Clustered around the temples or one side of the head, migraine headaches affect over a billion people worldwide—and for many, conventional therapies fall short. In traditional Chinese medicine (TCM), migraine is classified under syndromes such as “brain wind” (nao feng), “head wind” (shou feng), and “unilateral or bilateral headache” (pian zheng tou tong). Rooted in centuries of clinical observation, TCM views migraine not as a single entity but as a dynamic pattern of disharmony—often involving wind invasion, blood stasis, qi and blood deficiency, phlegm-heat, or liver yang rising.
The foundational text Huangdi Neijing first documented migraine as a distinct condition, attributing its onset to both external pathogenic factors—such as wind, cold, or dampness—and internal imbalances like emotional strain or constitutional weakness. Later, Qing Dynasty physician Wu Qian expanded this framework in Yi Zong Jin Jian, noting that right-sided headaches often reflect qi stagnation or phlegm-heat, while left-sided pain frequently signals blood deficiency compounded by wind. This nuanced differentiation remains central to modern TCM diagnosis and treatment planning.
Contemporary research has identified several herb pairs—known as “drug pairs” or “yao dui”—that recur across classical formulas and modern clinical practice for migraine. Among the most extensively studied are Chuanxiong–Danggui (Ligusticum chuanxiong–Angelica sinensis), Baizhi–Chuanxiong (Angelica dahurica–Ligusticum chuanxiong), and Tianma–Chuanxiong (Gastrodia elata–Ligusticum chuanxiong). Of these, the Chuanxiong–Danggui combination stands out for its dual action: Chuanxiong, acrid and warm, moves qi and invigorates blood circulation—particularly upward to the head—while Danggui nourishes and harmonizes the blood, alleviating pain rooted in deficiency and stasis. Together, they exemplify the TCM principle of “activating blood while nourishing it,” a strategy especially relevant in chronic migraine with blood-deficiency and blood-stasis patterns.
This rationale underpins Shunaixin Dripping Pills (Shu Nao Xin), a State Drug Administration–approved proprietary Chinese medicine indicated specifically for migraine associated with blood deficiency and blood stasis. A multicenter, randomized, double-blind, controlled trial demonstrated that Shunaixin Dripping Pills significantly outperformed comparator therapy in reducing headache intensity and duration, decreasing attack frequency, and improving associated symptoms—including photophobia, phonophobia, dizziness, insomnia, and signs of microcirculatory impairment such as cyanotic lips and nails. Importantly, no serious adverse events were reported, supporting its favorable safety profile in clinical use.
Pharmacological investigations further validate this synergy: network pharmacology analyses suggest the Chuanxiong–Danggui pair contains 56 bioactive compounds targeting 187 migraine-related molecular sites. Its mechanisms appear to converge on key pathways—including TNF/IL-17 signaling and eNOS/nitric oxide regulation—modulating neuroinflammation, neuronal excitability, cerebral perfusion, and central pain processing.
Despite promising evidence, clinicians emphasize that herbal intervention must be guided by individualized TCM pattern diagnosis—not symptom matching alone. Self-prescribing or altering dosages without professional oversight risks inefficacy or unintended interactions. Complementary lifestyle measures—including wind protection for the head and neck, stress reduction techniques, and psychological support for comorbid anxiety or depression—are integral to sustainable management. As integrative neurology advances, rigorously studied herb pairs like Chuanxiong–Danggui offer a compelling model for mechanism-informed, patient-centered migraine care.
