Dashamoolarishtam Lehyam: Classical Ayurvedic Lehyam Formulation
Overview
Dashamoolarishtam Lehyam is a classical polyherbal formulation in Ayurvedic tradition, combining Dasha Moola (ten roots) with supporting herbs into a semi-solid medicinal paste or electuary. This article is for educational purposes only and does not constitute medical advice. Please consult with a qualified healthcare practitioner before using this formulation.
Dashamoolarishtam Lehyam is studied in Ayurvedic practice for its integration of multiple botanical components into a single preparation. The term Lehyam (also spelled Lehya) refers to a preparation category traditionally consumed slowly to allow extended contact with oral tissues. This particular formulation is classified within the broader category of Rasayana [rejuvenative] preparations, as it incorporates ingredients traditionally described in Ayurveda as strengthening to foundational tissues and supporting healthy physiological function according to classical Ayurvedic principles.
Dashamoolarishtam Lehyam combines characteristics of decoction-based preparations (Kashaya Kalpa) with semi-solid vehicles, integrating both traditional preparation methods. In classical Ayurvedic practice, the formulation is traditionally associated with supporting conditions described in Ayurveda as Vata Vyadhi [vitiation of Vata humor], according to traditional Ayurvedic principles related to musculoskeletal and nervous system balance. The inclusion of the ten-root complex reflects a fundamental Ayurvedic principle of traditionally addressing multiple physiological factors, while the addition of Ghrta [clarified butter] and other processing media enhances both palatability and therapeutic penetration.
The historical significance of Dashamoolarishtam Lehyam extends across centuries of Ayurvedic clinical practice, with references appearing in foundational texts and regional formulations subsequently adapted throughout the Ayurvedic world. Its continued use in contemporary Ayurvedic clinics and institutional settings demonstrates the enduring recognition of its role within a comprehensive therapeutic framework according to Ayurvedic tradition.
Classical References and Textual Sources
Dashamoolarishtam Lehyam’s development is rooted in classical Ayurvedic literature spanning over two millennia. The following texts provide foundational references for this formulation:
The textual foundations of Dashamoolarishtam Lehyam are distributed across several layers of classical Ayurvedic literature, beginning with the primordial enumeration of Dasha Moola itself in the Charaka Samhita. In the Charaka Samhita, Sutra Sthana, Chapter 4, verse 13, the ten roots are initially classified: Bilva (Aegle marmelos), Shyonaka (Oroxylum indicum), Patala (Stereospermum suaveolens), Gambeeri (Gmelina arborea), Shalaparni (Desmodium gangeticum), Prishniparni (Uraria picta), Brihati (Solanum virgatum), Kantakari (Solanum xanthocarpum), Eranda (Ricinus communis), and Jivaka (Microstylis wallichii). These ten roots are explicitly described as Vatahara [pacifying to Vata], establishing their fundamental therapeutic orientation.
The Ashtanga Hridayam, compiled by Vagbhata in approximately the 7th century CE, provides comprehensive discussion of Dasha Moola preparations in its Uttara Tantra (latter section), emphasizing their application in conditions characterized by Vata Vriddhi [Vata aggravation]. The text describes the preparation methodology for Dasha Moola-based formulations, detailing the traditional ratios and sequential processing steps that form the foundation for Lehyam preparation.
The Sahasrayogam, a medieval Ayurvedic pharmaceutical text attributed to Vagbhata (differing from the classical Vagbhata), contains explicit formulations of Dashamoolarishtam with detailed ingredient specifications and preparation instructions. This text is particularly valuable for understanding regional variations and the evolution of the formulation across different Ayurvedic schools. Specific reference to the semi-solid Lehyam form appears in Chapter 3, where processing with Ghrta, honey, and herbal decoctions is detailed.
The Sharangadhara Samhita, compiled by Sharangadhara in the 13th century CE, provides the most systematic classification of pharmaceutical preparations and their preparation ratios. While not specifically naming Dashamoolarishtam Lehyam, the Madhyama Khanda (middle section) of this text, particularly Chapter 2, establishes the foundational principles for Lehyam preparation that are directly applicable to this formulation. The classical ratio of one part Kalka [herbal paste] to one part Sneha [oil or fat vehicle], combined with proportional Kvatha [decoction], originates from these specifications.
The Bhaishajya Ratnavali, compiled by Govinda Das in the 16th century, presents multiple variations of Dasha Moola formulations adapted into different pharmaceutical forms. This text explicitly describes Dashamoolarishtam Lehyam as a distinct formulation, providing ingredient modifications based on regional availability and seasonal considerations, thus documenting the adaptability of classical formulations within the Ayurvedic tradition.
