreases and the body feels noticeably lighter. The other group requires an initial adaptation period. Individuals with qi deficiency and spleen deficiency (脾虛, biheo)—weakened spleen function and poor digestion—may experience heart palpitations or insomnia even with a mildly strong prescription. I recall in my early years as a Korean medicine doctor, I was overzealous and ignored my own body's signals, taking a prescription that left me struggling for days—a real lesson. Those with blood stasis (瘀血, eohyeol)—blocked circulation—may initially feel heavier before suddenly experiencing a release. Ultimately, the key is carefully monitoring your body's responses. Starting with a strong prescription is not optimal; a stepwise adjustment based on your current condition reduces risks of yo-yo effects or side effects.
