It was seen on the seventh day after five days of in vivo treatment of mice. The most marked immunostimulatory effect was observed on the lysosomal and peroxidal activity of peritoneal macrophages, and splenic cells after in vivo treatment with the ethanolic extract of the roots of R. speciosa Wenderoth.
