Also: Canada turpentine,Balsam of fir,is a turpentine which is made from the resin of the balsam fir tree (Abies balsamea)
For Cestodes specially,for making permanent slides,at the final stage ,after dehydration,the stained worm is placed on the canada balsam, and then the coverslip is placed on them
For Digenes, Schistosomes, used for mounting the worms on slides
The disadvantage of Canada balsam is, that the specimen must be placed into Xylene (that is toxic) before embedding. Wet specimens must first be dehydrated in alcohol and then transferred to xylene. Transferring specimens directly from alcohol to Canada balsam won’t work, because the alcohol won’t dissolve the Canada balsam.
