Background: Amavata (Rheumatoid Arthritis) is a chronic, progressive inflammatory condition that primarily affects the joints, leading to pain, stiffness, swelling, and restricted mobility. It is characterized by the presence of Ama (undigested toxins) and vitiated Vata Dosha, which together contribute to pathological changes similar to Rheumatoid Arthritis (RA) in modern medicine.

Objective: This study aims to evaluate the effect of Nitya Virechana, assess inflammatory markers (ESR, CRP, ASO, RA factor), and measure the range of joint movements in individuals diagnosed with Amavata/Rheumatoid Arthritis.

Methodology: Nitya Virechana, a subtype of Virechana Karma, is described in classical Ayurvedic texts as a therapeutic intervention that facilitates the elimination of morbid Doshas via the Adhomarga. This procedure is not only beneficial in Pitta Nirharana but also effectively eliminates accumulated Ama, a key pathological factor in Amavata. Classical references suggest Nitya Virechana as an integral component in Amavata management. The present clinical study evaluates the efficacy of Nitya Virechana using Gandharvahastadi Eranda Taila in managing Amavata.

Results: Statistically significant improvement was observed across all parameters, with a p-value < 0.001, indicating positive therapeutic outcomes.

Conclusion: Gandharvahastadi Eranda Taila demonstrated significant efficacy in reducing CRP, RA factor, ASO, along with symptomatic relief and improved joint mobility in Rheumatoid Arthritis. The effectiveness of the treatment has been validated through statistical analysis of key clinical parameters.

Keywords: Amavata, Rheumatoid Arthritis, Nitya Virechana, Gandharvahastadi Eranda Taila

Introduction

Amavata is considered as a both Santharpana and Amaja Vyadhi mentioned by Madhava Nidana which involves Ama along with Tridoshas.[1] The Nidana being mainly Viruddha Ahara and Vihara, which leads to Utpatti of Ama along with Vata Prakopa gets SthanaSamshreya in Kaphasthana resulting in Amavata. The Lakshana’s of Amavata are Angamardha, Aruchi, Trushna, Gourava, Sandhishotha, Sandhishoola, Shoonatanga can be correlated with signs and symptoms of Rheumatoid arthritis.

Rheumatoid Arthritis affects approximately 0.024-1% of the adult population worldwide. Global prevalence rate of Rheumatoid Arthritis with genetic associations in India is 0.7%. It occurs more commonly in females than males, with a 2-3:1 ratio. Annual incidence of Rheumatoid Arthritis is approximately 40 cases per 10,000 and the prevalence rate is of 0.5-1% peaking in age group of 35-60 years. Effective curative management of Rheumatoid Arthritis helps to increase the productivity of individual mostly of the middle age.

Virechana is considered as the best Shodhana to balance the vitiated Dosha. Eranda Taila is mentioned as one of the Snigdha Virechaka Dravya in all Brihatrayees.[3,4] By considering it as best in conditions like Amavata. It has properties like Snigdha, Tikshna, Sukshma Guna, Madhura Vipaka and Ushna Virya. It does both Snigdha and Pachana Karma, Sroto Shodhana that helps to tackle Amavata. Amavata is one among the Shoola Pradhana Vyadhi, mentioned as an independent disease by Acharya Madhavakara. In Madhava Nidana, Acharya has explained regarding the Nidana, Lakshanas.

Acharya Chakradatta,[5] Vangasena,[6] Bhaishajya Ratnakara,[7] mentioned about Langhana, Deepana, Virechana, Katu Tikta Dravya Prayoga in management of Amavata. Acharya Charaka mentioned Eranda as best Agrya for Virechana[2] in Vata Shleshmahara. Acharya Bhavaprakasha and Bhaisheyja Ratnakara[7] mentions Prayoga of Eranda Taila in Amavata. Rheumatoid Arthritis is a chronic inflammatory disorder of autoimmune origin that may affect many tissues and organs but principally attacks the joints producing non suppurative, proliferative and inflammatory synovitis.

First recognized description of Rheumatoid arthritis in modern medicine was in 1800 by the French physician Dr. Augustine Jacob Landre Beauvais.[8]

Discussion

Virechana is considered an essential therapeutic procedure in Ayurveda that promotes the elimination of toxins (Ama) and balances the Doshas. In this study, the use of Nithya Virechana, a daily form of Virechana, showed promising results in the management of Amavata. Eranda Taila, the key ingredient in this procedure, is known for its effectiveness in treating diseases associated with joint inflammation, especially those related to vitiated Vata Dosha. The therapeutic benefits of this treatment were observed in the reduction of joint pain, stiffness, and swelling, which are common symptoms of Amavata.

Amavata, as described in Ayurveda, is a condition characterized by the accumulation of Ama (toxins) in the joints, which causes pain, swelling, and stiffness. These symptoms resemble those of rheumatoid arthritis, a chronic inflammatory disorder. The pathogenesis of Amavata involves interplay of aggravated Vata Dosha and the formation of Ama, which settles in the joints, leading to inflammation and joint dysfunction. This understanding aligns with modern clinical findings of RA, where the body’s immune system attacks its joints, causing systemic inflammation and discomfort. The study’s findings, including reduction in inflammatory markers such as C-Reactive Protein (CRP) and Erythrocyte Sedimentation Rate (ESR), further support the Ayurvedic concept of Amavata as an inflammatory disease.

Eranda Taila, with its potent properties of being Snigdha (unctuous), Tikshna (sharp), and Ushna (hot), is particularly effective in addressing Vata-related disorders. The use of Gandharvahastadi Eranda Taila in Nithya Virechana therapy was observed to reduce the inflammatory markers and alleviate the symptoms associated with Amavata. The anti-inflammatory properties of the oil, in combination with its detoxifying effects, helped in reducing joint swelling, tenderness, and stiffness. This aligns with the Ayurvedic view that such therapies can pacify aggravated Doshas and provide relief from inflammatory conditions.

The study methodology, which included a combination of subjective and objective markers such as Range of Movement (ROM), RA score, and inflammatory markers, proved to be an effective approach for assessing the clinical outcomes of Nithya Virechana. Significant improvements were noted in joint mobility across various joints, including the lumbar spine, cervical spine, wrist joint, and knee joint, confirming the treatment’s efficacy in improving flexibility and reducing pain. Additionally, the decrease in the RA score and inflammatory markers (CRP, ESR) demonstrated a reduction in systemic inflammation, highlighting the systemic benefits of the treatment.

The study shows that Nithya Virechana with Gandharvahastadi Eranda Taila is an effective therapeutic approach for managing Amavata. It significantly improved joint mobility, reduced pain, and decreased inflammatory markers,


aligning with both Ayurvedic principles and modern clinical findings. The reduction in subjective symptoms like Angamarda, Gaurava, and Alasya further underscores the treatment's effectiveness in managing both the local and systemic manifestations of Amavata. Further studies with larger sample sizes and longer follow-up periods are needed to confirm the long-term benefits and to establish Nithya Virechana as a reliable treatment option for chronic inflammatory diseases like Amavata.

Conclusion

Nitya Virechana Karma with Gandharvahastadi Eranda Taila effectively alleviated the symptoms of Amavata by balancing Vata and Kapha Doshas. The therapy demonstrated significant reduction in pain, stiffness, swelling, and redness, while promoting Samshodhana and restoring Dosha equilibrium, thus enhancing overall health and systemic inflammation.
