The anti-stress activity of a gem-containing Unani formulation against diverse stressors.

Drugs of mineral origin, especially gems, are extensively used in Tibb-e-Unani (Unani Medicine), both as single drugs and as compound formulations. But such drugs have not yet been adequately studied scientifically. Jawahir Mohra (JM) is one such, as yet unstudied, anti-stress Unani preparation, containing a few herbal and animal ingredients also. Therefore in the present study, a modified JM preparation was investigated for its anti-stress activity against physical, chemical and metabolic stimuli. The non-gem complement (NGC) of JM was also studied for action against physical stress. In albino rats stressed by swimming and subsequently tested for motor function by Rota rod (muscle coordination), activity wheel (forced motor activity) and photoactometer (spontaneous motor activity), JM treatment for 7 days produced a striking and significant increase in activity. The NGC also increased the activity significantly which was however less than JM. JM also produced a striking increase in cold swimming endurance and in the latency of post-anoxia convulsions, while pentylentetrazol (PTZ)-induced defecation and urination in an open field arena under continuous stimulation by intense light and sound was significantly decreased. Therefore, the present investigation indicates that the gem-containing Unani compound JM has significant anti-stress activity of a non-specific type against diverse stressors. This could be due to adaptogenic activity of the preparation. The study also shows that the gems in JM contribute significantly to its anti-stress activity.
