Camphor tree – air purification
Camphor tree, also known as wild incense tree, scientific name is Cinnamomum camphora (L.) Presl. Large trees can grow up to 40 meters, reaching 200cm diameter. In Vietnam camphor grows relatively slowly. Flowering season 3-4 months, 10-11 months results season. Is relatively light demanding plants, shade childhood, warm and humid climate preferred average temperature of 15- 20 ° C, over 1,000 mm of rainfall.

It is by steam distillation of crushed wood, roots, shoots the camphor tree to get the oil, from which in the process of condensing and cooling can collect up to 90% camphor. By fractional distillation of crude oil yielded different ingredients, used in engineering ( “red camphor oil”, contain safrole), health (medical camphor), marinated pineapple ( “white camphor essential oil”).
Previously, many trees were cut down for the production of natural camphor serve for use in health care, but now all kinds of camphor in actual use synthetic origin. Sawdust and shavings from it can also produce camphor oil.
