Preparation Date

The date the Korean herbal medicine was prepared at the Korean medicine clinic; this is different from the expiration date or the date of opening. Do not discard it immediately simply because the preparation date was a long time ago, nor resume taking it simply because it looks fine. If the expiration date and storage instructions cannot be confirmed, withhold consumption and consult on whether a new prescription is needed. If you have received multiple preparations, keep each package separated by date. Also, separately record the date of receipt and the date it was first opened.
