Choi D, Im HB, Choi SJ, Han D. Safety classification of herbal medicine use among hypertensive patients: a systematic review and meta-analysis. Front Pharmacol 2024; 15:1321523. [PMID: 38881876 PMCID: PMC11176523 DOI: 10.3389/fphar.2024.1321523] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Accepted: 03/27/2024] [Indexed: 06/18/2024] Open
Abstract
Background The use of herbal medicines (HMs) for the treatment of hypertension (HTN) is increasing globally, but research on the potential adverse effects and safety of HMs in HTN patients is limited. Therefore, this systematic review and meta-analysis aim to determine the global prevalence of HM usage among HTN patients and assess the safety of identified herbs based on current scientific evidence. Methods The PubMed/MEDLINE, EMBASE (Ovid), and Cumulated Index to Nursing and Allied Health Literature (CINAHL) databases were searched for cross-sectional studies on the use of HM among HTN patients. Our review includes studies published in English up to the year 2023. After extracting and appraising the data from the studies, a meta-analysis was conducted using the Stata version 16.0 to estimate the pooled prevalence of HM use in patients with HTN (PROSPERO: CRD42023405537). The safety classification of the identified HM was done based on the existing scientific literature. Results This study analyzed 37 cross-sectional studies from 21 countries and found that 37.8% of HTN patients used HM to manage their health. The prevalence of HM use varied significantly based on publication year and geographical region. Among the 71 identified herbs, Allium sativum L., Hibiscus sabdariffa L., and Olea europaea L. were the most commonly used. However, four herbs were identified as contraindicated, 50 herbs required caution, and only 11 herbs were considered safe for use. Conclusion The study highlights the potential risks of toxicities and adverse effects associated with HM use in the treatment of HTN. Ensuring patient safety involves using safe HMs in appropriate doses and avoiding contraindicated HMs. Future research should focus on identifying commonly used herbs, especially in resource-limited countries with poor HTN management, and additional clinical research is required to assess the toxicity and safety of commonly used HMs.

Adarthaiya S, Sehgal A. Moringa oleifera Lam. as a potential plant for alleviation of the metabolic syndrome-A narrative review based on in vivo and clinical studies. Phytother Res 2024; 38:755-775. [PMID: 38015048 DOI: 10.1002/ptr.8079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 11/06/2023] [Accepted: 11/10/2023] [Indexed: 11/29/2023]
Abstract
The metabolic syndrome (MetS) refers to the co-occurrence of risk factors, including hyperglycaemia, increased body weight, hypertension and dyslipidemia, which eventually lead to diabetes and cardiovascular disease, a common health problem worldwide. Recently, there has been an increasing interest in the use of plant-based products for the management of MetS, because of their less detrimental and more beneficial effects. Moringa oleifera (Moringaceae), commonly known as drumstick, is cultivated worldwide for its nutritional and medicinal properties. This review focuses on the in vivo and human studies concerning the potential of M. oleifera in the alleviation of MetS and its comorbidities. The search for relevant articles was carried out in PubMed and Google Scholar databases. Randomised controlled and clinical trials from the PubMed database were included in this review. The results suggested that the administration of M. oleifera, in vivo, shows clear signs of improvement in MetS indices. Despite fewer human studies, the existing data documented convincing results that uphold the potential of M. oleifera against MetS. Therefore, future research discussing the probable mechanism of action is much needed which could further assure the usage of M. oleifera in the treatment regimen of MetS.

MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27030678. [PMID: 35163945 PMCID: PMC8840448 DOI: 10.3390/molecules27030678] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 01/13/2022] [Accepted: 01/18/2022] [Indexed: 11/16/2022]
Abstract
Moringa oleifera leaves have been widely used for the treatment of inflammation, diabetes, high blood pressure, and other diseases, due to being rich in polyphenols. The main objective of this work was to largely separate the main polyphenols from Moringa oleifera leaves using the technique of high-speed counter-current chromatography (HSCCC). The phenolic composition in Moringa oleifera leaves was first analyzed qualitatively and quantitatively by UPLC-Q-Exactive Orbitrap/MS and UPLC-QqQ/MS, respectively, indicating that quercetin and kaempferol derivatives, phenolic acid and apigenin are the main polyphenols in Moringa oleifera leaves, with quercetin and kaempferol derivatives predominating. Furthermore, the conditions of HSCCC for large-scale separation of polyphenols from Moringa oleifera leaves were optimized, which included the selection of the solvent system, flow rate and the sample load. Only by one-step HSCCC separation (within 120 min) under the optimized conditions, six quercetin and kaempferol derivatives, a phenolic acid and an apigenin could be individually isolated at a large scale (yield from 10% to 98%), each of which possessed high purity. Finally, the isolated polyphenols and phenolic extract from Moringa oleifera leaves (MLPE) were verified to have strong neuroprotective activities against H2O2-induced oxidative stress in PC-12 cells, suggesting that these compounds would contribute to the main beneficial effects of Moringa oleifera leaves.

Bailey-Shaw Y, Rodney S, Golding C, Foster S, Randle M, Watson C. The Potential Applications of Moringa oleifera Leaves in Functional Herbal Beverages: A Review of its Nutritional, Medicinal, and Toxicity Profiles. CURRENT NUTRITION & FOOD SCIENCE 2021. [DOI: 10.2174/1573401316999200802182952] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/22/2022]
Abstract
:
In recent times, Moringa oleifera Lam. has become one of the most sought after therapeutic
cure-all plants in tropical and subtropical zones, including Jamaica. Anecdotally, the most
popular choice of Moringa consumption locally is in the form of functional herbal beverages, such
as teas and juices, prepared from the leaves of the plant. However, there is little or no scientific evidence
to validate the efficacy and or safety of such beverages.
:
An extensive search of scientific literature published over the last decade (2010-2020) related to
the nutritional, medicinal, and toxicological profiles of Moringa oleifera was, therefore conducted
with special emphasis on literature related to the dried leaves and aqueous leaf extracts thereof.
Google Scholar, Science Direct, and PubMed databases were the main search tools employed. Articles
that referred to varieties of Moringa, other than oleifera, were excluded from the searches, as
were articles that referred to subject matters outside of nutrition, medicinal properties, and toxicity.
All peer-reviewed journal articles, and other online articles, which referred to the subject matters of
interest were critically read and included in the review.
:
This review is a compilation of evidence-based literature, indicating the outstanding nutritive value,
high therapeutic potential, and the relatively non-toxic properties of the dried leaves and aqueous
leaf extracts of Moringa oleifera. Prospects for their application in the development of safe and
efficacious functional herbal beverages are indicated.
