Introduction

Siddha therapeutics is organized into 64 treatment modalities: 32 internal medicines and 32 external therapies. This systematic classification, found in the classical text Agastya Vaithiya Rathinam, provides a complete framework for treating every known disease. For the student, the 64 modalities represent a comprehensive pharmacopoeia that must be learned in detail over years of study. For the patient, the wide range of treatment options means that therapy can be tailored to individual constitution, disease severity, and personal preference. For the clinician, the 64 modalities offer multiple therapeutic entry points for each condition — if one approach fails or produces side effects, another can be selected without abandoning the overall treatment plan.

ⓘ Information

Siddha treatment selection follows specific rules. For acute conditions, liquid dosage forms (Kudineer, Saaru) are preferred because they are rapidly absorbed. For chronic conditions, solid dosage forms (Chooranam, Lehium, Mezhugu) are used for sustained therapeutic effect. For children and the elderly, mild dosage forms are selected with reduced potency. The route of administration is also determined by the condition: oral for systemic disease, topical for skin and joint conditions, nasal for head and respiratory conditions, and rectal for Vatha disorders of the lower body. The clinician selects not only the correct medicine but also the correct dosage form, dose, time of administration, and vehicle (anupanam).

The 32 Internal Medicines (Agamarunthukal)

The internal medicines are divided into four groups of eight, each group representing a different dosage form. Chooranam (powders) are finely powdered herbal, mineral, or herbo-mineral formulations, typically taken with honey, ghee, or warm water. The standard dose is 1 to 3 grams. There are 32 types of Chooranam described in classical texts, varying by the number of ingredients (single herb to complex formulations of 30 or more ingredients). Examples include Thirikadugu Choornam (three pungent herbs — ginger, black pepper, long pepper) for digestive disorders and Amukkara Choornam (Withania somnifera) for vitality and Vatha disorders.

Kudineer (decoctions) are water extracts of herbs prepared by boiling coarse powders in water until reduced to one-fourth or one-eighth of the original volume. They are the fastest-acting internal medicine and are used for acute conditions including fevers, respiratory infections, and inflammatory disorders. Well-known examples include Kaba Sura Kudineer for fevers and respiratory infections — a formulation that gained scientific attention during the COVID-19 pandemic for its immunomodulatory properties — and Nilavembu Kudineer for dengue fever, which has been the subject of clinical research published in peer-reviewed journals.

Lehium (medicated jams or confections) are semi-solid preparations made by cooking herbal powders in sugar, honey, honey, or ghee. They are palatable, have a longer shelf life than other dosage forms, and are suitable for chronic conditions requiring sustained therapy. Lehium formulations often include nervine tonics, aphrodisiacs, and rejuvenatives. The dose of Lehium is typically 5 to 10 grams.

Mezhugu (waxes or waxy preparations) are solid or semi-solid formulations made with ghee, oil, wax, or resin as the base. They contain potent ingredients, often mineral or metallic, and are used in small doses (130 mg to 500 mg) for chronic, deep-seated diseases. Thalanga Mezhugu is a classic example used externally for skin diseases — it contains marking nut, copper sulfate, and other ingredients that must be prepared and applied by a trained practitioner only.

★ Key Concept

The classical texts describe eight forms of each medicine group. For Chooranam: (1) single herb powder, (2) compound powder, (3) roasted and powdered herbs, (4) powdered herbs processed in decoction, (5) powdered herbs processed in juice, (6) powdered herbs processed in milk, (7) powder processed in ghee, and (8) powder processed in honey. The same eightfold classification applies to Kudineer, Lehium, and Mezhugu — each successive form having greater potency and requiring more preparation skill. This graduated approach allows the clinician to match the strength of the medicine to the severity of the disease.

The 32 External Treatments (Puramarunthukal)

External therapies in Siddha are just as systematic as internal medicines. The five forms of Patru (poultices) use herbal pastes applied externally for inflammation, swelling, pain, and skin conditions. Poultices are categorized by application temperature: cold poultices for Pitha conditions (inflammation, burns, skin rashes), hot poultices for Vatha conditions (joint pain, muscle stiffness, abscesses), and warm poultices for mixed conditions. The five forms of Pugai (fumigation) use smoke from medicinal herbs applied to the body, to wounds, or to the environment. Fumigation with specific herbs is used for skin conditions, respiratory infections, and to purify the air during epidemics.

