Nole Tsabang, Clement G Yedjou and Paul B Tchounwou

Objective: High blood pressure is a public health challenge worldwide. According to World Health Organization, 30% of men and 50% of women 65 to 75 years old are suffering from high blood pressure. The number of hypertensive patients in the world will attain 1.56 billion of people, with 60% increase in prevalence. The incidence of high blood pressure increases with age, but nowadays, is being noticed an increasing incidence in young people. The sociocultural medicine may provide new solutions in the management of this pathology. Therefore this study was carried out to record and document plants used against high blood pressure in socio-cultural medicine for future drugs discovery worldwide. Methods: An ethno botanical survey was realized between 2002 and 2016 to identify manifold plants used to fight against high blood pressure. This survey was carried out in three phytogeographic regions of Cameroon. Amongst people living in those regions, 1131 randomly screened interviewees distributed in 58 socio-cultural groups were involved in this study. Results: This survey reveals that about 70% of interviewees don’t know high blood pressure which is a symptomless disease. A total of 28 species of plants were recorded. These plants belong to 25 genera and 24 families. They were used to prepare 28 herbal remedies for the treatment of high blood pressure. In the morphological point of view about 10/28 (36%) plants are herbs; 9/28 (32%) plants are trees and 9/28 (32%) plants are shrubs. Only 3/28 plants (11%) used including Allium sativum, Aloe barteri and Aloe buttneri) are cultivated. This means that the plants used in this study don’t usually have some form of protection through cultivation which is encouraging in terms of their conservation. Conclusion: The uncontrolled use of a hypotensive plants can provoke a fatal hypotension in hypertensive patients. Therefore the use of hypotensive plants needs to be controlled by physician or by a patient verification using a blood pressure monitor. Recorded species which will slow the high blood pressure will be used for the preparation of phytodrugs.