The Bhava Prakasha, authored by Bhavamishra, provides critical analysis of individual components within Dasha Moola formulations, contributing valuable information regarding the individual Guna [qualities], Rasa [taste], and Virya [potency] of constituent herbs. This text’s emphasis on the synergistic integration of botanical properties is essential for understanding how Dashamoolarishtam Lehyam achieves its traditional therapeutic effects.
The Ayurvedic Formulary of India (AFI), published by the Government of India’s Ministry of AYUSH, documents Dashamoolarishtam Lehyam (Part I, Volume III) as an officially recognized Ayurvedic preparation, with standardized specifications for ingredient ratios, preparation methodology, and quality control parameters. This documentation supports consistency across preparations in accordance with traditional standards.
Composition and Key Ingredients
Dashamoolarishtam Lehyam combines the classical Dasha Moola ten-root complex with additional supporting herbs, all integrated into a semi-solid vehicle. The formulation balances heating and cooling properties while addressing multiple physiological systems according to Ayurvedic principles.
Principal Herb Complex: Dasha Moola

Oil and Fat Vehicles
Ghrita (Clarified Butter, derived from Bos indicus milk): Processed through removal of water and milk solids, leaving pure milk fat. Rasa – predominantly Madhura; Virya – Sheeta; Vipaka – Madhura. In Ayurvedic pharmacology, Ghrita serves multiple functions: as a Sneha Dravya [oleating vehicle] facilitating absorption, as a Yogavahi [synergistic enhancer], and independently as a Rasayana. The classical pharmacological ratio for Lehyam preparation calls for one part Ghrita to one part Kalka [herbal paste] and one part Kvatha [decoction], as specified in the Sharangadhara Samhita.
Honey (Madhu, from bee sources): Rasa – encompasses all six tastes with predominance of Madhura; Virya – Ushna; Vipaka – Madhura. Traditionally considered a Yogavahi [synergistic enhancer] and added in specific proportions during the final stages of preparation. Honey is traditionally added only after cooling to below body temperature, as classical texts describe heating honey as producing potentially undesirable compounds.
Coconut Oil (Narikelataila, from Cocos nucifera): In some regional variations, coconut oil is incorporated as a secondary oleating medium. Rasa – Madhura; Virya – Sheeta; Vipaka – Madhura. This variation particularly reflects southern Indian Ayurvedic traditions where coconut oil predominates in pharmaceutical formulations.
Traditional Preparation Method
Preliminary Processing: Drying and Storage
Classical preparation of Dashamoolarishtam Lehyam begins with the acquisition of quality botanical material. Each of the ten roots should be obtained in dried form, traditionally authenticated by sensory examination—color should be appropriate to the individual herb without discoloration suggesting mold or degradation, fragrance should be characteristic and potent, and texture should demonstrate proper desiccation without brittleness indicating excessive age.
Stage One: Decoction Preparation (Kvatha Nirmana)
The foundational step involves creating a concentrated herbal decoction from the combined Dasha Moola components. Following the methodology described in the Sharangadhara Samhita, Madhyama Khanda, Chapter 2, sections detailing Kvatha preparation:
Each of the ten roots is coarsely powdered or cut into pieces. The classical ratio calls for taking one part of the combined herbal material (by weight) with sixteen parts of water by volume. This combined material is placed in a heavy-bottomed copper or steel vessel and brought to a boil. The preparation is then maintained at a gentle simmer until the liquid is reduced to one-quarter of its original volume—this endpoint is traditionally identified as Pak Paripakva [proper reduction]. At this point, the decoction is strained through multiple layers of fine cloth, yielding the concentrated Kvatha.
This decoction is then allowed to cool to room temperature before proceeding to the next stage. Some classical practitioners recommend dividing the decoction into portions, cooling in earthenware vessels to preserve energetic properties, and storing in a cool location until ready for the subsequent processing stages.
Stage Two: Kalka Preparation (Herbal Paste)
Simultaneously with decoction preparation, the supporting herbal ingredients (Ashvagandha, Shatavari, Vidari Kanda, Bala, and Dhatri Phala) are processed into a fine paste. These herbs are traditionally ground using mortar and pestle or traditional grinding stones, with the addition of small quantities of the freshly prepared decoction to facilitate grinding. The classical Sharangadhara Samhita specifies that this paste, termed Kalka, should achieve a consistency comparable to fresh butter—homogeneous, smooth, and free of visible particulates.
