This 'Systems Ayurveda' graphic notation describes schema of Ayurveda knowledge base. Comprehensive view of concepts and logic is possible through this approach. In addition to logical, sequential linear flow, Ayurvēda also adopts multi-dimensional, one-to-many and many-to-many cause effect relations. We hope the forthcoming poster series on 'Systems yurveda' will illustrate potential and practical applications of logic and vast knowledge base of Ayurvēda. "Systemns yurvēda' is an entity relationship notatior based on Systems Biology Graphical Notation (SBGN) concept '. This first poster broadly describes logical flow forward loops, backward loops, entity relations and their applications in health and diseases. The foundations and logic of Ayurvēda is mainly based on Sankhya anc Vaiśēşika philosophy. According to this, every matter (Padartha) is composed of five primordial elements (Mahäbhūta). The manifested parts of matter are microcosm (the living) and macrocosm (universe); both could be assessed by similar logic and method. Main aim of Ayurveda is to promote health, Iongevity and alleviate diseases. This is achieved through homeostasis of Dõșa, Dhātu, Mala and Agni. Appropriate conduct including proper lifestyle and diet leads to health. Effects of Dravya as diet, drug also as causative factor depends on properties and activities relative to the context. The processing (Samskāra) enables augmentation of healt promoting properties and reducing toxicity of medicines. The disease process initiates from causative factors (Hetu) and any disturbance in organs (e.g. Dhatu). The Samprāpti is process through several steps (Șațkriyākāla) and manifests into disease. The holistic approach of Āyurvēda management aims at establishing health_ through multifarious _ treatment modalities including counselling, avoiding causes Pañcakarma, medicines, diet and surgical procedures Every aspect of Systems Ayurvēda' logic is linked to other components and has specific role in maintenance of health and/or treating diseases. The 'whole to part relation of Ayurvēda philosophy is important for better understanding of comprehensive account. The immense data consisting of near 300 variables describing logical flow and concepts of Ayurveda have been presentec using SBGN approach for processes, entity relationships and activity flow.
