Traditionally used herbal medicines with antibacterial effect on Aggegatibacter actinomycetemcomitans: Boswellia serrata and Nigella sativa

Effects of Frankincense Compounds on Infection, Inflammation, and Oral Health

Boswellia trees, found throughout the Middle East and parts of Africa and Asia, are the source of frankincense oil. Since antiquity, frankincense has been traded as a precious commodity, but it has also been used for the treatment of chronic disease, inflammation, oral health, and microbial infection. More recently, the bioactive components of Boswellia trees have been identified and characterized for their effects on cancer, microbial infection (especially infection by oral pathogens), and inflammation. Most studies have focused on cell lines, but more recent research has also investigated effects in animal models of disease. As natural products are considered to be safer than synthetic drugs, there is growing interest in further developing the use of substances such as frankincense oil for therapeutic treatment.

Beneficial Effects on Abdominal Bloating with an Innovative Food-Grade Formulation of Curcuma longa and Boswellia serrata Extracts in Subjects with Irritable Bowel Syndrome and Small Bowel Dysbiosis

Bloating is a symptom frequently reported by subjects with irritable bowel syndrome (IBS) and small bowel dysbiosis, and Low FODMAP’s diet (LFD) has been used to treat them. Extracts of Curcumalonga and Boswelliaserrata share anti-inflammatory and antimicrobial effects that could be useful in the management of these clinical conditions. The aim of this study was to evaluate the efficacy of curcumin and boswellia extracts (as Curcumin Boswellia Phytosome, CBP) and LFD on the relief of abdominal bloating in IBS subjects with small bowel dysbiosis, in comparison to LFD alone, in a 30-day supplementation, randomized trial. IBS participants were randomized to either the intervention (500 mg bid of CBP and LFD) or control arm (LFD). Small bowel dysbiosis has been defined by an increase of urinary indican with normal urinary skatole. A total of 67 subjects were recruited. The intervention group (33 subjects) showed a significant decrease (p < 0.0001) of bloating, abdominal pain, and indican values at the end of the study, when compared to the control group (34 subjects). Moreover, the subjects of the intervention group showed a significantly better (p < 0.0001) global assessment of efficacy (GAE) as compared to controls. In conclusion, in subjects with IBS and small bowel dysbiosis, abdominal bloating can be successfully reduced with a supplementation with CBP and LFD.

Boswellic acids/Boswellia serrata extract as a potential COVID-19 therapeutic agent in the elderly

The most severe cases of COVID-19, and the highest rates of death, are among the elderly. There is an urgent need to search for an agent to treat the disease and control its progression. Boswellia serrata is traditionally used to treat chronic inflammatory diseases of the lung. This review aims to highlight currently published research that has shown evidence of potential therapeutic effects of boswellic acids (BA) and B. serrata extract against COVID-19 and associated conditions. We reviewed the published information up to March 2021. Studies were collected through a search of online electronic databases (academic libraries such as PubMed, Scopus, Web of Science, and Egyptian Knowledge Bank). Several recent studies reported that BAs and B. serrata extract are safe agents and have multiple beneficial activities in treating similar symptoms experienced by patients with COVID-19. Because of the low oral bioavailability and improvement of buccal/oral cavity hygiene, traditional use by chewing B. serrata gum may be more beneficial than oral use. It is the cheapest option for a lot of poorer people. The promising effect of B. serrata and BA can be attributed to its antioxidant, anti-inflammatory, immunomodulatory, cardioprotective, anti-platelet aggregation, antibacterial, antifungal, and broad antiviral activity. B. serrata and BA act by multiple mechanisms. The most common mechanism may be through direct interaction with IκB kinases and inhibiting nuclear factor-κB-regulated gene expression. However, the most recent mechanism proposed that BA not only inhibited the formation of classical 5-lipoxygenase products but also produced anti-inflammatory LOX-isoform-selective modulators. In conclusion a small to moderate dose B. serrata extract may be useful in the enhancing adaptive immune response in mild to moderate symptoms of COVID-19. However, large doses of BA may be beneficial in suppressing uncontrolled activation of the innate immune response. More clinical results are required to determine with certainty whether there is sufficient evidence of the benefits against COVID-19.

Repurposing of the Herbals as Immune-Boosters in the Prevention and Management of COVID-19: A Review

Coronavirus disease (COVID) is highly contagious, and negligence of it causes high morbidity and mortality globally. The highly infectious viral disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was abbreviated as COVID-19 (Coronavirus disease 2019) by World Health Organization first time on February 11, 2020, and later on, WHO declared COVID-19 as a global pandemic on 11/3/2020. Epidemiological studies demonstrated that the SARS CoV-2 infects the overall population, irrespective of age, gender, or ethnic variation, but it was observed in clinical studies that older and compromised immunity population is much more prone to COVID-19. SARS-CoV-2 majorly spread through aeration route in droplet form on sneezing and coughing, or by contact when touching eyes, nose or mouth with the infected hands or any other organs, resulting from mild to severe range of SARS-CoV-2 infection. This literature-based review was done by searching the relevant SCI and SCOPUS papers on the pandemic, SARS-CoV-2 and COVID-19, herbal formulation, and Ayurveda from the databases, Academia, Google Scholar, PubMed, and ResearchGate. The present review attempts to recognize the therapeutic strategies to combat COVID-19 because of the current human risk. Indian system of medicine, including herbals, has immense potential in treating and managing various viral infections and provides evidence to utilize Ayurvedic medication to improve immunity. Cumulative research findings suggest that Ayurvedic formulations and herbal immunomodulators (Tino sporacordifolia, Withania somnifera, Crocus sativus, Zafran, Allium sativum, Zingiber officinale, Albizia lebbek, Terminalia chebula, Piper longum, Mangifera indica, Ocimum sanctum, Centella asiatica ) are promising in the treatment of outrageous viral infections without exerting adverse effects. Considering the ancient wisdom of knowledge, the herbal formulations would compel healthcare policymakers to endorse Ayurveda formulations to control the COVID-19 pandemic significantly.

