And the scientific research showed that they are medicable to insomnia, anxiety and other diseases that found in modern people. 4 The regression models of biomass were used to calculate the total cumulative biomass. Average biomass of six samples was 62.88 t·hm-2 after cutting 3 years, which was higher than that of tropical secondary forests with 5 years succession. It can be concluded that traditional fuel woods had played an important role in conservation of tropical forest in the area. Caloric values were not different in major fuel species (Coefficient of variation was only 1.1%). The similar result was found in stems of C. siamea after growing different years. The main reason of C. siamea cultivation was that it had the character of hardwood, easy collecting, little ash, and so on.
