The Raktadhatu i.e., the blood is given greater importance in life sciences, especially in the field of surgery. Acharya Susruta has even considered it as an important Dosha as Tridoshas in the etiopathology of diseases, its curative measures and in maintenance of health. To prevent loss of this entity, Acharya Susruta has elaborately described this under a specific heading namely Chaturvidha Rakta Sthambhana Upayas, namely Sandhana, Skandana, Dahana and Pachana. Sandhana is applying Kashayarasa Dravyas in different forms, suturing, ligation, application of pressure and pressure bandages etc. Skandhana is application of cold by any means. Pachana is application of caustic ashes and alkalis. Dahana is to burn by different means. In above methods haemostasis is achieved by inducing vasoconstriction, coagulation, mechanical and physical obliteration of vessels. Thus Skandana, Sandhana, Pachana, Dahana are the absolute haemostatic measures, understanding of which will equip surgeons to face haemorrhage with every available resources.
