Antiviral effects of herbal extracts against avian influenza and Newcastle disease viruses

Medicinal herbs have long been used for their ability to manage viral infections and other diseases. Plants are beneficial for treating several bacterial and viral infections in humans and animals. Plants play a crucial role in providing pharmacological and medicinal products due to their capacity to produce chemicals with antiviral properties via secondary metabolism. This could reduce the need for chemotherapy treatments in poultry. Recent research indicates that natural products have a significant promise as a source of novel antiviral agents. Additional ethnobotanical research and laboratory experiments are being conducted to identify plants with the potential to enhance avian influenza virus and Newcastle Disease management. This review sheds light on plants exhibiting antiviral effects against avian influenza virus and 21 Newcastle disease viruses.
