Invasive alien plant species (IAPs) are plants that have migrated from one geographical region to non-native region either intentional or unintentional. The general view of IAPs in environment is regarded as destructive to the ecosystem and they pose threat to native vegetation and species. However, some of these IAPS are utilized by local inhabitants as a substitute for scarce indigenous plants. The aim of the study is to conduct ethnobotanical survey on medicinal usage of invasive plant species in Waterberg District, Limpopo Province, South Africa.
An ethnobotanical survey on invasive plant species was conducted to distinguish species used for the treatment of various ailments in the Waterberg, District in the area dominated by Bapedi traditional healers. About thirty Bapedi traditional healers (30) were randomly selected via the snowball method. A guided field work by traditional healers and a semi-structured questionnaire was used to gather information from the traditional healers. The questionnaire was designed to gather information on the local name of plants, plant parts used and methods of preparation which is administered by the traditional healers.
The study revealed that L., (L.), L., (Haw.) Haw., L., L., and are used for treatment of various diseases such as chest complaint, blood purification, asthma, hypertension and infertility. The most plant parts that were used are 57.6% leaves, followed by 33.3% roots, and whole plant, seeds and bark at 3% each. Noticeably, most of these plants are cultivated (38%), followed by 28% that are common to the study area, 20% abundant, 12% wild, and 3% occasionally. is the most frequently used plant species for the treatment of various ailments in the study area. National Environmental Management Biodiversity Act (NEMBA) (10/2004) and Conservation of Agricultural Resource Act (CARA) were consulted to confirm the invaders status. Only eight plants (60%) are regulated by CARA (10/2004). Of 10 IAPs, 80% (8 species) are listed in both NEMBA and CARA legislation. Only 20% (2 species) are listed in NEMBA alone.
Invasive alien plants are utilized by communities to combat various ailments in humans and these plants can help to reduce pressure on heavily harvested indigenous plant.
外来入侵植物是指那些有意或无意地从一个地理区域迁移到非原生区域的植物。在环境中，外来入侵植物通常被视为对生态系统具有破坏性，它们对本地植被和物种构成威胁。然而，当地居民会利用其中一些外来入侵植物来替代稀缺的本土植物。本研究的目的是对南非林波波省沃特贝格区外来入侵植物的药用情况进行民族植物学调查。
在以巴佩迪传统治疗师为主的地区，对沃特贝格区的外来入侵植物进行了民族植物学调查，以区分用于治疗各种疾病的植物种类。通过滚雪球法随机挑选了约30名巴佩迪传统治疗师。由传统治疗师进行实地指导，并使用半结构化问卷从传统治疗师那里收集信息。该问卷旨在收集有关植物的当地名称、使用的植物部位以及传统治疗师所采用的制备方法等信息。
研究表明，[植物名称1]、[植物名称2]、[植物名称3]、[植物名称4]、[植物名称5]、[植物名称6]、[植物名称7]和[植物名称8]被用于治疗各种疾病，如胸部疾病、血液净化、哮喘、高血压和不孕症。使用最多的植物部位是叶子，占57.6%，其次是根，占33.3%；全株、种子和树皮各占3%。值得注意的是，这些植物中大部分是人工种植的（38%），其次是研究区域常见的（28%）、丰富的（20%）、野生的（12%）和偶尔出现的（3%）。[植物名称9]是研究区域治疗各种疾病最常用的植物种类。查阅了《国家环境管理生物多样性法》（NEMBA）（10/2004）和《农业资源保护法》（CARA）以确认这些植物的入侵物种地位。只有8种植物（60%）受CARA（10/2004）监管。在10种外来入侵植物中，80%（8种）同时被列入NEMBA和CARA法规。只有20%（2种）仅被列入NEMBA。
社区利用外来入侵植物来对抗人类的各种疾病，这些植物有助于减轻对过度采收的本土植物的压力。
