Ashwagandha (Withania somnifera), also known as “indian ginseng” and “winter cherry”, is a subtropical evergreen shrub belonging to the Solanaceae family which commonly grows in areas of Africa, the East Mediterranean region, Pakistan, and India. The extract or powder from the plant's roots are a popular Ayurvedic herb, used for over 3,000 years to aid in relieving stress, increasing energy levels, and improving concentration.

Ashwagandha is also known for its anti-inflammatory, antibacterial, antifungal, antioxidant, hepatoprotective, immune stimulating, and antitumor properties.

The main chemical components of benefit are the plant's high concentration of withanolides, which are steroidal lactones that have been shown to fight inflammation and tumor growth. More than 40 withanolides, approximately 12 alkaloids, and several sitoindosides have been isolated and identified.

There have been numerous research studies on Ashwagandha in humans, chickens, mice and rats. Some of the key benefits discovered in relation to chickens include:
  • E. coli infection. Ashwagandha root extract reduced the severity, mortality, and recovery period of chickens with E. coli infection, and enhanced their humoral and cellular immune responses.
  • Ovarian cancer. Ashwagandha root powder mixed with their basal ration for 90 days at a dosage of 2 g/kg body weight reduced the incidence and progression of ovarian tumors in hens.
  • Infectious bursal disease (IBD). Ashwagandha alleviated infectious bursal disease virus (IBDV)-induced stress and histological and immunological alterations and reduced IBDV persistence in the host.
