Standardizing preventative strategies in Kshavathu: The topical retention of allergens and purifying with saline protocol

Dear Editor, We read with great interest the recent case report by Sivabalaji et al., detailing the standalone management of Kshavathu (~allergic rhinitis) using Shunthyadi taila nasya along with oral Chitraka haritaki.[1] The authors demonstrated remarkable clinical improvement, evidenced by the significant reduction in absolute eosinophil count and serum immunoglobulin E levels.[1] While the pharmacological properties of Shunthyadi taila – specifically its antihistaminic and anti-inflammatory effects – are vital, we propose that the success of Nasya also relies on its mechanical role as a protective barrier.[2] To standardize this observation for seasonal prophylaxis, we rephrase the age-old Indian concept as a two-step protocol and termed it as the Topical Retention of Allergens and Purifying with Saline (TRAPS) method for ease of reference and communication. The first step, “Trap,” involves applying a thin lipid barrier – such as ghee, preferably Cow’s (Pratimarsha nasya) – to the nasal vestibule. This creates a mechanical trap that entangles pollens and fine particulates before they reach the sensitive respiratory mucosa. Beyond this physical barrier, ghee provides crucial biochemical support through Vitamin A, which is essential for maintaining the structural integrity of the epithelial lining,[3] and butyric acid, a short-chain fatty acid with documented anti-inflammatory properties that may dampen hyper-reactive responses of the nasal lining. The second step, “Purify,” ensures that these trapped allergens are cleared regularly via a twice-daily mechanical flush. It is preferable to use isotonic saline (0.9% NaCl) rather than plain tap water. Hypotonic water can cause osmotic cellular swelling and irritation, whereas sterile saline maintains physiological balance and effectively removes the risk of waterborne pathogens. This dual-action protocol integrates ancient preventative wisdom with modern mucosal immunology, aiming toward a more definitive management of allergic rhinitis.[4] By utilizing the mechanical “trapping” potential of lipid-based Nasya and the “purification” of saline flushes, clinicians can offer a practical, low-cost seasonal adjunct to the management strategies highlighted by Sivabalaji et al.[1] Financial support and sponsorship Nil.
