Background: Pramana, or valid means of knowledge, constitutes the epistemological foundation of Ayurveda. The Charak Samhita, Sushruta Samhita, and Ashtanga Hridayam collectively identify four Pramanas: Pratyaksha (direct perception), Anumana (inference), Aptopadesha (authoritative testimony), and Upamana (analogy or comparison). Among these, Upamana Pramana knowledge acquired through comparison - remains underemphasized in Ayurveda education, despite its significant cognitive value. Objective: This review delivers a comprehensive analysis of Upamana Pramana as described in the principal Ayurveda Samhitas. It examines the definition, scope, philosophical foundations, classical examples, distinguishing features from other Pramanas, and the applied relevance of Upamana in Ayurveda diagnosis, pharmacology, and clinical reasoning. Additionally, the review points out practical learning outcomes for students. Engagement with this material is intended to improve students' ability to distinguish Upamana Pramana in examination contexts, strengthen clinical pattern recognition and diagnostic skills, and deepen understanding of Samhita texts. These outcomes support both theoretical mastery and effective application of analogical reasoning in Ayurveda practice. Methods: The review draws upon historic primary sources, including Charak Samhita (Sutrasthana, Vimanasthana), Sushruta Samhita (Sutrasthana), Ashtanga Hridayam (Sutrasthana), and Ashtanga Sangraha. Commentaries by Chakrapanidatta (Ayurveda Dipika), Dalhanacharya (Nibandhasangraha), and Arunadatta (Sarvangasundara) were also consulted. Secondary literature, such as Darshana texts (Nyaya Sutras, Vaisheshika, Mimamsa), was referenced to provide philosophical context. Results: In Ayurveda, Upamana Pramana is defined as the acquisition of knowledge about an unfamiliar object through its resemblance to a known object. Its validity is based on Sadrishya (similarity or resemblance) between the Upamana (standard of comparison) and Upameya (object to be compared). The classical Samhitas utilize Upamana extensively to describe anatomical structures, disease manifestations, Dosha qualities, and drug properties. The Charak Samhita recognizes Upamana as an independent Pramana, distinct from Anumana, while continuing epistemological conformity with the Nyaya philosophical tradition. Conclusion: Upamana Pramana is an indispensable epistemological tool in Ayurveda, facilitating understanding by structured analogy. Its applications cover from basic anatomy education (Sarira Rachana) to clinical diagnosis (Roga Pariksha) and pharmacological description (Dravyaguna). Systematic study of Upamana improves the capacity for analogical reasoning, a skill fundamental to both traditional Ayurveda practice and contemporary clinical reasoning.
Cholelithiasis, correlated with Pittashmari in Ayurveda, is a common hepatobiliary disorder associated with biliary calculi formation. This case study evaluates the effectiveness of a phased Ayurveda management protocol in a 38-year-old female patient presenting with right upper abdominal pain, burning sensation, bloating, and ultrasonography-confirmed gallstones with biliary sludge. The treatment protocol was administered over 12 weeks and included classical formulations such as Hingvashtak Churna, Arogyavardhini Vati, Varunadi Kwatha, Yava Kshara, and Avipattikara Churna, along with dietary and lifestyle modifications based on Nidana Parivarjana principles. Clinical assessment demonstrated progressive improvement in symptoms, with complete resolution of abdominal pain, burning sensation, and bloating by the final follow-up. Agni status normalized, quality of life improved significantly, and no adverse effects or drug interactions were observed during treatment. The findings suggest that classical Ayurveda management may provide a safe and effective non-surgical approach for selected cases of symptomatic cholelithiasis.
