Description
Salem and Lakwani fed rainbow trout an extract of the chaste tree to test its effect on immunity, in a study published in 2025. Fish farms lose stock to disease, and plant additives are a popular alternative to antibiotics. The team kept four groups of trout on equal-energy diets for sixty days. Three diets carried the extract at half, one, or two percent; the fourth was plain. Blood and serum markers of the fishes' first-line immune defenses were measured at weeks four and eight.
The extract raised both burst activity of blood cells and the germ-killing enzyme in serum. Effects grew with dose and time. Stronger built-in immunity could mean fewer outbreaks and less drug use on farms. The authors present the plant as a candidate feed additive, not a cure. Trials against real infections would come next.
