Qing Ying Tang modified(LPI) is designed for individuals experiencing deep, lingering inflammation that has penetrated beyond the surface and is now affecting the blood level, nervous system, or cognitive function. It is especially suited for those with burning or low-grade fevers, night sweats, vivid or disturbing dreams, restless sleep, mental agitation and irritability, and signs of systemic heat such as flushing, dry mouth and thirst, indistinct erythema and purpura, and/or a crimson tongue. Modified versions of this formula are also used in presentations involving brain fog, emotional volatility, migratory or internal heat pain, and the sense that inflammation is “trapped” deep in the body or mind. In modern clinical contexts, it is particularly useful for post-viral syndromes, autoimmune flare states, or neuroinflammatory patterns where the inflammation is no longer easily expressed outward but continues to smolder internally. Qing Ying Tang (Modified) clears heat from the Ying (nutritive) and Blood levels, cools the Heart, and calms the shen—helping to resolve deep heat, quiet the mind, and bring clarity back to the system.
