Camphor is a white crystalline substance, obtained from the tree Cinnamonum camphora, the Camphor Laurel, much valued for its medicinal value. A common ingredient in a wide variety of over-the-counter topical products today, Camphor has been traditionally used topically to relieve pain, and treat warts, cold sores, hemorrhoids and osteoarthritis.

The Camphor tree is a large evergreen tree that grows in Eastern Asia, Northern Africa, Argentina, Brazil, Egypt, Madagascar, southern Europe, and even in the US. It often grows to more than 100 feet in height, yields red leaves that turn dark green with age; small, pale-colored flowers and crimson berries. Camphor tree flowers yield nectar to produce honey.

Why should I be aware about it?

Camphor is an easy to source herb in Asia, Europe and the US, and is used extensively in alternative herbal treatments. It treats problems such as muscle pain, strains, rheumatism and chapped hands. As camphor is a counter-irritant and its oil helps in numbing the peripheral sensory nerves, camphor oil was traditionally massaged into sprains and sore muscles and joints for pain relief. It is particularly effective in the treatment for arthritic and rheumatic joint pain.

When camphor is burnt it purifies the atmosphere and acts as an excellent germ killer and a natural mosquito repellent.

Because of its natural preservative and insect repellant properties, camphor wood was used to make many traveling and storage trunks and cabinets in which contents could be preserved. In the old days, camphor wood was used in the manufacture of sailor’s chests as it is resistant to salty air and water corrosion. During the 1800s many in America and Europe wore camphor crystals around their necks to ward off infectious diseases and for treatment of respiratory ailments. Camphor is still used to treat colds and help fight bacteria.

However, the Camphor Laurel is one of the most agressive non native pests in several countries like Australia. Not only is the tree choking local fauna, it also releases many toxic chemicals. In fact, camphor itself is toxic when ingested. That is why in the High Court of Australia in 2002, citizens have been given the right to remove any street-side Camphor laurel physically destroying sandstone walls or foundations, and seriously damaging footpaths and gutters.
