Study Notes

Rasashastra is a vital branch of Ayurveda primarily focused on mercury preparations.
Mercury (Rasa) is a key element in Rasashastra, with "Rasa" translating to "Mercury" or "Parada" in Sanskrit
The fundamental principles of Rasashastra are foundational concepts for mercury preparations, including:
- Dehvada
- Dhatuvada
- Chikistavada
- Shodhana
- Marana
- Satvapatana
- Druti
- Kshetrikaran
- Paribhasha
- Mana (Measurements)

Dehvada explores the belief in attaining immortality through mercury consumption.
"Yadha rasa tatha hyatma yadha hi atma tatha rasa" translates to "As the Rasa (Mercury) is, so is the Atma, and as the Atma is, so is the Rasa".
This concept emphasizes the potential of Rasashastra to influence one’s being, as mentioned in the Rasopanishad.

Lauhavada encompasses the principles of alchemy, a medieval practice primarily focused on transmuting base metals into noble metals.
Alchemy aimed to discover:
- Methods for transmuting base metals into noble metals
- Universal solvents
- The elixir of life.
Rasashastra implements "Astasanskarit Parada" (16 complete sanskaras) to transmute base metals into noble metals.
Historical references support the concept of transmuting base metals into noble metals, which forms a basis for Lauhavada within Rasashastra.

Chikitasavada delves into the therapeutic applications of Rasashastra.
According to Rasa Hridaya Tantram:
- Murchita Parada (purified mercury) alleviates pain.
- Sumruta Parada (highly purified mercury) aids in longevity.
Murchita Parada is used for treating ailments (Vyadhi haranartha).
While it can be used alone, combining Murchita Parada with other minerals enhances its effectiveness.
The potency of Rasashastra preparations leads to high efficacy even in small doses (e.g., Ratti and smaller).

Shodhana translates to "purification" in Sanskrit, referring to the removal of impurities and unsuitable qualities from medicinal compounds.
Shodhana transforms substances physically, chemically, and therapeutically.
Shodhana aims to make substances suitable for further processes or direct therapeutic use.
The choice of media for Shodhana is crucial, considering its specific chemical properties.
Examples of Shodhana media:
- Churnodaka (lime water) for detoxifying Manashila (As2O3)
- Cow's milk and ghrita for purifying Gandhaka.
- Til tail, Gomutra, and kanji for general metal purification, each having a specific pH.
Shodhana methods may include:
- Mardana (trituration)
- Dhalana (melting and quenching)
- Patana (sublimation)
- Nirwapa (heating and quenching)
- Bhavana (levigation)
- Swedana (boiling under liquid bath)
- Prakshalana (washing)
- Bharjana (frying and roasting)
- Nirjalikarana (evaporation of water)
- Prithakkikarana (separation).

Shodhana may be employed to:
- Blend inorganic materials with organic materials for improved absorption.
- Carry out pH-specific reactions for detoxification.
- Target specific body parts based on the materials used (e.g., Bhringaraj swarasa for Gandhaka shodhana to potentiate agni through liver action).
The specific procedures and techniques inherent in Rasashastra are crucial for the preparation of Rasoushadhies (medicinal preparations).
These techniques form the foundational principles of Rasashastra.
The concept of weights and measures (Mana Paribhasha) is another fundamental principle within Rasashastra.
