Overview
Yiqi Yangyin Liyan formula is a traditional Chinese medicine (TCM) herbal combination used primarily for its purported benefits in tonifying qi (vital energy), nourishing yin, and benefiting the throat. It is typically administered as a decoction. The formulation is composed of multiple herbs; while the exact composition may vary by source or clinical context, it generally includes ingredients such as milkvetch root (Astragalus membranaceus), glehnia root (Glehnia littoralis), asparagus root (Asparagus cochinchinensis), lilyturf root (Ophiopogon japonicus), glossy privet fruit (Ligustrum lucidum), and others[1]. The mechanism of action is not fully elucidated but is believed to involve immunomodulatory effects, anti-inflammatory actions, and support for mucosal health according to TCM theory. Clinically, it has been studied in combination with other therapies for conditions such as IgA nephropathy with pharyngeal inflammation[5], chronic pharyngitis, tonsillitis[6], and potentially other inflammatory or immune-mediated diseases affecting the throat.
