One would wonder why so many ingredients are present in one Siddha/ Ayurveda formulations. What kind of drug-drug interaction happens, is the pharmacological action of the ingredients add up for a better efficacy or are they added to neutralize the undesired effects of certain essential ingredients. Does the combinations made to address multiple problems that co-exist. What is the rationale behind the level of incorporation of each ingredient. In order to address all this questions CTMR decided to have a seminar on the topic 'Admirable ISM drugs and Formulations' on 25th May 2012 at Madras Christian College. About 100 ISM physicians are expected to participate in the Workshop. The Lead speaker will be Vaidya. S.Usman Ali -, with over 50 years in the field of ISM pharmacognosy, pharmaceutics and ISM pharmacology.