Current herbal medicine as an alternative treatment in dentistry: In vitro, in vivo and clinical studies

Since the time that human population comprehended the importance of general health maintenance and the burden of disease, there has been a search for healing properties in the natural environment. Herbal medicine is the use of plants with medical properties for prevention and treatment of conditions that can affect general health. Recently, a growing interest has been observed toward the use of traditional herbal medicine alongside synthetic modern drugs. Around 80% of the population, especially in developing countries relies on it for healthcare. Oral healthcare is considered a major part of general health. According to the world health organization (WHO), oral health is considered an important part of general health and quality of life. The utilization of natural medications for the management of pathologic oro-dental conditions can be a logical alternative to pharmaceutical methods due to their availability, low costs, and lower side effects. The current literature review aimed at exploration of the variety and extent of herbal products application in oral health maintenance including different fields of oral healthcare such as dental caries, periodontal maintenance, microbial infections, oral cancers, and inflammatory conditions.

An evaluation of the efficacy of ethanolic extract of Nigella sativa L. (Kalonji) on the clinical parameters of moderate‑to‑severe gingivitis: A split‑mouth clinical study

Introduction

Gingivitis is a relatively innocuous and reversible inflammation of gingiva. If left untreated, it might progress involving the deeper supporting periodontal tissues of the tooth with consequent mobility and tooth loss. Compelling literature has suggested the role of local antibacterial and anti‑inflammatory agents as an adjunct to scaling and root planing (gold standard) for treating periodontal diseases. Various herbs such as Nimba (Azadirachta indica A. Juss), Babbula (Vachellia nilotica (L.) P.J.H. Hurter & Mabb.) and turmeric (Curcuma longa L.) have been used for gingivitis since ancient times. Nigella sativa L. (Kalonji) is one such herb known for its remarkable anti‑inflammatory, antioxidant and antimicrobial properties and thus has been utilized in the present study.

Aim

The aim of the study was to explore the clinical efficacy of different ethanolic solutions of N. sativa in moderate‑to‑severe gingivitis patients.

Materials and Methods

It is a split‑mouth clinical study with 24 patients of moderate‑to‑severe gingivitis from the age group of 25-45 years. Recruited individuals were divided in to group I₁, group II₁ and group III₁ (scaling and root planning i.e., control) and group I₂, group II₂ and group III₂ (experimental). Three doses of solution 1 (1:3), solution 2 (1:1) and solution 3 (3:1) were administered to the experimental groups for 3 consecutive days. The clinical parameters, i.e., gingival index (GI) and plaque index (PI) were recorded at baseline, 14 days and 28 days in all the individuals. ANOVA test was used in the study for statistical analysis.

Results

Intergroup comparison in terms of GI showed statistically significant difference at 14^th and 28^th day from baseline between I_{1 &}I_2, at only 28^th day between II₁ & II₂ and insignificant difference between III₁ & III₂ at all time intervals from baseline. On intragroup comparison, statistically significant reduction in GI in all groups from baseline till 28 days was found, but among experimental groups best result was seen in group III₂ (P < 0.001; F value 153.75). As far as PI is concerned, intergroup comparison between different groups displayed statistically significant difference from baseline to 14^th and 28^th day between all groups i.e I₁& I₂, II₁& II₂ and III₁& III₂. On intragroup comparison, statistically significant reduction in PI in all control groups i.e I_1, II₁ & III₁ was found, but among experimental groups only group III₂ provided statistically significant reduction (P < 0.001, F value 30.40).

Conclusion

The results of this study indicate that, the ethanolic extract of N. sativa is effective in the treatment of moderate to severe gingivitis.

Determination of progesterone compounds in the crude methanol extract of benalu duku leaves

Background and Aim:

Dendrophthoepentandra L. Miq (benalu duku) is a parasitic herb that commonly grows on the host plant Lansium domesticum. Researchers have found that the plant contains anticancer compounds and may contain phytoandrogens, including progesterone-like compounds, in its crude methanol extract. The objective of the current study was to investigate the compound of phyto progesterone in benalu duku leaves after extracted by methanol and prepared using an analytical column of high-performance liquid chromatography (HPLC).

Materials and Methods:

About 400 g of benalu duku leaves were pulverized, and their compounds were isolated by the isocratic method using an RP-18 analytical column (5 µm) with a mobile phase of 70:30 (methanol: water) in a photodiode array detector adjusted to 254 nm. The phyto progesterone compound was identified at a retention time of approximately 6.01 min.

Results:

By LC-electrospray ionization mass spectrometry focusing on molecular fractions, the fingerprint area of the Fourier transform-infrared spectroscopy (FT-IR, cm⁻¹) and ^Hnuclear magnetic resonance (NMR) spectra indicated that the phyto progesterone product isolated was identical to the certified reference material of pure progesterone, particularly the specific functional groups in the FT-IR spectrum at wavenumbers of 1317.43 cm⁻¹ and 1386.86 cm⁻¹ and in the proton ^HNMR spectrum at carbon 21 of progesterone (p<0.05).

Conclusion:

Each 49.888 µg/mL of crude benalu duku leaf extract dissolved in the mobile phase contained 28.515±0.713 µg/mL phyto progesterone.
