"Herbal medicine" can mean anything from supermarket teas to serious clinical prescriptions. In Korea, bo-yak belongs firmly to the second category.

Prescribed by a doctor, not picked off a shelf
A bo-yak prescription begins with a medical consultation: pulse and tongue examination, health history, current medications. The doctor then composes a formula — typically 10-20 herbs in individualized ratios — for your specific pattern. Two people with "fatigue" rarely receive the same formula.
How quality and safety are managed
Medicinal herbs in Korea are regulated separately from food-grade herbs, with testing for heavy metals, pesticides, and origin. At LIMDA, prescriptions are decocted at a licensed external herbal dispensary, prepared one patient at a time. Prescriptions are issued in 15-day units, so the doctor reviews how your body responds before continuing — nothing is sold in bulk.
What bo-yak is used for
Recovery from fatigue and burnout, postpartum recovery, sleep quality, digestion, seasonal immunity, menopausal transition, and general resilience — situations where several small imbalances add up.
Taking it as an international patient
Formulas come as ready-to-drink pouches that keep at room temperature and travel well. Instructions are provided in English, and your medication list is checked for interactions before prescribing.
Q. Is it safe with Western medication? A. Usually yes, with timing separation — but always share your full medication list first.
Q. Does it taste terrible? A. Modern formulas are milder than the stereotype, and LIMDA offers lighter daily-style options as well. Q. Can I take it home overseas? A. Pouches are sealed and travel-friendly; we provide documentation for customs if needed. Q. How soon does it work? A. Most people review changes with the doctor after the first 15-day cycle.
