Dau Tram

Another forest product from Central Vietnam is eucalyptus oil, or "dau tram", which is used medicinally for a variety of different afflictions, e.g. bronchitis, bacterial infections, and asthma. It is also an effective insect repellent, which is probably why Mr. Thanh and Ms. Ngoc, student assistants who were helping with the rattan project and getting bit my mosquitos, stopped at the roadside stall in Quang Tri province shown below. 

The oil is extracted from several different species of Eucalyptus. Like Acacia (see Forests of Vietnam II) and Pinus (see Naval Stores), Eucalyptus has been extensively planted throughout the Central Truong Son Mountains to reforest denuded areas. Go here for an FAO report on the history of Eucalyptus in Vietnam. [NOTE: Ms. Ngoc doesn't seem so pleased with the smell of this Dau Tram.  They ended up not buying it].
