Self-assembled nanoaggregates in Wuzhuyu decoction: formation, absorption, transport, and alleviation of chronic migraine.
Chin J Nat Med | 2026
Laboratory / animal studySummary
Self-assembled nanoaggregates (SANs) from herbal decoctions show promise as natural medicines. Wuzhuyu decoction (WZYD) is a traditional formula for treating migraines. This study focuses on how SANs in WZYD, called N-WZYDs, are formed. These aggregates arise from interactions among multiple herbal ingredients, especially Euodiae Fructus. N-WZYDs consist of proteoglycan scaffolds and small active components. In chronic migraine (CM) rat models, N-WZYDs relieved symptoms significantly. Their efficacy is similar to that of WZYD itself. This effect may relate to inhibiting the IL-33/ST2/TRPA1 signaling pathway. Transport studies in Caco-2 cells indicated some components are poorly absorbed. However, evodiamine and 6-gingerol are moderately absorbed and active in efflux. Intact N-WZYDs accumulate mainly in the intestines. They promote serotonin release from enterochromaffin cells more effectively than free molecules. This study highlights how N-WZYDs could improve treatments for chronic migraine. Clinical relevance: This research suggests that N-WZYDs may enhance migraine treatment by improving serotonin levels.
Key Learning Points
- Self-assembled nanoaggregates from herbal decoctions show potential as effective natural medicines for chronic migraines.
- Wuzhuyu decoction, a traditional formula, contains these nanoaggregates, which may significantly relieve migraine symptoms.
- The formation of these nanoaggregates is influenced by interactions among various herbal ingredients, particularly Euodiae Fructus.
- N-WZYDs may enhance serotonin release in the intestines, which could improve migraine treatment outcomes.
- Some components of N-WZYDs are poorly absorbed, but others like evodiamine and 6-gingerol show moderate absorption and activity.