In traditional practice, the grinding of herbs for Kalka is often performed by hand using stone tools, with practitioners believing that this methodology preserves the subtle properties of the herbs that might be compromised by mechanical grinding. However, contemporary preparations employ modern grinding equipment with the understanding that the principle remains: creation of a finely divided, uniform paste.
Stage Three: Pippali and Maricha Integration
The heating spices—Pippali and Maricha—are traditionally processed separately and more minimally than other components. These are usually ground to a fine powder and added directly during the mixing stage rather than being incorporated into the Kalka, as classical texts suggest that minimal processing preserves their volatile and potent properties.
Stage Four: Oil-Based Cooking (Sneha Paka)
The classical procedure now calls for combining the prepared components in a precise sequence, traditionally performed in a heavy-bottomed copper vessel placed over moderate heat. The Sharangadhara Samhita describes three stages of herbal fat cooking, classified as Mrudha Paka [soft/mild cooking], Madhyama Paka [medium cooking], and Khara Paka [hard/intense cooking]. For Lehyam preparation, a moderate cooking approach is employed to avoid excessive heat damage to thermolabile constituents.
The process begins by warming the measured Ghrita (clarified butter) gently. To this warmed Ghrita, the prepared Kalka [herbal paste] is slowly incorporated with continuous stirring, traditionally performed with a wooden spatula. The mixture is maintained at a temperature sufficient to allow gradual cooking and integration but not so high as to produce browning or smoking. Practitioners traditionally monitor this by testing the mixture’s consistency—it should gradually transition from a loose paste to a more cohesive, semi-solid state.
Once the Kalka has been thoroughly integrated with the Ghrita, the concentrated Kvatha [decoction] is slowly added in portions while stirring continuously. This addition should be gradual enough to allow each portion to integrate before the next is added, preventing the formation of lumps. Classical texts recommend maintaining the mixture at a temperature where water from the decoction can gradually evaporate without causing splattering or rapid evaporation that might trap steam pockets.
The cooking continues with regular stirring until the preparation reaches the desired consistency. Traditional practitioners assess doneness through multiple sensory and tactile indicators: the mixture should transition from wet and glistening to increasingly thick and stable; a drop placed on a cool surface should hold its shape without spreading; and the volume should reduce perceptibly from the initial total of combined ingredients. This stage typically requires 45 minutes to 2 hours of gentle cooking, depending on the specific ratios and desired final consistency.
Stage Five: Incorporation of Fine Spices and Secondary Ingredients
After the primary cooking stage has produced the desired thick consistency, the finely powdered Pippali and Maricha are incorporated into the warm preparation with thorough stirring. This relatively late addition preserves the volatile oils and potent properties of these heating spices.
At this point, the sweetening agent—traditionally jaggery (Guda) or, in some formulations, rock sugar—is incorporated. If jaggery is used, it should be finely powdered and added gradually with stirring. The classical ratio calls for approximately one-third to one-half the weight of other solid components as sweetening agent. The inclusion of sweetening serves multiple purposes: enhancement of palatability, provision of shelf-stable preservative effect through osmotic action, and contribution of Brimhana [nourishing] properties.
Stage Six: Final Cooling and Honey Integration
Once the preparation reaches the desired consistency and all ingredients are thoroughly integrated, it is removed from heat and allowed to cool. Classical texts emphasize that honey should never be heated, as traditional pharmacology suggests that heating honey may produce compounds considered therapeutically undesirable. Therefore, honey is typically incorporated only after the entire preparation has cooled to approximately body temperature or below.
The cooling process is traditionally performed in shallow earthenware vessels, with the preparation occasionally stirred to promote even cooling. Some classical practitioners recommend spreading the warm preparation thinly on parchment or cloth during cooling to accelerate the process. Once cooled sufficiently, honey is added in proportions typically ranging from one-tenth to one-fifth of the total final weight, with vigorous stirring to ensure even distribution.
Stage Seven: Maturation and Storage Preparation
Following complete integration, the finished Lehyam is traditionally stored in glass or earthenware containers in a cool location. Many practitioners recommend a 2-4 week maturation period before clinical use, during which the constituent ingredients develop enhanced synergy. Some classical references suggest that the preparation’s properties deepen over the first month of storage, with optimal therapeutic effects achieved after this period.
