ABSTRACT:

Introduction: The term Rasa Shastra translates to the "Science of Mercury," with Rasa being a synonym for mercury itself. This specialized branch of Ayurveda primarily deals with the processing and therapeutic application of substances derived from metals, minerals, and herbo-mineral origins. It encompasses a wide array of substances collectively known as Rasa Dravyas, which include Rasa (mercury), Maharasa, Uparasa, Sadharana Rasa, Dhatu, Upadhatu, Ratna, Upratna, Visha, and Upavisha. Formulations prepared using these ingredients—excluding purely herbal preparations—are classified as Rasaushadhis (herbo-metallic or metallic medicines). These formulations are valued in Ayurveda for their potent therapeutic effects, which include rapid action, minimal dosage requirement, and broad-spectrum efficacy regardless of a person’s constitution (Prakriti). Besides treating ailments, Rasaushadhis are also recognized for their Rasayana (rejuvenative) properties, contributing to delayed aging, enhanced vitality, improved immunity, and strengthened body tissues. Materials and Methods: A range of classical Ayurvedic texts and contemporary scholarly resources were consulted to compile information related to Rasaushadhis. This study aims to highlight the significance of Rasa Shastra as a distinct Ayurvedic discipline, its historical development, and categorization of Rasa Dravyas including Rasa, Uparasa, Maharasa, Sadharana Rasa, Dhatu, Upadhatu, Ratna, Upratna, Visha, and Upavisha. The classification of Rasaushadhis into mercurial and non-mercurial groups is discussed, with particular focus on the role of mercury and its compounds like mercuric sulphide. The paper also outlines the potential toxicity risks of improperly prepared Rasaushadhis, essential precautions during administration, and emphasizes the necessity of purification (Shodhana) and proper pharmaceutical processing. Additionally, both traditional Ayurvedic and modern scientific analytical techniques—such as organoleptic evaluation, physicochemical testing, and advanced instrumentation—are briefly reviewed to ensure the safety and efficacy of these formulations. Conclusion: Rasaushadhis exhibit significant therapeutic benefits across a broad range of health conditions. They are widely appreciated for their rapid onset of action, low dosage, palatability, ease of administration, and extended shelf life. However, their safe and effective use hinges on meticulous preparation involving proper purification and processing, alongside thorough evaluation through classical and modern analytical methods. Adherence to appropriate dosage, timing, dietary restrictions (Pathya), and contraindications (Apathya) is crucial to harness their full therapeutic potential while avoiding adverse effects.

INTRODUCTION:

Ayurveda holds that every substance in the universe can serve as medicine if used appropriately by a skilled physician1. Ayurvedic pharmaceutics incorporates drugs not only from plant sources (Audbhida) but also from animals (Jangama) and minerals/metals (Parthiva or Khanija), including materials like gold, silver, copper, and sulfur.2,3

 

Rasa Shastra, literally meaning "Science of Mercury," is a specialized branch of Ayurveda focusing on herbo-mineral, metallic, and mineral-based formulations known as Rasaushadhis. These medicines are renowned for their rapid action, minimal dosage, and wide-ranging efficacy across constitutional types.4 In addition to their therapeutic roles, they also act as Rasayana—promoting longevity, strength, and immunity.

 

The evolution of Rasa Shastra is attributed to the legendary sage Nagarjuna, revered as the father of this science. His vision extended beyond alchemy (Dhatuvada) to include spiritual and physical transformation (Dehavada)5, using mercury to eliminate suffering and poverty. With his contributions, Rasa Shastra emerged formally around the 8th century with systematic documentation.

 

 

Initially, metal-based preparations were limited to simple powdered forms, but with time, advanced methods like Shodhana (purification) and Marana (incineration) led to the development of Bhasma — refined, detoxified metal powders used safely in therapy. These processes were scientifically designed to eliminate toxicity and enhance bioavailability.

 

Classical Quality Tests for Bhasma: 6

Rekha Purnatwa: Fineness confirmed when Bhasma settles in the finger ridges.

Varitaratwa: Floats on water, indicating lightness and fineness.

Apunarbhava: Does not revert to its original metal form upon heating with specific agents.

Nirutthatva: No weight change in silver when heated with Bhasma, confirming complete incineration.

 

Modern Analytical Parameters:7

XRD (X-ray Diffraction): Qualitative analysis of crystal structure.

SEM (Scanning Electron Microscopy): Surface morphology.

PSD (Particle Size Distribution): Confirms fineness.

ICP (Inductively Coupled Plasma Spectrometry): Elemental composition.

