ABSTRACT

Tulsi (Holy basil, Ocimum tenuiflorum L., Lamiaceae), native to Asia, has become globalised as the cultural, cosmetic, and medicinal uses of the herb have been popularised. DNA barcoding, a molecular technique used to identify species based on short regions of DNA, can discriminate between different species and identify contaminants and adulterants. This study aimed to explore the values associated with Tulsi in the United Kingdom (UK) and authenticate samples using DNA barcoding. A mixed methods approach was used, incorporating social research (i.e., structured interviews) and DNA barcoding of Ocimum samples using the ITS and trnH-psbA barcode regions. Interviews revealed the cultural significance of Tulsi: including origins, knowledge exchange, religious connotations, and medicinal uses. With migration, sharing of plants and seeds has been seen as Tulsi plants are widely grown in South Asian (SA) households across the UK. Vouchered Ocimum specimens (n = 33) were obtained to create reference DNA barcodes which were not available in databases. A potential species substitution of O. gratissimum instead of O. tenuiflorum amongst SA participants was uncovered. Commercial samples (n = 47) were difficult to authenticate, potentially due to DNA degradation during manufacturing processes. This study highlights the cultural significance of Tulsi, despite a potential species substitution, the plant holds a prestigious place amongst SA families in the UK. DNA barcoding was a reliable way to authenticate Ocimum species.

ABSTRACT

Background: Curcumin, quercetin, and vitamin D3 (cholecalciferol) are common natural ingredients of human nutrition and reportedly exhibit promising anti-inflammatory, immunomodulatory, broad-spectrum antiviral, and antioxidant activities. Objective: The present study aimed to investigate the possible therapeutic benefits of a single oral formulation containing supplements curcumin, quercetin, and cholecalciferol (combinedly referred to here as CQC) as an adjuvant therapy for early-stage of symptomatic coronavirus disease 2019 (COVID-19) in a pilot open-label, randomized controlled trial conducted at Mayo Hospital, King Edward Medical University, Lahore, Pakistan. Methods: Reverse transcriptase polymerase chain reaction (RT-PCR) confirmed, mild to moderate symptomatic COVID-19 outpatients were randomized to receive either the standard of care (SOC) (n = 25) (control arm) or a daily oral co-supplementation of 168 mg curcumin, 260 mg quercetin, and 9 µg (360 IU) of cholecalciferol, as two oral soft capsules b.i.d. as an add-on to the SOC (n = 25) (CQC arm) for 14 days. The SOC includes paracetamol with or without antibiotic (azithromycin). Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RT-PCR test, acute symptoms, and biochemistry including C-reactive protein (CRP), D-dimer, lactate dehydrogenase, ferritin, and complete blood count were evaluated at baseline and follow-up day seven. Results: Patients who received the CQC adjuvant therapy showed expedited negativization of the SARS-CoV-2 RT-PCR test, i.e., 15 (60.0%) vs. five (20.0%) of the control arm, p = 0.009. COVID-19- associated acute symptoms were rapidly resolved in the CQC arm, i.e., 15 (60.0%) vs. 10 (40.0%) of the control arm, p = 0.154. Patients in the CQC arm experienced a greater fall in serum CRP levels, i.e., from (median (IQR) 34.0 (21.0, 45.0) to 11.0 (5.0, 16.0) mg/dl as compared to the control arm, i.e., from 36.0 (28.0, 47.0) to 22.0 (15.0, 25.0) mg/dl, p = 0.006. The adjuvant therapy of co-supplementation of CQC was safe and well-tolerated by all 25 patients and no treatment-emergent effects, complications, side effects, or serious adverse events were reported. Conclusion: The co-supplementation of CQC may possibly have a therapeutic role in the early stage of COVID-19 infection including speedy negativization of the SARS-CoV-2 RT-PCR test, resolution of acute symptoms, and modulation of the hyperinflammatory response. In combination with routine care, the adjuvant co-supplementation of CQC may possibly help in the speedy recovery from early-stage mild to moderate symptoms of COVID-19. Further research is warranted. Clinical Trial Registration: Clinicaltrials.gov, identifier NCT05130671.

ABSTRACT

OBJECTIVES: To identify the effect of the COVID-19 pandemic on UK herbal medicine practice and how herbal medicine practitioners are supporting people with COVID-19. DESIGN: Mixed-methods e-survey. METHODS: The survey link was distributed through professional associations and social media. Quantitative data were descriptively summarised and qualitative data were analysed using content analysis. RESULTS: Results from 59 responses indicated a profound effect of the pandemic on herbal medicine practice, with a move to remote working and a reduction in client numbers. Practitioners reported prescribing a wide range of medicinal plants, chiefly Glycyrrhiza glabra L. and Echinacea spp. alongside providing information and advice. Few reported inter-professional collaboration. CONCLUSIONS: Herbal practitioners need to build on current collaborations, research and experience to develop consistent approaches to support people with mild-moderate COVID-19 symptoms. More systematic exploration of herbal medicine practice during and as a consequence of the pandemic is needed. WHAT IS ALREADY KNOWN ABOUT THE TOPIC: • The COVID-19 pandemic has had a large impact on all types of healthcare• The impact on herbal medicine practice is unclear. WHAT THIS PAPER ADDS: • The COVID-19 pandemic has substantially affected UK herbal medicine practice• A wide range of medicinal plants are currently used by herbal practitioners to support people with COVID-19• Herbal practitioners need to develop consistent holistic approaches to support people with mild-moderate symptoms of COVID-19.

