Lindera aggregata (Wu Yao) is primarily used in Traditional Chinese Medicine (TCM) for conditions related to "Qi stagnation," abdominal pain, and urinary issues. In traditional practice, it has also been included in compound formulas aimed at treating symptoms such as dizziness, often in the context of overall patterns involving internal dampness, Qi stagnation, or blood deficiency. The use of Lindera aggregata for dizziness is thus rooted in TCM theory, where dizziness is not considered a single disease but rather a symptom of underlying systemic imbalance. The herb is believed to help by promoting the movement of Qi and resolving stagnation, which, according to TCM, may help alleviate dizziness when it is associated with these patterns.

However, scientific validation for Lindera aggregata specifically treating dizziness is limited. Most modern pharmacological studies focus on its analgesic, anti-inflammatory, and possible antitumor effects. There are no high-quality clinical trials or robust pharmacological studies directly supporting its use for dizziness as defined in Western medicine. Therefore, its use for this indication is supported by tradition more than by modern evidence, earning a moderate rating of 2 out of 5 for supporting evidence (reflecting significant historical use but limited scientific validation).
