The characteristics of rhizomes are recognized by traders through their size, color, and aroma. The cross-section of the rhizomes of each species is different in structure and color which is used as the main marker for each species. Rhizoma Zingiberaceae is used as the main ingredient for tawar (semi-solid medicinal herbs consumed by brewing), parem (solid medicinal ingredients), and oukup (traditional Karo sauna). The rhizome aroma of each species belonging Zingiberaceae is very distinctive which is related to the content of essential oils. The use of Zingiberaceae rhizomes as tawar and parem ingredients needs to be studied further so that they are developed into standardized herbs.
