Geodorum densiflorum otherwise known as Nodding Swamp Orchid is a perennial orchid commonly found in East Asia. Its shoots are about 20-30cm long. It has pseudobulbs that are usually about 13-26mm n diameter. The leaves are oval in shape and are pleated along their length. The flowering stalk has 8-10 pink flowers. In Australia, it has been considered as an endangered species due to urbanization. The tuberous base is used to moisturize body parts and to relieve soreness. It also yields a glue-like substance with great tenacity used for cementing parts of musical instruments.

Other Uses

Adhesive  Cosmetic  Gum

Other Uses: A glue-like substance is obtained from the tuberous roots[46 ]. A very strong glue with great tenacity[46 ]. 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 ]. The water extraction of the plant gives a gum which is separated by precipitation with alcohol. This gum has exceptional strength and lasting power[579 ].
