Peru-balsam tincture.—Peru balsam 8 ozs., best quality of alcohol 5 quarts.
Tolu-balsam tincture.—Tolu balsam 3 lbs., best quality of alcohol 5 quarts.
Bring the alcohol into a bottle. Tolu balsam cannot be reduced to a powder, hence it is necessary to keep it right cool, whereby it becomes brittle so that it can be cut up with a sharp instrument and a hammer. The pieces detached are rapidly brought into the alcohol, solution taking place in about 14 days. If the alcohol were added to the tolu balsam, the latter would ball together, rendering solution very difficult. Frequent vigorous shaking is necessary.
Olibanum tincture.—Olibanum 2 lbs., best quality of alcohol 4 quarts.
Reduce the olibanum to as fine a powder as possible, bring it into a flask, add the alcohol and shake frequently.
Opopanax tincture.—Opopanax 2 lbs., best quality of alcohol 4 quarts.
Reduce the opopanax to a coarse powder, bring it into a bottle, add the alcohol and shake frequently.
Storax tincture.—Storax liquidus 4 lbs., alcohol of best quality 5 quarts.
Bring the alcohol first into the flask. Then place the pot containing the storax in warm water until it becomes more liquid, and then pour it in very thin threads into the flask. Shake frequently.
Myrrh tincture.—Myrrh 1 lb., best quality of alcohol 2 quarts.