Mukhadushika is a skin disorder characterized by the appearance of Pidika over the face and can be correlated clinically with Acne Vulgaris. Acne vulgaris predominantly affects adolescents and young adults and may adversely affect appearance and quality of life. The present study was undertaken to evaluate the efficacy of Vatapatradi Lepa in the management of Mukhadushika with special reference to Acne Vulgaris and to compare its effect with the control treatment. A randomized, open-labelled, controlled clinical study was conducted on 30 patients aged 16–30 years fulfilling the diagnostic criteria of Mukhadushika. The patients were randomly allocated into two groups, with 15 patients in each group. Group A received Vatapatradi Lepa, while Group B received the control treatment. The respective Lepa was applied locally for 30 days. Clinical assessment was performed before treatment, after 30 days of treatment, and during follow-up. Assessment was based on subjective parameters including number of Pidika, area occupied by Pidika, Kandu, Daha, Srava, and Vedana, along with the Global Acne Grading System (GAGS) score. Both groups showed improvement in the clinical features of Mukhadushika after treatment. Group A demonstrated greater overall improvement, with 96.30% improvement compared with 90.75% in Group B. Reduction was observed in the number and severity of acne lesions and associated symptoms. The study concluded that Vatapatradi Lepa is an effective Ayurvedic topical treatment for Mukhadushika with special reference to Acne Vulgaris. Its superior overall therapeutic response suggests that it may be a promising treatment modality for the management of acne vulgaris.
Chronic Liver Disease (CLD), particularly secondary to chronic alcohol consumption, represents a profound global health challenge characterized by progressive hepatocellular necrosis, hyperbilirubinemia, portal hypertension, and secondary hypersplenism leading to thrombocytopenia. In the Ayurvedic paradigm, this advanced pathological state correlates closely with Kamala (jaundice) manifesting as a complication of Madatyaya, wherein vitiated Pitta and Rakta severely afflict the Yakrit. This comprehensive case report details the diagnostic and therapeutic management of a 42-year-old male patient in Hassan, Karnataka, who presented with intense yellowish discoloration of the sclera, recurrent emesis, localized umbilical pain, and generalized physical exhaustion. Initial biochemical profiling revealed severe hepatic decompensation, marked by a total bilirubin of 11.0 mg/dl, elevated transaminases (AST 230 U/L, ALT 82 U/L), an inverted Albumin/Globulin ratio (0.8), and a depressed platelet count (78,000 cells/cu mm). The patient underwent a rigorous Shodhana regimen commencing with Deepana-Pachana, followed by Abhyantara Snehapana using Indukanta Ghrita in escalating doses from 30 ml to 180 ml over five days. A subsequent two-day Visrama Kala included Sarvanga Abhyanga with Bruhat Saidhav Taila and Sarvanga Parisheka with Dashamoola Qwatha. On the final day, Virechana was administered using 40 grams of Avipattikara Churna, honey, and 100 ml of Triphala Kashaya, successfully inducing 20 vegas. Post-treatment evaluations demonstrated a dramatic biochemical and hematological reversal: total bilirubin declined to 4.6 mg/dl, AST normalized to 77 U/L, the A/G ratio recovered to 1.2, and the platelet count rebounded to 1,10,000 cells/cu mm. These findings substantiate the profound efficacy of classical Ayurvedic Virechana in alleviating hepatic congestion, decompressing the portal system, and promoting hepatocellular regeneration.
Introduction: Skin is the largest organ and most visible organ in human body which exudates various physiological functions and it also prevents invading pathogens.[1] Shwitra described in Ayurveda as type of Kshudra Kushtha, which means a white patch occurred by vitiation of Pitta Kapha Pradhana[2], closely resembles vitiligo in modern medicine. Vitiligo is a chronic chronic autoimmune disorder that causes whitish patches of skin to lose pigment or color; these vary in size and can appear anywhere on the body.[3] In India, studies indicate a prevalence of childhood vitiligo ranging from 23.3% to 26% of all vitiligo cases.[4] While vitiligo can affect individuals of any age, it is more common in children and adolescents. It is necessary to treat the disease by using a therapy which has less side effects and can cure the disease from its root cause in less time period. So Ayurvedic and Modern treatment protocol was followed with diet plan. Drastic results are observed by combination protocol. Methods: In the present case study, a 14 years old female child brought by her parents to Balrog OPD having complaints of whitish patch over right knee in the last 6 months. By examining the patient, the signs and symptoms was diagnosed as Shwitra (vitiligo). Result: Re-pigmentation was observed over 1 month, showing the potential of combined management in Shwitra. Discussion: Classical Shaman, Shodhan Chikitsa is very effective in the root recovery and re-pigmenentation of Shwitra.
