Qualitative phytochemical analysis of the S.mialhesi extract revealed that it contains natural 
physiologically active substances such as Terpenoids, Flavanoids and phenolic compounds 
[15], and it is already reported that naturally occurring phenolic compounds have 
immunomodulatory activity [16]. 
The present study established that S.mialhesi extract stimulated non specific immune 
response of the animals by increasing the phagocytic activity, measured in terms of 
phagocytic index and this could be attributed to its natural components. 
This stimulation indicates the presence of active principles in the S.mialhesi extract. The 
active principles responsible for the stimulatory effect are yet to be identified.
