The use of plants as traditional medicine against viral diseases in the production of animals have been described and practiced worldwide. Common herbal extracts are used as antiviral agents in treating or preventing virus diseases of farm animals such as poultry, swine, and ruminants. Some of the common viral infections and natural remedies for their treatment are discussed below.
PoultryDisease causing microorganisms in the poultry industry includes various virus, bacteria and protozoa. The most destructive avian viral diseases are Newcastle disease virus (NDV), avian influenza virus (AIV), infectious bursal disease virus (IBDV), infectious bronchitis virus (IBV), egg drop syndrome avian adenovirus, and fowl pox virus.

- Azadirachta indica (neem)Neem, scientifically known as Azadirachta indica, has been shown to demonstrate a wide variety of therapeutic effects including antimicrobial activities. Neem leaf extract significantly reduced the NDV-stimulated splenocyte proliferation in mice to the level comparable to the uninfected control. This suggested that the extract has anti-NDV activity.
- BurttCommiphora swynnertonii (Burtt) has been found to reduce clinical symptoms or severity as well as in antibody titers in the chicken resulting to lower mortality rate. These findings indicate that the resinous extract has strong antiviral activity against NDV in chicken.
