Herbal Decoction

Learn about the efficacy, usage, side effects, and precautions of herbal decoctions. This is a form of Korean herbal medicine prepared as a liquid by boiling medicinal herbs in water; packaging, storage, and dosage must follow the actual dispensing instructions. Even if the pouches look similar, the moisture content, packaging, and dispensing date may differ. Prioritize the dosage and storage conditions written on the actual dispensing label over general information found on the internet. If a pouch is leaking, swollen, or if the smell and color have changed from usual, do not taste it to check the condition. Inform the dispensing institution of the remaining decoction and storage history to confirm whether it is safe to consume.
