It is used for cementing parts of musical instruments such as guitars and mandolins[46 , 345 ]. The glue is prepared in different ways. The simplest method is to simply split the rhizomes and then rub the pulp on the surfaces to be glued[579 ]. Alternatively, when the rhizomes are first cooked and then finely grated, they are said to have great tenacity[345 , 579 ].
