Formulation and evaluation of a novel herbal trio gel containing flax seed extract, carbopol and carboxymethyl cellulose.

It is of interest to formulate and evaluate herbal trio gel containing brown flax seed extract, carbopol, and carboxymethyl cellulose and to assess the antimicrobial, anti-inflammatory activity along with quality analysis using SEM and FTIR. The brown flax seeds were grinded into a fine powder and supercritical fluid was prepared which was mixed with CMC and carbopol. The formulation was checked for antimicrobial, anti-inflammatory activity, surface characteristics with SEM and FTIR. The results revealed that the activity of the trio gel was efficacious in hampering the growth of black pigmented anaerobes. The highest zone of inhibition for novel herbal trio gel was recorded at 100 µL measuring 14mm and for the standard chlorhexidine gel it was recorded at 100 µL measuring 23mm in diameter. The results proved that the zone of inhibition of novel herbal trio gel had a decent difference to that of standard chlorhexidine gel. The anti-inflammatory activity showed significant activity at 20 µL which accounted for 53% for the novel herbal trio gel and for the standard diclofenac gel it showed highest activity at 20 µL which accounted for 60%. However, there was not much difference between the herbal trio gel and standard diclofenac gel. SEM observations revealed that the components used in formulation of this trio gel have been bonded well to each other and exhibited appreciable surface characteristics. The lattice of the trio gel has been very well exhibited in SEM analysis. FTIR revealed high peaks showing the different components present in the trio gel. Within the limitations of the study, the results of our study concluded that novel herbal trio gel containing
