Camphor oil is also used in various topical products for its potential analgesic and anti-inflammatory properties.

2. Religious and spiritual practices: Camphor holds religious significance in some traditions, particularly in Hindu rituals. It is used as an offering and is burned during prayers and ceremonies. The smoke from burning camphor is believed to purify the surroundings and create a pleasant atmosphere.

3. Insect repellent: Camphor is known for its insect-repelling properties. It is often used in the form of tablets or balls placed in wardrobes or drawers to deter moths and other insects. It can also be used to repel mosquitoes when used in the appropriate manner.
