Abstract
Quality assurance of herbal products may be ensured by proper quality control of the herbal ingredients and by means of good manufacturing practice. We have developed a simple scheme for the standardization and authentication of Sulaharan Yoga a poly herbal formulation. Sulaharan Yoga was prepared as per Ayurvedic Formulary of India. In-house and marketed preparation has been standardized on the basis of organoleptic characters, physical characteristics and physico-chemical properties. The set parameters were found to be sufficient to standardize the Sulaharan Yoga and can be used as reference standards for the quality control/ quality assurance study.
