Ligusticum wallichii (commonly known as Chuanxiong or Szechuan lovage) has a long history in Traditional Chinese Medicine (TCM), where it is primarily used to promote blood circulation, dispel wind, and alleviate pain. Within the framework of TCM, it is thought to influence the flow of Qi and blood, which may have indirect effects on various body systems, including the nervous system. However, its direct use for modulating or supporting the Sympathetic Nervous System, as understood in Western biomedical terms, is not clearly documented in the scientific literature.

Some preclinical studies suggest that extracts of Ligusticum wallichii may have effects on vascular tone and stress response, possibly through modulation of catecholamine release or blood flow, which could have peripheral effects relevant to the sympathetic system. However, these findings are limited and not robustly linked to practical or clinical support of the Sympathetic Nervous System in humans. Most of the evidence for its use in this context is based on traditional use and extrapolation rather than direct scientific research demonstrating efficacy or mechanism.

In summary, while Ligusticum wallichii is a traditional herbal medicine with some potential relevance to circulatory and possibly stress-related conditions, there is only weak evidence (from tradition and limited preclinical data) to support its use specifically for the Sympathetic Nervous System as defined in modern biomedical science.
