sticky, resinous secretion of the tiny lac insect, Laccifer lacca, which is a species of scale insect. This insect deposits lac on the twigs and young branches of several varieties of soapberry and acacia trees and particularly on the sacred fig, Ficus religiosa, in India, Thailand, Myanmar (Burma), and elsewhere in Southeast Asia.