Indications in Classical Literature
Classical Ayurvedic texts describe Dashamoolarishtam Lehyam as traditionally indicated for conditions characterized by systemic Vata imbalance. The foundational Dasha Moola complex is described in the Charaka Samhita, Sutra Sthana as specifically Vatahara [Vata-pacifying], and this therapeutic orientation structures all clinical applications of the Lehyam formulation.
Vata Vyadhi (Diseases of Vata Vitiation): Classical texts describe Dashamoolarishtam Lehyam as broadly supportive in conditions characterized by excessive Vata—traditionally understood as conditions manifesting pain, dryness, diminished strength, constipation, and related presentations. The Ashtanga Hridayam identifies numerous specific Vata conditions for which Dasha Moola formulations are recommended, and the Lehyam form is considered particularly suitable for cases requiring sustained therapeutic action.
Gridhrasi (Sciatica): Classical texts, including the Charaka Samhita, Chikitsa Sthana, describe conditions characterized by pain radiating along the sciatic nerve and lower extremities. Dashamoolarishtam Lehyam is traditionally employed as a supportive formulation in such presentations, as the Dasha Moola complex is described as specifically addressing pain and functional impairment in the lower body.
Ardita (Facial Nerve Conditions): The Bhava Prakasha and Bhaishajya Ratnavali identify conditions affecting facial symmetry and nerve function as traditionally responsive to Dasha Moola formulations. The inclusion of heating and stimulating herbs is described as addressing the underlying Vata imbalance believed to manifest as such conditions.
Pakshaghata (Paralysis and Hemiparesis): Classical texts describe conditions characterized by unilateral weakness or loss of function. Dashamoolarishtam Lehyam is mentioned in the Sahasrayogam and Bhaishajya Ratnavali as part of comprehensive treatment protocols for such conditions, particularly those described as secondary to Vata imbalance.
Katigrahah (Lumbar Region Stiffness and Pain): The lower back region is classically understood as the primary site of Vata’s manifestation in the physical body. Multiple classical texts identify Dasha Moola formulations as particularly appropriate for conditions of lumbar stiffness, pain, and restricted motion.
Vatarakta (A Condition Combining Vata and Pitta Vitiation): The Bhaishajya Ratnavali and other classical sources describe conditions with mixed Vata and Pitta presentations. While Dashamoolarishtam Lehyam is primarily Vata-focused, formulations incorporating Dasha Moola with cooling supporting herbs are traditionally used in such presentations.
Shula (Pain in General): Beyond specific named conditions, classical texts describe Dashamoolarishtam Lehyam as generally supportive in various pain presentations, particularly those accompanied by diminished strength, constipation, or other indicators of Vata imbalance.
Dhatu Kshaya (Tissue Depletion): The Rasayana herbs incorporated into many formulations of Dashamoolarishtam Lehyam—particularly Ashvagandha, Shatavari, and Bala—are traditionally described as addressing conditions of tissue depletion. The formulation is thus considered appropriate for recovery phases following acute conditions or in chronic conditions accompanied by diminished tissue integrity.
Balakshaya (Loss of Strength): The collective herbs in Dashamoolarishtam Lehyam are traditionally described as Balya [strength-promoting], making the formulation appropriate in conditions of constitutional weakness, recovery from illness, or aging-related strength diminishment.
It is essential to emphasize that all these indications are described in classical Ayurvedic literature as part of a comprehensive understanding of disease mechanisms fundamentally different from contemporary biomedical disease classification. Classical texts frame these conditions through the lens of Dosha [humoral] imbalance, Agni [digestive and metabolic fire] status, and Srotas [tissue channels] vitiation. Contemporary clinical application of these classical preparations occurs within integrated frameworks that maintain respect for traditional theoretical foundations while acknowledging the limitations of direct translation to modern diagnostic categories.
Traditional Methods of Administration
Classical Ayurvedic pharmacology recognizes that therapeutic efficacy depends not only on formulation composition but also on appropriate administration methodology. For Dashamoolarishtam Lehyam, various traditional administration routes are described in classical texts, each suited to specific clinical presentations and treatment goals.
Oral Administration (Mukhapath)
The most common administration route for Lehyam preparations is oral consumption. The Lehyam itself is designed to be slowly licked or consumed by mouth, allowing prolonged contact with oral tissues and gradual absorption. Typical classical dosing for adults ranges from one-half to one full teaspoon (approximately 3-6 grams), consumed once or twice daily. The preparation is traditionally taken in the morning on an empty stomach or in the evening after meals, depending on the specific condition being addressed and the individual’s digestive capacity.
