Birchbark is used to make birch-tar, a particularly fine tar. The terms tar and pitch are often used interchangeably. However, pitch is considered more solid, while tar is more liquid. Traditionally, pitch that was used for waterproofing buckets, barrels and ships was drawn from pine. It is used to make cutler's resin.
The Ojibwe also used pine resin to successfully treat infections and even gangrenous wounds, [39] because pine resin apparently has a number of quite efficient antimicrobials. Generally, a wet pulp from the inner bark, or pine tar mixed with beeswax or butter was applied to wounds and used as a salve to prevent infection.
