The system of Ayurveda is different from other disciplines of life science due to its holistic approach and systematic documentation. Alike other branches of Ayurveda, rational scientific thoughts are found in its pharmaceutical branch too. Various measures were adopted in classical Ayurvedic pharmacy to concentrate the desired fraction and to arrive at a product with desired characteristics with therapeutic efficacy. Various classical pharmaceutical procedures such as Bhavana (Trituration), Shodhana (Purification), Marana (Incineration), Amritikarana (Notarisation), Satvapatana (Extraction of metal) are adapted to convert the raw metals and minerals into easily absorbable, palatable and quick acting therapeutic form. https://biomedpharmajournal.org/vol2no2/rationality-of-ayurvedic-pharmaceutical-procedures/ Ayurveda Bhavana Shodhana Marana Rationality