If a Bhasma fails any of these tests, it may retain toxicity and should not be used therapeutically. Thus, rigorous traditional and modern validation ensures safety and efficacy in Rasaushadhi formulations.

 

RASA AUSHADHI:

Rasa Shastra incorporates not only Rasa, but also Maharasa, Uparasa, and Sadarana Rasa, Dhatu, Updhatu, Ratan, Upratan, Visha & Upvisha etc. called as “Rasa Dravyas”. Hence the Metallic, Mineral or herbo-mineral formulation (not poly- herbal) which consist above Rasa dravyas as one of its constituents can be termed as Rasaushadhi.8

IMPORTANCE OF RASA AUSHADHIS:

According to Rasa Sara Samgraha:

·      Very quick in action.

·      Quick Assimilation (The assimilation of Rasa preparations in the body is much faster because the preparation undergoes different processes called “Samskaras”.)9

·      Small dose is required as compared to herbal dose.

·      Easy to take, so patient’s acceptability is more.

·      Long shelf life and easy preservation as compared to herbal medicines.

·      More therapeutic efficacy as compared to herbal drugs. Acc. to Rasa Sara Samgraha one can treat Sadya types of diseases by using any type of medicine, but in case of Asadya Rogas, Rasaushadhis are best choice.10

 

According to Rasapaddati:

Three types of Treatment:

1.     Daivi –Treatment which carried out with Rasa Dravyas.

2.     Manushi- Treatment carried out with Churna, Sneha, Kashaya, and Lehyas.

3.     Asuri –Treatment carried out with Sastras.

4.     Using the term “Daivi” emphasizes the superiority of Rasa Aushadhis over other herbal formulations.

 

Role of Rasa Aushadhis as Rasayana:

In Rasa Shastra, numerous formulations are recognized for their Rasayana (rejuvenative) properties. While several such compounds are directly mentioned in Rasayanadhikara, many more are described across other chapters, functioning primarily as Rasayana but indicated for specific diseases. These formulations often include ingredients known to promote longevity, vitality, and systemic balance.

 

Parada (mercury) is regarded as one of the most potent Rasayana substances. When thoroughly purified and processed, it helps balance the Tridoshas, delays aging, prevents disease onset, and revitalizes vital organs. When combined with appropriate herbs, its therapeutic potential is significantly enhanced.

 

In addition to mercury, several other metals and minerals such as Swarna (gold), Rajata (silver), and Shilajatu (mineral pitch) are also highlighted in Rasa Shastra for their rejuvenating effects. Rasayana therapy, as a whole, supports longevity, boosts immunity, enhances cognitive functions like memory and intelligence, improves complexion and vitality, nourishes body tissues, regulates metabolism, and strengthens both body and mind, thereby sustaining overall physiological harmony.

 

CLASSIFICATION OF RASA AUSHADHIS:

Although Rasaushadhis are named after Parada (mercury), they are broadly classified into two categories: Mercurial and Non-mercurial formulations. The introduction of mercury into therapeutics marked a turning point in Ayurvedic medicine, initially being used not as a primary drug but as a bio-enhancer. When combined with other substances, mercury was believed to significantly enhance efficacy while reducing the required dosage.

 

Before its medicinal use, mercury undergoes a rigorous purification process (Shodhana) to become Shuddha Parada (purified mercury). It is then further processed into stable, non-toxic, and therapeutically potent forms known as Baddha or Murcchita Parada.

 

A foundational component in many mercurial preparations is Kajjali, a black, smooth, and fine powder formed by thoroughly triturating purified mercury with sulphur. Named for its resemblance to collyrium (kajal) in both appearance and texture, Kajjali serves as the base for numerous mercury-based formulations in Rasa Shastra.

 

MERCURIAL RASAUSHADIS:

Based on the method of preparation, the mercury-based drugs are classified as 1. Khalvi rasa, 2. Parpati rasa 3. Kupipakwa rasa and 4. Pottali rasa.

·       Khalvi Rasa: This type of formulation involves thorough trituration of mercury, sulphur, and other prescribed herbal, mineral, or metallic ingredients using a mortar and pestle. Since the grinding process is carried out in a mortar called Khalva in Ayurvedic terminology, such preparations are referred to as Khalvi Rasa. The outcome is a fine, homogenous medicinal powder.

 

·       Parpati Rasa: In this method, purified mercury and sulphur are first ground together, often with the addition of specific metal Bhasma, to produce Kajjali—a soft, black, homogenous powder. This mixture is then gently heated in an iron spatula until it melts. The molten mass is quickly poured onto a soft, even surface, typically a banana leaf placed over a moist platform made from mud or fresh cow dung. Another banana leaf is immediately placed on top, and the mass is flattened by pressing it uniformly by hand. After removing the top leaf, the thin, flat, sheet-like product obtained is known as Parpati.

