Since the onset of the current Covid-19 pandemic, the search has been on for methods to provide immunity, decrease mortality and lessen the symptoms of the disease. Much of the current research focuses is on the development of effective vaccines and with good reason. The discovery of an effective vaccine promises the establishment of widespread immunity to the SARS-COV-2 virus and is potentially the best long-term strategy to obtain herd immunity and thereby control this disease. However, the production an effective vaccine may take years and strains of the virus resistant to the vaccine are likely to have developed during that period, lessening the efficacy of the vaccine. Medical science must also look at other options to treat this disease, at least in the interim and potentially as an adjunct to vaccines once developed. Herbal medicines may provide effective therapies with multiple beneficial effects against Covid-19 and these should be explored. Individual medicines may inactivate the virus, block its reproduction or spread, or decrease the symptoms, thereby not only lessening suffering and decreasing mortality, but also lessening further spread. Indeed, several groups have already highlighted the potential of selected herbal medicines against this virus. For example, Thialand Medical News published a report in January 2020 highlighting Glycyrrhiza glabra (liccorice) as a potential therapy for covid-19 based on its previous efficacy against the SARS epidemic of 2003.1 Furthermore, several Chinese studies tested selected Traditional Chinese Medicines (TCM) against covid-19 and reported that some TCMs reduced the symptoms of the disease, especially fevers and decreased the viral load substantially.2 Based on that report, four TCMs were highlighted as having the greatest potential: Qingfei Paidu decoction, Gancaoganjiang decoction, Sheganmahuang decoction and the Qingfei Touxie Fuzheng decoction. Interestingly, liccorice was a major component of all of those therapies, further highlighting its potential as a Covid-19 therapy.

Founded:  In 2004, as the PHCOG.NET – a non-profit private organization dedicated to Natural Products Research leading to develop promising drugs. Our main mission is to make information on herbal drug research readily available in different formats to suit the individual needs.

Pharmacognosy Communications [Phcog Commn.] is a new quarterly journal published by Phcog.Net. It is a peer reviewed journal aiming to publish high quality original research articles, methods, techniques and evaluation reports, critical reviews, short communications, commentaries and editorials of all aspects of medicinal plant research. The journal is aimed at a broad readership, publishing articles on all aspects of pharmacognosy, and related fields. The journal aims to increase understanding of pharmacognosy as well as to direct and foster further research through the dissemination of scientific information by the  publication of manuscripts. The submission of original contributions in all areas of pharmacognosy are welcome.

The journal aims to cater the latest outstanding developments in the field of pharmacognosy and natural products and drug design covering but not limited to the following topics:

  • Pharmacognosy and pharmacognistic investigations
  • Research based ethnopharmacological evaluations
  • Biological evaluation of crude extracts, essential oils and pure isolates
  • Natural product discovery and evaluation
  • Mechanistic studies
  • Method and technique development and evaluation
  • Isolation, identification and structural elucidation of natural products
  • Synthesis and transformation studies

Distinctions:  The most widely read, cited, and known Pharmacognosy Communications and website is well browsed with all the articles published. More than 20,000 readers in nearly every country in the world each month