ABSTRACT

OBJECTIVES: Community pharmacy teams (CPTs) were at the frontline of dealing with patients throughout the COVID-19 pandemic. This study aimed to explore the impact on professional practice and personal well-being of CPTs, in the UK. METHODS: A 25-item survey was designed including a range of open and closed questions. The survey was piloted before being published online via SurveyMonkey and distributed using social media platforms. A combination of opportunity and snowball sampling was employed to recruit participants who worked in community pharmacy (CP) during the pandemic. RESULTS: In total 758 participants (75% completion rate) including pharmacists, owners, managers, technicians, dispensers, healthcare assistants and pre-registration pharmacists took part. Increased workloads and working hours coupled with staff shortages compromised professional practice (n = 257, 35%). Some of the key challenges of working in CP during the pandemic included: a fear of contracting and passing the virus to others (n = 578, 78%), patients stockpiling medicines (n = 530, 71%) and doctors' surgeries being closed (n = 517, 70%) The impact on emotional well-being (n = 433, 76%) included stress, anxiety, depression and loneliness; physically (n = 322, 56%) it affected sleep, pain and weight. The effects of the pandemic left 45% (n = 258/569) of participants reconsidering their future in CP as they felt demotivated, unsupported and undervalued. CONCLUSION: Despite the enhanced pressures and lack of initial recognition CPTs played a vital role in caring for the population during the pandemic. Resources to better support pharmacy teams in the future not only rely on more funding for better provisions but also investing in CPTs' well-being.

ABSTRACT

In times of health crisis, including the current COVID-19 pandemic, the potential benefit of botanical drugs and supplements emerges as a focus of attention, although controversial efficacy claims are rightly a concern. Phytotherapy has an established role in everyday self-care and health care, but, since botanical preparations contain many chemical constituents rather than single compounds, challenges arise in demonstrating efficacy and safety. However, there is ample traditional, empirical, and clinical evidence that botanicals can offer some protection and alleviation of disease symptoms as well as promoting general well-being. Newly emerging viral infections, specifically COVID-19, represent a unique challenge in their novelty and absence of established antiviral treatment or immunization. We discuss here the roles and limitations of phytotherapy in helping to prevent and address viral infections, especially regarding their effects on immune response. Botanicals with a documented immunomodulatory, immunostimulatory, and antiinflammatory effects include adaptogens, Boswellia spp., Curcuma longa, Echinacea spp., Glycyrrhiza spp., medicinal fungi, Pelargonium sidoides, salicylate-yielding herbs, and Sambucus spp. We further provide a clinical perspective on applications and safety of these herbs in prevention, onset, progression, and convalescence from respiratory viral infections.

ABSTRACT

BACKGROUND: Current recommendations for the self-management of SARS-Cov-2 disease (COVID-19) include self-isolation, rest, hydration, and the use of NSAID in case of high fever only. It is expected that many patients will add other symptomatic/adjuvant treatments, such as herbal medicines. AIMS: To provide a benefits/risks assessment of selected herbal medicines traditionally indicated for "respiratory diseases" within the current frame of the COVID-19 pandemic as an adjuvant treatment. METHOD: The plant selection was primarily based on species listed by the WHO and EMA, but some other herbal remedies were considered due to their widespread use in respiratory conditions. Preclinical and clinical data on their efficacy and safety were collected from authoritative sources. The target population were adults with early and mild flu symptoms without underlying conditions. These were evaluated according to a modified PrOACT-URL method with paracetamol, ibuprofen, and codeine as reference drugs. The benefits/risks balance of the treatments was classified as positive, promising, negative, and unknown. RESULTS: A total of 39 herbal medicines were identified as very likely to appeal to the COVID-19 patient. According to our method, the benefits/risks assessment of the herbal medicines was found to be positive in 5 cases (Althaea officinalis, Commiphora molmol, Glycyrrhiza glabra, Hedera helix, and Sambucus nigra), promising in 12 cases (Allium sativum, Andrographis paniculata, Echinacea angustifolia, Echinacea purpurea, Eucalyptus globulus essential oil, Justicia pectoralis, Magnolia officinalis, Mikania glomerata, Pelargonium sidoides, Pimpinella anisum, Salix sp, Zingiber officinale), and unknown for the rest. On the same grounds, only ibuprofen resulted promising, but we could not find compelling evidence to endorse the use of paracetamol and/or codeine. CONCLUSIONS: Our work suggests that several herbal medicines have safety margins superior to those of reference drugs and enough levels of evidence to start a clinical discussion about their potential use as adjuvants in the treatment of early/mild common flu in otherwise healthy adults within the context of COVID-19. While these herbal medicines will not cure or prevent the flu, they may both improve general patient well-being and offer them an opportunity to personalize the therapeutic approaches.
