Rasa Shastra Workshop

This workshop introduces the concepts of alchemical medicines and how they align with the science of Ayurveda (Traditional Indian healing system). Why use rasa medicines and what are their advantages and disadvantages over other alternatives.


The potency, stability and specificity of rasa medicines (they tend to be potent and fast-acting) make them an attractive alternative to other medicine. They have a greatly extended shelf-life (in some cases almost indefinite) and finally are recommended for specific conditions where their actions are known to be highly effective in targeting certain physical systems/pathways in the body ie: the water metabolism system and its derangements such as diabetes etc.

Generally, rasa materials can be broken down into four categories; these are: minerals, metals, gemstones and plants. Of these metals are the most complicated to process and reduce to fine oxidised powders, they require intense heating and protracted procedures, slowly integrating them with other materials such as plant juices and other previously prepared minerals.

Often the simplest and most easily converted materials are animal products such as deer horns, pearls, various types of shells and some plant extracts or seeds. Many can be prepared as simple ingredients in a number of days, in some cases even hours.
