A study to evaluate the preservative action of Twak Arka in Triphala Kwatha

Introduction: Primary dosage forms are basic preparations whose shelf life is a challenge for the practice. Kwatha preparation which easily prone to contamination and can be marketed only by addition of suitable preservatives increase life. So being practiced prolong kwatha but presently using chemical harmful body even have carcinogenic effects. Hence there aroused need find natural preservatives. Arka water distillate consists essential substances from crude drug has longer Twak arka possess anti- microbial oxidant properties economically cheaper available triphala useful in many purposes. In this study an attempt was made elucidate preservative action twak kwatha. Materials methods: Includes arka, conduction analytical microbiological see SDA MHA media. Observations results: Study follows observations over growth sample on daily basis where showed 31 days. Aspergillus niger fungal seen 32nd day. Discussion: owing its pH, constituents other preserved stipulated period time. Conclusion: From study, it concluded that without any days added concentration 15%.
