Brihattrayi or the three great treatises of Ayurveda are looked up as panacea of Ayurvedic formulations. Out of these, Charak Samhita is considered as foremost in treatment of diseases and their prevention. Almost, 2000 drug formulations are compiled in Charaka Samhita. Still, it encourages and guides an able physician to make modifications and invention of new drugs suitable for the situation. Triphaladi Yoga has been described in Charak Samhita Sutra Sthana Santarpaniya Adhyaya. It is a poly-herbal formulation composed of Amalaki, Haritaki, Bibhitaki, Musta, Aragvadha, Patha, Saptparna, Kutaj, Madanphala & Nimba. The classical reference suggests its use in decoction i.e. Kwatha form. But, for augmenting patient compliance and shelf life; it was converted to tablet form in the present study. Thus, this study makes an effort in preparation and standardization of Triphaladi Yoga tablet as a modified dosage form.