Thailam (medicated oils) and Ennai (medicated oils for specific purposes) constitute ten of the 32 external treatments. These are oils medicated by heating with herbal decoctions or pastes until the active principles transfer to the oil base. They are used for massage (external application), for nasal drops, for ear drops, and for medicated enemas. Sesame oil is the most common base, though coconut oil, castor oil, and neem oil are also used depending on the condition. Specific oils are formulated for specific humoral imbalances: Mahanarayana Thailam for Vatha disorders, Pinda Thailam for inflammatory joint conditions, and Neem oil for Kapa skin conditions.

⚠ Clinical Correlation

For chronic musculoskeletal conditions such as rheumatoid arthritis (described as Vatha Soriasis in Siddha texts), external therapy is often more important than internal medication. A typical protocol includes daily application of medicated oil followed by fomentation (heat therapy using a herbal poultice or hot compress), weekly Pugai (fumigation of the affected joints with herbal smoke), and periodic Kizhi (herbal poultice massage in which heated poultices of herbal powders, rice, and lemon are tied in cloth bundles and pressed over the joints). This combination of external therapies provides relief that is often superior to internal medication alone for chronic Vatha disorders.

Special Siddha Practices

Varmam (vital point therapy) is a unique Siddha practice in which specific points on the body are stimulated by pressure, massage, or needling to influence physiological function. The classical texts describe 108 Varmam points distributed throughout the body, each with a specific therapeutic application. Varmam points correspond roughly to the marmas of Ayurveda and the acupoints of traditional Chinese medicine, but the Siddha system has its own distinct mapping, stimulation techniques, and clinical applications. Varmam therapy is used for neurological conditions, pain management, musculoskeletal disorders, trauma care, and as first aid in emergencies. It is considered one of the most advanced Siddha skills and requires specialized training.

Ottradam (bone setting) is the traditional Siddha approach to fractures, dislocations, and musculoskeletal injuries. Unlike modern orthopedic approaches that emphasize surgical fixation and immobilization, Ottradam uses gentle manipulation, herbal splints, medicated bandages, and external applications to realign and heal fractured bones. The bone setter (Ottradam expert) uses coconut fiber and bamboo splints for immobilization, and applies specific herbal pastes that are believed to accelerate bone union. This practice continues in some rural areas of Tamil Nadu and is sometimes integrated with modern orthopedics in Siddha hospitals.

Kizhi (herbal poultice therapy) involves the application of cloth bundles containing herbs, rice, sand, or medicinal powders that have been heated and dipped in medicated liquids. The bundles are pressed over the body in a specific sequence. Kizhi is particularly effective for Vatha disorders, joint stiffness, neurological conditions, and post-stroke rehabilitation. Podi Kizhi uses herbal powders heated with oil, Pathra Kizhi (leaf poultice) uses specific leaves heated on a griddle, and Naranga Kizhi uses lemons cut in half and heated.

The Endoverse Concept

The Siddha concept of “endoverse medicine” holds that the human body contains within it all the elements, forces, and principles that exist in the external universe. Every herb, mineral, and metal found in nature has a corresponding site of action in the body. The five elements exist in the body as the five tissues, the three humors correspond to the three cosmic forces (creation, preservation, dissolution), and the seven body constituents correspond to the seven layers of existence. This is not a poetic metaphor but a practical clinical principle — the Siddha clinician selects medicines based on the correspondence between the substance in nature and the disorder in the body. For example, gold (which is heavy, stable, and shining) is processed into Chenduram for conditions requiring strength, stability, and vitality. Mercury (which is fluid, transformative, and mobile) is processed for Vatha disorders. The endoverse principle also explains why Siddha uses the five sense organs — sight, sound, touch, taste, and smell — as diagnostic instruments, because the external world and the internal body are governed by the same laws.

⚠ Caution

This article is for educational purposes only. Siddha treatment modalities, particularly those involving mineral and metal preparations (Parpam, Chenduram, Mezhugu) and Varmam therapy, should only be administered by qualified Siddha practitioners registered with the appropriate regulatory body. Do not attempt to prepare or administer Siddha medicines, especially those containing metals or minerals, without proper training and supervision. Always inform your primary care physician about any traditional treatments you are receiving. The safety and efficacy of specific Siddha treatments should be discussed with a qualified practitioner.
