Herbal medicines: a cross-sectional study to evaluate the prevalence and predictors of use among Jordanian adults

Abstract

Introduction: Understanding why adults resort to herbal medicine can help in planning interventions aimed at increasing awareness regarding herbal use. This study sought to investigate the prevalence and to determine factors for predicting the use of herbal medicine among Jordanian adults. Methods: A cross-sectional study was conducted involving 378 older adults who were randomly selected from two different areas of Jordan. A questionnaire was used to gather data and validation criteria for validity and reliability of the content were tested by content and face validity in a panel of experts. Results: From a total of 500 invited participants, 378 completed the questionnaire. The prevalence of the use of of herbal products in this study was high at 80.2%. Herbal medicines use was not associated with any demographic factors other than age (p < 0.05). Moreover, the only associated health-related characteristic was the patient's disease state including, notably, hypertension (p < 0.05). Reasons for not using herbal medicines as reported by nonusers included mainly a lack of belief in their efficacy (52.2%). Another two important reasons were that the individuals believed themselves to healthy and have no need for their use (31.3%) and the unavailability of enough information about the herbal medicines (29.7%). Finally, the most common side effects as reported by patients in this study were nausea and vomiting (9.3%), and, to a lesser extent, skin rash (2.1%). Conclusion: There is a high rate of use of herbal medicines in Jordan, especially among hypertensive patients. Therefore, there is a need to establish effective herbal medicine policies and health education programs to discuss the benefits and risks of herbal medicine use, with the aim of maximizing patient-desired therapeutic outcomes.

Prevalence of using herbs and natural products as a protective measure during the COVID-19 pandemic among the Saudi population: an online cross-sectional survey

“…The current study reported that the most frequently consumed herbs and natural products among the old age group were black seeds, ginger, garlic, and chilli pepper, whereas honey and murrah were more popular in the young age group. This finding is supported by a recent study in Jordan, which also reported that herbal medicine use was not associated with any demographic factors other than age ( El-Dahiyat et al, 2020 ). This might be due to the extreme difference in the daily life of the two age groups or their different flavour preferences.…”

The perception of Jordanian population towards concomitant administration of food, beverages and herbs with drugs and their possible interactions: A cross‐sectional study

“…21,31 Seventy percent of the study's participants used plants and herbs to improve their health, which is high and similar to the finding of another study conducted in Jordan to evaluate the prevalence and predictors of herbal medicine use where the prevalence was found to be 80.2%. 32 This study revealed that the majority of participants acknowledged the importance of medicinal plants and herbs in treating diseases. This shows an agreement with the findings of similar studies conducted in Morocco, 33 Tanzania, 34 the United Kingdom, 17 and Surinamese migrants in the Netherlands.…”
