The purpose of this study is to determine the blood pressure (BP) lowing potential of some herbs used by the indigenous people of Zango Kataf, Kaduna State, Nigeria, to treat hypertension.
A total of 17 herbal healers and 15 hypertensive patients who use herbs to treat hypertension in Zango Kataf, Kaduna State, Nigeria, were consulted between 2019 and 2020. Participants were selected via purposeful sampling. BP was measured before and after the ingestion of a herbal preparation. Three plant preparations were screened: Newbouldia laevis, Hibiscus cannabinus and Pavetta crassipes.
H. cannabinus produced a significant decrease of 16, 12 and 14 mmHg in SBP at 2, 3 and 4 h, respectively (p = 0.001 at 2 h, p = 0.04 at 3 h, p = 0.01 at 4 h). While P. crassipes produced a significant decrease in SBP of 12, 15, 19 and 20 mmHg at 1, 2, 3 and 4 h, respectively (p = 0.04 at 1 h, p= 0.00 at 2 h, p = 0.00 at 3 h and p = 0.00 at 4 h). The findings for N. laevis were not reported due to incomplete information.
The sample size of this study was small. The researcher could not meet with some hypertensive clients owing to the poor cooperation of some herbal healers. Further, some hypertensive patients rejected the offer to participate in the study.
This study reveals that treatment with H. cannabinus and P. crassipes significantly decrease BP in hypertensive patients.
