Sinex-Rx is a 16 Herb TCM-based formulation evolved frm the classical Xin Yin San/Cang Er Zi San sinus formula, designed to address acute and chronic rhinosinusitis, allergic rhinitis, and post nasal drip by combining wind-dispersing, nasal-opening, immune-tonifying, qi-moving, and damp-clearing herbs. The formula targets viral and bacterial triggers, IgE-mediated allergy, biofilm-associated chronic inflammation, and constitutional Wei-Qi deficiency in recurrent infections, while also providing sinus-headache relief and upper-airway protection.
