FUTURE OF DEVELOPING THE HERBAL FORMULATIONS:

The drugs obtained from various crude and herbal sources are currently more in use due to their safety and less toxic as compared to synthetic molecules. For the treatment of psoriasis by the use of herbal therapy involve various challenges parameters like, evaluation of anti-proliferative activity of plant, establishment of anti-inflammatory action of crude drugs and development of suitable dosage form containing these herbs. Further it involve the challenge of establishing safety and efficacy of herbal dosage form as compared to synthetic one and to find out the basic mechanism of action of these herbs in the eradication of disease.

However, none has a good benefit/risk ratio ensuring a great efficacy and safety. These above discussed herbal drugs help to contain the disease and relieve the symptoms without healing definitely. Without knowing the key element triggering psoriasis, the attempts to develop a curative therapy seem to doom to failure.