 

·       Kupipakva Rasa: This preparation involves heating Kajjali (a mixture of mercury, sulphur, and other ingredients) in a sealed glass flask with a long, narrow neck, known as a Kupi. Sometimes, earthenware or metal crucibles may also be used. Controlled heating is employed to transform the ingredients into stable compounds. The final product of this method is termed Kupipakva Rasa, widely used in various chronic conditions due to its potency and long shelf life.

 

·       Pottali Rasa: In this method, the prepared Kajjali is wrapped tightly in a silk cloth to form a bundle called a Pottali. Separately, sulphur is melted in a wide-mouthed vessel to create a sulphur bath. The Pottali is then immersed in the molten sulphur and subjected to high-intensity heating. During this process, the Kajjali hardens into a solid ball, forming the final product known as Pottali Rasa. The burnt silk cloth sticking to the surface is carefully scraped off. When needed, the ball is rubbed on a moist stone slab in circular motion to generate a paste, which is administered to the patient in small, precisely measured doses. This formulation is known for its rapid action and is often used in emergency or acute medical conditions.

NON-MERCURIAL RASA AUSHADIS:

1.     Bhasma:

Minerals and metals other than mercury are also subjected to Shodhana and Marana processes. In the process of Shodhana’, the material is subjected to grinding in a prescribed liquid media or heated and quenched or bathed in a suitable hot liquid media like cow milk, butter milk, cow urine, sesame oil or decoction or extracted juice of specified medicinal plant. The material is sometimes kept soaked overnight or boiled in liquid media for a prescribed period. Whereas sometimes the material is cooked in cow milk, sour vinegar or lime water.

 

In the process of Marana therapeutically purified material is subjected to grinding with prescribed medicinal plant decoctions, juices etc., followed by incineration of ground material in a closed earthenware container to obtain fine and soft calcined product called Bhasma’.

 

Some of the minerals such as Sulphur, Hematite, Alum, Borax etc. do not require incineration as they are very soft and palatable in their natural form. They are simply subjected to therapeutic purification i.e. Shodhana for removing impurity and toxicity. Sometimes the Bhasma’, although prepared carefully cannot get rid of properties or ingredients which prove harmful and toxic to the body. In such circumstances the Bhasma is subjected to further processing. These procedures are termed as Amritikarana and Lohitikarana’. This is generally practiced in case of Abhraka Bhasma (Bhasma prepared from Mica). In Amritikarana the Abhraka Bhasma is cooked with ghee and decoction of Triphalaa’. In Lohitikarana the Abhraka Bhasma is once again subjected to incineration with the prescribed medicinal plants.

 

2.     Pisti:

Pisti is prepared from minerals of gem quality. The purified minerals are subjected to wet grinding with prescribed liquids till a fine, dry powder is obtained.

 

3.     Satva:

Satva is prepared by subjecting the source material to intensive heating with borax at very high temperature.11

DISCUSSION:

In Ayurveda, the potential of a drug to act either as a remedy or a toxin lies in its proper preparation and administration. A well-processed and appropriately used formulation can act as a panacea, while one that is poorly prepared or wrongly administered can turn poisonous. This is particularly true for Rasaushadhis—herbo-mineral and metallic formulations—which require meticulous attention at every stage, from selection and processing of raw materials to patient-specific administration.

 

Proper dosage is crucial in the administration of Rasaushadhi. If taken in insufficient quantities (Alpamatra), the drug may not show the desired effect, whereas an excessive dose (Atimatra) may lead to adverse reactions or toxicity. The time, frequency, and duration of administration must also align with the guidelines mentioned in classical texts to ensure optimal efficacy. Each Rasaushadhi is advised to be taken with a specific Anupana (vehicle) like milk, ghee, or honey, which aids in the absorption, assimilation, and safety of the medicine. Ignoring dietary and lifestyle recommendations (Pathya-Apathya) during or after treatment can result in therapeutic failure or adverse outcomes. Moreover, while mineral-based drugs are often believed to have long shelf lives, herbo-mineral formulations may degrade, so checking the expiry is essential before administration.

