The current study was conducted to explore the relationship between property of traditional Chinese medicines (TCM) and the light conditions of their original plant in habitats and advance a "light-cold and heat property" hypothesis under the guidance of theory of TCM. In the present study, we selected 127 common Chinese herbs. Association rules mining method was used to find out the association relationship between the cold-heat properties of different TCM and the habitats of their original plant, while using statistical methods to analyze the correlation between light condition and cold-heat property of TCM based on the description of the habitats in the Flora of China and investigation. The results showed that the habitats associated to TCM with cold property are in the order of grassland>curb>hillside>wasteland>gully>farmland>riverside. The habitats that associated to TCM with heat property are: undergrowth>shrub>gully>jungle. For 68 TCMs with cold property, 81.2% of their original plants are light-demanding, 8.7% are shade-demanding, and 8.7% of them showed no obvious light preference. For 59 TCMs with heat property, 62.7% of their original plants are shade-demanding, 20.3% are shade-demanding, and 17.0% of them showed no obvious light preference. Meanwhile, Chi-square test showed that there was a significant difference between the cold-heat property and light preference (<0.01). In summary, there is a significant correlation between the light preference of TCM original plants and their cold-heat properties. In order to ensure the pharmacological effect of TCM, the relationship between the light conditions and the properties of TCM should be considered in the cultivation of medicinal plants for TCM.
本研究旨在探讨中药特性与其原生植物在栖息地的光照条件之间的关系，并在中医理论指导下提出“光寒热属性”假说。在本研究中，我们选取了127种常见的中药材。采用关联规则挖掘方法找出不同中药的寒热属性与其原生植物栖息地之间的关联关系，同时基于《中国植物志》中对栖息地的描述和调查，运用统计方法分析光照条件与中药寒热属性之间的相关性。结果表明，与寒性中药相关的栖息地依次为草地＞路边＞山坡＞荒地＞沟壑＞农田＞河边。与热性中药相关的栖息地为：林下＞灌丛＞沟壑＞丛林。对于68种寒性中药，其原生植物中81.2%喜光，8.7%喜阴，8.7%无明显光照偏好。对于59种热性中药，其原生植物中62.7%喜阴，20.3%喜光，17.0%无明显光照偏好。同时，卡方检验表明寒热属性与光照偏好之间存在显著差异（＜0.01）。综上所述，中药原生植物的光照偏好与其寒热属性之间存在显著相关性。为确保中药的药理作用，在中药材种植中应考虑光照条件与中药属性之间的关系。
