This study is one of the first post-civil war efforts to document traditional botanical knowledge in Bié province, central Angola, in a first step to bring more studies on the use of medicinal plant resources in this area so as to bring new insights into Angolan bio-cultural diversity.
Examine the variety of plant species used for medical purposes, as well as characterize their social and cultural values. Also, it is aimed to compare their uses in the studied region with those in Sub-Saharan Africa and report new ethnomedicinal uses.
We documented traditional medicinal plant knowledge among professional herbalists in two areas in Bié province through participatory observation, semi-structured interviews and transect walks. Ethnobotanical information was quantified based on Use Reports to (1) rate traditional knowledge; and (2) determine most useful taxa.
In total, 10 traditional healers shared information on their knowledge. A total of 87 plant species distributed among 57 genera and 36 botanical families were documented with Fabaceae being the best-represented family with 18 species, followed by Phyllanthaceae (6), Apocynaceae (5), Asteraceae (5), Rubiaceae (5), Lamiaceae (4), and Ochnaceae (3). Most medicinal plants are usually gathered at a distance from human settlements because of the belief in the higher efficacy of 'wild' plants shared by all herbalists. Roots are the most common plant part used (79%), explaining why the consulted herbalists call themselves 'root doctors'.
The culturally most important medicinal species identified in this study, i.e. Securidaca longepedunculata, Garcinia huillensis, Annona stenophylla, Afzelia quanzensis and Strychnos cocculoides, were previously reported for the same use in neighbouring countries and elsewhere in Africa. Our study also indicates that there are several locally valuable species that have not yet been studied for their medical potential, to name a few: Alvesia rosmarinifolia, Diplorhynchus condylocarpon, Eriosema affine, Paropsia brazzaeana, Rhus squalida, Sclerocroton cornutus or Xylopia tomentosa. Moreover, the ethnomedicinal use of 26 species was reported for the first time to sub-Saharan Africa.

这是内战以来首次在安哥拉比耶省记录传统植物学知识的努力之一，旨在为该地区药用植物资源的更多研究奠定基础，以便深入了解安哥拉的生物文化多样性。
研究用于医疗目的的植物物种多样性，并对其社会和文化价值进行特征描述。此外，还旨在比较研究区域内的植物用途与撒哈拉以南非洲地区的植物用途，并报告新的民族医学用途。
我们通过参与式观察、半结构化访谈和样带步行，在比耶省的两个地区记录了专业草药医生的传统药用植物知识。根据使用报告，采用（1）传统知识评分；（2）确定最有用的类群，对民族植物学信息进行量化。
共有 10 位传统治疗师分享了他们的知识信息。共记录了 87 种植物，分布在 57 个属和 36 个科中，其中豆科植物种类最多，有 18 种，其次是叶下珠科（6）、夹竹桃科（5）、菊科（5）、茜草科（5）、唇形科（4）和铁青树科（3）。大多数药用植物通常是在远离人类住区的地方采集的，因为所有草药医生都相信“野生”植物的疗效更高。根是最常用的植物部分（79%），这解释了为什么咨询的草药医生自称为“根医生”。
本研究中确定的文化上最重要的药用物种，即长柄山海棠、安哥拉藤黄、窄叶光叶海桐、非洲轻木和地构叶，此前在邻国和非洲其他地区也有相同的用途报道。我们的研究还表明，还有一些当地有价值的物种尚未研究其医疗潜力，仅举几例：罗迷香、二翅豆、含羞草、拟黧豆、白背叶、肉实树或绒毛叶黄皮。此外，26 种植物的民族医学用途首次被报道用于撒哈拉以南非洲。
