Canada balsam is widely used in the preparation of microscope slides due to its excellent optical properties. It acts as a mounting medium, helping to secure specimens between the slide and cover slip while providing clarity and minimal distortion under the microscope. Additionally, it is employed in optics as a cement for lenses, as it has a refractive index similar to that of glass, ensuring seamless bonding and transparency. In art restoration, it is utilized as a varnish or adhesive for repairing and preserving paintings, thanks to its ability to dry clear and remain stable over time. Its versatility also extends to traditional medicine, where it has been used for its soothing and anti-inflammatory properties.
