See Plants. The Hebrew term chelbanah of Exodus 30:34 has been viewed by some scholars as a reference to the galbanum gum. Other scholars dispute this and suggest instead that it is a reference to the gum of the storax tree. The term appears in the text which lists the types of plant derived-materials from which the congregation was to produce a sacred incense for the Holy Tabernacle.
The Galbanum looks like wild parsley and it is used to produce a pungent waxy resinous gum.
