The study was carried out to investigate the efficacy and safety of seed kernels of Moringa oleifera in the treatment of bronchial asthma.
We have studied the possible mechanism of the antiasthmatic action of Moringa oleifera seed kernel ethanolic extract (EXMO, 400 mg/kg). EXMO produced an increase in the Preconvulsion Dyspnea time induced by histamine and acetylcholine aerosol, a significant reduction in the elevated eosinophil and monocyte counts in the Broncho-Alveolar Lavage fluid of sensitized guinea pigs, reduction in the paw edema volume as compared to the control rats, and decrease in the elevated histamine release from the sensitized guinea pig lungs.
In the present investigation, we studied the effect of alcoholic extract of Moringa oleifera (M. oleifera) seed kernels on various experimental models of bronchial asthma. Significant (P < 0. 05) increase in preconvulsion time was observed due to pretreatment with M. oleifera when the guinea pigs were exposed to either acetylcholine (Ach) or histamine aerosol.
data suggest that M. oleifera and A. aspera possess prophylactic and therapeutic potential for anti-asthmatic activity. None of the patients showed change in any general parameters or any adverse effect suggest safety of drug in dose used. M. oleifera in addition can be used for enhancement in the Hb level.

Moringa can decrease resistance in the respiratory airways and increase airflow to the lungs