 

Ensuring the identity, quality, and standardization of raw materials, as per the guidelines of the Ayurvedic Pharmacopoeia of India (API) and the Ayurvedic Formulary of India (AFI), is another vital step. The patient’s Prakriti (constitution)—Vataja, Pittaja, Kaphaja, Dvandvaja, or Tridoshaja—must be assessed before prescribing any medicine, as drugs with similar properties (Guna) can aggravate the dosha, while those with opposing qualities can help balance it. Therefore, the physician’s diagnostic skills and clinical judgment (Yukti) are indispensable for the safe and effective use of Rasaushadhis.

When these essential principles are neglected, Rasaushadhis can become toxic. For instance, improperly purified mercury (Parada) may cause severe conditions such as fever (Santapa), unconsciousness (Moorcha), stiffness (Jadata), and skin diseases (Kushta), and can even be fatal. Modern toxicology supports these findings, associating impure mercury with skin disorders, digestive disturbances, reduced immunity, vomiting, and other systemic issues. Other improperly processed ingredients such as Vaikranta (Tourmaline), Swarna Makshika (Pyrite), and Gandhaka (Sulphur) may cause a range of conditions from eye disorders, indigestion, and skin diseases to anemia, dizziness, infertility, and general debility.

 

Mercury plays a central role in Rasa Shastra, which is evident from the fact that the entire discipline is named after it. Its unique chemical and pharmaceutical properties have been harnessed to enhance the effectiveness of formulations. A standout quality of mercury is its Yogavahitva—its catalytic ability to potentiate the therapeutic effects of substances it is combined with, while retaining its own properties. This enhances drug bioavailability, shortens the onset time of action, and reduces the dosage needed for effective therapy. The term Rasibhavana refers to the process through which metals, once converted into Bhasma, acquire mercury-like qualities—becoming more assimilable and effective.

 

The quality of Bhasmas depends significantly on the substances used during their preparation. Bhasmas prepared using mercury are considered the most potent, those prepared with plant materials are of moderate quality, and those processed with sulphur are considered less effective. If antagonistic metals (Ari-Loha) are used, the resulting Bhasma may even be harmful. This hierarchy underscores the importance of mercury in producing high-quality, therapeutically valuable Bhasmas.

 

Despite its known toxicity in raw form, mercury is safely used in Ayurveda as mercuric sulphide (HgS)—commonly called Kajjali. This inorganic compound is significantly less toxic than organic forms such as methyl mercury, which are thousands of times more harmful. Inorganic sulphide compounds like Kajjali are poorly absorbed in the gastrointestinal tract, making them relatively safe. Mercury is also detoxified through classical Ayurvedic methods like grinding, boiling, heating, and distillation using agents such as Rasona (garlic) and Kanji (fermented gruel), most of which contain sulphur. This sulphur not only helps neutralize mercury’s toxicity but also contributes essential nutrients to the body.

Sulphur plays a vital role in human biochemistry, being a component of important biomolecules like glutathione, methionine, cysteine, and taurine, which support antioxidant functions and cellular defense mechanisms. Medicines containing Kajjali may promote the formation of these compounds, thereby aiding in tissue regeneration and slowing the aging process. Mercury also functions as a transient catalyst for antioxidant activity, supporting rejuvenation at the cellular level.

 

An additional advantage of mercury-based formulations is their controlled drug release. Herbal powders triturated with Kajjali exhibit a structured layering, alternating between active herbal ingredients and inert mercury sulphide. This design allows for a timed and sustained release of the medicine in the gastrointestinal tract. As a result, the drug is gradually absorbed and released in response to the body’s requirements. When the plasma concentration of the active component falls, the body’s biofeedback mechanisms may trigger the release of more drug, thereby ensuring continuous therapeutic action over a longer period.13

 

Rasaushadhis—when carefully processed, appropriately prescribed, and judiciously administered—offer significant therapeutic benefits. Mercury, with its unique properties and proper handling, plays a crucial role as a bio-enhancer and pharmaceutical agent in Ayurvedic medicine. However, adherence to classical guidelines and modern safety protocols is essential to ensure their efficacy and avoid potential toxicity.

 

CONCLUSION:

Rasaushadhis possess broad-spectrum therapeutic potential and are effective in managing disorders across nearly all systems of the human body. Their widespread use can be attributed to several advantages, including rapid onset of action, minimal required dosage, better palatability, convenient administration, and extended shelf life. However, to ensure their safety and efficacy, these formulations must undergo meticulous processing and purification, following both traditional Ayurvedic methods and modern analytical techniques. Additionally, critical factors such as accurate dosage, appropriate duration and timing of administration, as well as adherence to Pathya (recommended lifestyle and diet) and avoidance of Apathya (harmful practices or substances), must be carefully observed. These precautions are essential not only to avoid adverse effects but also to optimize the therapeutic benefits of Rasaushadhis.
