A Review of Arshoghna Mahakashaya in the Charaka Samhita

Arsha, one of the most prevalent ano-rectal disorders, can manifest at any stage of life  and is extensively described in Ayurvedic literature. These texts elucidate its etiology,  pathology, symptomatology, classifications, and therapeutic approaches. Arsha denotes  the abnormal proliferation of muscle tissue in various forms that arise in the rectum and  adjacent areas, often as a consequence of imbalances in the doshas associated with the  skin, muscle, and adipose tissues. Manifesting at the opening of the guda marga (anal  passage), Arsha can be as problematic as an adversary, even in its mildest manifestations,  leading to considerable discomfort and distress. The Mahakashaya, an Ayurvedic  classification of medications based on their therapeutic actions (Karmas), provides  valuable insights into the management of Arsha. Acharya Charaka categorizes Arsha into two types: Ardra (wet) and Shushka (dry). In the Charaka Samhita, Sutrastana,  Chapter 4, the Arshoghna Mahakashaya group enumerates ten potent herbs known for  their efficacy in the management of Arsha. These herbs include Kutaja, Bilva, Chitraka,  Shundi, Ativisha, Abhaya, Dhanvayasa, Daruharidra, Vacha, and Chavya. Each plant  in this category possesses specific Rasa (taste), Guna (qualities), Veerya (potency), and  Vipaka (post-digestive effect), which collectively contribute to its therapeutic efficacy  against Arsha. In the treatment of Arshas, Tikta, Katu, and Kashaya rasa pradhana  dravyas are of critical importance. These medications are classified based on their  pharmacological properties, thereby offering targeted relief to individuals affected by  this condition.
