Chinese Pine (Pinus tabuliformis and related Pinus species) has a history of use in Traditional Chinese Medicine (TCM), primarily for its resin ("pine resin" or "turpentine") and needles, which are believed to have expectorant, anti-inflammatory, and antimicrobial properties. In TCM, preparations from pine parts have been used to address respiratory ailments, including cough and sore throat, and occasionally laryngitis, often as part of multi-herb formulas. However, the evidence for its efficacy in treating laryngitis specifically is limited to traditional use and anecdotal reports. There are no high-quality clinical trials or extensive pharmacological studies directly supporting the use of Chinese Pine for laryngitis in the biomedical literature. Any benefit is presumed based on its general anti-inflammatory or soothing effects on mucous membranes.

In summary, while Chinese Pine is cited in traditional practices for supporting throat and respiratory health, there is a lack of scientific validation or direct clinical evidence for its use in laryngitis. Its use for this condition relies on historical precedent rather than substantiated biomedical research.
