This study uses the utilitarian redundancy model as a basis to investigate issues related to the preference for plants native to the Caatinga used as anti-inflammatories by respondents from the community of Carão in rural Pernambuco, Brazil.
For this purpose, 49 respondents and 24 native plants used as anti-inflammatories were selected from a database built by previous studies in this study area. Interviews with respondents were conducted by applying the checklist-interview technique and by presenting photographs of plants, which were ordered according to plant preference for each type of inflammation mentioned. After elaborating each list of preferences, we inquired as to the criteria used for the construction of the lists. A salience index was calculated to determine the most- and least-preferred species, and principal component analysis (PCA) was used to identify the most significant criteria used by the respondents to indicate the preferred plants for anti-inflammatory use.
We identified 37 subcategories or inflammatory conditions, most of which were associated with disorders of the genitourinary (8 conditions), digestive (7) and respiratory (4) systems. Subcategories with the highest level of redundancy include "wound" (79.1% of species), "cut" (66.6%) and "uterus" (66.6%), and five non-redundant conditions were identified (only one species). We obtained approximately 300 lists and 18 choice criteria. PCA analysis showed that seven species were most preferred by the respondents, as they showed the highest salience values, and that the preferred criterion was "treatment effectiveness".
These results indicate that inflammation is a complex collection of disorders consisting of several subcategories. Furthermore, respondents preferred different treatments for different inflammatory conditions, which pose a challenge for future pharmacological studies that aim to assess the biological activity of anti-inflammatory plants. Preferences were very specific, focused on a small number of species and mainly related to therapeutic effectiveness.
本研究利用功利冗余模型作为基础，调查与巴西伯南布哥州卡劳社区受访者对源自卡廷加的抗炎植物偏好相关的问题。
为此，从该研究区域先前研究中建立的数据库中选择了 49 名受访者和 24 种用作抗炎药的本地植物。通过应用清单访谈技术和展示植物照片对受访者进行访谈，这些照片根据受访者对每种提到的炎症类型的植物偏好进行排序。在详细列出每个偏好列表后，我们询问了构建列表所使用的标准。计算了显著指数以确定最受欢迎和最不受欢迎的物种，并进行主成分分析（PCA）以确定受访者用来表示抗炎用途的首选植物的最重要标准。
我们确定了 37 个亚类或炎症状况，其中大多数与泌尿生殖系统（8 种情况）、消化系统（7 种）和呼吸系统（4 种）的疾病有关。具有最高冗余性的亚类包括“伤口”（79.1%的物种）、“切口”（66.6%）和“子宫”（66.6%），并确定了五种非冗余条件（只有一种物种）。我们获得了大约 300 个列表和 18 个选择标准。PCA 分析表明，有 7 种物种最受受访者欢迎，因为它们具有最高的显著值，并且首选标准是“治疗效果”。
这些结果表明，炎症是一组复杂的疾病，由几个亚类组成。此外，受访者对不同的炎症状况选择了不同的治疗方法，这对未来旨在评估抗炎植物生物活性的药理学研究构成了挑战。偏好非常具体，集中在少数几种物种上，主要与治疗效果有关。
