While mention of the camphor tree ([phrase omitted], Lauracceae family), a plant native to the sub-tropical zone of China, occurs as early as the Warring States period (495-221 BC), there is relatively little information on camphor resin (dryobalanops
aromatica) in the Chinese textual corpus prior to the Tang dynasty.
Ho et al., "Preliminary assessment on the growth performance of Dryobalanops
beccarii dyer planted under enrichment planting technique at Gunung Apeng Forest Reserve," Kuroshio Science, vol.
miltiorrhiza, Panax notoginseng, and Dryobalanops
camphora, showed much more apparent efficacy compared to isosorbide dinitrate .
Moura-Costa and Lundoh (1994) treated Dryobalanops
lanceolata cuttings with 2,4-D in concentrations of 2000, 8000, and 30000 mg x [L.sup.-1] and observed a reduced rooting percentage with an increasing concentration that they attributed to the phytotoxic effect of this powerful auxin when applied in high concentrations creating an herbicidal effect.
grandiflora are higher than those found in Dryobalanops
lanceolata in Malaysia (Breulmann et al., 1998); Lycopersicum esculentum in Italy (Spalla et al., 2009); and Sasa nipponica, Taxodium japonicum, Thea sinensis and Populus sieboldii in Japan (Fu et al., 2001) but lower than values reported in six REE-accumulator fern species in China (Zhang et al., 2002).
And borneolum synthcticum is the resin product of Dryobalanops
aromatica Gaertn.f., which is also a regular refreshing and resuscitating drug commonly used for treatment of stroke, phlegm, coma, or related diseases.
Camphor, or Dryobalanops
aromatica, like birds' nests, was another product sold for the luxury Chinese market and with a long place in history, perhaps being known to Arab and Portuguese traders as well as Chinese, with camphor from the Baram being known as of the desired quality.
(4) While eastern Johor was deficient in good harbours, the restriction on the peninsula of camphor trees (Dryobalanops
aromatica L.) to that area encouraged forest product trade there.
Previous studies have explored the effects of individual herbs and found that Dryobalanops
aromatica, Capsicum frutescens, Cinnamomum cassia and Panax notoginseng have anti-inflammatory effects on various soft tissue conditions (Akira, 1987; Kubo et al., 1996; Li and Chu, 1999; Han et al., 2001).
camphor was highly valued in the Sung period, but was never placed on the same footing as gharuwood or frankincense.
