**4. Discussion**

Ethnobotanical information gathered were quantitatively analyzed using various quantitative indices which made up of: Relative frequency of citation (RFC) and Frequency of citation (FC) [14, 16]. It has been proved that, the RFC was happened to be (0.25) for the gastrointestinal disorders among the collated medicinal plants [13], which conforms to the present study as pinpointed in **Table 2**. It has been revealed that, 80% of African populace relied on herbal/traditional medicine to treat many ailments due to the in availability and affordability of the commercial orthodox. In Northern Nigeria, people make used of combined plants formulations to get rid of gastric ulcer problem, which include *A. nilotica, Balanites aegyptiaca* and *Ziziphus abyssinica* extracts, have been concluded and validated that, using combined plants formulations showed sound activity than using individual plants in treating ulcer [17]. *Gueira senegalensis* has been in records and used by traditional practitioners as medicine in many parts of West Africa including Nigeria. The latter confirms the present study as shown in **Table 1**. Its leaves were taken for many purposes like; pulmonary and respiratory problems, colic and diarrhea, syphilis, beriberi, leprosy, rheumatism, diuresis, impotence and expurgation [16]. Furthermore, its roots and bark have been used in treating diarrhea, dysentery and abdominal pain which was found worthy that, the whole plant has pharmacological attributes by serving as antimicrobial, analgesic, anti-inflammatory and also applicable to address animals' ailments and their supplements as diet [18]. Over utilization made some to be in an extinction due to the lack of enforced law [5], which is similar to the current study as shown in (**Figure 3**) the effect of over destruction or deforestation of plant species.
